Bridge MIB

and all others would start using if/when this bridge were to become
the root.

dot1dStpBridgeMaxAge

{dot1dStp 12}

Time Ticks Read-Write

The value that all bridges use for MaxAge when this bridge is
acting as the root. Note that 802.1d/D9 specifies that the range for
this parameter is related to the value of dot1dStpBridgeHelloTime.
The granularity of this timer is specified by 802.1d/D9 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.

The Max Age Time must be at least 6 seconds, and must adhere to
the following equations involving Max Age Time, Forward Delay
Time, and Hello Time:

2 x (Forward Delay Time - 1) >= Max Age Time

Max Age >= 2 x (Hello Time + 1)

dot1dStpBridgeHelloTime

{dot1dStp 13}

Time Ticks Read-Write

The value that all bridges use for HelloTime when this bridge is
acting as the root. The granularity of this timer is specified by
802.1d/D9 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.

The Hello Time must adhere to the equation described in the
variable dot1dStpBridgeMaxAge, involving Max Age Time and
Hello Time.

dot1dStpBridgeForwardDelay

{dot1dStp 14}

Time Ticks Read-Write

The value that all bridges use for ForwardDelay when this bridge
is acting as the root. Note that 802.1d/D9 specifies that the range
for this parameter is related to the value of
dot1dStpBridgeMaxAge. The granularity of this timer is specified
