You can manage each Switch in the stack from a master Switch using its web configurator or console.
Each Switch supports up to two stacking channels. Use the master Switch to assign a 'slot ID' for each
'linecard' non-master Switch. 'Slot' refers to a Switch in the 'virtual chassis' stack.
You can build a Switch stack using a ring or chain topology. In a ring topology, the last Switch is
connected to the first.
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 using the Stacking force-master command. 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 Stacking force-master enabled, then the Switch will use Stacking
priority to determine which is master. If they have the same Stacking 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:
1
Stacking force-master
Highest Stacking priority
2
Longest System Up Time
3
Lowest MAC Address
4
Note: Master election occurs when stacking / standalone mode changes or when a stacking
port is temporarily disconnected in stacking mode.
