a3ComBrgFwTblSize
Module: A3COM-BRIDGE-R3-MIB
OID (symbolic): A3COM-BRIDGE-R3-MIB::a3ComBrgFwTblSize
OID (numeric): 1.3.6.1.4.1.43.2.9.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object returns the size of the bridge forwarding table in units of 2^(9+n) where n is the value of this object. Thus, if this object has the value 2, then the bridge forwarding table has 2048 entries.
If this value is changed, via a set, the new value will take affect only after the bridging service is disabled and re-enabled.
What is a3ComBrgFwTblSize?
This read-write integer (1-64) specifies the forwarding table capacity in units of 2^(9+n) MAC address entries, allowing tuning for network size. A value of 2 creates a 2048-entry table; increasing this value reserves more memory for MAC learning in large networks. Changing this value requires disabling and re-enabling the bridging service, so it's set during commissioning or during scheduled maintenance.
