This article describes how to configure quality-of-service (QoS) policies with differentiated services code point (DSCP) for LAN (local area networks) in your CrashPlan environment. Using DSCP can help prioritize backup traffic from CrashPlan apps to the CrashPlan cloud while not saturating your network.
Options for configuring DSCP are only available at the organization level in the CrashPlan console, not at an individual device level.
Configuring DSCP settings only affect LANs where routers are configured to support DSCP, and where other services use the same ports as CrashPlan. DSCP is a topic for experienced network administrators and is beyond the scope of our Customer Champions. Incorrectly configuring these settings can adversely affect network performance and impact CrashPlan app connectivity.
CrashPlan apps on Windows
DSCP settings configured via the CrashPlan console do not apply to CrashPlan apps running on Windows. To use DSCP for CrashPlan apps running on Windows, you must enable DSCP via Group Policy.
Before you begin
- Consider the IP addresses used in your environment. Specifically, ensure you are familiar with your use of IPv4 and IPv6, as applicable. If your use of IPv4 or IPv6 changes after you enable DSCP, revisit these CrashPlan console settings to ensure they are still appropriate for your environment.
- You must have Org Admin or Cross Org Admin level permissions or higher to configure DSCP.
- Sign in to the CrashPlan console.
- Select Administration > Environment > Organizations.
- Choose an organization.
- From the action menu, select Device Backup Defaults.
- Select the Network tab.
- Under DSCP, select Enable DSCP.
- Select IPv6 or IPv4.
- If you select IPv6, DSCP is not set on IPv4 packets.
- If your environment only runs on IPv6, do not select IPv4. Selecting IPv4 forces all communication over IPv4. If you select this option in an environment that only runs on IPv6, your CrashPlan apps will be cut off from the CrashPlan cloud and can only be recovered by uninstalling and reinstalling the CrashPlan app.
- Enter a DSCP Value between 1 and 63.
- (Optional) Select the Push button to apply this setting to existing devices in addition to new devices.
- Select Save.
