Mac Based Vlan - NETGEAR GSM7212P User Manual

Use Acceptable Frame Types to specify the types of frames that may be received on this
5.
port. The options are 'VLAN only' and 'Admit All':
When set to 'VLAN only', untagged frames or priority tagged frames received on this
•
port are discarded.
When set to 'Admit All', untagged frames or priority tagged frames received on this
•
port are accepted and assigned the value of the Port VLAN ID for this port. With either
option, VLAN tagged frames are forwarded in accordance to the 802.1Q VLAN
specification.
6. Ingress Filtering:
When enabled, the frame is discarded if this port is not a member of the VLAN with
•
which this frame is associated. In a tagged frame, the VLAN is identified by the VLAN
ID in the tag. In an untagged frame, the VLAN is the Port VLAN ID specified for the
port that received this frame.
When disabled, all frames are forwarded in accordance with the 802.1Q VLAN bridge
•
specification. The factory default is disabled.
Use Port Priority to specify the default 802.1p priority assigned to untagged packets arriving
7.
at the port. The possible value is from 0 to 7.

MAC Based VLAN

The MAC Based VLAN feature allows incoming untagged packets to be assigned to a VLAN
and thus classify traffic based on the source MAC address of the packet.
A MAC to VLAN mapping is defined by configuring an entry in the MAC to VLAN table. An
entry is specified via a source MAC address and the desired VLAN ID. The MAC to VLAN
configurations are shared across all ports of the device (i.e. there is a system wide table that
has MAC address to VLAN ID mappings).
When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to
VLAN table, the source MAC address of the packet is looked up. If an entry is found the
corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it will
maintain this value, otherwise the priority will be set to zero. The assigned VLAN ID is verified
against the VLAN table, if the VLAN is valid ingress processing on the packet continues,
otherwise the packet is dropped. This implies that the user is allowed to configure a MAC
address mapping to a VLAN that has not been created on the system.
