Trunk Port
Downlink port 1/1 and uplink port 1/5 of Switch1 and Switch 2
Multi-to-One VLAN-
translation
Downlink port 1/1 of Switch1 and Switch2
Configuration procedure is as follows:
Switch1, Switch2:
switch(Config)# vlan 1-3;100
switch(Config-Ethernet1/1)#switchport mode trunk
switch(Config-Ethernet1/1)# vlan-translation n-to-1 1-3 to 100
switch(Config)#interface ethernet 1/5
switch(Config-Ethernet1/5)#switchport mode trunk
switch(Config-Ethernet1/5)#exit
18.5.4 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.
18.6 Dynamic VLAN Configuration
18.6.1 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 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
