Thanks for the reply.
I personaly don't understand why we need it, but our network guy is claiming that we need a proper core switch because it will make the entire newtwork more efficient. He is wanting to set up several vlans and as far as i know the IMS switch can do that as well. What we have so far is as follows.
(5) T1 lines going to other private institutions into (2) Cisco 1941 routers
(2) T1 internet lines for out web servers connected to
(2) DSL lines for internet access in our main office
all of the above internet lines go into a Cisco 2901 Router
All of the routers then connect to a Cisco 2960 interconnectivity switch
Then it passes through Sonic wall NSA2400 Firewall appliace
now is where i have the issue.
Option A IMS switches
Option B Cisco 3560
Then to (4) cisco 2960 access switches with POE
Then to roughly 50 IP phone with pass thru to workstations.
We previously had a much smaller network and added about 40 users so we had to rework things and bring in additional servers. I don't want to overcomplicate things and I am frankly sick of buying equipment. However if its needed or will benefit us in any way I have no problem doing so.
