Hello Everyone,
I open this discussion to have some help about roaming between two IAP cluster and L3 Mobility Domain.
First of all, some technical elements :
OLD Cluster :
- IAP models : 204 and 304
- Version : 6.5.4.21
New Cluster :
- IAP models : 504
- Version : 8.7.1.9
Each cluster has its own "APs VLAN".
Context :
Renew of a cluster of 91 AP in a factory. In this factory, there is moving robot which transport parts. Robots are highly criticals and need to roam often.
Density of AP in this factory is really high.
Current APs (model 204, 90% of old cluster), because of the firmware, are not compatible with new APs (504) and cannot form a cluster.
A big bang migration isn't possible because of the huge number of APs, their accessibility and the 24/7 activity of this factory.
A scenario of progressive migration have been chose. With, APs by APs replacement.
For this scenario we need an highly effective roaming for robots. We use L3 Mobility Domain between old an new clusters.
SSID's VLAN remains the same between clusters.
I have read some documentations and discussions about L3 Mobility Domain.
In particular, these :
https://community.arubanetworks.com/browse/articles/blogviewer?blogkey=0c0d55c0-e6e7-4767-96d4-95871e6745e1https://community.arubanetworks.com/community-home/digestviewer/viewthread?MID=23941#bme131b5da-9e3f-4a5d-aa2d-d28d7e053fafhttps://community.arubanetworks.com/community-home/digestviewer/viewthread?GroupId=7&MID=21085&CommunityKey=867d34a4-1e6a-4b9a-9349-df7b4c84b3cb&tab=digestviewerIn fact, our L3 roaming fail. And, by reading these documents, I understand that L3 Mobility Domain needs SSID VLAN deployed only on a single cluster. Which isn't compatible with my case.
So my questions are these :
- SSID's VLAN on only one side of the domain is mandatory, or not ?
If not, is a L3 Mobility Domain configuration example available ?
If yes, except a "classic" roaming between two clusters unknown to each other, Is there another way to facilitate roaming in this scenario?
Thanks for your help everyone.
