Overview Application inspection and control for instant messaging recognizes and controls the traffic from specific brands and versions of instant messaging software. Cisco introduced classic firewall support for application inspection and control for instant messaging traffic in two phases. The first phase introduced application inspection and control for instant messaging carried on TCP 80 (typically used for HTTP) in Cisco IOS Software Release 12.3(14)T. Application inspection and control for native instant messaging was introduced in the second phase, in Cisco IOS Software Release 12.4(4)T.
