NBAR2 Custom Applications
NBAR2 supports the use of custom protocols to identify custom applications. Custom protocols support
protocols and applications that NBAR2 does not currently support.
In every deployment, there are local and specific applications which are not covered by the NBAR2 protocol
pack provided by Cisco. Local applications are mainly categorized as:
• Specific applications to an organization
• Applications specific to a geography
NBAR2 provides a way to manually customize such local applications. You can manually customize
applications using the command ip nbar custom myappname in global configuration mode. Custom
applications take precedence over built-in protocols. For each custom protocol, user can define a selector ID
that can be used for reporting purposes.
There are various types of application customization:
Generic protocol customization
• HTTP
• SSL
