%PLATFORM_STACKPOWER-4-PRIO_CONFLICT

forman102 · ‎08-11-2013

Hello everyone,

I ran into this issue, where my stack logs the error every minute or so:

%PLATFORM_STACKPOWER-4-PRIO_CONFLICT: Switch 1's power stack has conflicting power priorities

This is stack of 5x 3750Xs running c3750e-universalk9-mz.122-58.SE2.bin.

I attempted to fix the issue by manually assigning the priorities to make them uniqe, but that wouldn't help:

sh stack-power

Is there anything else I can do to troubleshoot this? I'd really appreciate your help.

Ok, hope this will save someone time...here's how I fixed that:

1. Switch(config)#Stack-power switch 1 - in my case switch 1 reported error

standalone - wait 2/3 minutes

no standalone

2. Checked the logs and now the same error was generated by switch 3...

Ran standalon/no standalone cmd on switch 3. After 1-st time no change, after 2nd time I found that switch 3 has conflicting High priority value with switch 4:

Power stack name: Powerstack-3

Stack mode: Power sharing

Stack topology: Ring

Switch 3:

Power budget: 703

Low port priority value: 21

High port priority value: 12

Switch priority value: 3

Port 1 status: Connected

Port 2 status: Not connected

Neighbor on port 1: 7cad.74c5.cd00

Neighbor on port 2: 0000.0000.0000

Switch 4:

Power budget: 673

Low port priority value: 23

High port priority value: 12

Switch priority value: 4

Port 1 status: Shut

Port 2 status: Connected

Neighbor on port 1: 0000.0000.0000

Neighbor on port 2: 7cad.74c5.5d00

3. Changed High priority value on switch 4, which solved the issue.

Thx,

forman

Please change priority on either switch to avoid these error messages. You
can change the switch priority by running the commands mentioned below:

 

configure terminal

stack-power switch switch-number 

stack [power-stack-name] 

power-priority switch value 

end

 

You configure the priority values of each switch in the power stack and of
all high and low priority ports on that switch by using the power priority
commands in power-stack configuration mode. These commands set the order in
which switches and ports are shut down when power is lost and load shedding
must occur. Priority values are from 1 to 27; switches and ports with
highest values are shut down first.

 

Now validate by running the command "show stack-power" if all switches have
different priorities and see if error message is gone.

please go through the document mentioned below and build the power-stack by connecting the cables as described here:      http://www.cisco.com/en/US/docs/switches/lan/catalyst3750x_3560x/hardware/in stallation/guide/HIGINSTL.html#wp1349233      Please check the setup described in figure 2-12 with 9 switches connected through stack wise cables and three power-stack configured.

HTH
