X450A switch stacking in live network


Hi Guys,

I was working on expansion of X450A extreme switches recently in a network where one of the witch was running live and catering to the traffic. With help from some posts and research, here is the procedure with which you can acheive this stacking activity:

1). Check that both master and expansion switch should be running on the same "Image"
Image Selected: primary You can check this with the help of "show switch" command.


2). Unconfigure the expansion switch so that its fresh as new.

3). for "enable stacking", mark the answer as "no", since we'll be using the manual method.

4). Connect the stacking cable form master switch to expansion switch.

5). Run "show stacking" on master switch and you will see the MAC of expansion switch also now.

Node MAC Address Slot Stack State Role Flags

------------------ ---- ----------- ------- ---

00:04:96:6d:3f:6a - Disabled Master ---

*00:04:96:83:4e:b1 1 Active Master CA-

5). Run the following commands on the master switch:

configure stacking node-address slot-number 2

configure stacking node-address license-level advanced-edge


configure stacking node-address master-capability off


synchronize stacking node-address


reboot node-address


6). Now once your expansion switch comes up after the reboot, It will be stacked with the master switch. And this procedure does not hamper any traffic going through the master switch.

Node MAC Address Slot Stack State Role Flags

------------------ ---- ----------- ------- ---
00:04:96:6d:3f:7c 2 Active Standby CA-
*00:04:96:7e:04:ed 1 Active Master CA-



you can verify your stack using "show switch" and "show slot" on the master switch.

PS: I hope this is helpful for you.
