Debug Messages and Show Commands on the Cisco IOS Gatekeeper
In the previous section, the Cisco CallManager SDI trace was discussed in detail. In the topology
for this case study, “debug ras” has been turned on in the Cisco IOS Gatekeeper.
The following debug messages show that the Cisco IOS Gatekeeper is receiving the admission
request (ARQ) for the Cisco CallManager (172.16.70.228), followed by other successful RAS
messages. Finally, the Cisco IOS Gatekeeper sends an admission confirmed (ACF) message to
the Cisco CallManager.

The following debug messages shows that the Cisco IOS Gatekeeper has received a disengaged
request (DRQ) from the Cisco CallManager (172.16.70.228), and the Cisco IOS Gatekeeper has
sent a disengage confirmed (DCF) to the Cisco CallManager.
