The native Vlan can automatically receive all untagged frames that are present
Today let us discuss the native VLANs in detail. Normally there are two types of VLANs that are present they are called the native Vlan and the other one is called the default VLAN.
Now let us discuss each one of them in detail. Here the native Vlan will be one of the confusing topics among all the VLANs that are present so let us know about native Vlan first.
Now let us actually know why do we need the native Vlan what actually the use of this native Vlan in detail.
Before we discuss the native Vlan, first we need to have an idea about the term VLAN. The default VLAN can be the first Vlan that is present on Every switch.
Here we will assign the access port to that particular VLAN can call as the collection of the VLAN. Normally the access port will belong to the VLAN 1.
Now let us know the two most important things that we need to remember in default VLAN. The fact is that we are not able to change the default VLAN, and we are not able to delete the default VLAN.
As we said earlier the default setting of the switches will be Vlan 1, we will never use the standard data VLAN.
Now let us know about the native VLAN in detail. The native VLAN is the one that can be traversed to demand the trunk without the VLAN tag.The native VLAN is the same as the management VLAN.
Default the native Vlan will be Vlan 1. Here we can change the number to any number like 2,90, etc.
This will be taken place on a single trunk port that is present. The native VLAN has the configuration of per trunk and per switch configuration. We can change the native Vlan to the different types of VLAN other than the VLAN 1. We can use any number for the VLAN. Because the native Vlan on the cisco switch will allow the possible Vlan that has the hopping attack.
The native VLAN will not be used by many people. Here the native VLAN will have the same on both ends of the trunk that is present. Or else the trunk will not able to work properly.
But we might have a question about what actually the native Vlan is now let us know that in detail. It is mainly created for the backward compatibility that is given to the old devices.
It is mainly used to carry the special control management protocol. which will be taken place. One example of this such as the CDP. The term CDP stands for the cisco discovery protocol. If native VLAN is present then we do not need any type of VLAN tag in order to cross over the trunk.
Here the main goal of the native VLAN is that it can able to hold the information throughout the switch even if any trunk is not present.
