LLDP configuration

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 200.

Syntax: [no] lldp enable transmit ports ethernet port-list | all

Use the [no] form of the command to disable the transmit only mode.

Configuring LLDP processing on 802.1x blocked port

This feature adds support for reception and transmission of Link Layer Discovery Protocol (LLDP)

packets over an 802.1x blocked port. The default behavior is to drop received LLDP packets and

not to transmit LLDP packets over an 802.1x disabled port. To receive or transmit LLDP packets

over 802.1x blocked port or in other words to enable the LLDP processing on 802.1x blocked ports,

use the lldp-pass-through configuration command.

Enabling LLDP processing on 802.1x blocked port

To enable the LLDP processing on all 802.1x blocked ports, enter the following command at the

802.1X configuration mode:

Brocade(config-dot1x)# lldp-pass-through all

Syntax: [no] lldp-pass-through all

To enable LLDP processing on a specific 802.1x blocked port, enter the following command at the

802.1X configuration mode:

Brocade(config-dot1x)# lldp-pass-through ethernet 1/1/1

Syntax: [no] lldp-pass-through ethernet port

Specify the port variable in the format stackable switches-stack-unit/slotnum/portnum

The no form of these commands disables LLDP processing on 802.1x blocked ports.

For more information on LLDP and 801.1x, refer IEEE 802.1AB and IEEE 802.1x.

NOTE

If lldp-pass-through is disabled, the neighboring information is lost only after LLDP timeout period

(default is 120).
