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
become 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 wit-
hout the login of these device.
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_ES-2126+), other-
wise 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 tel-
net/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 .
