For What Reason Would A Network Administrator Use The Show Interfaces Trunk Command On A Switch?

In order to view the native clan, the network administrator will use the show interfaces truck command on the switch. Today let us discuss the show interfaces and trunk command on a switch in detail.

Now let us know how to configure the trunk mode interfaces on the switches. Normally the trunk mode interfaces are mostly used byo connect between the two switches. We can also connect them between the switch and the host.

The main advantage of the trunk command is that it can able to pass the traffic to the multiple VLANs when we compare it to the access mode interfaces.

Here the untagged traffic will be passed through a clan or by the default VLAN.

And mostly the tagged traffic will be passed to the indicated VLAN. The trunk mode will be able to observe the tagging of 8021.1Q.

Let us take an example to understand this concept in detail. Let us open the command prompt and type enable and press enter after entering the enable the command prompt will be moved into the privileged execution mode.

And now run the show interfaces status on it. Here it will display the configuration which is currently present.

Here the current mode will be indicated by the letter ‘A’. Here A represents the access and the letter T will represent the trunk and the letter G will represent for general.

And when we run the interface range x, where x represents the interface range in order to select.

And when we want to convert this into trunk mode, we use the switch port mode trunk and simply type the exit command.

And to confirm if the changes have been taken place or nor we simply run the show interface status and then press enter.

Here we can see the change in the mode that has taken place.

We can also able to see all the associated VLANs along with their I’d number.

Let us take an example to understand the main difference between the trunk port and the access port.

Let say we have four different types of the VLANs such as VLAN 1,2,3,4 where each is connected to a switch. And assume that these switches are not connected to each other. Hence here we can say that the port that is connected to the computer to the switch will be called the access port. Here the access port can only able to allow only single VLAN at a single time. So that all the VLANs are not able to communicate with each other at a single time.

To resolve this issue and make all the VLANs communicate with each other simultaneously we use the command called the trunk command. Here the trunk command will allow multiple VLANs to traverse at a single time.

The link that is connecting all these VLANs is then connected as a single link and allows multiple VLANs to communicate with each other.
