[CAUSE] The tmnxSfmIcPortDegraded notification is generated when the system has detected a degradation of the switch fabric that is associated with a particular SFM interconnect port. The value of tmnxSfmIcPortDegradeState will reflect this condition by having a value that is NOT 'none (1)'. If the value of tmnxSfmIcPortDegradeState is 'degraded (2)' the SFM interconnect port can still carry some traffic but not at the full capacity of the port. The port and attached cable are not necessarily the cause of the degradation but are a likely cause. [EFFECT] Switch fabric capacity on this port is reduced when tmnxSfmIcPortDegradeState is degraded. This may not be causing any impact to service because of redundancy in the fabric. [RECOVERY] Although it may not be necessary to maintain full service, replacing the affected components may restore some fabric capacity.
