lldp neighbor-identity port-id
Use lldp neighbor-identity port-id to configure the port ID TLV criterion for neighbor validation.
Use undo lldp neighbor-identity port-id to restore the default.
Syntax
lldp neighbor-identity port-id port-id-subtype port-id
undo lldp neighbor-identity port-id
Default
No port ID TLV criterion is configured on an interface for neighbor validation.
Views

Layer 3 Ethernet interface view
Predefined user roles

Parameters
port-id-subtype: Specifies the port ID subtype. The value is an integer in the range of 1 to 7. The port ID subtype indicates the type of identifier used for the port. Table 65 lists the available port ID subtypes and the ID bases.
Table 65: Port ID subtypes
Port ID subtype | ID basis |
|---|---|
1 | Interface alias |
2 | Port component |
3 | MAC address |
4 | Network address |
5 | Interface name |
6 | Agent circuit ID |
7 | Locally assigned |
port-id: Specifies the port ID, a case-sensitive string of 1 to 255 characters.
Usage guidelines
The port ID TLV criterion configured on an interface takes effect only after the lldp neighbor-protection validation command is configured on the interface.
If you execute this command multiple times for an interface, the most recent configuration takes effect.
Examples
# Configure the port ID TLV on Ten-GigabitEthernet1/0/1 for neighbor validation.
<Sysname> system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] lldp neighbor-identity port-id 5 ten-gigabitethernet1/0/1
