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 then 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?
Yes—If device security is configured, review the ISL group in the active
security set to ensure that the membership includes the necessary
ports, and that the secrets on all switches are correct.
No—Continue.
2. Does the event browser show a repeating alarm about an unsupported
E_Port command on the affected port?
Yes—The port is configured as an FL_Port and connected to another
switch. Correct the port connection or the port type.
No—Continue.
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?
Yes—Continue.
No—Correct the domain IDs on the offending switches using the Set
Config Switch command. Reset the port. If the condition remains,
continue.
