2.5.7. VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows
you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN
members. Basically, creating a VLAN from a switch is logically equivalent to reconnecting a group
of network devices to another Layer 2 switch. However, all the network devices are still plugged
into the same switch physically.
The NP2624M switch supports port-based, 802.1Q (tagged-based) and protocol-base VLAN in web
management page. In the default configuration, VLAN support is disabled.
Support Port-based VLAN
Packets can only be broadcast among members of the same VLAN group. Note all unselected ports
are treated as belonging to another single VLAN. If the port-based VLAN is enabled, the VLAN-
tagging is ignored.
