For DCBX to work correctly, set the same DCBX version on the local port and peer port. As a best practice, set the highest version supported on both ends. IEEE Std 802.1Qaz-2011, DCBX Rev 1.01, and DCBX Rev 1.00 are in descending order.

After the configuration, LLDP frames sent by the local port carry information about the configured DCBX version. The local port and peer port do not negotiate the DCBX version.

When the DCBX version is autonegotiated, the version IEEE Std 802.1Qaz-2011 is preferentially negotiated.

Examples

# Set the DCBX version to Rev. 1.01 on interface HundredGigE 1/0/1.

<Sysname> system-view

[Sysname] interface hundredgige 1/0/1

[Sysname-HundredGigE1/0/1] dcbx version rev101

Parameters

agent: Specifies an LLDP agent type. If you do not specify an agent type, this command applies to the nearest bridge agent.

· nearest-customer: Specifies the nearest customer bridge agent.

· nearest-nontpmr: Specifies the nearest non-TPMR bridge agent.

ipv6: Specifies an IPv6 management address. If you do not specify this keyword, an IPv4 management address will be advertised.

ip-address: Specifies the management address to be advertised.

interface loopback interface-number: Specifies a loopback interface by its number in the range of 0 to 127. The IP address of the loopback interface will be advertised as the management address. The value range for the interface-number argument is 0 to 1023.

interface vlan-interface interface-number: Specifies a VLAN interface by is number in the range of 1 to 4094. The IP address of the VLAN interface will be advertised as the management address.

Usage guidelines

If you execute this command multiple times, the most recent configuration takes effect.

You can configure advertisement of the management address TLV globally or on a per-interface basis. The device selects the management address TLV advertisement setting for an interface in the following order:

1. Interface-based setting, configured by using the lldp tlv-enable command with the management-address-tlv keyword.

2. Global setting, configured by using the lldp global tlv-enable basic-tlv management-address-tlv command.

3. Default setting for the interface.

By default:

¡ The nearest bridge agent and nearest customer bridge agent advertise the management address TLV.

¡ The nearest non-TPMR bridge agent does not advertise the management address TLV.

The IPv4 or IPv6 address of the LLDP frame sending port will be advertised as the management address when the following conditions exist:

· The ip-address argument is not configured.

· The specified loopback or VLAN interface does not have an IPv4 or IPv6 address, or the specified interface does not exist.

If the LLDP frame sending port does not have an IPv4 or IPv6 address, the MAC address of the port will be advertised.

If you specify the ipv6 keyword, the management address is the IPv6 address. If you do not specify the ipv6 keyword, the management address is the IPv4 address.

Examples

# Enable advertisement of the management address TLV globally and set the advertised management address to 192.168.1.1.

Parameters

value: Sets the TTL multiplier in the range of 2 to 10.

Usage guidelines

The TTL TLV carried in an LLDPDU determines how long the device information carried in the LLDPDU can be saved on a recipient device.

By setting the TTL multiplier, you can set the TTL of locally sent LLDP frames. The TTL is expressed by using the following formula:

TTL = Min (65535, (TTL multiplier × LLDP frame transmission interval + 1))

As the expression shows, the TTL can be up to 65535 seconds.

Examples

# Set the TTL multiplier to 6.

Views

System view

Default command level

network-admin

Usage guidelines

By default, when the system receives an LLDP packet, it compares the PVID value contained in packet with the PVID configured on the receiving interface. If the two PVIDs do not match, a log message will be printed to notify the user.

You can disable PVID inconsistency check if different PVIDs are required on a link.

Examples

# Disable LLDP PVID inconsistency check.

<Sysname> system-view

[Sysname] lldp ignore-pvid-inconsistency

lldp management-address

Use lldp management-address to enable the device to generate an ARP or ND entry after receiving an LLDP frame that carries a management address TLV.

Predefined user roles

network-admin

Parameters

arp-learning: Generates an ARP entry if the received management address TLV contains an IPv4 address.

nd-learning: Generates an ND entry if the received management address TLV contains an IPv6 address.

vlan vlan-id: Specifies a VLAN ID. The value range for the vlan-id argument is 1 to 4094.

· In Layer 2 Ethernet interface view, specify the ID of the VLAN to which the generated ARP or ND entry belongs.

· In Layer 3 Ethernet/aggregate interface view, the Layer 3 Ethernet/aggregate interface is recorded as the output interface in the ARP or ND entry.

agent nearest-nontpmr: Specifies nearest non-TPMR bridge agents.

Usage guidelines

You can enable the device to generate both ARP entries and ND entries.

In Layer 2 Ethernet interface view, after you execute this command, the Layer 2 Ethernet interface is recorded as the output interface in the generated entries. The VLAN to which the entries belong is the VLAN specified by this command. The device cannot generate ARP or ND entries in one of the following situations:

· The specified VLAN or the corresponding VLAN interface does not exist.

· The VLAN interface to which the VLAN ID belongs is physically down.

In Layer 3 Ethernet/aggregate interface view, the Layer 3 Ethernet/aggregate interface is always recorded as the output interface, no matter whether you specify a VLAN ID.

This command must be executed together with the lldp source-mac vlan command. The lldp source-mac vlan command enables the device to use the MAC address of a VLAN interface instead of the egress interface's MAC address as the source MAC address of LLDP frames. This ensures that the LLDP neighbor can learn correct ARP or ND entries.

Examples

# Configure Layer 2 Ethernet interface HundredGigE 1/0/1 to generate an ARP entry after receiving an LLDP frame carrying an IPv4 management address TLV.

basic-tlv: Advertises basic LLDP TLVs.

management-address-tlv [ ipv6 ] [ ip-address | interface loopback interface-number ]: Advertises management address TLVs. The ipv6 keyword indicates that the management address to be advertised is in IPv6 format. The ip-address argument specifies the management address to be advertised. The interface loopback interface-number option specifies the management address as the IP address of a loopback interface specified by its number. By default, the following rules apply:

· When you execute the lldp tlv-enable command:

¡ For a Layer 2 Ethernet interface, the IPv4 or IPv6 address of a VLAN interface will be advertised as the management address when one of the following conditions exists:

- Both the ip-address argument and the interface loopback interface-number option are not configured.

- The specified loopback interface does not have an IPv4 or IPv6 address, or the specified loopback interface does not exist.

The VLAN interface belongs to a VLAN that meets the following requirements:

- In up state.

- The corresponding VLAN ID is the lowest among the VLANs permitted on the interface.

If you specify the ipv6 keyword, the IPv6 address of the VLAN interface will be advertised. If you do not specify the ipv6 keyword, both the IPv4 and IPv6 addresses of the VLAN interface will be advertised.

If none of the VLAN interfaces of the permitted VLANs is assigned an IPv4 or IPv6 address or all VLAN interfaces are down, the MAC address of the interface will be advertised.

¡ For a Layer 2 aggregate interface, the IPv4 or IPv6 address of a VLAN interface will be advertised as the management address if the ip-address argument is not configured.

The VLAN interface belongs to a VLAN that meets the following requirements:

- In up state.

- The corresponding VLAN ID is the lowest among the VLANs permitted on the interface.

If none of the VLAN interfaces of the permitted VLANs is assigned an IPv4 or IPv6 address or all VLAN interfaces are down, the MAC address of the interface will be advertised.

¡ For a Layer 3 Ethernet interface, the IPv4 or IPv6 address of the interface will be advertised when the following conditions exist:

- The ip-address argument is not configured.

- The specified loopback interface does not have an IPv4 or IPv6 address, or the specified loopback interface does not exist.

If you specify the ipv6 keyword, the IPv6 address of the interface will be advertised. If you do not specify the ipv6 keyword, both the IPv4 and IPv6 addresses of the interface will be advertised.

If the interface does not have an IPv4 or IPv6 address, the MAC address of the interface will be advertised.

¡ For a Layer 3 aggregate interface or management Ethernet interface, the IPv4 or IPv6 address of the interface will be advertised when the following conditions exist:

- The ip-address argument is not configured.

- The specified loopback interface does not have an IPv4 or IPv6 address, or the specified loopback interface does not exist.

If you specify the ipv6 keyword, the IPv6 address of the interface will be advertised. If you do not specify the ipv6 keyword, both the IPv4 and IPv6 addresses of the interface will be advertised.

If the interface does not have an IPv4 or IPv6 address, the MAC address of the interface will be advertised.

· When you execute the undo lldp tlv-enable command for a Layer 2/Layer 3 Ethernet interface, management Ethernet interface, or Layer 2/Layer 3 aggregate interface:

¡ If you do not specify ip-address, ipv6, or interface loopback interface-number, the interface does not advertise any management address TLVs.

¡ If you specify ip-address, ipv6, or interface loopback interface-number, the interface advertises the default management address TLVs.

port-description: Advertises port description TLVs.

system-capability: Advertises system capabilities TLVs.

system-description: Advertises system description TLVs.

system-name: Advertises system name TLVs.

dot1-tlv: Advertises IEEE 802.1 organizationally specific LLDP TLVs.

dcbx: Advertises the DCBX TLVs.

port-vlan-id: Advertises port VLAN ID TLVs.

protocol-vlan-id [ vlan-id ]: Advertises port and protocol VLAN ID TLVs. The vlan-id argument specifies a VLAN ID in the TLVs to be advertised. The VLAN ID is in the range of 1 to 4094, and the default is the lowest VLAN ID on the port.

vlan-name [ vlan-id-list ]: Advertises VLAN name TLVs. The vlan-id-list argument specifies a VLAN range in the TLVs to be advertised in the format of { vlan-id1 [ to vlan-id2 ] }&<1-10>. The value range for the vlan-id argument is 1 to 4094 and the value for vlan-id2 must be equal to or greater than the value for vlan-id1. &<1-10> indicates that you can specify up to 10 VLAN ID ranges. The default value for the vlan-id-list argument is the lowest VLAN ID on the port. If you do not specify a VLAN ID and the port is not assigned to any VLAN, the PVID of the port is advertised or the port cancels advertising all VLAN name TLVs.

management-vid [ mvlan-id ]: Advertises management VLAN ID TLVs. The mvlan-id argument specifies a management VLAN ID in the TLVs to be advertised. The management VLAN ID is in the range of 1 to 4094. If you do not specify this option, the value 0 is advertised, which means that the LLDP agent is not configured with a management VLAN ID.

link-aggregation: Advertises link aggregation TLVs.

dot3-tlv: Advertises IEEE 802.3 organizationally specific LLDP TLVs.

mac-physic: Advertises MAC/PHY configuration/status TLVs.

max-frame-size: Advertises maximum frame size TLVs.

power: Advertises power via MDI TLVs and power stateful control TLVs.

med-tlv: Advertises LLDP-MED TLVs.

capability: Advertises LLDP-MED capabilities TLVs.

inventory: Advertises the following TLVs: hardware revision, firmware revision, software revision, serial number, manufacturer name, model name, and asset ID.

power-over-ethernet: Advertises extended power-via-MDI TLVs.

location-id: Advertises location identification TLVs.

civic-address: Inserts the typical address information about the network device in location identification TLVs .

device-type: Sets a device type value in the range of 0 to 2:

· Value 0 specifies a DHCP server.

· Value 1 specifies a network device.

· Value 2 specifies an LLDP-MED endpoint.

country-code: Sets a country code defined in ISO 3166.

{ ca-type ca-value }&<1-10>: Configures address information. ca-type represents the address information type in the range of 0 to 255. ca-value represents address information, a string of 1 to 250 characters. &<1-10> indicates that you can specify up to 10 ca-type ca-value pairs.

elin-address: Inserts telephone numbers for emergencies in location identification TLVs.

tel-number: Sets the telephone number for emergencies, a string of 10 to 25 characters.

network-policy [ vlan-id ]: Advertises network policy TLVs. The vlan-id argument specifies the VLAN ID to be advertised, in the range of 1 to 4094.

Usage guidelines

Nearest bridge agents are not supported on aggregate interfaces.

You can enable the device to advertise multiple types of TLVs by using this command without the all keyword specified.

If the MAC/PHY configuration/status TLV is not advertisable, none of the LLDP-MED TLVs will be advertised whether or not they are advertisable. If the LLDP-MED capabilities TLV is not advertisable, the other LLDP-MED TLVs will not be advertised regardless of whether or not they are advertisable.

The port and protocol VLAN ID, VLAN name, and management VLAN ID TLVs in IEEE 802.1 organizationally specific LLDP TLVs can be configured only for nearest bridge agents. The configuration can be inherited by nearest customer bridge agents and nearest non-TPMR bridge agents.

A port can advertise VLAN name TLVs for a maximum of 10 VLAN IDs, because the maximum length of LLDP frames sent by a port is limited. If you use the vlan-name [ vlan-id-list ] option to specify many VLAN IDs for this command, the port might advertise only part of the specified VLAN IDs.
