every host with a MAC address will be assigned to certain VLAN. By the means, the
network user will maintain his membership in his belonging VLAN when moves from a
physical location to another. As we can see the greatest advantage of this VLAN division
is that the VLAN does not have to be re-configured when the user physic location change,
namely shift from one switch to another, which is because it is user based, not switch port
based
The IP subnet based VLAN is divided according to the source IP address and its
subnet mask of every host. It assigns corresponding VLAN ID to the data packet
according to the subnet segment, leading the data packet to specified VLAN. Its
advantage is the same as that of the MAC-based VLAN: the user does not have to
change configuration when relocated.
The VLAN is divided by the network layer protocol, assigning different protocol to
different VLANs. This is very attractive to the network administrators who wish to
organize the user by applications and services. Moreover the user can move freely within
the network while maintaining his membership. Advantage of this method enables user to
change physical position without changing their VLAN residing configuration, while the
VLAN can be divided by types of protocols which is important to the network
administrators. Further, this method has no need of added frame label to identify the
VLAN which reduce the network traffic.
5.5.2 Dynamic VLAN Configuration
5.5.2.1 Dynamic VLAN Configuration Task Sequence
1. Configure the MAC-based VLAN function on the port
2. Configure the correspondence between the MAC address and the VLAN
3. Configure the IP-subnet-based VLAN function on the port
4. Configure the correspondence between the IP subnet and the VLAN
5. Configure the correspondence between the Protocols and the VLAN
6. Adjust the priority of the dynamic VLAN
1. Configure the MAC-based VLAN function on the port
2. Configure the correspondence between the MAC address and the VLAN
