switch(Config-Ethernet1/5)#exit
20.5.4 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.
 Limiting learning of MAC address may affect Multi-to-One VLAN Translation.
 Multi-to-One VLAN Translation should be enabled after MAC learning.
20.6 Dynamic VLAN Configuration
20.6.1 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, IP-subnet-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 moving from a physical location to
another. We can see the greatest advantage of this VLAN division is that the VLAN does not
have to be re-configured when the user physical location changes, meaning shifting from one
switch to another, which is because it is user based, not switch port based.
