Port and Protocol VLAN ID
The port and protocol VLAN TLV indicates if a port is capable of supporting port and protocol VLANs
and whether it is enabled on the port. If port and protocol VLANs are enabled on the port, the
advertisement also contains the port and protocol VLAN ID (PPVID). If the port is not capable of
supporting port and protocol VLANs, or if the port is not enabled with any port and protocol VLAN,
the PPVID number will be zero.
Use the lldp advertise port-protocol-vlan-id ports ethernet command to enable or disable
advertising the port and protocol VLAN ID.
Brocade(config)#lldp advertise port-protocol-vlan-id ports e 2/4 to 2/12
The port and protocol VLAN ID 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):
Port-Protocol VLAN ID: not supported
Syntax: [no] lldp advertise port-protocol-vlan-id ports ethernet port list | all
For port list, specify the ports in the format [slotnum/]portnum, where slotnum is required on
chassis devices only. You can list all of the ports individually, use the keyword to to specify a range
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.
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 (that is, 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.
Brocade(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
For port list, specify the ports in the format [slotnum/]portnum, where slotnum is required on
chassis devices only. You can list all of the ports individually, use the keyword to to specify a range
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. The configuration
will be applied to all ports, however, the ports that are not members of any VLAN will not send VLAN
name advertisements.
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
