Enable LLDP Voice Authentication on a Specific Port

About this task

Perform this procedure to enable Link Layer Discovery Protocol (LLDP) voice authentication of IP phones on a specific port. If the system detects a phone through LLDP, then “eapol voice lldp-auth” configuration is applied on the port that is connected to the phone.

If you run the no auto-sense enable convert-to-config command, the system preserves the LLDP authentication configuration.

You cannot perform this configuration on Auto-sense ports. Use Auto-sense LLDP authentication to apply LLDP authentication on all Auto-sense ports in the VOICE state.

1. Enter GigabitEthernet Interface Configuration mode:

   enable

   configure terminal

   interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

   

   Note

   If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

2. Enable LLDP voice authentication on a specific port:

   eapol voice lldp-auth

Example

Enabling LLDP voice authentication on a specific port:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#interface gigabitEthernet 1/2
Switch:1(config-if)#eapol voice lldp-auth
