5.10.1 RSTP Configuration
„ „
System Priority: Sets„the„system„priority„of„each„switch„within„the„network.„The„
switch„with„the„lowest„system„priority„will„become„the„root„bridge.„If„the„switch„
is„used„in„a„large-scale„enterprise„network,„it„is„recommended„to„skip„this„setting.„
„ „
Hello Time: Sets„a„value„ranging„1„second„to„10„seconds.„This„sets„the„time„inter-
val„for„the„root„bridge„transmission„of„BPDU„packets„to„all„of„other„switches,„so„
it„is„known„which„switch„is„serving„as„the„root„bridge.„When„a„switch„not„serving„
as„the„root„bridge„is„set„with„a„specific„value,„the„value„does„not„take„effect.„Only„
when„the„switch„becomes„the„root„bridge„is„the„setting„active.„
„ „
Max Age: Sets„a„value„ranging„6„seconds„to„40„seconds.„If„a„switch„does„not„
receive„the„BPDU„packet„transmitted„by„the„root„bridge„when„the„maximum„
aging„time„is„up,„the„switch„will„take„over„as„the„root„bridge„and„transmit„the„
BPDU„packets„to„all„other„switches.„If„the„switch„has„the„lowest„priority„level,„it„
will„continue„to„function„as„the„root„bridge.„This„setting„should„be„set„to„a„large„
value,„to„avoid„unnecessary„resetting„of„the„root„bridge.„
„ „
Forward Delay: „Sets„a„value„ranging„4„seconds„to„30„seconds.„This„is„the„moni-
toring„time„for„a„switch„port„to„change„from„blocking„status„into„forwarding„
status„(i.e.„how„long„it„will„take„for„a„port„to„become„active„after„another„port„
has„failed).„A„higher„value„means„greater„delay„in„response.
„ „
Version: Selects„the„version„of„Spanning„Tree„to„use:„RSTP„based„on„802.1W„(de-
fault„value)„or„STP„based„on„802.1D„(Note:„RTSP„is„the„current„industry„standard.)
