We have a Dell stack switch (running RSTP) connected with a couple of Cisco switches (running PVST), and recently, something happened. I'm not sure where, but in our network, we started getting packet loss. Our network is big; it distributes to different, remote locations.
I have no idea who configured switches etc.
- Is it possible for RSTP and PVST to work together?
- Does it require any special configuration?
- In the core switch, I am sometimes seeing 'PortFast' Link UP and DOWN on the console. Is it because of spanning tree?
