Adding zones to Clearpass

    We have a globally distributed deployment of Clearpass and want to enable additional Zones to regionalise authentication state, etc and avoid having this replicated to all servers in the cluster unnecessarily.

    Is there any impact in configuring these zones and assigning cluster members to them that we need to consider? What is the immediate impact to cluster members that were previously in the default zone but whom will now be in a US, EU or Asia zone? Does the cluster continue to operate normally during the change? Should this be done outside of production hours, etc.

    Check here for guidance on the use of zones in ClearPass.

    You should put ClearPass nodes in the same zone if the same device is likely to authenticate on different servers in that zone.

    I'm quite sure that there is no interruption if you change ClearPass servers to a different zone. The 'hot data' may be out of sync shortly after that, but recover quickly. If you heavily depend on Cached Roles (like OnGuard), you may consider making the change in a maintenance window. And probably it's a good practice to run all changes in an maintenance window anyway so your users know that things may have changed and they report possible issues.
