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:
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]] [,...]}]
Example
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.

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.
