Re: HP 2650 & CPU Util

As for the port toggling - this looks like it could be LACP checking for trunk partners (or whatever it is called) when a machine brings up the port.

I have seen this in my logs as well... it's not a problem in essence... just fills the logs :)

Re: HP 2650 & CPU Util

Newest firmware is H.08.53.

I think this is happening on all ports - I have definitely seen it on most ports.
Nics connected are RTL 8139 and Intel integrated and others.

At first I thought that it was due to LACP or STP (RSTP) so I *disabled* both, but it didn't make any difference.

We're seeing random problems with saving files to UNC drives and mapped drives disappearing which might be due to the network connection fluctuating?

Re: HP 2650 & CPU Util

Hi S├Г┬╕ren,

In general the CPU Util of the switch should not be affected by normal traffic. Your level of high util, could be caused by broadcasts on the network. Other things also consume CPU time, internal logging, statistics update, response to SNMP packets (if that's how you measure it), and maintainance of routing tables etc.

In general my experience is that ~ 15% is normal...

Held og lykke ;)
