Load balancing using site default device pool#

Tip

Use the Action search to navigate Automate

This procedure load balances using the default site device pool and updates the default device pool to point to the appropriate Cisco Unified Communication Manager (Cisco UCM) group.

Note

A default device pool is created for each site when the site dial plan is deployed for the Type 1 through Type 4 dial plan schema groups.

Since you’re using the default device pool, you don’t need to create any additional device pools directly on CUCM. Using this configuration, redundancy is gained within a site while load balancing is gained across multiple sites. Since there is one device pool per site, all devices at a site home to the same sequence of CUCMs, providing failover redundancy. Devices in different sites home to different sequences of CUCMs, providing load balancing across the sites.

The default site device pool is not created until the Type 1 to 4 site dial plan has been deployed, which updates the Site Defaults to use the default device pool. If the site dial plan has not been deployed, you will not see a site default device pool in the form Cu<customerId>Si<siteId>-DevicePool.

In Automate you can determine the default device pool for a site in the site Defaults page.

Perform these steps:

  1. Log in as Provider, Reseller, or Customer administrator.

  2. Choose the relevant site.

  3. Follow the steps outlined in Create a Site Dial Plan if you have not already done so; the Create a Site Dial Plan procedure creates the default site device pool instance.

  4. Log in to Cisco Unified Communications Manager and create one or more UCM groups.

    Note

    See Cisco Unified Communications Manager Administration Guide.

  5. In Automate, perform a sync operation of the UCM via the Data Sync page.

    This sync updates the Automate cache and makes the UCM groups that were added directly on Cisco Unified Communications Manager available to Automate.

  6. Associate a UCM group to a device pool and choose a UCM group other than the default group in the Call Manager Group drop-down list. See “Associate a CUCM Group to a Device Pool”.

    Note

    To verify that the phone or user uses the device pool as expected, open a user’s settings in Automate, then select the required Device Pool Name setting from the drop-down under the Phones tab.
