Advanced> VLAN
VLANs: 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. There are 64VLAN supported on this
switch. This switch supports static, port-based VLANs.
A ‘U’ or ‘T’ will be displayed for each port assigned to the VLAN (see Figure 7-21), where ‘U’ stands for untagged and ‘T’ for tagged. If a port is an
untagged member of a VLAN, the VLAN tag will be striped from the frame before it is sent out that port. If the port is a tagged member of a VLAN,
the VLAN tag will stay in the frame when it is sent. A ‘_’ space indicates that the port is not a member of the particular VLAN, and will not get any
traffic for that VLAN. The VLAN tagging option is a standard set by the IEEE to facilitate the spanning of VLANs across multiple switches
(Reference: Appendix C and IEEE Std 802.1Q-1998 Virtual Bridged Local Area Networks).
From this menu, you can create a new VLAN, add new ports to an existing VLAN, remove ports from an existing VLAN or, delete a VLAN.
