Adjusting Quality of Service for Commvault Network Traffic on Clients

Applies to: Windows and UNIX clients

If you have clients where the Commvault software competes with other applications for bandwidth, you can adjust the Quality of Service (QoS) of the Commvault network traffic by setting the appropriate Differentiated Services Code Point (DSCP) value on clients or client computer groups. The network routers will classify the Commvault data packets based on the DSCP value that you configured. By default, Commvault uses DSCP value 0 (best effort).

QoS is the quality of data transmission in the Internet (or intranet). The goal of QoS is to efficiently use the network by providing higher quality transmission to certain subsets of data.

DSCP is a computer networking architecture that manages network traffic and provides QoS on IP networks.

In the networking industry, the operation of setting DSCP values on Commvault data packets is known as QoS packet marking. The transmission quality of the Commvault data is determined based on the DSCP value that you set.

Before You Begin

To adjust the QoS on multiple clients, add the clients to a client computer group, and then set the DSCP value on the client computer group. For information on creating client computer groups, see Creating a Client Computer Group.

Procedure

To the client or client computer group, add the qosDscp additional setting as shown in the following table.
