Custom application enhancements

Devices supports custom applications signature functionality by providing a new set of applications and contexts. Application identification allows you to create custom application signatures to detect applications specific to your network environment. You can create custom application signatures for applications based on ICMP, IP protocol, IP address, and Layer 7 or TCP/UDP stream. While configuring the custom application signatures, you must specify the context values that the device can use to match the patterns in the application traffic. Custom application signature contexts are part of application signature package. You must download and install the latest application signature package version 3248 or later to use new contexts for custom application signatures.
