I have a existing switch stack with 4 switches in the stack (all of them are 3850).
Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 56 WS-C3850-48U 03.03.05.SE cat3k_caa-universalk9 BUNDLE 2 56 WS-C3850-48U 03.03.05.SE cat3k_caa-universalk9 BUNDLE 3 56 WS-C3850-48U 03.03.05.SE cat3k_caa-universalk9 BUNDLE 4 56 WS-C3850-48U 03.03.05.SE cat3k_caa-universalk9 BUNDLE
Now, I have to add another switch (3850) to that stack.I found out that the the member number of the new switch is 1 (which is default) and the priority is set as 15. Also they new 3850 is in INSTALL mode and does not have the .bin file which is on the stack. The IOS version is the same on the stack as well as the new switch.
Here is how I am planing to add this switch:
- Turn off the power of the new switch
- connect the stacking cable (according to Cisco documentation)
- Turn on the power of the new switch
By doing this the switch should automatically get the stack number and priority value of 1.
Now my question is: since the new switch has priority value of 15 before adding it to the stack, after adding the switch to the stack following above procedure, can this switch reboot the entire stack and reelect the master switch? If yes, how can I avoid this. Also will the INSTALL mode and BUNDLE mode cause any problems?
