I am working on a network design for one of my company’s newly aquired buildings. I am trying to implement a network design that keeps spanning tree to a minimum but offers uplink redundany. We were approved and have recieved the following equipment for the new site.
2 Cisco 6509 switches running IOS
1 24 Gigabit fiber SFP blade in each
1 supervisor 720 blade in each.
12 Cisco 3750 48 port POE, with 2 Gig SFP’s
2 3750’s per wiring closet. Configured with two vlans per stack one for data and one for VOIP.
Initial config i came up with is running one port of each 3750 to the first 6509 and the second port to the other 6509. Running a 3 member 1 Gigabit Portchannel between the two 6509’s and VRRP running for each VLAN alternating between the two 6509’s for a more load balanced design.
My questions are:
1. Is this a good design, are thier improvements that could be made?
2. What if any spanning tree would be needed?
I have additional network information if needed, i did not include do to space limitations, including a visio diagram and a intial ios config of one of the 6509’s.
Please email any questions to scrobins@guidant.com
