Viewing Fabric Attach Discovered Elements

Use this procedure to view Fabric Attach discovered elements.

About this task

When FA is enabled on an FA Server switch, LLDP PDUs are exchanged between the FA Server and FA Clients or FA Proxies. Standard LLDPs allow neighbors to be learned. With the help of organizational-specific element discovery TLVs, the client or proxy recognizes that it has attached to the FA Server. Only after the discovery handshake is complete, an FA Client or FA Proxy can transmit I-SID-to-VLAN assignments to join the SPB Fabric network through the FA Server.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display FA discovered elements:

    show fa elements

  3. Display FA discovered elements on a specific port:

    show fa elements [{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}]

Example

The following example displays the sample output for the show fa elements command.
Switch:1>show fa elements

Variable definitions

The following table defines parameters for the show fa elements command.

Variable

Value

{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

Identifies the slot and port in one of the following formats:

  • a single slot and port (slot/port)

  • a range of slots and ports (slot/port-slot/port)

  • a series of slots and ports (slot/port,slot/port,slot/port)

  • all ports on the same slot (slot/all)

  • all ports on the switch (all)

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
