Configuring High Availability

  • 1.  Configuring High Availability

    Posted Feb 18, 2014 10:27 PM

    Hello,

     

    I was attempting to configure high availability on 6.3.1.2 and I had it all configured correctly.

     

    I had a 7210 local controller set as the active controller with 233 APs connected to it.  don't plan on adding many more.

     

    I have these other controllers available for use.

     

    3600 - master

    3400 - local

    3400 - local

    3400 - local

    3400 - local

     

    Can I use these other controllers as standby to cover all of my APs?

    The 3600 and 2 3400's should give me a total of 256 APs for HA.  Does it work this way?

     

    Also when I had just the 3600 connected I had a number of APs with the "S" flag when I did a show ap database.

     

    Does this just mean that HA was working?

     

    Thanks!

    You'll need to aps split into separate ap-groups and separate ap-system-profiles such that the backup-lms points to the different controllers.

     

    Personally, I would try to leave the master 3600 free from APs since you have the capacity with 4 x 3400 controllers.

     

    Provision 60 aps into each group, with the backup-lms to point to a 3400.

     

    I've not setup the HA feature with 6.3, but it should work with the above implemented.

    That is actually the way I have it set up currently.

    What is the difference between this setup and the high availability with fast failover?

    Normally when an AP failsover to the backup-lms, it has to go through the process of building the GRE tunnel before it can operate.

     

    With the HA or high-availability feature of 6.3 enabled, the APs will build this second tunnel to the backup-lms, thereby enabling it to come up quickly with minimal downtime in the event of a failover.

     

    The S flag on the controller means that AP is in standy mode but has already built the GRE tunnel.
