hi every body!
I have few question:
1)Should the timer setting such as hello time, max-age time, etc be configured on root bridge or they can be configured independenly on each switch in rstp network ?
2) Can two switches have different hello time or max time in rstp?
3)A mulilayer switch store security acl and qos acl in tcam . My question is are they put in different tcams i.e secuirty acl in tcam while qos acl in other tcam?
thanks a lot!
1) you can configure different value, but the root timers setting are used. It makes sense to configure similar timer values on the backup root.
Note also that in MST (I don't remember if this is the case in RSTP in fact), the hello timer is now a local value driven by the designated port. On a given segment, all bridges use the hello-time advertised by the designated port. In theory, we should be able to configure the hello-time on a per-port basis. We did not implement the CLI in IOS (we did in CatOS).
2) yes with MST for the hello-time, as mentioned above. Max age is still driven by the root.
3) no clue;-)
