stack-power stack name appears to have changed

Charlie Jones

I have a stack of 7 3750x switches connected via Stackwise (one logical switch).  Within this switch, I have created to powerstacks (4 switches in one, 3 in the second stack).  Here is my configuration:

stack-power switch 1
 stack Powerstack1
 standalone
stack-power switch 2
 stack Powerstack1
 standalone
stack-power switch 3
 stack Powerstack1
 standalone
stack-power switch 4
 stack Powerstack1
 standalone
stack-power switch 5
 stack Powerstack2
 standalone
stack-power switch 6
 stack Powerstack2
 standalone
stack-power switch 7
 stack Powerstack2
 standalone

 

When I issue the command "Show stack-power", it looks like the stack name has changed.  Before I noticed the stack name change, I noticed that all of the stack power ports were not enabled, so I went through and enabled all of them.  In fact, when I first noticed those ports were not enabled, the output for "show stack-power" had many entries for different Powerstack (see second chart).  Any suggestions on how to fix this?  I haven't rebooted the stack yet which I have a feeling will resolve it.

Is the power stacking actually working?   Have you tested it?

The output of show stack-power should look like this:

Switch# show stack-power

Power stack name: Powerstack1 

    Stack mode: Power sharing

    Switch 1:

        Power budget: 206

        Low port priority value: 17

        High port priority value: 16

        Switch priority value: 2

        Port A status: Not shut

        Port B status: Not shut

        Neighbor on port A: 0022.bdcf.ab00

        Neighbor on port B: 0022.bdd0.4380


 

    Switch 2:

        Power budget: 206

        Low port priority value: 12

        High port priority value: 11

        Switch priority value: 1

        Port A status: Not shut

        Port B status: Not shut

        Neighbor on port A: 0022.bdd0.6d00

        Neighbor on port B: 0022.bdcf.af80
