Wireless Access

Hi All,

 

I need some clarification and solution about HP MSM760 failover and redundancy. Recently we have just purchased 2 units of MSM760 Controller. Is it possible for me to configure the controller to be Active-Passive mode? I can see that there is teaming option but that one required additional license.

 

At the moment I understand that once first controller goes down, the AP will join to 2nd controller but the problem right now is we need to do configuration manually at both controller. Is there any way that I can synchronize both controller if I do any config changes on the controller.

 

Thanks in advance

No, I dont think so. Thats what the teaming is for.

Once teaming is enabled the Team Manager will be managing both controllers and any changes is auto synchronized on both controllers so no need to manually change both controllers :) the only thing you will need to do is the initial teaming config in both controllers that's it.

I've bought licensing so that either controller can manage the full complement of access points.

 

What I've found is this...

 

Some components of your configuration are syncronized between the controllers.

 

Some are not (public access web pages and attributes have to be manually syncronized if you've made any changes)

 

If you use guest access/web authentication, you must move your dhcp to an external server... (it's pretty straight forward).  Address translation is a bit more obnoxious...

 

The Virtualized controller IP address uses the same mac address as the primary controller (which can cause ICMP connectivity problems - though it seems much better under later rev's of code)...

 

Things get broken out a little as far as where to go to configure what... I find I have to search back and forth between the team level configuration and the controller level... note that you have to actually connect to the secondary controller for some configuration changes such as the public access files and attributes)

 

The system tends to somewhat load balance access points between controllers...

 

I also found that I needed to make some changes in the egress for my internet access... I've placed my "Internet" vlan in a dmz and then address translate the out-bound connections on the campus ASA...
