Port Groups and forwarding

[mtbiker]

I have several 2900 series switches, some uplinking via gigabyte copper and other uplinks via port groups. I need some help understanding and configuring for performance. My "Core_sw" contains all servers the gatway router and uplinks to the other switches. It also has two gigabyte uplink ports and a single port group to another 2900 switch. The gigabyte connection goes to 2950 switch which is also port grouped to a 2924 with a fiber uplink to another 2924. Users are attached to switches off of the "Core_sw", all the way to the end or last switch.
there are NO loops. In configuring the port groups their is a configuration for source or destination forwarding. Suggestions on which would benifit me more. Source comes up by default, but I have been reading messages on this forum, and I get the feeling that destination is what I should have.
ALSO, STP... Except for the "Core_sw" the other switches have STP turned off, any thoughts on this?

I appreciate all your help.

If you are positive there are no bridging loops then you don't need STP.. But as for the port groups, I believe you want "destination" for when you're dealing with switch to switch..

Check

http://www.cisco.com

on port grouping... It'll give you the info you need..

The configuration is kind of like a + design.
The "core_sw" is in the center, and each of the switches that make up the legs are port grouped or gigabyte uplinked. Their is NO looping from switch to switch other than the port groups. I have them well identified using specific ports (1,2,3) on each of the switches. In the case of a gigabyte switch, then ports 1,2,3 are empty.

Thank you for the info on setting the forwarding to destination.

I have quiried cisco, but I have not received an answere to date.
