Can we stack 3 units of ERS 5698 switch
« on: March 30, 2015, 07:23:29 AM »
Can we stack 3 units of ERS 5698 switch together. I have seen other AVAYA ERS models in stacking , but never heard about stacking of ERS 5698.

If we can stack , Can we stack it with other ERS  models

Yes , I have lot of money.

Hello Faizan,

yes, you can stack the ERS5698 with all other ERS5xxx models.

Some things to keep in mind though:
-if you stack a 56xx model with a 55xx model, you will need to put the 56xx model into "hybrid" mode before stacking it, as it will need to fall back to a lower stacking speed to be compatible with the older 55xx models
- if stacking with 55xx models, use the 56xx as base unit
- a stack can normally consist of maximum 8 units. but when using the 5698, you will have less because your stack cannot contain more than 400 ports..


But as you are writing you have a lot of money, don't buy the 55xx anymore, only buy 56xx

The 5698 counts as 2 (two) units when stacking - think of U-size as a stack size counter for a maximum of 8. So, four 5698s is the maximum stack size you can have. However, you can mix it with 5650s if that works out in your wiring closet.

It's possible to stack it with 5500-series switches, just remember which mode you put it in. I would definitely prefer splitting up in two stacks rather than mix 5600 and 5500, but it's possible. Btw, never, EVER, mix in 5510s in your stacks. They are old with a slow cpu and little memory and cause problems with mixed 5500-series stacks (5520/5510). How it would behave with 5600-series I wouldn't want to find out...

Mixed stacks have some recommendations and limitations:
  • Use a 5600-unit as base
  • 5632 lose ports 31 and 32 in hybrid stacks
  • Place 5600 adjacent to each other
  • Blue stacking cables between 5600s, either cable between 5600 and 5500

Apart from that - stack away!

If you have some time before implementing the new switches and you have not yet bought them, it might be interesting to wait for the new ERS5900 series instead of investing in "end of sales" material..

Thank you Johan & onikolaisen !!

It is much clear know. We can stack EoS ERS 5698 switch.

One more doubt , what is replacement for ERS 5698 in ERS 5900 series? Or we have to be happy with VSP 8000?

Closest match with 5900 would be the ERS5952GTS, as it is 48 ports you'll need 2 for 1 ERS5698.

If you really need higher port density within 1 box you'll have to move to the VSP8284 with 84 ports and a higher price tag, and it's still 10 ports less...

All I have on the 5900-series is some old NDA which I'm not at liberty to divulge. However, looking at some other people's published information, there's no direct replacement for the 5698. There will be a 5928 and a 5952, both with 4x SFP+ and full SPB built in as well as with or without PoE+. Presumably (hopefully) there will eventually be SMLT and MacSec support in order to make it a viable TOR/BOR replacement for the 5x00-series in the data center.

Have a look at http://networkautobahn.com/2015/03/03/news-avaya-ers5900-switches/ for some nice pictures...  8)

Btw, the VSP8000 series isn't really a replacement for the 5698. Yes, you can have up to 96 10G ports (wired or optical), 24 (really 32) 40G ports or any combination you can imagine in the 8400. With regards to price - the VSP8000 series is a BCB for most networks and a BEB for large networks, not an access switch.

Hi folks, just for information - there also a ERS59100GTS available.
I saw that box in February on the ATF.

We standardized on the 5698-TFD-PWR several years ago, and were just about to buy a bunch more when the EOS notice was released.
We have projects that cannot wait on the 5900.
Based on this, we are moving forward with 4850's instead of 5698's, as the current build gives us everything the 5698 can except for SMLT and route limitations.  For most of our smaller sites, these finally appear to be a fit with 5.8 release giving us PIM capabilities.
So, 5698 - internal RPSU, POE, dedicated 10 gig and shared 1 GIG fiber, FA Proxy, PIM, LACP, SMLT, ADAC, LLDP-MED, menu, 4000 routes, IPFix.
4850 - internal RPSU, POE+, dedicated SFP+ and shared 1 GIG fiber, PIM, LACP, ADAC, LLDP-MED, 512 routes, IPFix.
We have less than 400 routes now that we are doing Static Routing to an adjoining hospital, so we are good to go.  We are only running SMLT in our legacy Data Center on the 5698's.  The rest are L-3 MDF for small buildings and L-2 edge.
Based on the joint announcement of both 55XX and 56XX being EOS, (very abruptly to us I might add) we had several hours-long discussions with Avaya and our plan of record.  It looks like the latest ERS4800 code brings what we needed to replace the 5500's (L-3 and L-2) along with enough to move the 5600's out over time.  It gives us POE+ immediately (not that we need it) and let us see the evolution of the 5900's from a safe but supported distance.

As I've seen significantly faster code development on the 4800s than the 5500/5600's in the past, this decision gets us onto the forefront of new features faster as well.  I know we will lose some of the latest and greatest features the 5900 can bring, but we have yet to hit any technical limitations with our existing 5500/5600/8600 hardware (except we keep running out of ports!).  The 4850, being a near 100% match now for the 5520 with the advantage of POE+ and internal hot-swap RPSU, we are going to be fine.
