1.6 Setting the Precedence of Protocol Packet

The protocol packet carries its own precedence. You can modify the precedence of the
protocol packet through setting its precedence. And then you can match the
precedence with the corresponding QoS action to perform the corresponding QoS
operation on the protocol packet.
1.6.1 Configuration Prerequisites
The protocol type whose precedence needs modification is specified
The precedence value after modification is specified
