Figure 6-18. Port Mirroring Configuration screen
To configure a mirror port, select the Module, and Port from where you want to copy frames in the Source
fields. Then select the Module and Port which receive the copies from the source port in the Destination
fields. The destination (or target) port is where you will connect a monitoring/troubleshooting device such as a
sniffer or an RMON probe.
Note:
You should not 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 to should always support an equal or higher speed than the source port. Also, the
destination port for the mirroring 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 the previous chapter. It is
recommended that you read this, as well as the introductory section in the same chapter entitled
Spanning
Tree Algorithm,
before changing any of the parameters.
STP Parameter Settings
To change the Protocol Parameters:
