Cisco WAN :: 7600 High CPU Usage BGP Router Process

Mar 22, 2011

I have an issue with 7600 router where CPU goes up to 60-70% and memory is also high. Both due to BGP Router process. URL We are seeing this issue since ISP has upgraded their router 20 days ago. Router also seen following error.I have not reset the BGP session with ISP yet. Is there any way I can supress BGP updates coming from ISP and see if CPU and memory USAGE reduces. IOS version 12.2(33)SRD and RSP720 with PFC 3cXL

Cisco WAN :: 7600 - High CPU Usage BGP Router Process

Sep 12, 2012

I have an issue with 7600 router where CPU goes up to 60-70% and memory is also high. Both due to BGP Router process. [URL] According to our baseline it should not be more than 40% at any given time. We see high CPU uptp 70% consistently.

CPU utilization for five seconds: 99%/0%; one minute: 57%; five minutes: 55%
PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

Router has 1 eBGP session with ISP from where it downloads whole IPv4 internet routing table and two IBGP session with other two rotuer. When I look at BGP summary table I see many updates received from ISP and sent out to IBGP neighbors. Also did debug BGP updates to confirm it.
 
We are seeing this issue since ISP has upgraded their router 20 days ago. Router also seen following error.

Cisco Switching/Routing :: Very High CPU Utilization Core Switch 4503?

Feb 14, 2012

We  had a core switch(30 vlans) in our environment and it's noticed that  CPU utilization of the core switch is showing high during recent days. I  have checked logs and processes, but couldn't find the root cause. The  issue found only in the office hourly only(after that the cpu  utilization is idle and normal). I have already referred the following  link to troubleshoot the issue " [URL]
 
see the following outputs from the core switch
 
CPU utilization for five seconds: 99%/0%; one minute: 99%; five minutes: 99%
PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

[code]....
 
Note: Each Invalid source mac entry in each day from same port (above is the output after clearing logs before 3 days)
  
My queries regarding the issues are following
 
1) How can we find root cause regarding the high cpu utilization?

2) Is a single invalid mac address makes the cpu highly utilized for suppressing it?

Cisco Switching/Routing :: WS-C3750X-24S / Continuous High Processor Utilization Involving Hl3mm Process

Apr 3, 2012

We are running a stack of 2 WS-C3750X-24S-E's with IOS version 12.2(58)SE2 and we are seeing continuous high processor utilization involving the hl3mm process.  The stack is configured for PIM Sparse mode, with 2 upstream Nexus 5596'es acting as both RP candidates and as BSRs.  The hl3mm process generally runs at about 19% but can spike up into the 60% range.Symptoms on the 3750X are spiking latency and sluggish CLI perfformance.  I thought at first that we might be running into SDM limits, but the "show platform tcam utilization" show that we are far under the limits of the default SDM template.  Performing the "show ip pim (vrf name) bsr-router" command freezes the system and takes 20-30 seconds to return results.  Similiarly configured WS-C3750G-12S running 12.2(55)SE3 does not exhibit these same issues.

Cisco WAN :: 886 DSL State Machine Process High CPU

Dec 27, 2010

We have a Cisco 886 configured with two WAN's (ATM0 connected to a DSL line and Fa3 connected to a CMTS modem).We're running  DMVPN over the Cable network and GetVPN over the DSL line. When the DSL line is down we see a lot of CPU peaks up to 90%.The CPU peaks are caused by the process "DSL state machine". As soon as the DSL line has sync and the ATM0 interface goes UP the CPU peaks disappear. What we'd like to know is if this constant extra CPU load will have an impact on other resources like normal routing & switching or more specific IPSEC handling. Is it for example possible that establishing an IPSEC tunnel will fail because of the CPU peaks?

Cisco WAN :: 2801 High CPU - NAT Process Or CEF Switching?

May 17, 2011

I have in my router 2801, one link with 20 MB WAN Connection, and it is presenting high cpu utilization with 97% Interrupt Errors when start one download.
 
I exchanged it to another router the 2811 and it presented the same results. I read the cisco document about Router Performance.
 
And it speaks about the 2801 supports 46 Mbps using CEF/Fast Switching and 1.5Mbps using only Process Switching, and 2811 supports 61.44 CEF and 1.5Mbps Process Switching.
  
I need to know if the NAT Process is process switching or CEF Switching. Because if it was process switching the router is working in the max capacity and i will need to exchange the hardware to a better hardware.

Cisco Switching/Routing :: 7600 High CPU Switch Processor And DFCs

Nov 16, 2011

I am a little stuck trying to troubleshoot unusually high cpu on 7600 Platform.This has been going on for many hours and not been causing a problem, but this doesn't seem replicated in our network and I am concerned about the cause.I have attached some output below, and disabled netflow on interfaces to free some switching CPU. How to track the cause of this? We only have routing protocols and 5 static routes to Null 0, so I cant see how this can be a route loop, but willing to stand corrected. Routes are learned from BGP with OSPF/MPLS internally on the network. This switch also connects to access switches on RIP and EIGRP.
 
No change has been made to this device when this problem started to occur so I am suspecting something about the traffic has changed or there is a rougue user? [code]

Cisco WAN :: 2811 High Cpu Utilization

Apr 29, 2013

I have a 2811 that is really hitting the CPU hard.  Nothing shows on CPU processes.  It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN.  The HQ has 2-3 IPsec tunnels to other remote sites.  The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%.  The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps.  I read somewhere that its possible that fragmentation could be causing this.  My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites?  Siince they use the same outside interface to my HQ, is that correct?
