A tagged based VLAN switch determines the membership of a data frame
by examining the tagged info in the packet received. A four-byte field in the
header is used to identify the VLAN. This VLAN identification indicates
what VLAN the frame belongs to.
The AT-RG213 switch can use VLAN functionality both in upstreaming and
downstream communication.
Configuration Examples
Example 1
Let’s suppose that the AT-RG213 is inserted into a VoIP network where
three Vlan are defined:
• VLAN1 used for VoIP traffic
• VLAN2 used for Video traffic (Multicast Stream)
• VLAN3 used for Internet browsing traffic
VLAN1 is created by default; VLAN2 and VLAN3 have to be created using
the commands:
CREATE VLAN=VLAN2 VID=2
CREATE VLAN=VLAN3 VID=3
VLAN1 configuration
The VoIP and WAN ports must belong to VLAN1.
WAN port must be tagged because it is shared with other VLANs. VoIP port
cannot be tagged. This VLAN is needed to allow VoIP traffic to reach the
network and VoIP port.
ADD VLAN=1 PORT=WAN FRAME=TAGGED
VLAN2 configuration
LAN1, LAN2 and WAN ports must belong to VLAN2. WAN port must be
tagged because it is shared with other VLANs. LAN1 and LAN2 are
untagged ports to allow the Set Top Boxes to receive the packets. This VLAN
is needed to allow Video traffic coming from the network (WAN) to reach
two Set Top Boxes connected to LAN1 and LAN2 ports.
ADD VLAN=2 PORT=LAN1,LAN2 FRAME=UNTAGGED
ADD VLAN=2 PORT=WAN FRAME=TAGGED
VLAN3 configuration
LAN3 and WAN ports must belong to VLAN3. WAN port must be tagged
because it is shared with other VLANs. LAN3 port is untagged to allow the
