8-port Gigabit Ethernet Switch User's Guide • Direction - Allows the specification of which packets will be mirrored based upon whether the packets are flowing into or out of a port, or all packets (both directions). The options are: Ingress - packets flowing into the mirror port, Egress - packets flowing out of the mirror port, and Either - both in to and out of the mirror port. For example, if Ingress is chosen, all packets flowing into the mirror port will be duplicated and forwarded to the target port. Entries • Source Port - Displays the port that will be mirrored. • Direction - Allows the specification of which packets will be mirrored based upon whether the packets are flowing into or out of a port, or all packets (both directions).

Spanning Tree Protocol The Spanning Tree Protocol can be used to detect and disable network loops, and to provide backup links between switches, bridges, or routers. This allows the Switch to interact with other bridging devices (that is, STP compliant switches, bridges, or routers) in your network to ensure that only one route exists between any two stations on the network. For a more detailed description of how to use this protocol, refer to "Spanning Tree Concepts", in Chapter Five. STP Group Configuration Figure 7-37. STP Group Configuration screen The DGS-3308 allows you to configure Spanning Tree Groups that consist of a group of ports that will be handled as though they were a single spanning tree device. Note: This function is available only when the Switch is in IP Routing mode. Items on the screen above include: • Group Name - A name given to identify a given STP group. • Port Members - A list of the ports that belong to a given group. • New - A link to the STP Group Configuration - Add window. • Pointer Icon - A link to the STP Group Configuration - Edit window. • Delete - Click this icon to remove an entry from this table. STP Group Configuration - Add The following window allows you to add an STP Group. Click on the Exit icon to return to the STP Group Configuration menu. 172
