Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

Notes A codepoint must have an 802.1p priority before you can configure it for use

in prioritizing packets by VLAN-ID. If a codepoint you want to use shows No

Override in the Priority column of the DSCP policy table (display with show qos-

dscp map, then use qos-dscp map < codepoint > priority < 0 - 7 > to configure a

priority before proceeding. For more on this topic, refer to the chapter titled

“Quality of Service (QoS): Managing Bandwidth More Effectively” in the

Advanced Traffic Management Guide for your switch.

Enabling or Disabling medTlvEnable. In the default LLDP-MED

configuration, the TLVs controlled by medTlvEnable are enabled.

Syntax: [ no ] lldp config < port-list > medTlvEnable < medTlv >

■ Enables or disables advertisement of the following TLVs

on the specified ports:

• device capability TLV

• configured network policy TLV

• configured location data TLV (Refer to “Configuring

Location Data for LLDP-MED Devices” on page

14-65.)

• current PoE status TLV

(Default: All of the above TLVs are enabled.)

■ Helps to locate configuration mismatches by allowing use

of an SNMP application to compare the LLDP-MED con-

figuration on a port with the LLDP-MED TLVs advertised

by a neighbor connected to that port.

capabilities

This TLV enables the switch to determine:

• which LLDP-MED TLVs a connected endpoint can

discover

• the device class (1, 2, or 3) for the connected

endpoint

This TLV also enables an LLDP-MED endpoint to

discover what LLDP-MED TLVs the switch port cur-

rently supports.

(Default: enabled)

Note: This TLV cannot be disabled unless the

network_policy, poe, and location_id TLVs are already

disabled.
