3750X Stack-power issue.

datacenter
Level 1
Level 1

Hi, I'm experiencing some strange scenario on 2 3750x switches in stack mode.

After updating the IOS from 12.2(53r)SE1 to 15.0(2)SE, I'm getting some annoying logs like this:

%PLATFORM_STACKPOWER-4-UNDER_BUDGET: Switch 1 does not have sufficient power budget

Then checking the stack-power config I noticed that the Power budget from switch 1 is different from switch 2:

Power Stack           Stack   Stack    Total   Rsvd    Alloc   Unused  Num  Num

Name                  Mode    Topolgy  Pwr(W)  Pwr(W)  Pwr(W)  Pwr(W)  SW   PS

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

Powerstack-2          SP-PSS  Ring     700     271     446     -17     2    2

Power stack name: Powerstack-2
    Stack mode: Power sharing strict
    Stack topology: Ring
    Switch 1:
        Power budget: 206
        Power allocated: 223
        Low port priority value: 22
        High port priority value: 13
        Switch priority value: 4
        Port 1 status: Connected
        Port 2 status: Connected
        Neighbor on port 1: Switch 2 - c471.fe35.d600
        Neighbor on port 2: Switch 2 - c471.fe35.d600

    Switch 2:
        Power budget: 223
        Power allocated: 223
        Low port priority value: 21
        High port priority value: 12
        Switch priority value: 3
        Port 1 status: Connected
        Port 2 status: Connected
        Neighbor on port 1: Switch 1 - c471.fe56.5b00
        Neighbor on port 2: Switch 1 - c471.fe56.5b00

I searched a lot throught the internet but didn't found anything, only that the first IOS version power budget was 206 and any IOS after this uses 223.

Do you guys have any idea what i can do?

I already changed the Stack mode to redundant, strict and non-strict, but the problem remais.

Also, this model of switch 3750X consumes a lot of CPU, the HULC Led Proccess keeps on 30% almost all the time.

If you guys could help me I'll really appreciate.

Thanks in advance,

Cristiano.
