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.

Hi Paul,

The role coming up as none could me a couple different things. Moving forward I would recommend looking at the logs to see if it tells you why or use the "show slot" output. It could be a license or image mismatch. If you would like to post these outputs for evaluation I would be happy to take a look.

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

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.

RE: How to do Stacking Role from NONE to Backup

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.

Hi Patrick,

I run the sh slot 2 and found out that it is because of License Mismatch.
Slot 1 is Edge and Slot 2 is Trial.
But any way how can i test this work.

Does it make sense? if i use this debug command in Slot 1 and make it as same license.
My current slot 1 license will be removed?

I used debug epm... command to Slot 2.
debug epm enable trial-license # hidden command to enable license for 30 days trial

You will need to run the "debug epm clear trial-license" command and then reboot in order for it be removed. This should resolve your issue assuming slot 2 has the same default license. Trial-license should not be run on a stack or on any switch that is going to be put into production.

Thanks Patrick,

Now my issue have been resolved by your informative advice.
I do thank you for your prompt response.

Hi Paul,

I have created an article on how to troubleshoot a failed or role-less node in a stack:

https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-troubleshoot-a-failed-node-or-a-node-without-a-role-in-a-stack

Please let me know if you feel like this will help in the future. Any feedback is welcome as well. I can update this article at anytime.

Hi all,

I will keep on update here. don't want to create another post. Since it's related to this stacking.

My question is How Can I Add Different Module to the current configured Module. Please see below for more detail.

I have uploaded the configuration to the Stack.
Current Configuration for Slot 1 is X250e-48t
and Now Replacement unit module is X250e-48p

if i use unconfigure slot 1.
Configuration will wipe out slot 1 config. i don't want to do it.

Please advice. How can i achieve without effecting the current config for port and vlan for slot 1 except changing from X250e-48t to X250e-48p. Thanks.

Slot-2 SW # unconfigure slot 1
This slot will be rebooted as part of this operation.

This will remove all port and vlan information for ports in this slot(1).
Any ports on this slot that are members of load share groups will be removed
from the load share group.
Continue ? (y/N)

configure slot 1 module X250e-48t
configure sys-recovery-level slot 1 reset
configure slot 2 module X250e-48t
configure sys-recovery-level slot 2 reset

Slot-2 SW # sh slotSlots Type Configured State Ports

Slot-1 X250e-48p X250e-48t Mismatch 50

From my knowlegde unconfigure slot 1 and reconfigure the ports and vlans on it is the only option to replace a slot with a different slot.

RE: How to do Stacking Role from NONE to Backup

Paul11 — Mon, 20 Jul 2015 11:43:00 GMT

Hi OscarK,

It means i have to reconfigure the current configuration in order to replace different module in Stacking. 

RE: How to do Stacking Role from NONE to Backup

OscarK — Mon, 20 Jul 2015 11:46:00 GMT

Yes, but only for slot 1, all vlans still exist, as is other configuration, only port assignment and port specific configuration actions need to be done.
