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
