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.
device(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 port-list | all
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
• Power-via-MDI information (not automatically advertised)
Link aggregation TLV
The link-aggregation time, length, value (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.
device(config)#no lldp advertise link-aggregation ports e 2/12
Syntax: [no] lldp advertise link-aggregation ports ethernet port-list | all
The link aggregation advertisement will appear similar to the following on the remote device, and in the
CLI display output on the Brocade device (show lldp local-info ).
Link aggregation: not capable
MAC and PHY configuration status
The MAC and PHY configuration and status TLV includes the following information:
• Auto-negotiation capability and status
• Speed and duplex mode
• Flow control capabilities for auto-negotiation
