Configuring LLDP
24
PowerConnect(config)#no lldp enable receive ports e 2/7 e 2/8
PowerConnect(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 694.
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 the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/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.
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.
PowerConnect(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.
where <value> is a number between 16 and 8192. The default number of LLDP neighbors per
device is 392.
Use the show lldp command to view the configuration.
Per port
You can change the maximum number of LLDP neighbors for which LLDP data will be retained for
each port. By default, the maximum number is four and you can change this to a value between
one and 64.
For example, to change the maximum number of LLDP neighbors to six, enter the following
command.
