Description:
dot1dStpBridgeMaxAge: From RFC1493(Bridge MIB). The value that all bridges use for MaxAge when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of dot1dStpBridgeHelloTime. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds.
What is snVLanByPortStpGroupMaxAge?
This object controls the MaxAge timer parameter for Spanning Tree Protocol (STP) on a VLAN-by-port basis in a Foundry switch. MaxAge specifies how long a switch waits before discarding old BPDU information when it is acting as the root bridge. An operator would adjust this to tune loop detection behavior and convergence speed in bridged networks, balancing between quick failure detection and stability.
