I am looking into making our (rather small) network more resiliant.
The attached files show the current network (CN.jpg) and the proposed network (PN.jpg). In the current network, the core switch is a CE500-12TC and the access switches are 3Com 4400-SEs with two CE500-24TTs.
I plan to implement 4 VLANs, for servers, printers, staff, and network management, so would want the distribution switches to be layer 3.
Firstly I am after any positive/negative comments about this design.
Secondly, what model of switch would you use for the core/distribution?
The access switches are being standardised as CE500-24TTs, except for the ones needing fiber connections with will be the 24-PC model.
