3-10. VLAN (Virtual Local Area Network)
The GSM Series switches support both 802.1q Tagged based VLAN’s and Port-based VLAN’s.
VLAN’s are used to logically separate your network into smaller more defined networks. VLAN’s
help to reduce broadcast traffic across your network as all broadcast traffic will be limited to the
VLAN group in which it belongs. A typical example of where a VLAN could be used is in a school
environment where the teacher and student networks must be kept separate. The switch
supports up to 256 active VLAN entries and a VLAN ID ranging from 1 – 4096.

VLAN group 2 these ports will not be able to communicate with each other. Ports
that belong to the same group can communicate. Ports can also belong to
multiple groups for example, allowing an internet connection to be shared among
