Field

Description

 

 

 

 

Bridge Maximum

Configurable field; the maximum permissible age, in

Age

seconds, provided by the current root bridge for

 

Spanning Tree configuration information to remain

 

active on the selected bridge.

 

When the time-span expires and the bridge has not

 

received any BPDUs, it discards the current Spanning

 

Tree information and initiates a new round of Span-

 

ning Tree configuration.

 

The recommended IEEE 802.1d time is 20s (twenty

 

seconds).

 

 

 

Bridge Hello Time

Configurable field; the amount of time, in seconds,

 

provided by the current root bridge between trans-

 

missions of configuration BPDUs. This timer works

 

with the Spanning Tree Hold Time, which should be

 

greater than the Hello Time.

 

If it is smaller, the Spanning Tree algorithm responds

 

more quickly to configuration changes, resulting in

 

increased network traffic.

 

The recommended IEEE 802.1d time is 2s (two sec-

 

onds).

 

 

 

Bridge Forward

Configurable field; the delay time, in seconds, pro-

Delay

vided by the current root bridge before a bridge starts

 

forwarding data packets.

 

The recommended IEEE 802.1d time is 15s (15 sec-

 

onds).

 

 

 

Time Since Topol-

Read-only field; displays the length of time since the

ogy Change

topology was changed.

 

 

 

Number Topology

Read-only field; displays the number of topology

Changes

changes that have occurred.
