Enabling or Disabling LLDP

Global LLDP Setting

Transmit and Receive Control

© Copyright Lenovo 2017
By default, LLDP is enabled on the CN4093. To turn LLDP off or on, use the
following command:
CN 4093(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:
CN 4093(config)# interface port <x>
CN 4093(config-if)# lldp admin-status tx_rx (Transmit and receive LLDP)
CN 4093(config-if)# lldp admin-status tx_only (Only transmit LLDP)
CN 4093(config-if)# lldp admin-status rx_only (Only receive LLDP)
CN 4093(config-if)# no lldp admin-status
CN 4093(config-if)# exit
To view the LLDP transmit and receive status, use the following commands:
CN 4093(config)# show lldp port
CN 4093(config)# show interface port <n> lldp (status of selected port)
(Turn LLDP on or off globally)
(Select a switch port)
(Do not participate in LLDP)
(Exit port mode)
(status of all ports)
