Switch Stacks

Managed Switches 
The following table provides switch stack configuration scenarios. Most of the scenarios 
assume that at least two switches are connected through their stack ports.
Table 4.  Switch stack master scenarios
 
Scenario
Action
Result
Stack master election specifically 
determined by existing stack 
masters.
Connect two powered-on switch stacks 
through the stack ports.
Only one of the stack masters 
becomes the new stack master. 
No other stack members 
become the stack master.
Stack master election specifically 
determined by the stack member 
priority value.
• 
Connect two switches through their 
stack ports.
• 
To set a stack member to a higher 
member priority value, issue the 
switch stack-member-number 
priority new-priority-number
 
global configuration command.
• 
Restart both stack members at the 
same time.
The stack member with the 
higher-priority value is elected 
stack master.
Stack master election specifically 
determined by the MAC address.
Assuming that both stack members have 
the same priority value and firmware 
image, restart both stack members at the 
same time.
The stack member with the 
higher MAC address is elected 
stack master.
Add a stack member.
• 
Power off the new switch
• 
Through their stack ports, connect the 
new switch to a powered-on switch 
stack.
• 
Power on the new switch.
The stack master is retained. 
The new switch is added to the 
switch stack.
Stack master failure.
Remove (or power off) the stack master.
One of the remaining stack 
members becomes the new 
stack master. All other 
members in the stack remain 
stack members and do not 
reboot.
Preconfigure a Switch
You can preconfigure (that is, supply a configuration to) a new switch before it joins the 
switch stack. You can specify the stack member number, the switch type, and the interfaces 
that are associated with a switch that is not currently part of the stack. 
Note:
If you are replacing a switch with the same model in the same position 
in the stack, you do not need to preconfigure it. The new switch 
assumes the same configuration as the previous switch.
Note:
NETGEAR does not 
recommend this scenario.
