•Description—Enter the description of the RTSP map, up to 200 characters in length.

•Parameters—Tab that lets you restrict usage on reserved ports during media port negotiation, and lets you set the URL length limit.

–Enforce Reserve Port Protection—Lets you restrict the use of reserved ports during media port negotiation.

–Maximum URL Length—Specifies the maximum length of the URL allowed in the message. Maximum value is 6000.

•Inspections—Tab that shows you the RTSP inspection configuration and lets you add or edit.

–Match Type—Shows the match type, which can be a positive or negative match.

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.
