Re: CiscoWorks2000 and snmp problems [7:54865]
Yes that URL is exactly what I sent to a customer many months ago when they had the same problem. SNMP would request the whole routing table, they are receiving the whole Internet routing table, which caused their 7200 CPU utilization to max out. There should be no reason the grab this table via SNMP so cutdown will help you if this is similiar to your scenerio.

I had the same problem before...it had to do with ATA flash disk and ciscoFlashMIB check here for the work around. http://www.cisco.com/warp/public/477/SNMP/ipsnmphighcpu.shtml - Original Message - From: bi.s To: Sent: Friday, October 04, 2002 2:25 PM Subject: CiscoWorks2000 and snmp problems [7:54865] hi, i am interested if there is someone using cw2k and has c7200 vxr with npe-400. do you have problems with snmp on the routers? on other routers? it looks like there is a problem with snmp causing high cpu on routers and bringing the network down. has someone this problems? how did you solve them? ios upgrading doesnt help and the cisco case was closed without a fix. is snmp-server view cutdown an option (http://www.cisco.com/warp/public/477/SNMP/ipsnmphighcpu.shtml). any experiences with that? thanks -bis Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=54869t=54865 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: CiscoWorks2000 and snmp problems [7:54865]
I had a similar problem but with our cat 5500's. The CPU would spike to 95% utilization every couple of minutes. Before I get into what we did, try going under Resource Manager Essentials = Administration = Change Polling options = choose the 7000 series routers and try to manipulate some of the polling options. If this doesn't work. See if this is caused by Device Fault Manager. Go to Server Configuration = Administration = Stop Process = shutdown DFM Server and DFM Broker and see if that resolved anything. If all else fails, reopen the case with Cisco. Hopefully you will get a more experienced tech this time.

Re: CiscoWorks2000 and snmp problems [7:54865]
I had this problem several weeks ago. I removed MIB ciscoEntityAssetMIB from CiscoWorks. Check out CSCdu55091 on CCO. Or you can configure the following on your routers: snmp-server view cutdown ciscoEntityAssetMIB excluded snmp-server community public view cutdown RO snmp-server community private view cutdown RW Hope this helps, Stephanie bi.s wrote:hi, i am interested if there is someone using cw2k and has c7200 vxr with npe-400. do you have problems with snmp on the routers? on other routers? it looks like there is a problem with snmp causing high cpu on routers and bringing the network down. has someone this problems? how did you solve them? ios upgrading doesnt help and the cisco case was closed without a fix. is snmp-server view cutdown an option (http://www.cisco.com/warp/public/477/SNMP/ipsnmphighcpu.shtml). any experiences with that? thanks -bis Do you Yahoo!?

Re: CiscoWorks2000 and snmp problems [7:54865]
Yes it took care of the issue for this customer, my guess would be that SNMP is grabbing some large table it doesn't need.
