VLAN Guidelines
Plan the VLAN layout first. The creation of a map of the network, showing which devices
to associate with which VLAN, is strongly recommended prior to configuration.
Generally speaking, ports connected to end devices will be configured as
Normal/Untagged and given a VLAN ID#.
Ports connected to other VIA switches will typically be set as Uplink/Tagged, so multiple
VLANs may be forwarded between switches, or when a VLAN must be forwarded
through an intermediate switch (where that VLAN is not in use) on to a third switch
beyond. It is possible to set the ports to Normal/Untagged, and given and VLAN ID#, in
cases where it’s desirable to pass only one VLAN between swtiches.
It is strongly recommended that the ports used to connect separate switches should be
set to matching configurations.
When configuring VLANs, remember that each switch must be uniquely identified on
each VLAN in use on that switch. By default, only the management VLAN is
automatically assigned an IP and subnet mask. All other VLANs default to a null IP
address value (0.0.0.0). Use the Network Configuration options available from the VLAN
configuration screen to configure the desired IP settings for each VLAN.
