Hello,
I would like to validate this kind of special deployment
I have a customer wth the following installation:
- 2 x VMMs running AOS 8.3
- 1 cluster of 2 x 7205 on HQ (same AOS version)
- 18 x 7008 controllers deployed on remote branches (same AOS version)
- 100+ APs
- DNS aruba-master pointing to the HQ cluster VIP
- On each branches the AP System Profiles are configured with the IP of the local controller as primary LMS and the VIP of the HQ cluster as backup LMS
During a recent upgrade (from 8.3.0.3 > 8.3.0.7) we had a strange behaviour of the APs when the branches 7008 were already upgraded but the HQ cluster was still running the old version, the APs were just flapping between the branches controllers and the HQ cluster and each time upgrading or downgrading the FW. When the HQ cluster was finally upgraded all APs register correctly to their own primary LMS.
- Is this kind of configuration really valid and supported ?
- What can be changed to mitigate the impact of temporary running mixed version ?
Kind regards
Christian Chautems
