LLDP-MED attributes advertised by the Brocade device
8
• 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.
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 2/4 to 2/12
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.
Brocade(config)#lldp advertise med-capabilities ports e 2/4 to 2/12
The LLDP-MED capabilities 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).
