170CHAPTER 7: QOS/ OPERATION

For a 48-port module, the monitoring port and the monitored port must all be at the ports 1-24 or ports 25-48, on which only one mirroring group can be configured in one direction.

E3/0/1E3/0/8

Server

E3/0/2

To create this configuration:

Define a mirroring group, with monitoring port being Ethernet0/8:

[SW7750]mirroring-group 1 inbound ethernet3/0/1 ethernet3/0/2

mirrored-to ethernet3/0/8

[SW7750]mirroring-group 2 outbound ethernet3/0/1 ethernet3/0/2

mirrored-to ethernet3/0/8

Priority Relabeling Configuration Example

In this example, ef labels are appended on packets sent between 8:00 and 18:00 each day from PC1 (IP 1.0.0.2), as priority labeling reference for the upper-layer device.

To create this configuration:

1Define the time range.

Define the time range between 8:00 and 18:00.

[SW7750]time-range 3com 8:00 to 18:00 daily

2Define traffic rules for PC packets.

Enter the number-based basic ACL and select the ACL 2000.

[SW7750]acl number 2000

Define traffic classification rules for PC1 packets.
