Only the commands concerning QoS/ACL configuration are listed here. To create this configuration:

1Define outbound traffic for the wage server.

Enter name-based advanced ACL view using the traffic-of-payserver.

[SW7750]aclname traffic-of-payserver advanced

Define the traffic-of-payserver rule in the advanced ACL.

[SW7750-acl-adv-traffic-of-payserver]rule 1 permit ip source

129.110.1.2 0.0.0.0 destination any

2Set traffic limit for the wage server.

Enter QoS view.

[SW7750-GigabitEthernet7/0/1]qos

[SW7750-qosb-GigabitEthernet7/0/1]

Limit average outbound traffic of the wage server to 20 Mbps and label over-threshold packets with priority level 4.

[SW7750-qosb-GigabitEthernet7/0/1]traffic-limit inbound ip-group

traffic-of-payserver 20 exceed remark-dscp 4

Limit inbound traffic of the wage server from the port GigabitEthernet7/0/1 to 20 Mbps.

[SW7750-qosb-GigabitEthernet7/0/1]line-rate 20

Port Mirroring

This configuration uses one server to monitor the packets of two PCs. One PC is accessed from the port E3/0/1 and the other from the port E3/0/2. The server is connected to the port Ethernet3/0/8.

The monitoring port and the monitored ports must be on the same I/O module.

For a non-48-port module, only one mirroring group can be configured in one direction. For example, you can only configure one mirroring group for the inbound packets on one module. The configuration will fail if you configure a second mirroring group. The same restriction applies to outbound packets.
