I am working on a plan to upgrade the Network to accommodate for a newly installed VoIP (none-cisco) solution and for the potential growth. The existing setup has around 14 3560’s dual-home to the Core (pair of 4510’s).
The plan is to upgrade the Core to a pair of 6509-E (SUP720), and re-use the 4510’s as access switches. Each 4510 will have a total of 300 100/1000 PoE ports to provide connectivity for users and phones. My concern is the uplinks between the 4510’s and 6509’s as I don’t see us getting the 10Gb interfaces, so I would have to use 1Gig or 2Gb channel for uplinks. Currently all the users have Gig to the desktop, but no one ever uses more than 5 or 10Mb at max. What are your thoughts regarding the uplinks speeds since it would be considered way over subscribed.
Thanks in advance
