Before configuring this object with (forceSwitch) or (manualSwitch), fsErpsRingConfigSwitchPort must be configured. When ForcedSwitch is enabled on a ring, irrespective of the status (Failed or not failed) of the switched port, port will be blocked. If a link failure is present in the ring, then setting the value as 'manualSwitch' will not be allowed. Failure of the link in the ring will clear the Manual Switch condition. Force Switch is of higher priority than the Manual switch. Force switch will overwrite the manual switch configuration. Similarly manual switch will not be allowed, when force switch is enabled. When this object is set to forceSwitch: - forceswitch will be applied for this ring. - port identified in fsErpsRingConfigSwitchPort object will be blocked. Setting of this object to manualswitch value will fail if: - forceswitch is already set or - local SF is present in any of the ring port or - R-APS(SF) is present in the priority logic for this ring. When this object is set to manualSwitch: - Port identified in fsErpsRingConfigSwitchPort object will be blocked. ManualSwitch will be automatically cleared if: - local-SF is received on one of the ring ports - R-APS(SF) is received on the ring port (none) command will clear the Manual/Force Switch, and the ring will work in the normal mode. The value of (none) is applicable to clear the manual/force switch only when the compatible version is 1.
