I have a lot of cisco 7206 vxr deviceses. I have a high cpu problem.I have a 7206 vxr g2. I used to use ebgp for three upstream carrier. I used to bgp full route table method. I have about 800 Mbps active traffics and behing the router about 1600 active customers.
How can I trouble shoot this high cpu problem?
#sh int gigabitEthernet 0/1
GigabitEthernet0/1 is up, line protocol is up
Hardware is MV64460 Internal MAC, address is 000c.cf1d.d01b (bia 000c.cf1d.d01b)

We have a 7206 router which acts as a MPLS Hub router for around 100+ remote locations. Bandwidh at mpls hub(terminated on this router) is 50 Mbps.
We have noticed that Memory utilization in this router gradually increases and when it reaches 100% this router hangs. It happence in frequesncy of 10 days and we have to restart the router when memory is 100%.
CPU utilization is normal i.e below 20%, WAN bandwidth will never cross 30mbps.
We are running OSPF on this router

I have a MPLS cloud in our data center. I want one network coming into our core router to have a different default route than the other networks coming in. I'm getting hits on the acl but the route isn't applied and goes to the default route that is configured in the router. I have other PBR for setting local-preferences and as-paths and they are working fine.
The router is a 7206 Version 12.4(11)T3

ip route 0.0.0.0 0.0.0.0 1.2.3.4

Has come across issues with multiple GRE tunnels between two devices when using the same source and destination addresses. I've tried using tunnel keys but this makes no difference. The only way I can get this to work is between different source & destination addresses.

i have a 7206 router to be used as a gateway for internet router 7206 inerfaces are connected directly to cisco switch 2960g note that 7600 work only at 1 gega , and cant be used for 10 or 10 . im looking forward to use router 7600 instaed of 7206 i copied the config of 7206 and pased in 7600 but some commands which are under interfaces command was not accepted here is the config which as not accepted in 7600 router
%%%%%%%%%%%%%%%%%%%%%%%%
duplex auto
speed auto
media-type rj45
negotiation auto
%%%%%%%%%%%%%%%%%%%%%%%%
note that the 4 lines above was not accpted in 7600. does these commands will affect the new config ?i just want to ask before im trying to apply this config to production network?

I am seeing a strange situation on my 6500 switch?By having snmp walk on '1.3.6.1.4.1.9.9.109.1.1.1.1.3' (== cpmCPUTotal5sec), I came to know that there are two processor and the cpu util for switching processor is gone to 88 % and some time creeps to 99 %.
snmpwalk -v2c -c "removes" sw6500 '1.3.6.1.4.1.9.9.109.1.1.1.1.3'
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.1 = Gauge32: 12 (--- this is for CPU of Router Processor )
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.3 = Gauge32: 99 (--- this is for CPU of Switching Processor )
but when I do sh process cpu on the console, all looks normal as it shows cpu utilization of RP. why the value is so high on the switching processor ?

In my bedroom I have my modem, wireless router (Netgear WGR614 v9), and my desktop computer which has a large HDD with all my movies, TV shows, and music. In my living room, I have my Xbox and new device I just recently installed, PBO (Patriot Box Office Core Media Player). The media player has ports for USB and ethernet hard drive connections.Basically what I'm looking for is a way to convert the wireless signal in my living room into a physical connection (ethernet cable) which I can plug into my PBO and watch high def (720p+ resolution) videos from my desktop.
I know that a USB wifi adapter would be simpler, but there's one thing I'm trying to determine before I buy: bottlenecking. I crunched the numbers (not quite sure how accurately mind you haha), and here's what I saw - a recent bandwidth test (using my desktop) reported my upload speed around 3000kpbs (375KB/s), whereas the sustained speed of USB 2.0 is reportedly anywhere from 5MB/s to 15MB/s (way higher).

I have 2 6509-E chassis with SUP-720-VSS and classic line cards :-(. on October 2011 the switch reached 100% CPU on both devices and the entire network went down. Customer restarted the core so we lost all the log files and couldnt find out any root cause on the same. TAC engineer suggested to have some script configured on the system in case of CPU shooting up above 70%, it will create a file in flash and keep appending the logs to the same. Last week i got call from customer saying that the CPU again went high for around a minute on both the cores. Last time i added CoPP also on the switch in order to prevent the CPU reaching 100%. Still it went high and from the captured logs i saw that the process created the high CPU was Port Manager Per and SSH process. Attached the file created by the netdr capture command.

The fans 1 & 2 in Module 1 on the Nexus5K are still experiencing the very high RPM and speed issue.
I have replaced the fan from another operational Nexus5K, and the fans are fine in the other Nexus. The replacement fans also have the same issues, so it is not a fan hardware issue.
There are no threshold alarms. the only log entry that is related to this is as follows:
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 1. 7950 to 12500 rpm expected. I have provided the output for both the fan detail and the temperature.

Currently, my Cisco 3750x (2 switches stacking) is having very hight CPU. Below are some of the output :

I am not sure what is using CPU to go up like this. I had tried some troubleshooting guide on Cisco web site like "Troubleshooting high CPU Utilization"

I have a one question. I am using Cat3750x-48 switch. Suddenly it has occurred following high CPU log message in Cat3750x-48 switch.
%SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 62%/0%, Top 3 processes(Pid/Util): 162/40%, 156/10%, 74/1%
What is meaning of PID 162 ?

my 3750-E Core Stack is connected to the Provider Router and is the DG for the internal LAN. I saw that the CPU is very high also in the night, but I found not the problem. I use an SVI to connect the provider due to HA reasons. I sniffered the network but saw no ecessive broadcaststorms. There was a PBR configured but I deleted it wihtout any success..

We are facing high CPU Utilization on Cisco 3750X-48P-L without any traffic on it. find the attached log files for 2 separate 3750's stack, we have upgraded the IOS of SW2 from "c3750e-universalk9-mz.122-55.SE3.bin" to "c3750e-universalk9-mz.122-55.SE4.bin" but still we found the same issue with CPU utilization.

I've been looking at reported problems with our Vdeio Conferencing kit attched to a stack of 3750's (which I think is down to QoS) but this got me looking at the logs. We get a lot of high CPU utilization warnings mainly for SNMP (315), Hulc running con (95), Virtual exec (289). I understand the last two are normal, and the SNMP one is probably Cisco Works polling as it happens every 4 hours.
However I've got an odd one: Apr 25 07:34:58: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 93%/0%, Top 3 processes(Pid/Util): 296/85%, 144/0%, 154/0%
What is Pid 296? It's not listed on the switch:

Seeing very high CPU on one of our 3750X stacks. Usally its around 30% but recently its 70, 80, 90 or maxed at 100% during the main day.IOS version c3750e-universalk9-mz.122-55.SE1.bin.Has a ten gig uplink connected to a nexus 7k and another ten gig connected to another 7k. Running Layer 3 and EIGRP on the 3750X.Is this normal for the CPU?

I am facing a problem on a 2811 router. The CPU is remaining around 60% and the router throughput is reaching at most 18 MB while according to the data sheet the 2811 maximum throughput is 61MB. I have checked the output interpreter in order to try and figure out the cause of the high CPU and to determine if it is affecting throughput but there are not processes consuming more than 10%. I have attached the show tech-support and the show process cpu history outputs.
