Brocade Communications Systems 6650 manual LLDP-MED attributes advertised by the Brocade device

LLDP-MED attributes advertised by the Brocade device 8

•priority <0 –7> indicates the Layer 2 priority value to be used for the specified application type. Enter 0 to use the default priority.

•dscp <0 – 63> specifies the Layer 3 Differentiated Service codepoint priority value to be used for the specified application type. Enter 0 to use the default priority.

Specify the ethernet port in the <stack-unit>/<slot>/<port>format. Stack-unit is 1.

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.

LLDP-MED attributes advertised by the Brocade device

LLDP-MED attributes are only advertised on a port if LLDP-MED is enabled (which is done by enabling the LLDP-MED capabilities TLV), the port operating mode is receive and transmit (the default), and the port has received an LLDP-MED advertisement from an Endpoint. By default, the Brocade device will automatically advertise the following LLDP-MED attributes when the above criteria are met:

•LLDP-MED capabilities

•Location ID

•Network policy

•Power-via-MDI information

NOTE

Although the Location ID and Network policy attributes are automatically advertised, they will have no effect until they are actually defined.

LLDP-MED capabilities

When enabled, LLDP-MED is enabled, and the LLDP-MED capabilities TLV is sent whenever any other LLDP-MED TLV is sent. When disabled, LLDP-MED is disabled and no LLDP-MED TLVs are sent.

The LLDP-MED capabilities advertisement includes the following information:

•The supported LLDP-MED TLVs

•The device type (Network Connectivity device or Endpoint (Class 1, 2, or 3))

By default, LLDP-MED information is automatically advertised when LLDP-MED is enabled. To disable this advertisement, enter a command such as the following.

Brocade(config)#no lldp advertise med-capabilities ports e 1/1/1 to 1/1/5

NOTE

Disabling the LLDP-MED capabilities TLV disables LLDP-MED.

To re-enable the LLDP-MED Capabilities TLV (and LLDP-MED) after it has been disabled, enter a command such as the following.
