56.12.1 Subnet-based VLAN Command Examples
This example configures a subnet-based VLAN ( subnet1VLAN ) with priority 6 and a VID of 200 for traffic
received from IP subnet 172.16.37.1/24 .
56.13 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 OLT 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 ports 1, 2, and 3 will be grouped together, and all upstream Apple Talk
traffic from ports 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.
