1.5 Setting the Precedence of Protocol Packet
The protocol packet carries its own precedence. You can modify the precedence of the
protocol packet by 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.
1.5.1 Configuration Prerequisites
z
The type of protocol whose precedence needs modification is specified
z
The precedence value after modification is specified
