16.5.4 Multi-to-One VLAN Translation Troubleshooting
Do not be used with Dot1q-tunnel at the same time.
Do not be used with VLAN-translation at the same time.
The same MAC address should not exist in the original and the translated VLAN.
Check whether the hardware resource of the chip is able to ensure all clients to work normally.
Limit learning of MAC address may affect Multi-to-One VLAN Translation.
Multi-to-One VLAN Translation should be enabled after MAC learning.
16.6 Dynamic VLAN Configuration
16.6.1 Introduction to Dynamic VLAN
The dynamic VLAN is named corresponding to the static VLAN (namely the port based VLAN).
Dynamic VLAN supported by the switch includes MAC-based VLAN and Protocol-based
VLAN. Detailed description is as follows:
The MAC-based VLAN division is based on the MAC address of each host, namely 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 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.
Notice: It can not be configured the rule at the same time for the protocol number last 4 bits,
for example: protocol number 2048 and 1536 only one of them can be configured.
16.6.2 Dynamic VLAN Configuration
Dynamic VLAN Configuration Task Sequence:
1. Configure the MAC-based VLAN function on the port
2. Set the VLAN to MAC VLAN
