Title: Avaya SPB advice
Post by: subnet11 on May 30, 2017, 11:05:59 AM
Hello All,

Currently looking to go towards avaya SPB. Avaya has a Campus Lan reference design available.
I have 2x 5632 switches and a bunch of Edge switches (55xx series)
I was thinking to replace my 5632 switches with the 4450 switches and configure SPB.
If I look at the config of the edge it is just the same as a traditional network.
Does it mean if I use spb on the new core switches and configure via VLACP to current (55xx) series everything should work normally ?
Avaya uses the 4850 in their guide, but I assume any possible ERS switch should be workable right ?

We are looking at something similar, but larger scale.
The VSP switches do OSPF and SMLT out of the box, so you could build it identically the same as you have now. 
5500's don't do SPB Proxy, only the 5600's do.  However, you can build SPB style rules with IDE as your 802.1X port manager and simulate the basics - VLAN assignments, policy assignments, etc.  It won't get you the complete flexibility, since the VLANs have to first exist in the 5500's before you start on the uplink port and on the downlink ports of the VSP4450's.  With SPB and SPB Proxy availabe on the 5600's and 4500's, you can build/remove the VLAN/ISID connection on the fly with IDE.

Note, we have been extensively labbing this scenario, so while we am not using SPB daily, we found ways to simulate what we needed - and that was in a lab with a 5520 Core stack with 4500's, 5600's and 4900's connected to the stack.
