Disabling Application Identification for Nested Applications
Sometimes there is a need to identify multiple different applications running on the same Layer 7 protocols. For example, both Facebook and Yahoo Messenger can run over HTTP, but there is a need to identify them as two different applications. To do this, the application layer is split into two layers: Layer 7 applications and Layer 7 protocols. Application identification for nested applications is turned on by default. You can manually turn it off by using the CLI.
To disable nested application identification:
- Set the no-nested-application statement.
To verify the configuration, issue the show services application-identification nested-application-settings command.
To reenable nested application identification:
- Delete the no-nested-application statement.
If you are finished configuring the device, commit the configuration.
