170 CHAPTER 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.
Figure 41 Port Mirroring Configuration
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.
Figure 42 Priority Relabeling Configuration
To create this configuration:
1 Define the time range.
Define the time range between 8:00 and 18:00.
[SW7750]time-range 3com 8:00 to 18:00 daily
2 Define 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.
