ieee8021SpanningTreeBridgeMaxAge
Module: IEEE8021-SPANNING-TREE-MIB
OID (symbolic): IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeBridgeMaxAge
OID (numeric): 1.3.111.2.802.1.1.3.1.1.1.13
Node type: OBJECT-TYPE
Type: Timeout
Access: read-write
Description: The value that all Bridges use for MaxAge when this Bridge is acting as the root. Note that IEEE Std 802.1D-1998 specifies that the range for this parameter is related to the value of ieee8021SpanningTreeBridgeHelloTime. The granularity of this timer is specified by IEEE Std 802.1D-1998 to be 1 second. An agent may return an SNMP badValue error (or its equivalent if another protocol is used) if a set is attempted to a value that is not a whole number of seconds.
The value of this object MUST be retained across reinitializations of the management system.
What is ieee8021SpanningTreeBridgeMaxAge?
The MaxAge value this bridge would advertise to the whole network if it became the root bridge; settable in the 6-40 second range, and must be retained across reboots since it defines network-wide STP timing when this switch wins root election.
