Chapter 21 Configuring LLDP and LLDP-MED
Monitoring and Maintaining LLDP and LLDP-MED
This example shows how to enable a TLV on an interface when it has been disabled.
Switch#
configure terminal
Switch(config)#
interface GigabitEthernet1/0/1
Switch(config-if)#
lldp med-tlv-select inventory-management
Switch(config-if)#
end
LLDP and Ethernet Flow Points (EFPs)
For LLDP to peer with a neighbor on a port that has an Ethernet Virtual Connection (EVC) EFP service
instance configured, you need to enter the l2 protocol peer lldp service-instance configuration
command on the service instance. See the
“Configuring Ethernet Virtual Connections (EVCs)”
chapter
for more information on EFPs.
This example shows how to configure Layer 2 protocol peer on a service instance:
Switch (config)#
interface gigabitethernet0/1
Switch (config-if)#
switchport mode trunk
Switch (config-if)#
switchport trunk allowed vlan none
Switch (config-if)#
service instance
1
Ethernet
Switch (config-if-srv)#
encapsulation untagged
Switch (config-if-srv)#
l2protocol peer lldp
Switch (config-if-srv)#
bridge-domain 10
Switch (config-if-srv)#
end
Monitoring and Maintaining LLDP and LLDP-MED
To monitor and maintain LLDP and LLDP-MED on your device, perform one or more of these tasks,
beginning in privileged EXEC mode.
Step 3
lldp med-tlv-select tlv
Specify the TLV to enable.
Step 4
end
Return to privileged EXEC mode.
Step 5
copy running-config startup-config
(Optional) Save your entries in the configuration file.

packets being sent, and the delay time for LLDP to initialize on an interface.
show lldp entry
entry-name
Display information about a specific neighbor.
You can enter an asterisk (*) to display all neighbors, or you can enter the name
of the neighbor about which you want information.
