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
FL_Port is connected to another switch
Conflicting domain IDs
Conflicting timeout values
Conflicting zone membership between active zone sets
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?
Yes - 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. 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.
