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 13-76. Port VLAN ID TLV Support on LLDP The port-vlan-id option enables advertisement of the port VLAN ID TLV as part of the regularly advertised TLVs. This allows discovery of a mismatch in the configured native VLAN ID between LLDP peers. The information is visible using show commands and will be logged to the Syslog server. Configuring the VLAN ID TLV This TLV advertisement is enabled by default. To enable or disable the TLV, use this command. Syntax: [no] lldp config dot1TlvEnable port-vlan-id Enables the VLAN ID TLV advertisement. The no form of the command disables the TLV advertisement. Default: Enabled.
