1.3.6.1.2.1.17.4.1.0 : dot1dTpLearnedEntryDiscards ; 0

"The total number of Forwarding Database entries that have been or would have been learned, but have been discarded due to a lack of storage space in the Forwarding Database. If this counter is increasing, it indicates that the Forwarding Database is regularly becoming full (a condition that has unpleasant performance effects on the subnetwork). If this counter has a significant value but is not presently increasing, it indicates that the problem has been occurring but is not persistent."

1.3.6.1.2.1.17.4.2.0 : dot1dTpAgingTime [범위 : 10 - 1000000] ; 300

"The timeout period in seconds for aging out dynamically-learned forwarding information. 802.1D-1998 recommends a default of 300 seconds."

OID : dot1dTpFdbAddress (1.3.6.1.2.1.17.4.3.1.1)

1.3.6.1.2.1.17.4.3.1 : dot1dTpFdbEntry

1.3.6.1.2.1.17.4.3.1.1 : dot1dTpFdbAddress ; 00-14-69-A7-1B-F8

"Information about a specific unicast MAC address for which the bridge has some forwarding and/or filtering information." 

1.3.6.1.2.1.17.4.3.1.2 : dot1dTpFdbPort ; 41

"Either the value '0', or the port number of the port on which a frame having a source address equal to the value of the corresponding instance of dot1dTpFdbAddress has been seen. A value of '0' indicates that the port number has not been learned, but that the bridge does have some forwarding/filtering information about this address (e.g., in the dot1dStaticTable(1.3.6.1.2.1.17.5)). Implementors are encouraged to assign the port value to this object whenever it is learned, even for addresses for which the corresponding value of dot1dTpFdbStatus is not learned(3)."

1.3.6.1.2.1.17.4.3.1.3 : 3 (learned)

"The status of this entry. The meanings of the values are:
other(1) - none of the following. This would include the case where some other MIB object (not the corresponding instance of
dot1dTpFdbPort, nor an entry in the dot1dStaticTable) is being used to determine if and how frames addressed to the value of the
corresponding instance of dot1dTpFdbAddress 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invalid(2) - this entry is no longer valid (e.g., it was learned but has since aged out), but has not yet been flushed from the table.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 dot1dTpFdbPort was learned, and is being used.
self(4) - the value of the corresponding instance of dot1dTpFdbAddress represents one of the bridge's addresses. The corresponding instance of dot1dTpFdbPort indicates which of the bridge's ports has this address.
mgmt(5) - the value of the corresponding instance of dot1dTpFdbAddress is also the value of an existing instance of dot1dStaticAddress."
