Use undo ppp lcp echo mru verify to disable MRU verification for PPPoE.

Syntax

undo ppp lcp echo mru verify

Default

MRU verification for PPPoE is disabled on a VT interface.

Views

VT interface view

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.

Predefined user roles

network-admin

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 6 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 6 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 0/0/1.

Parameters

cn-telecom: Specifies China Telecom format.

tr-101: Specifies TR-101 format.

Usage guidelines

The circuit-id formats include TR-101 and China Telecom.

The TR-101 format is Access-Node-Identifier atm frame/slot/subslot/port:vpi.vci for ATM/DSL, and is Access-Node-Identifier eth frame/slot/subslot/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 (where the frame field represents the chassis number).

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.

Parameters

name: Specifies an AC name, a case-sensitive string of 1 to 64 characters.

Usage guidelines

The PPPoE server sends its AC name in PADO packets. PPPoE clients choose a PPPoE server by AC name. The PPPoE clients on H3C devices cannot identify PPPoE servers by AC name.

The device does not support an AC name comprised of all blank spaces.

Examples

# Specify the AC name for the PPPoE server on GigabitEthernet 0/0/1 as pppoes.

pppoe-server tag ppp-max-payload

Use pppoe-server tag ppp-max-payload to enable the PPPoE server to support the ppp-max-payload tag and set a range for the tag on an interface.

Use undo pppoe-server tag ppp-max-payload to restore the default.

Syntax

pppoe-server tag ppp-max-payload [ minimum min-number maximum max-number ]

undo pppoe-server tag ppp-max-payload

Default

The PPPoE server does not support ppp-max-payload tag on an interface. The PPPoE server ignores the ppp-max-payload tag in PADI or PADS packets from clients, and returns a PADO or PADS packets without the ppp-max-payload tag.

Predefined user roles

network-admin

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 0/0/1.

<Sysname> system-view

Parameters

name: Specifies a service name, a case-sensitive string of 1 to 64 characters.

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.

Examples

# Set the service name to pppoes for the PPPoE server on GigabitEthernet 0/0/1.

undo pppoe-server throttle per-mac

Default

The PPPoE access rate is not limited on an interface.

Predefined user roles

network-admin

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 0/0/1.

Predefined user roles

network-admin

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.

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.

Examples

# Create a VA pool with a capacity of 1000 VA interfaces on Virtual-Template 2.
