5.7 Virtual
Stack
Function name:
Virtual Stack
Function description:
Virtual Stack Management (VSM) is the group management function. VSM configuration
automatically groups switches in the same LAN. One switch among the group will be the master
device, and the others will become the slave devices.
VSM offers a simple centralized management function. It is not necessary to remember the address
of all devices, because the manager is capable of managing the network with the address of the
Master device. VSM is only available in Web UI. While one switch become the Master, two rows of
buttons for the group device will appear on the top of the Web UI. You can use these buttons to
connect to the Web UI of the devices of the group without logging into these devices.
The top-left button is only for Master device (See Figure 3-9). The background color of the button
you press will be changed to represent that the device is under your management.
Note
: It If you login via the console, the grouping will be removed temporarily.
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). If no corresponding device exisits, ” ---- “ will be
displayed.
Once the devices successfully join the group, they can be managed via the Master device and
cannot be managed 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, you may configure more than two devices as Master device, however,
the Master device with the smaller MAC value will be the Master. All of these 16 devices can
become the Master device and back up with each other .
Virtual Stack is
disabled
by default.
