3Com Switch 4200G Configuration Guide

Setting the Precedence of Protocol Packet 233
acl-rule: Issued ACL rules which can be the combination of various ACL rules. The way
of combination is described
Table 202.
Clearing the Traffic
Statistics
Configuration Example
■ The GigabitEthernet1/0/1 of the switch is accessed into the 10.1.1.1/24 network
segment
■ Perform traffic statistics on packets form the 10.1.1.1/24 network segment
Configuration procedure:
<S4200G> system-view
System View: return to User View with Ctrl+Z.
[4200G] acl number 2000
[4200G-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255
[4200G-acl-basic-2000] rule deny source any
[4200G-acl-basic-2000] quit
[4200G] interface gigabitEthernet1/0/1
[4200G-GigabitEthernet1/0/1] traffic-statistic inbound ip-group 2000
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.
Configuration
Prerequisites
■ The protocol type whose precedence needs modification is specified
■ The precedence value after modification is specified
Configuration Procedure
