Display Switched UNI (ELAN) I-SID Information

Use this procedure to display information on FA-created Switched UNI (ELAN) I-SIDs.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display all Switched UNI (ELAN) I-SIDs:

    show i-sid elan

  3. Display ELAN I-SID information on an MLT:
    show mlt i-sid [<1–512>]
    Note

    Note

    Viewing ELAN I-SID information on an MLT is useful to understand the origin of the I-SID when multiple client or proxy devices connecting to the FA Server using SMLT MLT advertise the same I-SID-to-VLAN mappings. In the event of a link failure on an MLT, the origin of the I-SID helps determine on which MLT, and thereby from which proxy or client device, the mappings were successfully learnt.

  4. Display ELAN I-SID information on ports:

    show interfaces gigabitEthernet i-sid [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Examples

Display information on all Switched UNI (ELAN) I-SIDs.

The following sample output displays, for example, the I-SID information on one of the peer switches of the FA Server, in a dual-homed SMLT configuration.

Switch:1>enable

Note

Note

The I-SID TYPE field displays once for each I-SID. The I-SID TYPE of an I-SID that is either learned through FA mapping assignments or configured as an FA management I-SID, is always ELAN. If a platform VLAN has the same I-SID value as that of the I-SID in an FA mapping assignment or in an FA management I-SID configuration, then the platform VLAN is associated with the I-SID endpoint and appears in the VLANID column. 

Display MLT I-SID information for MLT 1.

Variable Definitions

The following table defines parameters for the show i-sid command.

Variable

Value

elan

Displays all ELAN I-SIDs.

The following table defines parameters for the show mlt i-sid command.

Variable

Value

<1–512>

The valid range for MLT ID.

The following table defines parameters for the show interfaces gigabitEthernet i-sid command.

Variable

Value

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

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), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
