Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
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 12-45.
Displaying Advertisement Data
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.
