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

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.
