Difference between mux vlan and super vlan

Hello guys, in this post, I’d like to share you the difference between the super vlan and mux vlan.

 

Super vlan, also called aggregate vlan, is used to partition a broadcast domain on a physical network into multiple VLANs (sub-VLANs) and aggregates them into a single logical VLAN (super-VLAN). The sub-VLANs are addressed from the same IP subnet and share a default gateway address, thereby reducing the number of IP addresses required on the network.

In a simple word, super vlan is used to save IP address.

 

Mux vlan contains two main part, principle vlan and subordinate vlan which sperate into two parts, separate vlan and group vlan. And they can be described as the table below:


MUX VLAN

VLAN Type

Associated    Port

Access    Authority

Principal VLAN

-

Principal port

A principal   port can communicate with all ports in a MUX VLAN.

Subordinate   VLAN

Separate VLAN

Separate port

A separate   port can communicate only with a principal port and is isolated from other   types of ports.

Each separate   VLAN must be bound to a principal VLAN.

Group VLAN

Group port

A group port   can communicate with a principal port and the other ports in the same group,   but cannot communicate with ports in other groups or a separate port.

Each group   VLAN must be bound to a principal VLAN.

 

Unlike the super vlan, mux vlan cannot save IP addresses. From the table above, we could learn that mux vlan is used to sperate traffic between terminals. Commonly, if we use the vlan to sperate the traffic between hosts, it will cost a lot of vlan number, and the total number of vlan is fixed, which is 4096, mux vlan could help us to do this task without wasting so many vlans.

we often mix them up for not using them frequently.
