Renaming user-defined protocols

By default, the names of the ten user-defined protocols are user-defined01, user-defined02,…,

user-defined10. You can rename them following these steps to assist memorization and management.

To rename user-defined protocols:

Ste

Command

1. Enter system view.

system-view

2. Rename a user-defined

protocol.

Configuring DAR packet accounting

With the packet accounting function of DAR, you can monitor the number of packets, the amount of data

traffic, the historical average traffic rate, and the historical maximum traffic rate of application protocols

on each interface. According to the statistics, you can apply a correct QoS policy to the traffic.

To configure DAR packets accounting:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Enter interface view.

interface interface-type interface-number N/A

3. Enable DAR packet

accounting.

By default, DAR is

disabled.

Configuring the maximum number of recognizable connections

DAR tasks are resource intensive. To prevent DAR tasks from affecting other network services, you can

limit the maximum number of sessions that DAR can recognize. The limitation applies to HTTP, FTP, RTP,

and RTCP. After the limitation is reached, DAR marks all incoming packets of these applications as

unrecognizable. For the packets of other TCP/UDP protocols, DAR continues to perform packet

recognition.

To configure the maximum number of connections recognizable to DAR:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Configure the maximum

number of recognizable

connections.

dar max-session-count count Optional.
