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.
device(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.
device(config)#no lldp enable transmit ports e 2/7 e 2/8 e 2/9
device(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
.
Syntax:[no] lldp enable receive ports ethernet port-list | all
Use the [no] form of the command to disable the receive only mode.
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.
device(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.
device(config)#no lldp enable receive ports e 2/7 e 2/8
device(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
