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 SANbox Manager topology display. E_Port
isolation can be caused by a security failure, conflicting domain IDs, conflicting
timeout values, or conflicting zone membership between active zone sets. Refer
to the SANbox2-8c/16 Switch Management User's 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 alarm for an invalid attach for the affected
port?
2. 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?
3. Compare the RA_TOV and ED_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?
4. Display the active zone set on each switch using the Zoning Active
command or the Active Zoneset tab of the SANbox Manager topology
display. Compare the zone membership between the two active zone sets.
Are they the same?

so that their membership is the same. Reset the port. If the condition
remains, contact your authorized maintenance provider.
