election specifically determined by existing
|
Connect two powered-on switch stacks through the StackWise ports.
|
Only one of the two becomes the new .
|
election specifically determined by the stack member priority value
|
-
Connect two switches through their StackWise ports.
-
Use the switch
stack-member-number priority new-priority-number
command to set one stack member with a higher member priority value.
-
Restart both stack members at the same time.
|
The stack member with the higher priority value is elected .
|
election specifically determined by the configuration file
|
Assuming that both stack members have the same priority value:
-
Make sure that one stack member has a default configuration and that the other stack member has a saved (nondefault) configuration
file.
-
Restart both stack members at the same time.
|
The stack member with the saved configuration file is elected .
|
election specifically determined by the MAC address
|
Assuming that both stack members have the same priority value, configuration file, and license level, restart both stack members
at the same time.
|
The stack member with the lower MAC address is elected .
|
Stack member number conflict
|
Assuming that one stack member has a higher priority value than the other stack member:
-
Ensure that both stack members have the same stack member number. If necessary, use the switch
current-stack-member-number
renumber
new-stack-member-number
command.
-
Restart both stack members at the same time.
|
The stack member with the higher priority value retains its stack member number. The other stack member has a new stack member
number.
|
Add a stack member
|
-
Power off the new switch.
-
Through their StackWise ports, connect the new switch to a powered-on switch stack.
-
Power on the new switch.
|
The is retained. The new switch is added to the switch stack.
|
failure
|
Remove (or power off) the .
|
The standby switch becomes the new active switch. All other stack members in the stack remain as stack members and do not
reboot.
|
|
-
Through their StackWise ports, connect
devices.
-
Power on all devices.
|
Two devices become . One has stack members. The other remains as a standalone device.
Use the Mode button and port LEDs on the device to identify which device are and which device belong to each .
