Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) The port VLAN ID TLV local information can be obtained from the MIB object lldpXdot1LocPortVlanId in the local information table lldpXdot1LocTable. The port VLAN ID TLV information about all the connected peer devices can be obtained from the MIB object lldpXdot1RemPortVlanId in the remote information table lldpXdot1RemTable. LLDP-MED (Media-Endpoint-Discovery) LLDP-MED (ANSI/TIA-1057/D6) extends the LLDP (IEEE 802.1AB) industry standard to support advanced features on the network edge for Voice Over IP (VoIP) endpoint devices with specialized capabilities and LLDP-MED standards-based functionality. LLDP-MED in the switches uses the standard LLDP commands described earlier in this section, with some extensions, and also introduces new commands unique to LLDP-MED operation. The show commands described elsewhere in this section are applicable to both LLDP and LLDP-MED operation. LLDP-MED benefits include: ■ plug-and-play provisioning for MED-capable, VoIP endpoint devices ■ simplified, vendor-independent management enabling different IP telephony systems to interoperate on one network ■ automatic deployment of convergence network policies (voice VLANs, Layer 2/CoS priority, and Layer 3/QoS priority) ■ configurable endpoint location data to support the Emergency Call Service (ECS) (such as Enhanced 911 service, 999, 112) ■ detailed VoIP endpoint data inventory readable via SNMP from the switch ■ Power over Ethernet (PoE) status and troubleshooting support via SNMP ■ support for IP telephony network troubleshooting of call quality issues via SNMP This section describes how to configure and use LLDP-MED features in the switches to support VoIP network edge devices (Media Endpoint Devices) such as: ■ IP phones ■ voice/media gateways ■ media servers 13-62
