9.7 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.
