Chapter 9 VLAN Table 25 Advanced Application > VLAN > VLAN Port Setting > Subnet Based VLAN Setup LABEL DESCRIPTION Index This is the index number identifying this subnet based VLAN. Click on any of these numbers to edit an existing subnet based VLAN. Active This field shows whether the subnet based VLAN is active or not. Name This field shows the name the subnet based VLAN. IP This field shows the IP address of the subnet for this subnet based VLAN. Mask-Bits This field shows the subnet mask in bit number format for this subnet based VLAN. VID This field shows the VLAN ID of the frames which belong to this subnet based VLAN. Priority This field shows the priority which is assigned to frames belonging to this subnet based VLAN. Delete Click this to delete the subnet based VLANs which you marked for deletion. Cancel Click Cancel to begin configuring this screen afresh. 9.8 Protocol Based VLANs Protocol based VLANs allow you to group traffic into logical VLANs based on the protocol you specify. When an upstream frame is received on a port (configured for a protocol based VLAN), the Switch checks if a tag is added already and its protocol. The untagged packets of the same protocol are then placed in the same protocol based VLAN. One advantage of using protocol based VLANs is that priority can be assigned to traffic of the same protocol. Note: Protocol based VLAN applies to un-tagged packets and is applicable only when you use IEEE 802.1Q tagged VLAN. For example, ports 1, 2, 3 and 4 belong to static VLAN 100, and ports 4, 5, 6, 7 belong to static VLAN 120. You can configure a protocol based VLAN A with priority 3 for ARP traffic received on port 1, 2 and 3. You can also have a protocol based VLAN B with priority 2 for Apple Talk traffic received on port 6 and 7. All upstream ARP traffic from port 1, 2 and 3 will be grouped together, and all upstream Apple Talk traffic from port 6 and 7 will be in another group and have higher priority than ARP traffic when they go through the uplink port to a backbone switch C.

Protocol Based VLANs
Protocol based VLANs allow you to group traffic into logical VLANs based on the protocol you
specify. When an upstream frame is received on a port (configured for a protocol based VLAN), the
Switch checks if a tag is added already and its protocol. The untagged packets of the same protocol
are then placed in the same protocol based VLAN. One advantage of using protocol based VLANs is
that priority can be assigned to traffic of the same protocol.
Note: Protocol based VLAN applies to un-tagged packets and is applicable only when you
use IEEE 802.1Q tagged VLAN.
For example, ports 1, 2, 3 and 4 belong to static VLAN 100, and ports 4, 5, 6, 7 belong to static
VLAN 120. You can configure a protocol based VLAN A with priority 3 for ARP traffic received on port
1, 2 and 3. You can also have a protocol based VLAN B with priority 2 for Apple Talk traffic received
on port 6 and 7. All upstream ARP traffic from port 1, 2 and 3 will be grouped together, and all
upstream Apple Talk traffic from port 6 and 7 will be in another group and have higher priority than
ARP traffic when they go through the uplink port to a backbone switch C.
