How to set up RSTP for HP switches 2650 which is connected to cisco 2821 ? Should I change anything on cisco device ?
We have a problem sometimes with our mitel phones, if somebody plugin 2 cables into it, it creates a network loop, this why I am going to use RSTP to prevent it.
this means that PVST+ is running on cisco module
>> Spanning tree enabled protocol ieee
each instance follows 802.1D standard (legacy STP) that is not Rapid STP
interation with HP switches can be on vlan1 with a single instance.
If this module is central device in your topology enabling Rapid STP 802.1W or 802.1s on HP switches can be of limited help for overall convergence.
Hope to help
