RTSP Class Map
Configuration > Firewall > Objects > Class Maps > RTSP
The RTSP Class Map pane lets you configure RTSP class maps for RTSP inspection.
An inspection class map matches application traffic with criteria specific to the application. You then
identify the class map in the inspect map and enable actions. The difference between creating a class
map and defining the traffic match directly in the inspect map is that you can create more complex match
criteria and you can reuse class maps. The applications that support inspection class maps are DNS, FTP,
H.323, HTTP, IM, SIP, and RTSP.
Fields
• Name—Shows the RTSP class map name.
• Match Conditions—Shows the type, match criterion, and value in the class map.
–
Match Type—Shows the match type, which can be a positive or negative match.
