I have a stack of 8 extreme switches. Their roles are this
Switch 1 master (x670)
Switch 2 standby (x460g1)
Switch 3 standby (x460g1)
Switch 4 standby (x460g1)
Switch 5 standby (x460g1)
Switch 6 standby (x460g1)
Switch 7 standby (x460g1)
Switch 8 standby (x460g1)
They are in a ring configuration, slots 1 and slot 8 both have core licenses.
I wanted to set the stack to have a backup node.
So I issued the command, configure stacking node address (appropriate slot's mac) master-capability OFF for slots 2 thru 7
I issued configure stacking node address master-capability ON for slot 8
I then issued the command configure stacking redundancy minimal
Thinking that master-capability on 2 nodes (slot 1 and slot 8 in my case) would be the logical choice.
I scheduled a reboot for after hours and found the stack to be this way: the stack came up but slot 2 had license mismatch and didn't have a role. Perplexing.
I had to again issue the command conf stacking node address (slot 2) master-capability OFF and reboot that node individually to get it to come back up.
Stack is now this way: As you can see slot 8 is not a backup.
Switch 1 master
Switch 2 standby
Switch 3 standby
Switch 4 standby
Switch 5 standby
Switch 6 standby
Switch 7 standby
Switch 8 standby
1) should I try configure stacking redundancy maximal (instead of minimal that I tried)?
2) Can it be slot 1 and slot 8 for a master and backup situation? I know typically it would likely be slot 1 and 2 but that's not where our core license is. We are using slot 1 and slot 8.
