Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Syntax:
[ no ] lldp config <
port-list
> dot3TlvEnable macphy_config
For outbound advertisements, this TLV includes the
(local) switch port’s current speed and duplex settings, the
range of speed and duplex settings the port supports, and
the method required for reconfiguring the speed and
duplex settings on the device (auto-negotiation during
link initialization, or manual configuration).
Using SNMP to compare local and remote information can
help in locating configuration mismatches.
(Default: Enabled)
Note:
For LLDP operation, this TLV is optional. For
LLDP-MED operation, this TLV is mandatory.
As mentioned above, an SNMP network management application can be used
to compare the port speed and duplex data configured in the switch and
advertised by the LLDP endpoint. You can also use the CLI to display this
information. For more on using the CLI to display port speed and duplex
information, refer to “Displaying the Current Port Speed and Duplex
Configuration on a Switch Port” on page 13-69.
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
