If a Port Status LED shows an error indication, review the alarm log for messages 
regarding the affected port. You can inspect the alarm log using the Alarm data 
tab in SANbox Manager faceplate display or the Show Alarm command. Pertinent 
alarm log messages will point to one or more of the following conditions:

■

E_Port isolation

■

Excessive port errors

A Port Status LED error indication is often the result of E_Port isolation. An 
isolated E_Port is indicated by a red link in the SANbox Manager topology display. 
E_Port isolation can be caused by conflicting domain IDs, conflicting timeout 
values, or conflicting zone membership between active zone sets. Refer to the 
SANbox2-64 Switch Management User’s Guide for information about how to 
change domain IDs, timeout values, and edit zoning.

Review the alarm log and do the following to diagnose and correct an isolated 
E_Port:

1.

Display the fabric domain IDs using the Show Domains command or the 
Switch data tab in the SANbox Manager 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 SANbox Manager Switch Properties 
window. Reset the port. If the condition remains, continue.

2.

Compare the RA_TOV, ED_TOV, RT_TOV timeout values for all switches in 
the fabric using the Show Config Switch command or the Switch data tab of 
the SANbox Manager topology display. Is each timeout value the same on 
every switch?

■

Yes - Continue.

■

No - Correct the timeout values on the offending switches using the 
Set Config Switch command or the SANbox Manager Switch 
Properties window. Reset the port. If the condition remains, continue.
