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_GSW-2
494
), 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 .
