Host Parameters – NBAR
The NBAR-PD (Network-Based Application Recognition – Protocol Discovery) MIB is used to collect statistics
on all protocols (applications) seen on an interface. This feature can be useful for collecting application
information on interfaces that are not being monitored by the NAM, thus increasing overall application
visibility. However, it should be noted that NBAR-PD can have an impact on the performance of a device,
especially a switch with many ports.
Use the Setup > Switch/Router Parameters > NBAR Protocol Discovery task to check on the current
NBAR collection status. This task also allows the administrator to enable/disable NBAR on all eligible
interfaces and view the details of NBAR collection for each interface. NBAR collection changes take place
immediately on Catalyst OS devices, but the Save button must be used for the changes to take effect on IOS
devices.
Note: The NBAR Protocol Discovery feature is not available on all versions of switch software.
