enable lldp ports

enable lldp ports [all | port_list] {receive-only | transmit-only}


Enables LLDP (Link Layer Discovery Protocol) transmit mode, receive mode, or transmit and receive mode. If the transmit-only or receive-only option is not specified, both transmit and receive modes are enabled.

Syntax Description

all Specifies all ports on the switch.
port_list Specifies one or more ports or slots and ports.
receive-only Specifies that the port only receives LLDP messages.
transmit-only Specifies that the port only transmits LLDP messages.



Usage Guidelines

If you do not specify an option, the port is enabled to both transmit and receive LLDP messages.

Once the port is enabled for LLDP in one mode and you issue another enable lldp ports command for another mode, that second mode replaces the original mode. For example, you might originally enable several ports to only receive LLDP messages and then want those ports to both receive and transmit LLDP messages. In that case, you issue the enable lldp ports command with no variables (and the receive-and-transmit mode replaces the receive-only mode).

To verify the port setting for LLDP, use the show lldp {port [all |port_list]} {detailed} command.


The following example enables LLDP transmit and receive mode on port 1:4.

enable lldp port 1:4
