Setting the DSCP value for outgoing DNS packets
About the DSCP value for outgoing DNS packets
The DSCP value of a packet specifies the priority level of the packet and affects the transmission
priority of the packet. A bigger DSCP value represents a higher priority.
Procedure
1. Enter system view.

2. Set the DSCP value for DNS packets sent by a DNS client or a DNS proxy.

IPv6:

IPv4 DNS configuration examples
Example: Configuring static domain name resolution
Network configuration
As shown in Figure 37, the host at 10.1.1.2 is named host.com. Configure static IPv4 DNS on the
device so that the device can use the easy-to-remember domain name rather than the IP address to
access the host.
