Configuring LLDP

Untagged VLAN ID
The port VLAN ID TLV advertises the Port VLAN Identifier (PVID) that will be associated with
untagged or priority-tagged frames. If the port is not an untagged member of any VLAN (i.e., the
port is strictly a tagged port), the value zero will indicate that.
By default, the port VLAN ID is automatically advertised when LLDP is enabled on a global basis. To
disable this advertisement, enter a command such as the following.
BigIron RX(config)# no lldp advertise port-vlan-id ports e 2/4 to 2/12
The untagged VLAN ID will appear similar to the following on the remote device, and in the CLI
display output on the Brocade device (show lldp local-info).
Port VLAN ID: 99
Syntax: [no] lldp advertise port-vlan-id ports ethernet <slotnum/portnum> | all
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. Note that using the keyword all may cause undesirable
effects on some ports. For example, if you configure all ports to advertise their VLAN name, and
the configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN ports. The configuration will be applied to all ports,
however, the ports that are not members of any VLAN will not send VLAN name advertisements.
Protocol Identity
The protocol ID TLV indicates the availability of certain protocols on a port (for example, STP, RSTP,
MSTP, etc.).
802.3 capabilities
Except for Power-via-MDI information, the Brocade device will advertise the following 802.3
attributes when LLDP is enabled on a global basis:
• Link aggregation information
• MAC/PHY configuration and status
• Maximum frame size
Link aggregation
This section needs work
The link-aggregation TLV indicates the following:
• Whether the link is capable of being aggregated
• Whether the link is currently aggregated
• The primary trunk port
Brocade devices advertise link aggregation information about standard link aggregation (LACP) as
well as static trunk configuration.
By default, link-aggregation information is automatically advertised when LLDP is enabled on a
global basis. To disable this advertisement, enter a command such as the following.
BigIron RX(config)# no lldp advertise link-aggregation ports e 2/12
