Adding a new node to stack failed - no neighbor

[holden]

Hi,
im trying to add a new x440p to an existing x440p stack of 2 devices.
Unfortunaly the stack doesnt see the new member in his list of show stacking.

i have already tried mayn times the steps in the concept guide and enabled switching, set slot number and license level. I have also checked that the same image from the same slot will be loaded.Stacking leds are all green.

But the new device doesnt come up in the stack.



on the new device

* Slot-1 Stack.2 # sh stacki
Stack Topology is a Daisy-Chain
Active Topology is a Daisy-Chain
Node MAC Address Slot Stack State Role Flags
------------------ ---- ----------- ------- ---
*00:04:96:97:be:09 1 Active Master CA-



On the existing stack

Slot-1 Stack.20 > sh stacking

run cmd enable stacking with node address then reboot and try

Did you try following this method ?

If that does not work, check the logs on each slot as it might tell you why it is not working.

i too have similar issue facing if we enable stacking in the new switch then it will be visible in the existing stack summary
