LLDP configuration
Syntax: [no] lldp enable ports ethernet <port-list> | all
Use the [no] form of the command to disable the receipt and transmission of LLDP packets on a
port.
For port-list , specify the ports in one of the following formats:
• FWS, FCX and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• FESX compact switches – portnum
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually.
NOTE
When a port is configured to both receive and transmit LLDP packets and the MED capabilities TLV
is enabled, LLDP-MED is enabled as well. LLDP-MED is not enabled if the operating mode is set to
receive only or transmit only.
Enabling and disabling receive only mode
When LLDP is enabled on a global basis, by default, each port on the Brocade device will be
capable of transmitting and receiving LLDP packets. To change the LLDP operating mode from
receive and transmit mode to receive only mode, simply disable the transmit mode. Enter a
command such as the following at the Global CONFIG level of the CLI.
Brocade(config)#no lldp enable transmit ports e 2/4 e 2/5 e 2/6
The above command changes the LLDP operating mode on ports 2/4, 2/5, and 2/6 from transmit
and receive mode to receive only mode.
To change a port LLDP operating mode from transmit only to receive only, first disable the transmit
only mode, then enable the receive only mode. Enter commands such as the following.
Brocade(config)#no lldp enable transmit ports e 2/7 e 2/8 e 2/9
Brocade(config)#lldp enable receive ports e 2/7 e 2/8 e 2/9
The above commands change the LLDP operating mode on ports 2/7, 2/8, and 2/9, from transmit
only to receive only. Note that if you do not disable the transmit only mode, you will configure the
port to both transmit and receive LLDP packets.
NOTE
LLDP-MED is not enabled when you enable the receive only operating mode. To enable LLDP-MED,
you must configure the port to both receive and transmit LLDP packets. Refer to “Enabling and
disabling receive and transmit mode” on page 459.
