inherently provide a high level of network security since traffic must pass through a
configured Layer 3 link to reach a different VLAN.
This switch supports the following VLAN features:
• Up to 255 VLANs based on the IEEE 802.1Q standard
• Distributed VLAN learning across multiple switches using explicit or implicit tagging and
GVRP protocol
• Port overlapping, allowing a port to participate in multiple VLANs
• End stations can belong to multiple VLANs
• Passing traffic between VLAN-aware and VLAN-unaware devices
• Priority tagging
Note:
The switch allows 255 user-manageable VLANs. One extra, unmanageable VLAN
(VLAN ID 4093) is maintained for switch clustering.
Assigning Ports to VLANs
Before enabling VLANs for the switch, you must first assign each port to the VLAN
group(s) in which it will participate. By default all ports are assigned to VLAN 1 as
untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more
VLANs, and any intermediate network devices or the host at the other end of the
connection supports VLANs. Then assign ports on the other VLAN-aware network
devices along the path that will carry this traffic to the same VLAN(s), either manually or
dynamically using GVRP. However, if you want a port on this switch to participate in one
or more VLANs, but none of the intermediate network devices nor the host at the other
end of the connection supports VLANs, then you should add this port to the VLAN as an
untagged port.
Note: VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network
interconnection devices, but the VLAN tags should be stripped off before passing it on
to any end-node host that does not support VLAN tagging.
VLAN Classification – When the switch receives a frame, it classifies the frame in one of
two ways. If the frame is untagged, the switch assigns the frame to an associated VLAN
(based on the default VLAN ID of the receiving port). But if the frame is tagged, the switch
uses the tagged VLAN ID to identify the port broadcast domain of the frame.
