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

The above article should help you with the protocol configuration change.

Hi Denu,

I am suspecting the issue might be related to the stacking protocols as you are not able to see the new switch when connected to the existing stack. Please check the following output.

show stacking detail

in both the existing stack and the new switch.
Check the stacking protocol under this output and make sure that the stacking protocol in the new switch is same as the existing stack.

command to configure the stacking protocol is,

configure stacking protocol .

Hope this helps!

thats what i have already done many times. unconf stack and unconf switch and tryied it again with enable stacking. but it isnt shown in the list of the stack.

[holden]

yes, but this doesnt work, because the new member ist shown in the stacking list

[holden]

this doesnt work when the MAC of the member isnt listed in show stacking
