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 or the Switch data tab in the McDATA Embedded Web Server 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 McDATA Embedded Web Server Switch Properties window. Reset the port. If the condition remains, continue.
4.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 McDATA Embedded Web Server 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 McDATA Embedded Web Server Switch Properties dialog. Reset the port. If the condition remains, continue.
5.Display the active zone set on each switch using the Zoning Active command or the Active Zoneset tab of the McDATA Embedded Web Server topology display. Compare the zone membership between the two active zone sets. Are they the same?
•Yes - Contact your authorized maintenance provider.
•No - Deactivate one of the active zone sets or edit the conflicting zones so that their membership is the same. Reset the port. If the condition remains, contact your authorized maintenance provider.
NOTE: This can be caused by merging two fabrics whose active zone sets have two zones with the same name, but different membership.
