We’re getting ready to refresh a significant number of edge closets and are looking to change up a few things. Our primary goals are:
- Support 2.5/5gbps links for our WAPs.
- Reduce/eliminate total downtime of the wired network and wireless network
- Save money
The current thought is to do something like the following:
- Place 2 higher-end switches capable of multi-gigabit links to handle the WAPs (max ~20 APs/closet)
- Fill out the remaining port needs with lower-end PoE switches
The question is, what’s the best way to accomplish the first 3 points following the second two. My initial thought would be to take the two higher-end switches (either 5520s or x465s) and set them up as an MLAG and the lower-end switches (either x440s or v400s) as a “stack” (with the understanding that V400s don’t actually stack and assuming that V400s can be uplinked to an MLAG). This should allow any one of the 3 entities to go down for whatever reason (hopefully just firmware updates) without taking the other 2 down.
Diagram of what I think is a good idea until people tell me why I’m being dumb:
Am I missing anything? I understand that nothing benefits from the MLAG except for the stack and the uplink to the core. Is there a better way to accomplish what I’m after?

Here is a small update:
The GTAC confirms the different statements in the documents and will clarify them with the product management.

Strange indeed,
in addition on the product page:
https://www.extremenetworks.com/product/ap510ie/
There is a hint regarding redundant poe (search for redundant on the web page).
I have opened a GTAC case and will write here what comes out of it.

Good to know. I checked the tech specs before and there it is written:
Interfaces•
(1) 100/1000/2500/5000 Mbps auto-negotiation Ethernet port, RJ45 PoE (Power over Ethernet 802.3at) Port. (802.3bz supported)•
(1) 10/100/1000 Mbps auto-negotiation Ethernet port, RJ45
Only for one of the two interfaces PoE is listed. Strange.
Best regards
Stefan

Hello Stefan,
I have not tried it, but according to the Quick Reference Guide for AP510Ie you can provide redundant power via both ethernet ports:

Hi,
the APs I checked support PoE only on one of the interfaces, so the backup port doesn’t really help, since the AP will be powered off. Or do I miss something?
