You should have at least a basic knowledge of TCP/IP networking concepts and topology. Related Documentation · Quick Start Guide The Quick Start Guide is designed to help you get up and running right away. · Web Configurator Online Help Embedded web help for descriptions of individual screens and supplementary information. It is recommended you use the web configurator to configure the Switch. · Supporting Disk Refer to the included CD for support documents.

You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to underutilize a high-speed, but more costly, single-port link. However, the more ports you aggregate then the fewer available ports you have. A trunk group is one logical link containing multiple ports. 9. 1. 1 Distribution Criteria The Switch uses a traffic distribution algorithm to balance traffic between trunk members. The Switch allows you to specify what criterion it should use to calculate the most efficient distribution of traffic. The choices are Source MAC Address (SA), Destination MAC Address (DA) or both (SA + DA). The best choice of distribution criteria depends on your specific network environment. 9. 2 Trunk Setting Screen Use this screen to aggregate groups of physical ports into one higher capacity link. Click Trunk Groups in the navigation panel to display the Trunk Setting screen.

Table 15 Trunking: Configuration LABEL Distribution Criterion DESCRIPTION Trunking uses a distribution algorithm to balance traffic between trunk members. Your choices are: · SA (Source MAC Address) · DA (Destination MAC Address) · SA + DA Configure the following settings to create and modify trunk groups. Modify Trunk Group Member Trunk id Port Add Del Trunk 1 . . . Trunk 6 Apply Select the trunk you want to modify or select a trunk id which is not yet configured to create a new trunk group. Click this to add the port to the trunk group you selected in the Trunk id field. Click this to delete the port from the trunk group you selected in the Trunk id field. Trunk Group Member column indicates which ports are members of the trunk group.

Click Mirror in the navigation panel to display the Mirror Setting screen. Use this screen to select a monitor port and specify the traffic flow to be copied to the monitor port. Figure 37 Mirror Setting The following table describes the labels in this screen. Table 16 Mirror Setting LABEL Mode Ingress Mirror Egress Mirror Mirror To DESCRIPTION Select Enabled to turn on port mirroring or select Disabled to turn it off. Select the ports for which you want to monitor the ingress (incoming) traffic. Select the ports for which you want to monitor the egress (outgoing) traffic. The Mirror To (monitor) port is the port you copy the traffic to in order to examine it in more detail without interfering with the traffic flow on the original port(s).
