Troubleshooting Steps and

Action

 

Command

 

 

 

 

1

Execute the show axrp command to

Go to No. 3 if "enable" is displayed on "Oper State."

 

check the Ring Protocol operation state.

If "-" is displayed on "Oper State," the setting necessary for operating Ring Protocol

 

 

 

 

is not set in the configuration.

 

 

Check the configuration.

 

 

 

 

 

If "disable" is displayed on "Oper State," Ring Protocol is disabled. Check the

 

 

configuration.

 

 

 

 

 

If "Not Operating" is displayed on "Oper State," Ring Protocol is inoperative.

 

 

Check to see if any inconsistency (such as combination of operation mode, attribute

 

 

and ring port of the system is invalid) exists in configuration. Go to No. 2 if

 

 

configuration is valid. [IP8800/S6700] [IP8800/S6600] [IP8800/S6300]
