Configure a Network Control Policy

To permit the discovery of non-Cisco devices, FXOS supports the Link Layer Discovery Protocol (LLDP), a vendor-neutral device discovery protocol that is defined in the IEEE 802.1ab standard. LLDP allows network devices to advertise information about themselves to other devices on the network. This protocol runs over the data-link layer, which allows two systems running different network layer protocols to learn about each other.

Note

Cisco Discovery Protocol (CDP) is not supported on FXOS platforms. Although some CDP commands and show commands may appear in the FXOS CLI, they do not provide functional CDP capabilities and should not be used for device discovery or neighbor information.

LLDP is a one-way protocol that transmits information about the capabilities and current status of a device and its interfaces. LLDP devices use the protocol to solicit information only from other LLDP devices.

To enable this functionality on your FXOS chassis, you can configure a network control policy, which specifies LLDP transmission and receiving behavior. Once a network control policy is created, it needs to be assigned to an interface. You can enable LLDP on any front interface, including fixed ports, EPM ports, port channels, and break out ports.

Note

  • LLDP is not configurable on dedicated management ports.

  • Internal backplane ports that connect to the blade have LLDP enabled by default, with no option to disable. All other ports have LLDP disabled by default.
