Professional edition login troubleshooting

The following section states a possible issue and the recommended solution for Professional

edition login errors.

Problem Resolution

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.

Re-assign the threshold to the fabric. For step-by-step instructions, refer to “Assigning

thresholds” on page 693.

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.

Right-click on the fabric that the segmented switch (with red minus icon) is part of and

select Accept Changes.
