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 (see
Configuring location data for LLDP-MED devices
• 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
configuration 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 currently supports.(Default: enabled)
This TLV cannot be disabled unless the
network_policy
,
poe
, and
location_id
TLVs are already disabled.
network_policy
This TLV enables the switch port to advertise its configured network policies (voice
VLAN, Layer 2 QoS, Layer 3 QoS), and allows LLDP-MED endpoint devices to
autoconfigure the voice network policy advertised by the switch. This also enables
the use of SNMP applications to troubleshoot statically configured endpoint network
policy mismatches.(Default: Enabled)
Network policy is advertised only for ports that are configured as members of the
voice VLAN. If the port belongs to more than one voice VLAN, the voice VLAN with
the lowest-numbered VID is selected as the VLAN for voice traffic. Also, this TLV
cannot be enabled unless the
capability
TLV is already enabled.
For more information, see
on page 236.
location_id
This TLV enables the switch port to advertise its configured location data (if any). For
more information on configuring location data, see
on page 238.(Default: Enabled)
When disabled, this TLV cannot be enabled unless the capability TLV is already
enabled.
poe
This TLV enables the switch port to advertise its current PoE state and to read the
PoE requirements advertised by the LLDP-MED endpoint device connected to the
port.(Default: Enabled)
When disabled, this TLV cannot be enabled unless the
capability
TLV is already
enabled.
