redundant controller with HP 830

[nskarim]

Hi Folks,

I have seen a question regarding high availibility on HP 830 without answer posted since couple of months

I thought of posting a new question to have a chance to get an asnwer.

I am considering deploying a solution with 2 HP 830 as redundant controller. However i do not see any guide in the documentation specifying high availability deployment for this device. Is it supported on HP830? I have rather seen such guide for HP850.

Thanks

Karim

Hi Karim.

Take a look at this link:

http://h17007.www1.hp.com/us/en/networking/products/mobility/HP_830_Unified_Wired-WLAN_Switch_Series/index.aspx#technical

See the "HP UWW High Availability Configuration Guide".

HTH.

Hi,

830 supports ap-based failover (aka cold failover).

* Configure the same wlan-ess/wlan service-templates/ap templates on both

* configure 830-1 with "wlan backup-ac x.x.x.2" (ip of 830-2)

* configure 830-2 with "wlan backup-ac x.x.x.1" (ip of 830-1)

* If aps are L3 discovered, configure both controller IPs as DHCP option 43

APs will open tunnel to both controllers (1 Master/ 1 Backup).

APs perfom controller echo (hello) every 10sec by default (can be set to 5 sec minimum), after 3 failed replies, AP will switch to other controller (backup tunnel becomes master tunnel).

Failover takes about 35-40sec.

All users need to re-auth (since online user state is not synced).

850/870/20G module support hot backup, which does sync user state and fast peer down detection (for 1-2sec failover),

best regards,Peter

Hello 

What about "master-ac ip x.x.x.x" command introduced in latest versions?

I thought is it supposed to tell slave AC which one is main AC, no?
