disable: Specifies the Disable mode. A port in this mode does not send or receive LLDPDUs. 

rx: Specifies the Rx mode. A port in this mode receives LLDPDUs only. 

tx: Specifies the Tx mode. A port in this mode sends LLDPDUs only. 

txrx: Specifies the TxRx mode. A port in this mode sends and receives LLDPDUs. 

Use the lldp admin-status command to specify the LLDP operating mode for a port or all the ports in a 

port group. 

Use the undo lldp admin-status command to restore the default LLDP operating mode. 

The default LLDP operating mode is TxRx. 

# Configure the LLDP operating mode as Rx for Ethernet 1/0/1.

Ethernet interface view 

value: LLDP polling interval to be set, in the range 1 to 30 (in seconds). 

Use the lldp check-change-interval command to enable LLDP polling and set the polling interval. 

Use the undo lldp check-change-interval command to restore the default. 

By default, LLDP polling is disabled. 

With LLDP polling enabled, LLDP detects for local configuration changes periodically. A local 

configuration change triggers LLDPDU sending, through which neighboring devices can be informed of 

the configuration change timely. 

# Enable LLDP polling on Ethernet 1/0/1, setting the polling interval to 30 seconds.
