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
