Configuring LLDP
20
PowerConnect(config)#no lldp enable transmit ports e 7 e 8 e 9
PowerConnect(config)#lldp enable receive ports e 7 e 8 e 9
The above commands change the LLDP operating mode on ports 7, 8, and 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.
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 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.
PowerConnect(config)#no lldp enable receive ports e 4 e 5 e 6
The above command changes the LLDP operating mode on ports 4, 5, and 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.
PowerConnect(config)#no lldp enable receive ports e 7 e 8
PowerConnect(config)#lldp enable transmit ports e 7 e 8
The above commands change the LLDP operating mode on ports 7 and 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 <port-list> | all
Use the [no] form of the command to disable the transmit only mode.
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.
