Switch> VLAN Page A Virtual Local Area Network (VLAN) is a means to electronically separate ports on the same switch from a single broadcast domain into separate broadcast domains. By using VLAN, users can group by logical function instead of physical location. The VLAN Table shows two types of VLAN and other information: · · · · · IEEE 802. 1Q VLAN (Tagged VLAN) Port-based VLAN ID: Description: Member: The port number on the switch User-definable Indicates which port/s belong to a VLAN group Page 12 of 12 Switch> VLAN> Port-based VLAN Depending on your model, there are up to 26 port-based VLAN groups supported on this switch, any one port can belong to different VLAN groups. The default VLAN group port-based VLAN that have all ports belonging to VLAN 1. Change members · · · · · · · · Click a VLAN ID as shown in Figure 5-16 Click to select port/s for VLAN members Click Apply to activate the new setting Click Add VLAN. Enter a description for this VLAN Click to select port/s for VLAN members or click Set all to select all ports Click Clear all to unselect all ports Click Apply to activate the new setting Add VLAN Delete VLAN · · · Click Delete VLAN Click to select a VLAN ID Click Apply to confirm delete this VLAN Switch> VLAN> IEEE802. 1Q Tag VLAN Depending on your model switch there are up to 64 static Tag VLAN groups supported on your switch. The VLAN tagging option is a standard set by the IEEE to facilitate the spanning of VLANs across multiple switches (Reference: Appendix A and IEEE Std 802. 1Q-1998 Virtual Bridged Local Area Networks). Click to select IEEE802. 1Q VLAN as shown in Figure 2-16. The following screen pops up to confirm this change. Figure 5-3. Switch> VLAN Setting> Tag VLAN All ports are set belonging to VLAN 1 by default, all untagged. From the page, you can create a new VLAN, add new ports to an existing VLAN, remove ports from an existing VLAN or, delete a VLAN. Page 13 of 13 Add a port to a VLAN Group · · · · · Under the VLAN ID drop down menu, select the VLAN you want to edit. Click the box below the port number so that a `T' (tagged) or `U' (untagged) appears. Click the box again until a blank box appears. This will remove VLAN membership from the port. Click Apply. Remove a port from a VLAN Group Note: The default PVID of all ports is 1; therefore, you cannot remove any ports for the default Tag VLAN. [. . . ] If an untagged packet enters Port 4, switch will tag it with a VLAN tag value 20. The packet will have access to Port 5 and Port 6. The outgoing packet will be stripped away its tag becoming an untagged packet as it leaves Port 6. For Port 5, the outgoing packet will leave as a tagged packet with a VLAN tag value 20. Page 21 of 21 APPENDIX C: Port-based VLAN Port-based VLAN will help efficiently confine the broadcast traffic to the switch ports. [. . . ]
