Gigabit Ethernet Switch User's Guide Configure Port Mirroring The Port Mirroring Configuration screen allows you to copy frames transmitted and received on a port and redirect the copies to another port. You can attach a monitoring device to the mirrored port, such as a sniffer or an RMON probe, to view details about the packets passing through the first port. This is useful for network monitoring and troubleshooting purposes. Choose Configure Port Mirroring on the System Configuration menu to access the Port Mirroring Configuration screen: Figure 6-15. Port Mirroring Configuration 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. When you are finished, change the Status to Enabled and then press APPLY to let your changes take effect. 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 System Configuration menu. The following Configure Spanning Tree Protocol menu will be displayed: 38
