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 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 without the login of these device.
The most top-left button is only for Master device(See Fig.3-9). 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_MICROSENS), 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 .
