Figure 6-16. Configure Port Mirroring screen
To configure a mirror port, select the port from where you want to copy frames in the Source Port field. Then select the port
which receives the copies from the source port in the Target Port field. The target port is where you will connect a
monitoring/troubleshooting device such as a sniffer or an RMON probe.
Note: You cannot mirror a fast port onto a slower port. For example, if you try to mirror the traffic from a 100 Mbps port
onto a 10 Mbps port, this can cause throughput problems. The port you are copying frames from should always
support an equal or lower speed than the port to which you are sending the copies. Also, the target port cannot be a
member of a trunk group.
Configure Spanning Tree Protocol
The Spanning Tree Algorithm Parameters can be used for creating alternative paths in your network. The Protocol
Parameters allow you to change the behind the scene parameters of the Spanning Tree Algorithm at the bridge level. The
parameters for this section have been fully explained in Chapter 5’s Switch Management Concepts, see STA Operation
Levels: On the Bridge level, and User-Changeable Parameters. It is recommended that you read these sections, as well
as the introductory section in the same chapter entitled Spanning Tree Algorithm before changing any of the
parameters.

To change the Protocol Parameters:
1. Choose Configure Spanning Tree Protocol from the Configuration menu. The following Configure
Spanning Tree Protocol menu will be displayed:
