E_Port Isolation
A Logged-In LED error indication is often the result of E_Port isolation. An isolated
E_Port is indicated by a red link in the Enterprise Fabric Suite 2007 topology
display. 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
Refer to the SANbox 9000 Series Enterprise Fabric Suite 2007 User Guide or the
SANbox 9000 Series Stackable Chassis Switch Command Line Interface Guide
for information about how to change domain IDs, timeout values, and edit zoning.
Review the event browser and do the following to diagnose and correct an
isolated E_Port:
1. Does the event browser show an invalid attach alarm for 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 or the
Switch data tab in the Enterprise Fabric Suite 2007 topology display. 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 or the Enterprise Fabric Suite 2007 Switch
Properties window. Reset the port. If the condition remains, continue.
