Which step should be performed first when deleting a VLAN that has member switch ports?
Answer: When someone wants to delete the active VLAN it is needed that the recently assigned ports as a VLAN member need to be reassigned. The port which is a VLAN member which is deleted will become unstable.
VLAN description and its types
VLAN a virtual LAN is the subnetwork that makes the device collection jointed on different or separate local area networks (LANs)the LAN is the connection of the devices such as computers which can communicate with each other and with servers in local areas.
VLAN is useful for the administrator because they can use the single switch partitions to compare their functionality and the security of the system rather than using the new cables and making the changes in the infrastructure of the network. For the management of the traffic over the network VLAN is used by the business on a larger scale by the partition of the switch.
For the devices which communicate most often VLAN is important because and the performance becomes improve. The security protection is also provided by VLAN to a large network with the control on the devices which can access each other. The VLAN is a logical connection rather than a physical one’s which is kind of flexible.
Types of VLAN:
Types of the VLANs are discussed in the following section:
Protocol-based VLAN:
The traffic control can be done by the protocol-based VLAN. The switch will move the traffic based on traffic protocol.
Static based VLAN:
It is the port-based VLAN and it required the network administrator which can allocate the ports on the network switch with the virtual network.
Dynamic based VLAN:
The network memberships which are based on the characteristics of the device are defined by the network administrator and it is allowed by dynamic-based VLAN rather than the location of the switch port.
Working on the VLAN
When the workstation sends the data toward the bridge of LAN, it is tagged with the VLAN identifies which shows the VLAN of the incoming data, the process is known as the explicit tagging. With the implicit tagging is almost impossible to find the VLAN of coming data. in implicit tagging the data is not tagged with the VLAN identifier but from the VLAN from where the data came is identified with port numbers.
Tagging depends on the ports, the media access control source field the network address of the source, or the other filed combinations, VLAN is categorized with the help of the used method to do the tagging with methods the bridge required the database with the new version and also had the map of the fields used and the VLAN.
IF the tagging is based on the port then the database has the information related to that port VLAN. And the database is called the filtering database. The bridges need to make sure that the information on the LAN is the same on each database, and according to the LAN operation, the bridges define where the data need to go.
