CONFIGURING IP SUBNET-BASED VLANS

Use the IP Subnet-based VLAN Membership Configuration page to map

untagged ingress frames to a specified VLAN if the source address is found

in the IP subnet-to-VLAN mapping table.

When using port-based classification, all untagged frames received by a

port are classified as belonging to the VLAN whose VID (PVID) is

associated with that port.

When IP subnet-based VLAN classification is enabled, the source address of

untagged ingress frames are checked against the IP subnet-to-VLAN

mapping table. If an entry is found for that subnet, these frames are

assigned to the VLAN indicated in the entry. If no IP subnet is matched, the

untagged frames are classified as belonging to the receiving port’s VLAN ID

(PVID).

COMMAND USAGE

◆ Each IP subnet can be mapped to only one VLAN ID. An IP subnet

consists of an IP address and a mask. The specified VLAN need not be

an existing VLAN.
