Verifying and Monitoring SCCP Inspection
The show skinny command assists in troubleshooting SCCP (Skinny) inspection engine issues. The
following is sample output from the show skinny command under the following conditions. There are
two active Skinny sessions set up across the ASA. The first one is established between an internal Cisco
IP Phone at local address 10.0.0.11 and an external Cisco CallManager at 172.18.1.33. TCP port 2000
is the CallManager. The second one is established between another internal Cisco IP Phone at local
address 10.0.0.22 and the same Cisco CallManager.
