Enabling or Disabling LLDP

Global LLDP Setting

Transmit and Receive Control

© Copyright Lenovo 2015
By default, LLDP is enabled on the CN4093. To turn LLDP off or on, use the
following command:
CN4093(config)# [no] lldp enable
The CN4093 can also be configured to transmit or receive LLDP information on a
port‐by‐port basis. By default, when LLDP is globally enabled on the switch,
CN4093 ports transmit and receive LLDP information (see the tx_rx option
below). To change the LLDP transmit and receive state, the following commands
are available:
CN4093(config)# interface port <x>
CN4093(config­if)# lldp admin­status tx_rx
CN4093(config­if)# lldp admin­status tx_only
CN4093(config­if)# lldp admin­status rx_only
CN4093(config­if)# no lldp admin­status
CN4093(config­if)# exit
To view the LLDP transmit and receive status, use the following commands:
CN4093(config)# show lldp port
CN4093(config)# show interface port <n> lldp
(Turn LLDP on or off globally)
