[CAUSE] The tmnxSysSwFabFailRecStarted notification is generated when the router has initiated an automatic switch fabric recovery process based on detecting frequent failures to multiple IOM/XCMs. Such multiple failures could be caused by issues on the SFM so this process involves the sequential reset of the SFMs to attempt to clear the cause of the failures. [EFFECT] The router shall operate at reduced switch fabric capacity while each individual SFM is reset in turn. [RECOVERY] This process will run until all the SFMs have been processed. No recovery is necessary.
