Enabling support for tagged LLDP packets

By default, Brocade 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:

• a configured VLAN on the port
• the default VLAN for a tagged port
• the configured untagged VLAN for a dual-mode port

To enable support for tagged LLDP packets, enter the following command.

device(config)#lldp tagged-packets process

Syntax: [no] lldptagged-packets process

Changing a port LLDP operating 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. You can disable a port’s ability to transmit and receive LLDP
packets, or change the operating mode to one of the following:

• Transmit LLDP information only
• Receive LLDP information only

You can configure a different operating mode for each port on the Brocade 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.

device(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.

device(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.

NOTE
When a port is configured to both receive and transmit LLDP packets and the MED capabilities TLV is
enabled, LLDP-MED is enabled as well. LLDP-MED is not enabled if the operating mode is set to
receive only or transmit only.
