Replacing a PAC File

If you use manual PAC provisioning, you must avoid allowing the PAC file to expire.

When you create a PAC file on the Cisco ACS, it has an expiration date determined by the Tunnel PAC TTL property. The best practice is to set the Tunnel PAC TTL property to 5 years or more so that you do not have to replace the file frequently. If you choose to set Tunnel PAC TTL to a shorter duration (for example, 1 year), ensure that you replace the PAC file on the Vocera Voice Server before it expires.

Important: The badges cannot authenticate or download an updated PAC file from the server if the badges are connected to the Vocera Voice Server when a PAC file expires. In such scenarios, you need to reconfigure badges that were connected to the Vocera Voice Server when the PAC file expired.

If you use automatic PAC provisioning, replacing a PAC file on the Vocera Voice Server is not required. The PAC is automatically provisioned by the ACS.
