If this command is configured in the tunnel interface view, it takes effect only on the current tunnel interface.
If this command is configured in the system view, it takes effect only on the mobile IPv6 network.
Before running the tunnel ipv4-ipv6 traffic-class command in the tunnel interface view, run the tunnel-protocol ipv4-ipv6 command in the same view to set the tunnel mode to the IPv4 over IPv6 manual tunnel.
The configuration in the system view and the configuration in the tunnel interface view are independent of each other.
