Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

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 auto-configure 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)

Notes: Network policy is only advertised for ports that are configured as members of the voice VLAN. If the port belongs to more than one voice VLAN, then 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, refer to “Network Policy Advertisements” on page 13-61

location_id

This TLV enables the switch port to advertise its configured location data (if any). For more on configuring location data, refer to “Configuring Location Data for LLDP-MED Devices”.

(Default: Enabled)

Note: When disabled, this TLV cannot be enabled unless the capability TLV is already enabled.

Configuring Location Data for LLDP-MED Devices

You can configure a switch port to advertise location data for the switch itself, the physical wall-jack location of the endpoint (recommended), or the location of a DHCP server supporting the switch and/or endpoint. You also have the option of configuring these different address types:

■civic address: physical address data such as city, street number, and building information

■ELIN (Emergency Location Identification Number): an emergency number typically assigned to MLTS (Multiline Telephone System Opera- tors) in North America

■coordinate-based location: attitude, longitude, and altitude informa- tion (Requires configuration via an SNMP application.)
