Cisco Cisco Expressway Release Notes

The Expressway has a new API to simplify remote configuration. Third party systems, such as Cisco Prime
Collaboration Provisioning, can use the API to configure Mobile and Remote Access on the Expressway.

The API is self-documented using REST API Markup Language (RAML).
Large VM CPU Reservation Reduced
The Large Expressway VM CPU reservation requirement has been reduced from 25600 MHz to 16000 MHz. This
means that two Large Expressway VMs can now comfortably co-reside on a UCS server with two eight-core 3.2 GHz
processors, when hyperthreading is enabled. This was not previously possible because the higher reservation
requirement, added to the CPU requirement for the hypervisor, exceeded the total processing power of the host.

We now do an integrity check before you commit to an upgrade. This means you can't tell that the package is being
verified on this particular upgrade, because your pre-upgrade version does not have this feature. During your next
upgrade, you'll see package signing information, like this:
