Static Vlan Configuration - Interlogix GE-DS-242-PoE User Manual

Chapter 4: Web-Based Management
packets are also assigned a PVID, but the PVID is not used to make packet
forwarding decisions, the VID is.
Tag-aware switches must keep a table to relate PVID within the switch to VID on
the network. The switch will compare the VID of a packet to be transmitted to the
VID of the port that is to transmit the packet. If the two VID are different the
switch will drop the packet. Because of the existence of the PVID for untagged
packets and the VID for tagged packets, tag-aware and tag-unaware network
devices can coexist on the same network.
A switch port can have only one PVID, but can have as many VID as the switch
has memory in its VLAN table to store them.
Because some devices on a network may be tag-unaware, a decision must be
made at each port on a tag-aware device before packets are transmitted - should
the packet to be transmitted have a tag or not? If the transmitting port is
connected to a tag-unaware device, the packet should be untagged. If the
transmitting port is connected to a tag-aware device, the packet should be
tagged.
Default VLANs
The Switch initially configures one VLAN, VID = 1, called "default." The factory
default setting assigns all ports on the Switch to the "default". As new VLAN are
configured in Port-based mode, their respective member ports are removed from
the "default."
VLAN and Link Aggregation Groups
In order to use VLAN segmentation in conjunction with port link aggregation
groups, you can first set the port link aggregation group(s), and then you may
configure VLAN settings. If you wish to change the port link aggregation grouping
with VLAN already in place, you will not need to reconfigure the VLAN settings
after changing the port link aggregation group settings. VLAN settings will
automatically change in conjunction with the change of the port link aggregation
group settings.

Static 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 of reconnecting a group of network devices to
another Layer 2 switch. However, all the network devices are still plug into the
same switch physically.
