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 
addresses 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 (e.g. 196_GEL2-SW8), 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 the 
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.
