LLDP configuration
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.
Enabling and Disabling Transmit 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 to
transmit only mode, simply disable the receive mode. Enter a command such as the following at
the Global CONFIG level of the CLI.
Brocade(config)#no lldp enable receive 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 transmit only mode. Any incoming LLDP packets will be dropped in software.
To change a port LLDP operating mode from receive only to transmit only, first disable the receive
only mode, then enable the transmit only mode. For example, enter commands such as the
following at the Global CONFIG level of the CLI.
Brocade(config)#no lldp enable receive ports e 2/7 e 2/8
Brocade(config)#lldp enable transmit ports e 2/7 e 2/8
The above commands change the LLDP operating mode on ports 2/7 and 2/8 from receive only
mode to transmit only mode. Any incoming LLDP packets will be dropped in software. Note that if
you do not disable receive only mode, you will configure the port to both receive and transmit LLDP
packets.
NOTE
LLDP-MED is not enabled when you enable the transmit 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.
Syntax: [no] lldp enable transmit ports ethernet <port-list> | all
Use the [no] form of the command to disable the transmit only mode.
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.
