Is this normal or abnormal?

How much percentage of CPU usage will really affect the switch performance?

Leo Laohoo · ‎07-15-2016

1. What is the exact IOS version?

2. How many switches in the stack?

3. What is the uptime of the switches & the stack?

John Eze · ‎07-15-2016

Version - Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9NPE-M), Version 15.0(2)SE4, RELEASE SOFTWARE (fc1)

Stack uptime – 8 weeks, 4 days, 23 hours,

Switch 2 uptime - 8 weeks, 4 days, 22 hours, 56 minutes

Try using 12.2(55)SE10.

Hi John,

As per the data shared,

CPU utilization for five seconds: 50%/32%; one minute: 60%; five minutes: 76%

The problem is interrupt traffic, which is 32% here. Troubleshooting this can be little tricky as interrupts are not CPU processes but any traffic that is sent to CPU to for being processed, these could be multicast packets, ICMP redirects etc. It is acceptable to have about 10% interrupt level but anything above that should be investigated.

On 3750 platform there are some specific queues where these packets are sent. Do the following-

1. When the CPU is running high do 'clear controllers cpu-interface' and check for queue getting maximum hit using 'show controllers cpu-interface'. You need run this command repeatedly 2-3 times.

You can use the steps mentioned in the following document to troubleshoot, it contains commands and their analysis. Check for section 'Identifying Network Packets Received by the CPU'
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/troubleshooting/cpu_util.html

Debugs on this platform are CPU intrusive so I would suggest running them on console.

Apart from this you can also check for excessive broadcasts, clear counters on all interfaces and run 'sh interface | i line|rate|broadcast' after 1-2 second and check for any interface having excessive broadcast counters.

Regards,

Ashish
