With DAR packet statistics function, users can timely monitor the packet number,
data stream volume, historical mean rate and historical maximum rate of
application protocol on each interface, thus to facilitate implementing
corresponding policies for the data streams.
Follow these steps to configure DAR packet statistics function:
To do...
Enter system view
Enter interface view
Enable DAR packet statistics
When large data volume goes through the device, it often takes too many system
resources to recognize them one by one with DAR, which also impacts working of
other modules. To avoid the case, users can limit the maximum number of
connections that can be recognized by DAR in order to save system resources.
When the connection number exceeds the maximum threshold, DAR will not
recognize it and directly mark it to be unrecognizable.
Follow these steps to configure the maximum connection number recognizable by
DAR:
To do...
Enter system view
Configure the maximum
connection number
recognizable by DAR
After the about-mentioned configuration, you can use the display command in
any view to view the DAR running information, so as to verify configuration result.
Execute the reset command in user view to clear the DAR statistics and session
information.
Follow these steps to display and maintain DAR:
To do...
Display DAR module information
Display DAR protocol information
Display user-defined protocol rename information
Display DAR packet statistics information
Use the command...
system-view
interface interface-type
interface-number
dar protocol-statistic
[ flow-interval time ]
Use the command...
system-view

count
Use the command...
display dar information
display dar protocol { all |

display dar protocol-rename
display dar protocol-statistic
[ protocol protocol-name | top
