Solved: Re: simple RSTP configuration

ohalnet53 · ‎04-02-2008

hi

I like to connect my Catalyst 3560 and Catalyst 2960 Switches and need to configure related ports in order to prevent loop.

I know how to configure STP but dont know how to configure ports to run RSTP ...

could someone help me please?

There's not a lot to it really. On your switches

switch(config)# spanning-tree mode rapid-pvst

That's about it really. You don't need uplinkfast or backbonefast as these are incorporated into RSTP and the rest of the setup is the same as 802.1d.

thanx jon it was really helpful

but I shoul enter this command under the interface not on global mode right?

because I want other ports to run "spanning-tree port fast

No this should be entered under global. Spanning-tree portfast is still used under RSTP so you can configure portfast at the interface level buit the spanning-tree mode at global level.
