display ppp compression iphc

Use display ppp compression iphc to display IP header compression (IPHC) statistics.

Syntax

display ppp compression iphc { rtp | tcp } [ interface interface-type interface-number ]

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

rtp: Displays IPHC RTP header compression statistics.

tcp: Displays IPHC TCP header compression statistics.

interface interface-type interface-number: Specifies an interface by its type and number. If you do not specify this option, the command displays IPHC statistics on all interfaces.

Usage guidelines

When IPHC applies to an MP link:

· If an MP template is used, such as a VT interface or a dialer interface, the associated VA interface performs IPHC. You can view the compression information on the VA interface.

· If an MP-group interface is used, the MP-group interface performs IPHC. You can view the compression information on the MP-group interface.

When IPHC applies to a normal PPP link, the physical interface performs IPHC. You can view the compression information on the physical interface.

undo ip pool pool-name [ start-ip-address [ end-ip-address ] ]

Default

No PPP address pool is configured.

Views

System view

Predefined user roles

network-admin

Parameters

pool-name: Specifies a name for the PPP address pool to be created, a case-sensitive string of 1 to 31 characters.

start-ip-address [ end-ip-address ]: Specifies an IP address range. If you do not specify the end-ip-address argument, the PPP address pool has only the start IP address.

group group-name: Specifies a group by its name to which the PPP address pool belongs. The group name is a case-sensitive string of 1 to 31 characters. If you do not specify this option, the group name is default (the default group).

Usage guidelines

The system supports multiple address spaces that each correspond to a VPN instance. The same IP addresses can exist in different address spaces.

Each address space is represented by a group. One group can contain multiple PPP address pools, but one PPP address pool can belong to only one group.

One PPP address pool can contain multiple IP address ranges. You can execute this command multiple times to specify multiple IP address ranges for a PPP address pool. A PPP address pool can contain a maximum of 65535 IP addresses, and so can an IP address range.

IP address ranges in different groups can be overlapping, but those in the same group cannot.

Changes to a PPP address pool do not affect assigned IP addresses. For example, if you delete a PPP address pool from which an IP address has been assigned, the IP address can still be used.

When assigning IP address to users through a PPP address pool, make sure the PPP address pool excludes the gateway IP address of the PPP address pool.

Examples

# Configure PPP address pool aaa that contains IP addresses 129.102.0.1 through 129.102.0.10 for group a.

<Sysname> system-view

[Sysname] ip pool aaa 129.102.0.1 129.102.0.10 group a

Predefined user roles

network-admin

Parameters

pool-name: Specifies an existing PPP address pool by its name, a case-sensitive string of 1 to 31 characters.

ip-address: Specifies a gateway address for the PPP address pool.

vpn-instance vpn-instance-name: Specifies an existing MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the specified gateway belongs to the public network.

Usage guidelines

An interface on a BRAS must have an IP address before it can assign an IP address from a PPP or DHCP address pool to a client. This command enables interfaces that have no IP address to use a gateway address for IPCP negotiation and address allocation.

When you configure a gateway address for a PPP address pool, follow these restrictions and guidelines:

· If you also specify an IP address for an interface, the interface uses its own IP address to perform IPCP negotiation.

· You can specify only one gateway address for a PPP address pool. Different PPP address pools must have different gateway addresses (different combinations of ip-address and vpn-instance-name).

· You can specify any gateway address for a PPP address pool.

Examples

# Specify gateway address 1.1.1.1 for PPP address pool aaa.

<Sysname> system-view

[Sysname] ip pool aaa gateway 1.1.1.1

normal-logout: Specifies normal logout logs.

abnormal-logout: Specifies abnormal logout logs.

Usage guidelines

IMPORTANT:

Typically, disable this feature to prevent excessive PPP log output.

‌

The PPP user logging feature enables the device to generate PPP logs and send them to the information center. Logs are generated after a user comes online, goes offline, or fails to come online. A log entry contains information such as the username, IP address, interface name, inner VLAN, outer VLAN, MAC address, and failure causes. For information about the log destination and output rule configuration in the information center, see Network Management and Monitoring Configuration Guide.

When you execute this command without specifying any keyword, this command enables or disables logging for login successes, login failures, normal logouts, and abnormal logouts.

In a VSRP environment, no log is output when the access interface of a user goes down. For more information about VSRP, see VSRP in High Availability Configuration Guide.

Parameters

chap: Uses CHAP authentication.

ms-chap: Uses MS-CHAP authentication.

ms-chap-v2: Uses MS-CHAP-V2 authentication.

pap: Uses PAP authentication.

call-in: Authenticates the call-in users only. This keyword can be configured when the local end acts as the receiving end of DDR calls. For more information about DDR, see Layer 2—WAN Access Configuration Guide.

domain isp-name: Specifies the ISP domain name for authentication, a case-insensitive string of 1 to 255 characters. The ISP domain name cannot be d, de, def, defa, defau, defaul, or default.

default enable isp-name: Specifies the default ISP domain name for authentication, a case-insensitive string of 1 to 255 characters.

Usage guidelines

PPP authentication includes the following categories:

· PAP—Two-way handshake authentication. The password is in plain text or cipher text.

· CHAP—Three-way handshake authentication. The password is in plain text or cipher text.

· MS-CHAP—Three-way handshake authentication. The password is in cipher text.

· MS-CHAP-V2—Three-way handshake authentication. The password is in cipher text.

You can configure multiple authentication modes.

In any PPP authentication mode, AAA determines whether a user can pass the authentication through a local authentication database or an AAA server. For more information about AAA authentication, see Security Configuration Guide.

If multiple ISP domains are available, the ISP domains are used in the following order:

1. ISP domain specified by the domain isp-name option in this command.

Associate a PPP address pool with this ISP domain for address allocation if necessary.

2. ISP domain contained in the username.

If the ISP domain does not exist on the local device, the user's access request is denied.

3. ISP domain specified by the domain default enable isp-name option in this command.

4. Default system ISP domain.

You can use the domain default command to configure the default system ISP domain. If no system default ISP domain is configured, ISP domain system is used.

For authentication on a dialup interface, configure authentication on both the physical interface and the dialer interface. When a physical interface receives a DDR call request, it first initiates PPP negotiation and authenticates the dial-in user. Then it passes the call to the upper layer protocol.

network-admin

Parameters

nonstandard: Specifies the nonstandard encapsulation format. If you do not specify this keyword, packets are encapsulated in standard format. You must specify this keyword when the device communicates with a non-H3C device. If you specify this keyword, this command enables RTP header compression.

Usage guidelines

IPHC includes RTP header compression and TCP header compression.

Enabling or disabling IPHC enables or disables both RTP header compression and TCP header compression.

To use IPHC, you must enable it on both sides of a PPP link.

When you enable IPHC on a VT, dialer, or ISDN interface, the setting does not immediately take effect. For the setting to take effect, execute the shutdown and then undo shutdown commands on the interface or its bound physical interface.

Examples

# Enable IPHC on Serial 2/1/0.

Views

Interface view

Predefined user roles

network-admin

Parameters

number: Specifies the maximum number of connections for which an interface can perform RTP header compression. The value range for this argument is 3 to 1000:

· When the number argument is set to a value less than or equal to 256, packets are compressed in the format of COMPRESSED RTP 8.

· When the number argument is set to a value greater than 256, packets are compressed in the format of COMPRESSED RTP 16.

Usage guidelines

RTP is a connection-oriented protocol. An interface can accommodate multiple RTP connections.

RTP header compression occupies memory resources for maintaining connection information. This command can limit memory resources used by compression. For example, if you set the limit to 3, RTP header compression only applies to a maximum of three RTP connections.

After you execute this command, you must shut down and then bring up the interface to make the command take effect.

You can configure this command only when IPHC is enabled. The configuration is removed after IPHC is disabled.

Parameters

number: Specifies the maximum number of connections for which an interface can perform TCP header compression. The value range for this argument is 3 to 256.

Usage guidelines

TCP is a connection-oriented protocol. A link can accommodate multiple TCP connections.

TCP header compression occupies memory resources for maintaining connection information. This command can limit memory resources used by compression. For example, if you set the limit to 3, TCP header compression only applies to a maximum of three TCP connections.

After you execute this command, you must shut down and then bring up the interface to make the command take effect.

You can configure this command only when IPHC is enabled and packets are encapsulated in standard format. The configuration is removed after IPHC is disabled or packets are encapsulated in nonstandard format.

Usage guidelines

You can configure an interface to accept the DNS server IP addresses assigned by the peer, through which domain names can be resolved for the device.

Typically, the server assigns a DNS server address to a client in PPP negotiation only when the client is configured with the ppp ipcp dns request command. Some servers, however, forcibly assign DNS server addresses to clients. You must configure the ppp ipcp dns admit-any command on the client devices to accept the DNS server addresses.

Examples

# Configure Serial 2/1/0 to accept DNS server IP addresses allocated by the peer.

<Sysname> system-view

[Sysname] interface serial 2/1/0

Predefined user roles

network-admin

Parameters

ip-address: Specifies the destination IP address of the PPP address pool route, in dotted decimal notation.

mask-length: Specifies a mask length for the IP address, in the range of 0 to 32.

mask: Specifies a mask for the IP address, in dotted decimal notation.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the PPP address pool route applies to the public network.

Usage guidelines

The BRAS uses PPP address pool routes to control downlink traffic forwarding.

After you configure a PPP address pool route, the BRAS generates a static blackhole route destined for the specified network. All traffic matching the blackhole route is discarded. When a legal user logs in, the BRAS adds a host route destined for the specified network. In addition, the BRAS uses a dynamic routing protocol to redistribute the PPP address pool route to the upstream device.

Figure 1 Network diagram for the PPP address pool route

Make sure the destination network of the PPP address pool route includes the PPP address pool. You can execute this command multiple times to configure multiple PPP address pool routes.

Examples

# Configure the PPP address pool route as 2.2.2.2/24.

Parameters

milliseconds: Specifies the LCP negotiation delay timer in the range of 1 to 10000 milliseconds.

Usage guidelines

If two ends of a PPP link vary greatly in the LCP negotiation packet processing rate, configure this command on the end with a higher processing rate. The LCP negotiation delay timer prevents frequent LCP negotiation packet retransmission. After the physical layer comes up, PPP starts LCP negotiation when the delay timer expires. If PPP receives LCP negotiation packets before the delay timer expires, it starts LCP negotiation immediately.

Examples

# Set the LCP negotiation delay timer to 130 milliseconds.

Predefined user roles

network-admin

Parameters

ip-address: Specifies the IP address to be assigned to the client.

pool pool-name: Specifies a PPP or DHCP address pool by its name from which an IP address is assigned to the client. The pool name is a case-sensitive string of 1 to 31 characters.

Usage guidelines

This command can be used when the local interface is configured with an IP address, but the peer has no IP address. To enable the peer to accept the IP address assigned by the local interface (server), you must configure the ip address ppp-negotiate command on the peer to make the peer act as a client.

This command enables the local interface to forcibly assign an IP address to the peer. If the peer is not configured with the ip address ppp-negotiate command but configured with an IP address, the peer will not accept the assigned IP address. This results in an IPCP negotiation failure.

PPP supports IP address assignment from a PPP or DHCP address pool, but the PPP address pool takes precedence over the DHCP address pool. For example, if you use a pool name that identifies both a PPP address pool and a DHCP address pool, the system uses only the PPP address pool for address assignment.

To make the configuration of the remote address command take effect, configure this command before the ip address command, which triggers IPCP negotiation. If you configure the remote address command after the ip address command, the server assigns an IP address to the client during the next IPCP negotiation.

After you use the remote address command to assign an IP address to the client, you can configure the remote address command again or the undo remote address command for the peer. However, the new configuration does not take effect until the next IPCP negotiation.

Examples

# Specify the IP address to be assigned to the client as 10.0.0.1 on Serial 2/1/0.

<Sysname> system-view

[Sysname] interface serial 2/1/0

[Sysname-Serial2/1/0] remote address 10.0.0.1

Views

Interface view

Predefined user roles

network-admin

Parameters

callingnum: Uses the calling numbers as the DHCP client IDs. The calling numbers are carried in the calling number AVPs in L2TP negotiation packets. A calling number is formed by the user MAC address and the VLAN to which the user belongs. For example, if the MAC address of a user is 000f-e235-dc71, and the inner VLAN and outer VLAN of the user are VLAN 1 and VLAN 2, respectively, the calling number of the user is 000f-e235-dc71-00010002.

username: Uses the PPP usernames as the DHCP client IDs.

Usage guidelines

By default, a PPP client randomly selects a DHCP client ID when the PPP client requests an IP address through DHCP. In this case, the DHCP server cannot assign specific IP addresses to specific clients based on client IDs. For the DHCP server to assign specific IP addresses to specific clients based on client IDs, use this command to configure the calling numbers or usernames as the DHCP client IDs.

When PPP usernames are used as the DHCP client IDs, make sure different users use different PPP usernames to come online.

Parameters

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

Usage guidelines

This command is supported on distributed devices and IRF-capable centralized devices.

Specify traffic processing slots if a feature requires that all traffic on an VA interface be processed on the same slot.

For high availability, you can specify one primary and one backup traffic processing slot by using the service command and the service standby command, respectively.

To avoid processing slot switchover, specify the primary slot before specifying the backup slot. If you specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot immediately after you specify the primary slot.

If you specify both primary and backup slots for an interface, traffic on that interface is processed as follows:

· The backup slot takes over when the primary slot becomes unavailable. The backup slot continues to process traffic for the interface after the primary slot becomes available again. The switchover will not occur until the backup slot becomes unavailable.

· When no specified traffic processing slots are available, the traffic is processed on the slot at which it arrives. Then, the processing slot that first becomes available again takes over.

If you do not specify a primary or a backup traffic processing slot for an interface, traffic on that interface is processed on the slot at which the traffic arrives.

Examples

# (In standalone mode.) Specify slot 2 as the primary traffic processing slot for the VA interfaces on Virtual-Template 10.

<Sysname> system-view

[Sysname] interface virtual-template 10

The keepalive interval is 10 seconds on an interface.

Views

Interface view

Predefined user roles

network-admin

Parameters

seconds: Specifies the interval for sending keepalive packets, in the range of 0 to 32767 seconds. The value 0 disables an interface from sending keepalive packets. In this case, the interface can respond to keepalive packets from the peer.

Usage guidelines

An interface sends keepalive packets at keepalive intervals to detect the availability of the peer. If the interface receives no response to keepalive packets when the keepalive retry limit is reached, it determines that the link fails and reports a link layer down event.

To set the keepalive retry limit, use the timer-hold retry command.

On a slow link, increase the keepalive interval to prevent false shutdown of the interface. This situation might occur when keepalive packets are delayed because a large packet is being transmitted on the link.

Examples

# Set the keepalive interval to 20 seconds on Serial 2/1/0.

<Sysname> system-view

[Sysname] interface serial 2/1/0

[Sysname-Serial2/1/0] timer-hold 20

Predefined user roles

network-admin

Parameters

authentication: Uses the username for MP binding.

both: Uses both the username and the endpoint descriptor for MP binding.

descriptor: Uses the endpoint descriptor for MP binding.

Usage guidelines

The username is obtained from the peer during PAP, CHAP, MS-CHAP, or MS-CHAP-V2 authentication. The endpoint descriptor, which uniquely identifies a device, is obtained from the peer during LCP negotiation. Based on the username or endpoint descriptor, the system can locate the corresponding VT interface and create an MP bundle according to the template.

The descriptor mode cannot differentiate users. To bind users to different bundles, use the both mode.

The authentication mode cannot differentiate peer devices. When multiple peer devices exist, use the both mode.

Predefined user roles

network-admin

Parameters

endpoint: Specifies the content of the endpoint option, a case-sensitive string of 1 to 20 characters.

Usage guidelines

The endpoint option (terminal descriptor) is negotiated during MP LCP negotiation.

When MP is configured by using a VT interface, an MP endpoint bases its link binding decisions on the remote endpoint descriptors, and assigns the links that receive the same endpoint descriptor to the same bundle. To avoid incorrect link binding on a VT interface, make sure the link descriptors used by different devices are unique. You must reconfigure an endpoint descriptor for a device if the default endpoint descriptor (device name) cannot uniquely identify the MP bundle at the remote end.

When MP is configured by using an MP-group interface, the negotiating endpoints do not base their binding decisions on the endpoint descriptor. By default, the endpoint descriptor of an interface in an MP-group is the MP-group interface name. If you configure an endpoint descriptor for the interface, the configured MP endpoint descriptor takes effect.

If the endpoint descriptor exceeds 20 bytes, the first 20 bytes are taken as the endpoint descriptor.

Examples

# Configure the endpoint descriptor of Serial 2/1/0 as 123456.

<Sysname> system-view

[Sysname] interface serial 2/1/0

[Sysname-Serial2/1/0] ppp mp endpoint 123456

Usage guidelines

If the peer device does not support fragment reassembly, you must configure the ppp mp fragment disable command to disable MP fragmentation on the local device. This enables the two devices to communicate. After that, outgoing packets are not fragmented, but they still carry an MP sequence number and fragment tag.

After you configure the ppp mp fragment disable command on an interface, the settings configured with the ppp mp lfi enable and ppp mp min-fragment commands do not take effect on the interface.

When the minimum number of PPP links is set to a non-zero value, subsequent MP dial-up operations will not depend on traffic detection, but existing dial-up connections will be removed upon timeout.

The min-bind-num argument cannot be greater than the maximum number set with the ppp mp max-bind command.

Examples

# Set the minimum number of PPP links in an MP bundle to 4 on Dialer 0.

<Sysname> system-view

[Sysname] interface dialer 0

[Sysname-Dialer0] ppp mp min-bind 4

Parameters

size: Specifies the minimum MP packet fragmentation size in the range of 128 to 1500 bytes. Outgoing MP packets less than the minimum value will not be fragmented, and those greater than or equal to the minimum value will be fragmented.

Usage guidelines

If MP binding is implemented through hardware (for example, CPOS chip), the minimum MP packet fragmentation size varies with chips. The minimum MP packet fragmentation size on certain chips can only be 128, 256, or 512 bytes. To successfully create the MP bundle and establish the sub-channel LCP link, make sure the setting configured with the ppp mp min-fragment command conforms to the hardware specifications.

Examples

# Set the minimum MP packet fragmentation size to 500 bytes on MP-group 2/0/0.

Predefined user roles

network-admin

Usage guidelines

This command applies to the incoming direction only. To enable the local end to transmit packets with short sequence numbers, configure this command on the remote end.

The sequence number format (long or short) of an MP bundle depends on the configuration of the first channel joining the MP bundle.

To negotiate the use of short sequence numbers on a dialer MP bundle, configure the command on the dialer interfaces and the ISDN D channels. To negotiate the use of short sequence numbers on a common MP bundle, use the command on all its channels. The command will cause PPP re-negotiation.

Examples

# Configure the short sequence number header format of MP in the incoming direction of Serial 2/1/0.

<Sysname> system-view

[Sysname] interface serial 2/1/0

[Sysname-Serial2/1/0] ppp mp mp-group 2/0/0

network-admin

Parameters

size: Specifies the MP sort buffer size factor in the range of 1 to 64.

Usage guidelines

The MP sort buffer size = the number of channels in the current MP bundle × size. You can use the display ppp mp command to view the number of member channels in an MP bundle. If the calculated MP sort buffer size is 20, the MP sort buffer can sort 20 packets.

When MP is used, the received packets might be out of order. The sort buffer is used to re-sort packets. A large sort buffer results in better re-sorting but increases delay. For voice packets, the transmission delay should be minimized.

Examples

# Set the MP sort buffer size factor to 64 on MP-group 2/0/0.

<Sysname> system-view

[Sysname] interface mp-group 2/0/0

[Sysname-MP-group2/0/0] ppp mp sort-buffer-size 64

Parameters

seconds: Specifies the timer for MP to wait for the expected fragment, in the range of 1 to 255 seconds.

Usage guidelines

A receiving end puts the received fragments in the buffer and reassembles them when it receives all the packet's fragments. You can configure a timer for MP to wait for the expected fragments. When the receiving end receives the first fragment of a packet, it starts the timer. When the timer expires, the system checks whether or not all fragments have arrived. If they have all arrived, the system reassembles the fragments. If they have not all arrived, the system discards all received fragments to release the buffer space.

Examples

# Set the timer for MP to wait for the expected fragment to 20 seconds on MP-group 2/0/0.

<Sysname> system-view

[Sysname] interface mp-group 2/0/0

Parameters

username: Specifies a username, a case-sensitive string of 1 to 80 characters.

bind virtual-template number: Specifies a VT interface by its number in the range of 0 to 4095.

Usage guidelines

This command associates a username with a VT interface. After the user passes authentication, the system uses the settings on the VT interface to create an MP bundle and a VA interface to transmit data.

You can configure the following parameters for a VT interface:

· Local IP address and the peer IP address (or address pool).

· ppp mp-commands.

Examples

# Associate username user 1 with Virtual-Template 1, and set the IP address of the VT interface to 202.38.60.1/24.

Views

Predefined user roles

network-admin

Parameters

minimum value: Specifies the minimum MRU in the range of 64 to 1500 bytes.

Usage guidelines

To support an MTU larger than 1492, PPPoE adds the PPP-Max-Payload option during PPPoE negotiation. This option identifies the MTU for the current PPPoE session. If the MTU is larger than 1492, PPP uses the MTU as the MRU during LCP negotiation, and reports the MTU after negotiation.

MRU verification prevents the negotiated MRU from exceeding the receiving and sending capabilities of the interface. If the negotiated MRU is larger than 1492, the PPPoE server sends an echo request that has the same size as the negotiated MRU. If the PPPoE server receives a reply, it uses the MRU as the MTU. If the PPPoE server fails to receive a reply, the following situations occur:

· If the minimum MRU is configured, the PPPoE server sends a packet that has the same size as the minimum MRU.

· If the minimum MRU is not configured, the PPPoE server sends a packet that has the same size as the negotiated MRU.

If the second verification still fails, the PPPoE server tears down the link.

NCP negotiation starts after the MRU verification succeeds.

Examples

# Enable MRU verification for PPPoE and set the minimum MRU to 1200 bytes on Virtual-Template 10.

Parameters

cn-163: Specifies the China Telecom 163 format for the BAS information. If you do not specify this keyword, BAS information in the China Telecom format is included.

Usage guidelines

The bas-info formats include China Telecom and China Telecom 163.

The China Telecom format is {atm|eth|trunk} NAS_slot/NAS_subslot/NAS_port:XPI.XCI. The format refers to the user access interface information on the BAS device, including upstream interface, VLAN, and VPI/VCI information:

· When ATM/DSL is used, XPI.XCI refers to VPI/VCI information.

· When Ethernet/DSL is used, XPI.XCI refers to VLAN information.

For example, eth 1/0/1:4096.2345 includes the following user access interface information:

· The type of the upstream interface is Ethernet interface.

· The interface is located at slot 1, subslot 0, and port 1.

· The outer VLAN ID is 4096 (which means an invalid VLAN), and the inner VLAN ID is 2345.

Table 16 shows the China Telecom 163 format, where:

· NAS_slot, NAS_subslot, and NAS_port refer to the numbering information of the PPPoE user access interface on the BAS device.

· vpi and vci refer to VPI and VCI information.

· vlanid and vlanid2 refer to inner VLAN and outer VLAN, respectively. The value for the vlanid of the primary interface is fixed at 0.

Table 16 BAS information in China Telecom 163 format

Interface type	Format
ATM interface‌	slot=NAS_slot;subslot=NAS_subslot;port=NAS_port;vpi=XPI;vci=XCI;
Primary interface or interface that does not carry inner VLAN or outer VLAN information.	slot=NAS_slot;subslot=NAS_subslot;port=NAS_port;vlanid=VLAN id;
Interface that carries inner VLAN and outer VLAN information.	slot=NAS_slot;subslot=NAS_subslot;port=NAS_port;vlanid=VLAN id;vlanid2=VLAN id2;

‌

This command determines the content of the NAS-Port-ID attribute that the PPPoE server delivers to the RADIUS server.

· If the cn-163 keyword is specified, the PPPoE server automatically inserts the corresponding BAS information before the parsed circuit-id. Then it sends the combination of the bas-info and circuit-id as the NAS-Port-ID attribute to the RADIUS server.

· If the cn-163 keyword is not specified, the PPPoE server creates a new circuit-id in China Telecom format. Then it sends the new circuit-id as the NAS-Port-ID attribute to the RADIUS server. The new circuit-id contains the corresponding BAS information and the DSLAM user access information in the original circuit-id.

If this command is not executed, the NAS-Port-ID attribute that the PPPoE server delivers to the RADIUS server is determined by the pppoe-server access-line-id content command.

The RADIUS server cannot correctly parse a NAS-Port-ID attribute that includes the remote-id and BAS information. When you configure this command together with the pppoe-server access-line-id trust command, make sure the NAS-Port-ID attribute sent to the RADIUS sever does not include the remote-id.

Examples

# Configure the NAS-Port-ID attribute to automatically include BAS information on GigabitEthernet 1/0/1.

The TR-101 format is Access-Node-Identifier atm slot/port:vpi.vci for ATM/DSL, and is Access-Node-Identifier eth slot/port[:vlan-id] for Ethernet/DSL. The entire ID refers to the user access information on the DSLAM, where

· Access-Node-Identifier refers to the identifier of the DSLAM.

· The remainder refers to information about the user access interface on the DSLAM.

The China Telecom format is AccessNodeIdentifier/ANI_rack/ANI_frame/ANI_slot/ANI_subslot/ANI_port[:ANI_XPI.ANI_XCI]. The format refers to user access information on the DSLAM, including DSLAM identifier and user access interface.

For example, the circuit-id guangzhou001/1/31/63/31/127 includes the following information:

· The identifier of the access node DSLAM is guangzhou001.

· The rack number of the DSLAM is 1.

· The user access interface is located at port 127, subslot 31, slot 63, and frame 31.

Parameters

all: Sends both the circuit-id and remote-id.

separator: Specifies a separator that is one character long. By default, the value is a blank space. The circuit-id and remote-id are connected by the separator.

circuit-id: Sends only the circuit-id.

remote-id: Sends only the remote-id.

Usage guidelines

The PPPoE server on a BAS device uses the RADIUS NAS-Port-ID attribute to send the access line ID received from a DSLAM device to the RADIUS server. The access line ID contains the circuit-id and remote-id. The RADIUS server compares the received NAS-Port-ID attribute with the local line ID information to verify the location of the user.

For more information about the circuit-id, see the pppoe-server access-line-id circuit-id parse-mode command.

For more information about the remote-id, see pppoe-server access-line-id remote-id trans-format the command.

Do not use a character that exists in the circuit-id or remote-id as the separator. Otherwise, the RADIUS server might fail to parse the ID information.

This command determines the content of the NAS-Port-ID attribute only when the pppoe-server access-line-id bas-info command is not configured. Otherwise, the pppoe-server access-line-id bas-info command determines the content of the NAS-Port-ID attribute.

Examples

Parameters

minimum min-number: Specifies the minimum value for the PPP maximum payload, in the range of 64 to 4470 bytes. The default value is 1492 bytes.

maximum max-number: Specifies the maximum value for the PPP maximum payload, in the range of 64 to 4470 bytes. The default value is 1500 bytes. The max-number argument must be equal or greater than the min-number argument.

Usage guidelines

This command enables the PPPoE server to forward large PPP packets with a payload larger than 1492 bytes and reduces fragmentation. If the ppp-max-payload tag sent by the PPPoE client is within the tag range, the PPPoE server returns a PADO or PADS packet that includes the tag. If not, the PPPoE server considers the received packets invalid, and it does not return a PADO or PADS packet.

The jumboframe enable command can change the size of jumbo frames supported by the interface. The maximum size of the jumbo frames configured by the jumboframe enable command should be larger than the maximum value configured by the pppoe-server tag ppp-max-payload command.

Examples

# Enable the PPPoE server to support the ppp-max-payload tag and set the value for the PPP maximum payload to be in the range of 1494 to 1580 bytes on GigabitEthernet 1/0/1.

Parameters

Usage guidelines

Service names identify the traffic destined for PPPoE servers when multiple PPPoE servers are providing services on the network. A PPPoE client establishes a session with the target PPPoE server by using the following process:

1. The client broadcasts a PADI packet.

2. The server compares its service name with the service-name tag field of the PADI packet. The server sends a PADO packet to the client if either of the following conditions exists:

¡ The field matches the service name.

¡ No service name is configured.

3. The client sends a PADR packet to the server.

4. The server compares its service name with the service-name tag field of the PADR packet. The server sends a PADS packet and sets up a session with the client if either of the following conditions exists:

¡ The field matches the service name.

¡ No service name is configured.

Parameters

session-requests: Specifies the maximum number of PPPoE session requests from a user within the monitoring time. The value range is 1 to 100000.

session-request-period: Specifies the monitoring time in the range of 1 to 3600 seconds.

blocking-period: Specifies the blocking time in the range of 1 to 3600 seconds.

Usage guidelines

This command limits the rate at which a user (identified by MAC address) can create PPPoE sessions on an interface. If the number of PPPoE requests within the monitoring time exceeds the configured threshold, the device discards the excessive requests, and outputs log messages. If the blocking time is set to 0, the device does not block any requests, and it only outputs log messages.

The device uses a monitoring table and a blocking table to control PPP access rates.

· Monitoring table—Stores a maximum of 8000 monitoring entries. Each entry records the number of PPPoE sessions created by a user within the monitoring time. When the monitoring entries reach the maximum, the system stops monitoring and blocking session requests from new users. The aging time of monitoring entries is determined by the session-request-period argument. When the timer expires, the system starts a new round of monitoring for the user.

· Blocking table—Stores a maximum of 8000 blocking entries. The system creates a blocking entry if the access rate of a user reaches the threshold, and blocks requests from that user. When the blocking entries reach the maximum, the system stops blocking session requests from new users and it only outputs log messages. The aging time of the blocking entries is determined by the blocking-period argument. When the timer expires, the system starts a new round of monitoring for the user.

If the access rate setting is changed, the system removes all monitoring and blocking entries, and uses the new settings to limit PPPoE access rates.

Examples

# Limit the rate at which a user can create PPPoE sessions on GigabitEthernet 1/0/1.

Parameters

virtual-template template-number: Specifies an existing VT interface to use the VA pool.

va-pool va-volume: Specifies the maximum number of VA interfaces contained in the VA pool, in the range of 1 to 65534.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, a global VA pool is created. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card of an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, a global VA pool is created. (In IRF mode.)

Usage guidelines

The PPPoE server creates a VA interface for a PPPoE session to transmit packets between PPPoE and PPP, and removes the VA interface when the user goes offline. Creating and removing VA interfaces take time.

You can configure VA pools to improve the performance of PPPoE session establishment and termination. A VA pool contains a group of automatically numbered VA interfaces. The PPPoE server selects a VA interface from the pool for a requesting user and release the VA interface when the user goes offline. When a VA pool is exhausted, the system creates VA interfaces for new PPPoE sessions, and removes those VA interfaces when the users go offline.

On a VT interface, you can create one global VA pool and one regional VA pool per member device for interfaces bound with the VT interface.

· The global VA pool contains VA interfaces for logical interfaces that might span multiple devices, such as Ethernet aggregate interfaces.

· The regional VA pool contains VA interfaces for interfaces that do not span multiple devices, such as Ethernet interfaces.

When you configure a VA pool, follow these guidelines:

· To change the capacity of a VA pool, you must delete the previous configuration, and reconfigure the VA pool.

· Creating or removing a VA pool takes time. During the process of creating or removing a VA pool, users can go online or offline, but the VA pool does not take effect.

· If the system fails to create a VA pool because of insufficient resources, you can view the available resources by using the display pppoe-server va-pool command.

· VA pools are memory intensive. Set their capacity depending on your network requirements.

· Deleting a VA pool does not log off the users who are using VA interfaces in the VA pool.

Parameters

dial-bundle-number number: Specifies the dialer bundle number corresponding to a PPPoE session. A dialer bundle number uniquely identifies a PPPoE session. It can also be used as a PPPoE session ID. The value range for this argument is 0 to 1023.

no-hostuniq: Configures the client not to carry the Host-Uniq field in discovery packets. If you do not specify this keyword, the client carries the Host-Unique field. The Host-Unique field uniquely identifies a PPPoE client when an interface is configured with multiple PPPoE sessions. When the PPPoE server receives a packet with this field, it must include this field unmodified in the response packet. The device identifies the PPPoE client where the response packet belongs based on the Host-Unique field in the response packet.

Examples

# Establish a PPPoE session on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] pppoe-client dial-bundle-number 1

# Establish a PPPoE session on Virtual-Ethernet 0.

<Sysname> system-view

[Sysname] interface virtual-ethernet 0

[Sysname-Virtual-Ethernet0] pppoe-client dial-bundle-number 1

# Establish a PPPoE session on VLAN-Interface 1.
