Port Fencing troubleshooting

The following section states a possible issue and the recommended solution for Port Fencing
errors.
Problem
In a pure M-EOS fabric, fabric level policy
information (for example, Port Fencing Link
threshold) is stored in database based on the
principle switch WWN. Therefore, if you add a
switch to the fabric and the new switch becomes
the Principle switch, the Management
application cannot obtain the policy information
and the threshold is not applied.
If you segment a switch from a fabric then
rediscover the switch without accepting
changes, the Port Fencing dialog box displays
the switch twice and the port count is doubled.

Resolution
Re-assign the threshold to the fabric. For step-by-step instructions, refer to
thresholds"
on page 339.
Right-click on the fabric that the segmented switch (with red minus icon) is part of and
select Accept Changes.
