Table 204 Setting the precedence of the protocol packet
Set the precedence of
the protocol packet
Display the
precedence of the
protocol packet
Set the IP precedence of the ICMP protocol packet to 3.
The configuration procedure is as follows:
<S4200G> system-view
[4200G] protocol-priority protocol-type icmp ip-precedence 3
[4200G] display protocol-priority
After finishing the configurations mentioned above, you can execute the display
command in any view to check the running state of QoS after the configuration. You
can verify the effects of the configurations by checking the information on display.
