3-1-6. Virtual Stack
 
Function name: 
Virtual Stack
Function description:
Virtual Stack Management(VSM) is the group management function. Through 
the proper configuration of this function, switches in the same LAN will be 
grouped automatically. And among these switch, one switch will be a master 
machine, and the others in this group will become the slave devices. 
VSM offers a simple centralized management function. It is not necessary to 
remember the address of all devices; manager is capable of managing the 
network with knowing the address of the Master machine. Instead of SNMP or 
Telnet UI, VSM is only available in Web UI. While one switch becomes the 
Master, two rows of buttons for group device will appear on the top of its Web 
UI. By pressing these buttons, user will be allowed to connect the Web UI of 
the devices of the group in the same window without the login of these devices. 
The most top-left button is only for Master Device. The background color of the 
button you press will be changed to represent that the device is under your 
management. 
Note: It will remove the grouping temporarily in case that you login the switch
via the console.
The device of the group will be shown as station address (the last number of 
IP Address) + device name on the button, otherwise it will show ” ---- “ if no 
corresponding device exists. 
Once the devices join the group successfully, then they are merely able to be 
managed via Master device, and user will fail to manage them via 
telnet/console/web individually. 
Up to 16 devices can be grouped for VSM; however, only one Master is 
allowed to exist in each group. For Master redundancy, user may configure 
more than two devices as Master device; however, the Master device with the 
smaller MAC value will be the Master one. All of these 16 devices can 
become Master device and back up with each other.
