Spanning Tree Protocol

Yeah, I think im getting the concepts now,

thanks for helping.

You can have two root ports on a switch for different VLANs if you are running PVST or MST. This is not default behavior, but is configurable through VLAN port priorities.

jwj, as per zenzippy network I hope only NATIVE vlan is there..!

so this network will have only one root port...am I correct?

If you are focusing on only the original spanning tree specification, 802.1d, then yes, spanning tree runs only over the native VLAN. Now zenzippy never mentioned the capability of his switches, or whether he used VLANs, he just asked whether it's possible to have two root ports on a switch. The answer is yes as I explained in the previous post.

Trust me, it's possible, I do it for added reliability on my network at work. Check out this link for some quick descriptions of some of the spanning tree versions: www.cisco.com/en/US/tech/tk389/tk621/tsd...t_protocol_home.html

Ok...this concept is realy new to me...I will go through about this concept.

Thanks

The concept is pretty new to me, didn't even know there was a another version of spanning tree. thanks jwl.
