Configuring LLDP

Enabling support for tagged LLDP packets

By default, Dell PowerConnect devices do not accept tagged LLDP packets from other vendors'
devices. To enable support, apply the command lldp tagged-packets process at the Global CONFIG
level of the CLI. When enabled, the device will accept incoming LLDP tagged packets if the VLAN
tag matches any of the following:
•
•
•
To enable support for tagged LLDP packets, enter the following command.
PowerConnect(config)#lldp tagged-packets process
Syntax: [no] lldp tagged-packets process

Changing a port LLDP operating mode

LLDP packets are not exchanged until LLDP is enabled on a global basis. When LLDP is enabled on
a global basis, by default, each port on the Dell device will be capable of transmitting and receiving
LLDP packets. You can disable a port's ability to transmit and receive LLDP packets, or change the
operating mode to one of the following:
•
•
You can configure a different operating mode for each port on the Dell PowerConnect device. For
example, you could disable the receipt and transmission of LLDP packets on port e 2/1, configure
port e 2/3 to only receive LLDP packets, and configure port e 2/5 to only transmit LLDP packets.
The following sections show how to change the operating mode.
Enabling and disabling receive and transmit mode
To disable the receipt and transmission of LLDP packets on individual ports, enter a command
such as the following at the Global CONFIG level of the CLI.
PowerConnect(config)#no lldp enable ports e 2/4 e 2/5
The above command disables LLDP on ports 2/4 and 2/5. These ports will not transmit nor
receive LLDP packets.
To enable LLDP on a port after it has been disabled, enter the following command.
PowerConnect(config)#lldp enable ports e 2/4
Syntax: [no] lldp enable ports ethernet <port-list> | all
Use the [no] form of the command to disable the receipt and transmission of LLDP packets on a
port.
For <port-list>, specify the ports in the following formats:
•
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.
