8.11.3 Stacking Configuration

A supported Switch can change between stacking and standalone mode by selecting the Active
check box in the Basic Setting > Stacking > Configuration screen.
Note: When you change modes, all configurations except user accounts, but including
running configuration, config01, config02 and custom default configuration will be
erased and the Switch will reboot with a new config01. Therefore, you should back up
previous configurations if you want to reload them later.
Note: When the Switch is in stacking mode, it uses the default static IP address 192.168.1.1.
Stacking will automatically choose a master Switch in a stack but you can overwrite that by actively
forcing a Switch to become a master Switch. In the Stacking Configuration screen, click Force Master
Mode to choose the master Switch. This master Switch will have the highest priority over all other stacked
Switches even when they have same priority value.
If two or more Switches have Force Master Mode enabled, they have the same System Priority. Then the
Switch with the longest up-time is selected. Uptime is measured in increments of 10 minutes. The Switch
with the higher number of increments is selected. If they have the same uptime, then the Switch with the
lowest MAC address will be the master.

DESCRIPTION
This field displays whether the Force Master Mode is enabled or disabled on this Switch. The
Active Force Master Mode forces this Switch to become a master Switch. This Switch will have
the highest priority over all other Switch in the stack. If two Switches are set as masters, they will
have the same priority level, but the Switch that has the longest active run-time will be selected
as the master Switch automatically.
This field displays the priority level of the Switch. A higher number represents higher priority.
This field displays the slot ID of the Switch after a reboot. You can save the slot ID of the Switch
after a reboot by clicking Freeze in the Stacking Configuration screen.
This field displays whether the stacked Switch is active or inactive in a stack system.
Init means the slot ID is being initialized by the master Switch.
active* means the Switch is in the stack, but some items failed to initiate. See the system logs for
details. If the Switch is not a master, disconnect and reconnect the stacking port and wait.
Restart the Switch if it still displays active*. If the Switch is a master, restart it or choose another
master.
This field displays whether the Switch has capacity to become a master Switch. Auto means the
stack system master election process will determine if the Switch can be assigned as a master
Switch.
This field displays the stacking Switch MAC address.
This field displays the status of the port stacking channel 1 of the Switch. It will display up for
active or down for inactive.
This field displays the status of the port stacking channel 2 of the Switch. It will display up for
active or down for inactive.
This field displays the time that the active Switch in a stack has been running.
This field displays the ZyNOS firmware that is currently running on the Switch.
