How to do Stacking Role from NONE to Backup
---------------------------------------------------------------

X250e-48p and x250e-48t Stacking. I want to achieve Master and Backup Stack Topology. Please advice me how to configure it. Thanks.

Slot-1 Stack.1 # show stackingStack Topology is a Ring

(O) node may be in Other active topology

That looks right assuming all these commands were entered on only one switch. Try running the "synchronize stacking" command and reboot the stack. After the reboot give it a couple minutes to sync up and see if slot 2 has a role.

Paul,

All nodes in a stack must have matching image versions on the same matching partition. Example: If you are running 15.3.4.6-patch1-5.xos on your primary partition on slot 1, you must have the same version on the same partition on slot 2.

This is how we configure our stacks:

Master Stack:

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

enable stacking node-address



conf stacking node-address slot-number 1

conf stacking node-address master-capability on

conf stacking node-address priority 70



conf stacking node-address mac-address

conf slot 1 module

save

reboot node-address

Backup Stack: Master Capable

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

enable stacking node-address



conf stacking node-address slot-number 2

conf stacking node-address master-capability on

conf stacking node-address priority 60

conf slot 2 module

save

reboot node-address

synchronize stacking node-address

Patrick, please correct this if I am wrong in any way.

Thanks and good luck,
Stan

Hi Stan,

I use the same version, same partition and enable the master-capability yes. Thanks.

I think the 2nd slot has master-capability turned off so it cannot be backup or master.
Refer to the documentation to enable master-capability of slot 2.
http://documentation.extremenetworks.com/exos/EXOS_All/Stacking/t_configure-mastercapability.shtml

• configure stacking slot 2 master-capability on
• Then reboot slot 2.

Hi OscarK,

I have enabled the master-capability on slot 2. Thanks.

Slot number : 2
Stack state : Active
Master capable? : Yes
Stacking protocol : Standard
License level restriction : Edge
