Subnet VLAN
Subnet VLAN Settings
The subnet VLAN settings are used to create, find or delete a subnet VLAN entry. A subnet VLAN entry is an IP
subnet-based VLAN classification rule. If an untagged or priority-tagged IP packet is received on a port, its source IP
address will be used to match the subnet VLAN entries. If the source IP is in the subnet of an entry, the packet will be
classified to the VLAN defined for this subnet.

VLAN Precedence Settings
The VLAN precedence settings are used to configure VLAN classification precedence on each port. You can specify
the order of MAC-based VLAN classifications and subnet VLAN classifications. If a port’s VLAN classificataion is a
MAC-based precedence, MAC-based VLAN classification will process first. If MAC-based VLAN classification fails, the
subnet VLAN classification will be executed. If a port’s VLAN classification is subnet VLAN precedence, the subnet
VLAN classification will process first. If subnet VLAN classification fails, the MAC-based VLAN classification will be
executed.
