Resolving an Isolated ISL Using Fabric Manager

Trunking E ports (TE ports) are similar to E ports except that they carry traffic for multiple VSANs. E
ports carry traffic for a single VSAN. Because TE ports carry traffic for multiple VSANs, ISL isolation
can affect one or more VSANs. For this reason, on a TE port you must troubleshoot for ISL isolation on
each VSAN.
To resolve VSAN isolation on a TE port using Fabric Manager, follow these steps:
Choose Switches > Interfaces > FC Physical and check the FailureCause column on the TE port to
Step 1
verify that you have a trunk problem.
Choose Switches > Interfaces > FC Physical and select the Trunk Failures tab to determine the reason
Step 2
for the trunk problem.
Correct the problem listed in the FailureCause column. See the
Step 3
Activating" section on page 11-14
Interfaces > FC Physical and use the PortVSAN field to correct the VSAN misconfiguration problems.
Repeat this procedure for all isolated VSANs on this TE port.
Step 4

Resolving an Isolated ISL Using the CLI

Trunking E ports (TE ports) are similar to E ports except that they carry traffic for multiple VSANs. E
ports carry traffic for a single VSAN. Because TE ports carry traffic for multiple VSANs, ISL isolation
can affect one or more VSANs. For this reason, on a TE port you must troubleshoot for ISL isolation on
each VSAN.
To resolve VSAN isolation on a TE port using the CLI, follow these steps:
Use the show interface command on the TE port to verify that you have an isolated VSAN.
Step 1
switch# show interface fc2/14
fc2/14 is trunking
The example shows the output of the show interface command with one or more isolated VSANs. Here,
the TE port has one VSAN isolated.
