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 and config02 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.
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 Active 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 Active Force Master Mode enabled, then the Switch will use System Priority
to determine which is master. If 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.
This is the master election priority in a stack system:
Active Force Master Mode
1
Highest Stacking Priority
2
Longest System Up Time
3
Lowest MAC Address
4
Note: Master election occurs when a stacking port link status changes (up / down). The link
status changes when (for example):
- a stacking port cable is disconnected
- a Switch in the stack reboots (as happens after you change stacking mode to
standalone)
- you add a Switch to the stack or
- a Switch in the stack shuts down.
