Configuring LLDP
9
Use the [no] form of the command to disable the receive only mode.
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.
FastIron(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’s 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.
FastIron(config)#no lldp enable receive ports e 2/7 e 2/8
FastIron(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.
Syntax: [no] lldp enable transmit ports ethernet <slotnum/portnum> | all
Use the [no] form of the command to disable the transmit only mode.
Use the [no] form of the command to disable the receive only mode.
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.
Specifying the maximum number of LLDP neighbors
You can change the limit of the number of LLDP neighbors for which LLDP data will be retained, per
device as well as per port.
Per device
You can change the maximum number of neighbors for which LLDP data will be retained for the
entire system.
For example, to change the maximum number of LLDP neighbors for the entire device to 26, enter
the following command.
FastIron(config)#lldp max-total-neighbors 26
Syntax: [no] lldp max-total-neighbors <value>
Use the [no] form of the command to remove the static configuration and revert to the default
value of 392.
