    QUICKSTART GUIDE 7 Hubs and Switches Two of the major Ethernet LAN components are "hubs" and "switches." There are many advantages of a switch over a hub. Hubs just transfer information from one port to all other ports. Since a hub has no way of handling media contention, collisions can occur requiring all segments connected to a hub to work in a half duplex mode.

  • Page 50 QUICKSTART GUIDE You will notice below, that the status of the VLAN named GOOSE2 is displayed as Pending. To activate VLAN 2 proceed as follows. Select Status. Once in the Status menu, set the VLAN ID to 2 and the VLAN status to start.
  • Page 51 QUICKSTART GUIDE Select OK to start VLAN 2. You will notice that VLAN 2 is now active, and ports 21 and 23 are part of this VLAN. Ports 21 and 23 have been removed from the default tagged based VLAN1. You can add ports 21 and 23 back into the default tagged based VLAN 1 if you wish, such that they are part of both VLAN 1 and VLAN 2.
  • Page 52 QUICKSTART GUIDE Add ports 21 and 23 to tagged based VLAN 1 by checking the corresponding boxes. SAVE Select the save icon at the top of the screen. Select OK to return to the main tag VLAN menu. Note that ports 21 and 23 are now part of both VLAN1 and VLAN 2. You have now completed the exercise.
