With the new Access Swhich (3550 etc) one of my customer is trying to implement a two layer design (core and access) no distribution. Argument: he can implement Security on the Access Layer. Which argument cann i use to convince him to implement a three layer design ?
For a Small Sampus design with less than 100 or so end stations (including all kinds of edge networking devices)it won't hurt to collapse the core and distribution layer into 1 layer like what you customer is doing. But obviosly this limits future growth and scalability of the model. You need a solid core and distribution layer in Multilayer model so you can grow bulding blocks, which need aggregation into the upper layer. A Small Campus design restricts that. Also keep in mind where you use fixed configuration switches as opposed to modular switches, again for scalability, future growth and performance, modular switches tend to have a longer life cycle.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
