For output and description of the related commands, refer to the “3Com
Command Reference Guide”.
Example: QoS
Configuration
The interconnection between different departments on a company network is
implemented through the 100M ports of the Ethernet Switch. The payment query
server of the Financial Department is accessed by Ethernet1/0/1 (at 129.110.1.2).
It is necessary to limit the traffic from the server to other department to no more
than 20M.
Figure 3 Access Control Configuration Example
Note: In the following configurations, only the commands related to QoS/ACL
configurations are listed.
Define the traffic accessing the payment query server:
1 Enter the named advanced ACL view, identified as traffic-of-payserver.
[SW7700] acl name traffic-of-payserver advanced match-order config
2 Define advanced ACL traffic-of-payserver.
[SW7700-acl-adv-traffic-of-payserver] rule 1 permit ip source
129.110.1.2 0.0.0.0 destination any
Define the limit to the traffic-of-payserver:
1 Limit the average speed of the traffic-of-payserver to 20M.
[SW7700-Ethernet1/0/1] traffic-limit inbound ip-group
traffic-of-payserver 20

Control Configuration
The Switch 7700 provides several logon and device access measures, mainly
including TELNET access, SNMP access, and HTTP access. The security control over
the access measures is provided with the switches to prevent illegal users from
logging onto and accessing the devices. There are two levels of security controls.
Clear the statistics information reset traffic-statistic { all | ip-group { acl-number |
acl-name } [ rule rule ] | link-group { acl-number |
acl-name } [ rule rule ] }
