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.
The Current Ingress Filtering field shows the current administrative mode of ingress
filtering on the interface.
7. Use Port Priority to specify the default 802.1p priority assigned to untagged packets arriving
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.
To display the MAC Based VLAN page, click Switching
VLAN Advanced MAC Based
VLAN.
To configure a MAC-based VLAN group:
1. Use the MAC Address field to specify a valid MAC Address which is to be bound to a
VLAN ID.0
2. Use VLAN ID to specify a VLAN ID in the range of 1 to 4093.
3. Click ADD to add an entry of MAC Address to VLAN mapping.
4. Click DELETE to delete and entry of MAC Address to VLAN mapping.
