
This refers to VLAN partitions by the source MAC address of the packet.

This refers to VLAN partitions by the source IP subnet of the packet.

This refers to VLAN partitions by the protocol type carried in the packet received by the
interface and assigning different VLAN IDs for packets. The protocol VLAN is defined by the
protocol profile. One interface can be associated with multiple protocol profiles. After an
interface is associated with protocol VLANs, it will process packets as below:

Tag to the

VLAN partitions by MAC address
When an interface receives an untagged packet, it matches the source MAC address
–
of the packet with the VLAN MAC addresses. If they are the same, the match is
successful. In this case, the interface adds the VLAN ID specified by VLAN MAC
addresses, and forwards the packet. If they are different, the interface continues to
match the packet with the IP address-based VLAN and interface-based VLAN in
descending order.
When a tagged packet reaches an interface, if its VLAN ID is in the VLAN ID list
–
allowed to pass by the interface, the interface receives it. Otherwise, the interface
discards it.
VLAN partitions by IP subnet
When an interface receives an untagged packet, it determines the VLAN of the
–
packet by the source IP subnet of the packet, and then transmits the packet in the
specified VLAN.
When a tagged packet reaches an interface, if its VLAN ID is in the VLAN ID list
–
allowed to pass by the interface, the interface receives it. Otherwise, the interface
discards it.
VLAN partitions by protocol
After receiving an untagged packet from an interface, the device adds the VLAN Tag of
the protocol VLAN defined by the protocol profile if the packet matches the protocol
profile, or adds the default VLAN Tag if the packet does not match the protocol profile.
When receiving a tagged packet from an interface, the device receives the packet if the
VLAN ID is in the list of VLANs of which packets are allowed to pass by the interface,

Tagged packets

If the VLAN ID of the
packet is included in the
list of VLANs of which
packets are allowed to
pass by the interface, the
interface will receive the
packet.
 If the VLAN ID of the
packet is excluded from
the list of VLANs of
which packets are
allowed to pass by the
interface, the interface
will discard the packet.


If the VLAN ID of the
packet of the packet is
equal to the Native VLAN
ID, the interface will
remove the Tag and send
the packet.
 If the VLAN ID of the
packet is not equal to the
Native VLAN ID and the
interface allows packets of
the VLAN to pass, the
interface will keep the
original Tag and send the
packet.
