E_Port Isolation

A Logged-In LED error indication is often the result of E_Port isolation. E_Port
isolation can be caused by the following:
Security failure
A port configured as FL_Port is connected to another switch
Conflicting domain IDs
Conflicting timeout values
Conflicting zone membership between active zone sets
Using QuickTools, review the event browser, and do the following to diagnose and
correct an isolated E_Port:
1. Does the event browser show an alarm about an invalid attach on the
affected port?
2. Does the event browser show a repeating alarm about an unsupported
E_Port command on the affected port?
3. Display the fabric domain IDs using the Show Domains command, or click
the Switch tab and Summary icon in QuickTools. Are all domain IDs in the
fabric unique?
