Vlan Screen - ZyXEL Communications GS1200 SERIES User Manual

A broadcast frame (or a multicast frame for a multicast group that is known by the system) is
duplicated only on ports that are members of the VID (except the ingress port itself), thus confining
the broadcast to a specific domain.
8.1.1.2 Port-based VLANs
Port-based VLANs are VLANs where the packet forwarding decision is based on its associated port.
A port can only belong to one port-based VLAN. Subscriber ports in different port-based VLANs
cannot talk to each other.
Port-based VLANs are specific only to the Switch on which they were created.
Note: When you activate port-based VLAN, the Switch uses a default VLAN ID of 1. You
cannot change it.

8.2 VLAN Screen

Use this screen to view and configure VLAN settings for the Switch. Click VLAN in the navigation
panel to open the following screen.
The VLAN screen changes depending on whether you choose IEEE 802.1Q VLAN or Port-Based
VLAN in this screen.
Note: You could block yourself (and all others) from managing the Switch if you remove
all ports from the management VLAN (VLAN 1 by default).
Make sure the port through which you connect your computer and access the
Switch's web configurator is in VLAN 1.
