NETGEAR 7000 Series Managed Switch Administration Guide Version 7.3
• You can connect to the stack master through the console port of the stack master only.
• You can connect to the stack master by using a Telnet connection to the IP address of the stack.

Switch Stack Configuration Scenarios

Table 20-2 provides switch stack configuration scenarios. Most of the scenarios assume at least two switches
are connected through their stacking ports.
Table 20-2. Switch stack configuration scenarios
Scenario
Stack master election specifically determined by existing stack
masters
Note: This is not recommended.
• Connect two powered-on switch stacks through the stacking
ports.
Stack master election specifically determined by the stack member
priority value
• Connect two switches through their stacking ports.
• Use the switch stack-member-number priority new-priority-
number global configuration command to set one stack member
to a higher member priority value.
• Restart both stack members at the same time.
Stack master election specifically determined by the MAC address
• Assuming that both stack members have the same priority value
and software image, restart both stack members at the same
time.
Add a stack member
• Power off the new switch
• Through their stacking ports, connect the new switch to a
powered-on switch stack.
• Power on the new switch.
Stack master failure
• Remove (or power off) the stack master.

Result
Only one of the two stack masters
becomes the new stack master. None
of the other stack members become
the stack master.
The stack member with the higher
priority value is elected stack master.
The stack member with the higher
MAC address is elected stack master.
The stack master is retained. The new
switch is added to the switch stack.
Based on "Stack Master Election and
Re-Election", one of the remaining
stack members becomes the new stack
master. All other members in the stack
remain stack members and do not
reboot.
