Does WLC 2504 Supports HA or not ?

     We are already having Cisco WLC 2504(software version:7.3.101.0) in our Network and managing 10 access points, we are now trying to build High Availability ( HA ) in the WLAN setup. So I am in need of details that this existing platform is capable of supporting HA.

Required Clarifications as follows.

1. Does WLC 2504 support HA?
2. If HA is supported whether any license is required to enable it.
3. What is the Software Pre-requisites to enable it.
4. Configuration guide to enable HA

HA is suppose to be supported in v7.5 which should be available in a month or so.

Re: Does WLC 2504 Supports HA or not ?

From what I know is that you would be able to configure AP SSO on the 2504. Now since I don't know if there will be a HA sku or not, we will have to wait to get more info on the minimum license to run HA just like the 5508's for example.

Re: Does WLC 2504 Supports HA or not ?

    Are you trying to convey that  High Availability is enabled in the BoX right now, or it will be enabled only when we get the 7.5 code ?

 

    Is any reference doc is available in cisco site to inform that HA will be supported in 2504 model ? thus i can consider this model for HA ?

  I am looking this information at the earliest, thus i can propose the WLC 2504 for redundancy,.

As on today if WLC 2504 is not supporting HA  and there is no concrete road map on the dates when 7.5 code or SKU details , then i need to go for other model of WLC which currently supports HA. In this case i am being forced  to remove my existing WLC 2504 and replace with two new WLC.

Request your expert help in this case

Thanks ... Ram

Re: Does WLC 2504 Supports HA or not ?

Until a few days before the v7.5 release, Cisco will make the release notes available. Until then, I don't have any specifics. HA on the 2504 doesn't exist now and will be available on v7.5.

@Scott I don't see Cisco has

@Scott

 

I don't see Cisco has any plan to have SSO HA built for WLC 2504 . I don't see it under WLC running code 7.6.130

Thanks, Kunal Happy to help you !

That is correct. There is no

That is correct. There is no plan to support SSO on the 2504, just N+1.  You would need at least two 5508's

Re: Does WLC 2504 Supports HA or not ?

I'm assuming your look at HA in regards to AP SSO and not just a redundant WLC in active active?

Does WLC 2504 Supports HA or not ?

My requirement is as follows:

    If the Existing WLC - 2504  fails for any reason ( Hardware / Software ) the Access points should assosiate to the Redundant WLC. i.e. I am looking for  Active / Standby mode.

Clarifications Required:

    My  WLC 2504 current code ( software version:7.3.101.0) will it support the above requirement ?

    How AP SSO differs from HA ? will it converge fast ?

Re: Does WLC 2504 Supports HA or not ?

So I was wrong... AP SSO will not be supported in v7.5 only N+1.  So you either can do N+1 or just do the normal primary and secondary.  No matter what, you will have downtime if the WLC goes down, but shouldn't be longer than a minute with either way.

Thanks,

Scott

Re: Does WLC 2504 Supports HA or not ?

You need to understand what is what. If you have redundant WLC's no matter what code, you can support AP failover with no issues. You basically set the primary and secondary WLC in the access points high availability tab.

HA in v7.3 is what the call AP SSO (state full switchover). The 2504's doesn't support this until v7.5 which isn't available yet. HA AP SSO isn't very stable with current releases, so just doing the normal redundancy should work for you.

Re: Does WLC 2504 Supports HA or not ?

Hi Scott,  As per my understanding the WLC with current code v7.3 supports the primary and secondary WLC configuration for High Availability.

  Do my current code also support N+1 redundancy ?

  Let me know any reference doc to show different between different HA modes.

Thanks, Arun......

Does WLC 2504 Supports HA or not ?

HA with AP SSO is only supported in v7.3 and v7.4 on the 5508, WiSM, 7500, 8500.  N+1 is used with the HA sku WLC.  Primary and Secondary high availability on the AP has been supported a long time ago.

Thanks,

Scott
