The tunnel ipv4-ipv6 traffic-class command sets the traffic level of the IPv4 over IPv6 tunnel.
The undo tunnel ipv4-ipv6 traffic-class command restores the traffic level to the default value.
By default, the traffic level of the IPv4 over IPv6 tunnel is 0.
tunnel ipv4-ipv6 traffic-class { original | class-value }
undo tunnel ipv4-ipv6 traffic-class
| Parameter | Description | Value |
|---|---|---|
| original | Indicates that the value of the Traffic Class field in the IPv6 field of the IPv4 over IPv6 tunnel header uses the value in Traffic Class field of the original packet. | - |
| class-value | Specifies the traffic level of the IPv4 over IPv6 tunnel. | The value is an integer that ranges from 0 to 255. |
Usage Scenario
The traffic level of the IPv4 over IPv6 tunnel packets refers to the value of the traffic class field in the tunnel packet header of the ingress on the tunnel.
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.
Prerequisites
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.
Precautions
The configuration in the system view and the configuration in the tunnel interface view are independent of each other.
