SNMP: CPU usage on ProCurve 5406zl

Hi all,

When I use SNMP to read out the CPU usage on our 5406zl's, some of our switches consistently report "1". Normally, that's a good thing, but I don't buy it.

Example output:
STATISTICS-MIB::hpSwitchCpuStat.0 = INTEGER: 1

Our other switches report varying results, normally between 3 and 15 percent. All switches are in the same spanning tree. One of the switches reports 1 most of the time with spikes to "normal" levels. The configuration of the switches are where possible identical ('snmp-server community "switch" Operator' among other things). Other SNMP-values seem to be correct.

Anyone any idea what this might be?

This behavior should be normal and OK.

On my 5412 its similar.

In older Firmwere Versions of 54xx the load was permanently around 20%

But now it is only high if there is a reason for it.

Go to cli, type "sh sys" . Your will see values beween 0 and 5 % too.
