Configuring LLDP
The system name will appear similar to the following on the remote device, and in the CLI display
output on the Brocade device (show lldp local-info).
Syntax: [no] lldp advertise system-name 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.
802.1 capabilities
Except for the VLAN name, the Brocade device will advertise the following 802.1 attributes when
LLDP is enabled on a global basis:
•
•
VLAN name
The VLAN name TLV contains the name and VLAN ID of a VLAN configured on a port. An LLDPDU
may include multiple instances of this TLV, each for a different VLAN.
To advertise the VLAN name, enter a command such as the following.
BigIron RX(config)#lldp advertise vlan-name vlan 99 ports e 2/4 to 2/12
The VLAN name will appear similar to the following on the remote device, and in the CLI display
output on the Brocade device (show lldp local-info).
Syntax: [no] lldp advertise vlan-name vlan <vlan ID> ports ethernet <slotnum/portnum> | all
For <vlan ID>, enter the VLAN ID to advertise.
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.
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.
Brocade's implementation of the port and protocol VLAN ID feature differs from the IEEE 802.1Q
standard. Therefore, the following command is used:
270
System name: "BigIron RX"
VLAN name (not automatically advertised)
Untagged VLAN ID
VLAN name (VLAN 99): "Voice-VLAN-99"
