Syntax: [no] lldp enabletransmit 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).
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.
Specifying the maximum number of LLDP neighbors 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.
device(config)#lldp max-total-neighbors 26
Syntax: [no] lldp max-total-neighbors value
