Purpose

Verify that the dynamic call admission control (CAC) configuration supports sufficient bandwidth for VoIP traffic.

Action

From the operational mode in the CLI, enter show tgm dynamic-call-admission-control.

Sample Output

user@host> show tgm dynamic-call-admission-control

Reported bearer bandwidth limit: 3000  Kbps
Interface       State         Activation    Bearer bandwidth
                              priority      limit (Kbps)
ge-0/0/3.0      up                     200                 3000

Meaning

The output shows the dynamic CAC configuration. Verify the following information:

The activation priority and bearer bandwidth limit (BBL) configured on individual interfaces are correct.
The Reported bearer bandwidth limit field displays the bandwidth available for VoIP traffic. Ensure that the bandwidth is sufficient for VoIP traffic.
