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

		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]
