The status of this entry. The meanings of the values are: other(1) - none of the following. This may include the case where some other MIB object (not the corresponding instance of ieee8021QBridgeTpFdbPort, nor an entry in the ieee8021QBridgeStaticUnicastTable) is being used to determine if and how frames addressed to the value of the corresponding instance of ieee8021QBridgeTpFdbAddress are being forwarded. invalid(2) - this entry is no longer valid (e.g., it was learned but has since aged out), but has not yet been flushed from the table. learned(3) - the value of the corresponding instance of ieee8021QBridgeTpFdbPort was learned and is being used. self(4) - the value of the corresponding instance of ieee8021QBridgeTpFdbAddress represents one of the device's addresses. The corresponding instance of ieee8021QBridgeTpFdbPort indicates which of the device's ports has this address. mgmt(5) - the value of the corresponding instance of ieee8021QBridgeTpFdbAddress is also the value of an existing instance of ieee8021QBridgeStaticUnicastAddress.
