Hello to everyone, this is my first post on this forum. I googled a couple other forums but this onehas a fair amount of activity. I hope that I can contribute back to the forums as well. With that being said here is my question:
On my network there is a project in place to upgrade the switching LAN at two sites from 100Mbps to full gigabit. All switching nodes are connected back to an MDF via 1Gbps multimode fiber. This occurs via a straight home run OR through an intermediary hop between 1 or more IDFs.
My concern is that the fiber backbone will need to be upgraded to 10Gbps (no small task in regards to labor and $$$) to match the capabilities of the the current network architecture. Are my concern warranted or is there something I have not considered?
The network currently utilizes 3Com 4400 and 4900 series switches. the incoming switches will be Nortel 5510, 5520 and 5530 series. I am also concerned about auto-negotiation between brands during the transition between manufacturers (which will occur over the course of 1.5 years).
Thank you in advance!
