Configuration

VLAN-translation

Configuration procedure is as follows:

Switch1、Switch2:

switch(Config)# vlan 1-3;100

switch(Config-Ethernet1/0/1)#switchport mode trunk

switch(Config-Ethernet1/0/1)# vlan-translation n-to-1 1-3 to 100

switch(Config)#interface ethernet 1/0/5

switch(Config-Ethernet1/0/5)#switchport mode trunk

switch(Config-Ethernet1/0/5)#exit

2.19.4

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.

Super VLAN

2.20.1

Introduction to Super VLAN

Super VLAN, also called VLAN aggregation, we introduce the notion of super VLAN

and sub VLAN. One or more sub VLANs belong to a super VLAN, and sub VLAN does not

occupy an absolute subnet segment any more. However, in the same super VLAN,

whether host belongs to any sub VLAN, its IP address is within the subnet segment

associated with super VLAN.

In LanSwitch network, VLAN technique is applied widely for advantages (flexible

control of broadcast domain and deploy convenience). However, in generic layer-3 switch,

it implements communication between broadcast domains through a method that a VLAN

correspond to a layer-3 interface, it results in IP address waste.

For example, VLAN division of device is shown in the figure.
