my Company use 2 Cisco c9300-24T as Stack. Now, we want to add a new Switch to this Stack.
Today I recieved the new switch and downgrade the firmware to the same running on stack. That was fine after reload sh ver shows the equal firmware like the stacked on.
Furthermore I read the guide here: LINK
My stack has two switches, both has priority 1 and switch stack number 1 and 2.
I want the new switch to add them stack number 3.
I am confused how to add the new switch.
1. should I turn off the new switch, put the stacking cable and power them on and all is fine?
2. Should I do offline configuration to provision a stack member?
a) On stack I type: switch 3 provision c9300-24T
b) New switch I type switch 1 renumber 3
c) wr mem
d) power off and connect to stack switch
Which way is the best to add a new device to an existing stack?
Solved! Go to Solution.
Your steps are almost correct.
Make sure you issue the switch 3 provision c9300-24T command on the running switch stack, cable in the new switch into the stack, and then power it on.
With the exception of the image downgrade on the new switch, there are no commands you need to run on it prior to connecting to the new stack.
thank you for your answer. When I follow the guide linked above I should do the provision on the stack and on the new switch I should add a stack member number.
You manually create the provisioned configuration through the switch stack-member-number provision type global configuration command. You must change the stack-member-number on the provisioned switch before you add it to the stack, and it must match the stack member number that you created for the new switch on the switch stack. The switch type in the provisioned configuration must match the switch type of the newly added switch. The provisioned configuration is automatically created when a switch is added to a switch stack and when no provisioned configuration exists.
I have forgotten to say that this is my very first time to add a new device to an existing stack. So I am a bit carefully.
