Enable SummitStack-V on single switch?

[Eric_Burke]

In the past, our best practice was to enable stacking on everything (including single switches), allowing for future additions to the switch without having to suffer an outage and reconfiguration. It seems that when using 10Gb stacking on a 460-G2, unless you boot with a connected "secondary" switch, the enable stacking command has no impact and the switch refuses to enter stacking mode by itself. Can anyone confirm this behavior? Any suggestions to accommodate the expansion without reboot scenario?

Thanks,
Eric

What EXOS version are you running?

I did a quick test in my lab and don't see this, i.e. I am able to enable stacking on a single node:

* Slot-1 Stack.1 # sh slot
Slots Type Configured State Ports
--------------------------------------------------------------------
Slot-1 X460G2-48x-10G4 Operational 54
Slot-2 Empty 0
Slot-3 Empty 0
Slot-4 Empty 0
Slot-5 Empty 0
Slot-6 Empty 0
Slot-7 Empty 0
Slot-8 Empty 0

* Slot-1 Stack.2 # sh stacking-support

Stack Available Ports

----- ----------------- ---------- ----------
1 Yes 51 * Alternate Alternate
2 Yes 52 * Alternate Alternate
stacking-support: Enabled Enabled

* Slot-1 Stack.3 # sh stacking
Stack Topology is a Daisy-Chain

This could be code related.

We have several X460-G2s deployed as single switch stacks using the alternate front ports.
