Cisco Switching/Routing :: 6500-E VSS High CPU Utilization Process IOS-Base
Apr 18, 2012
we are using Cisco 6509-E VSS mode [12.2(33)SXI] ipbase image and facing high cpu utilization. In show process cpu output it is showing some "ios-base" process consuming cpu. I attached show cpu output
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.
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 ?
Each time I enter show run on my router 2821, it takes ages to display and I have a cpu peak from the ssh process ( I am connected through SSH)

We suddenly noticed high CPU utilization on one of our 7600 routers. I output of show process CPU showed high utlization for the FM core process. I looked it up but did not find information on what this process does. [code]
I have a process whick take all the CPU on two differents Stack of WS-C3750G in version 12.2.53(SE2):

I have a router 3845 with c3845-advsecurityk9-mz.124-24.T6.bin software . Frequently we are facing problem in logging to the device .Inorder to resolve we need to reboot the router . Yesterday fortunately i have got the console access for some time so i came to know that TPLUS process is consuming 99.9% percentage cpu.

We are experiencing with high CPU input due to ARP input between 20:30 and 22:30 every day At this time we have a lot of backup operations. When I look the netflow report, I can't see anything anormal.
We are changing our backup server's NIC card from 1gig to 10Gig. The backup operation's traffic is high (approx 2Gbps level) but 6509 has to be handle this size of traffic.
We are using two 6509E in VSS mode and our image version is s72033-adventerprisek9_wan-mz.122-33.SXJ.bin

I'm facing high CPU utilization issue due to a ssh process on 3750 switch. What is the use of SSH proces in the switch? Can I disable it for troubleshooting?
will there be any impact if I disable it?

document which explians normal booting sequence in a 6500 Switch running IOS. What I am looking for is in which order the image is loaded in SUP, RP, SP etc
We are looking to upgrade the version of IOS on the 6500s this evening and in preparation i've dowloaded the image to sup-bootdisk. However when trying to update the boot path as follows I see the following error: [code] Why are we seeing this message when the router is not doing anything with ISSU?
The switch 6500-E is frequently crashing whenever the pm scp process reach 100% .I got it under the command "remote command switch show proce cpu".How to solve the problem. I opened the TAC and the engineer says to upgrade the image12.2(18) sxf.Is there any other work around that would avoid to reimage the switch and reloading.
We are cutting over from 6500 IOS to Nexus 7000 and have hit "Maximum ospf feature instance limit reached." as we configured up the 7 existing ospf processes - the limit is 4. These existing processes are for various vrf contexts we have. I see you can run multiple vrf contexts under one process - but how does that work in a mixed environment where the ospf neighbours are still ios 6500s? They still expect to see different ospf process id per vrf.
we have configured SSh on our primary and secondry core switch , SSH is working on primary Switch but we are unabme to access secondry Core switch through SSH .
Error are as under :

We have a Cisco 3845 router configured as a voice gateway with multi SIP trunks. But when it reachs 200 calls traffic, the CPU increase to 60-70% and caused by CCSIP_SPI_CONTROL process.

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%
From couple of weeks we have observed the cpu utilization of cisco 6509 with SUP 720 is high. During daytime from 9:00 to 21:00 it keeps increasing & reaches 98% & after 21:00 becomes normal.
I have a 2 cisco core (cisco WS-C6509-E (R7000) processor) and been working for quite sometime.they are conneted with HSRP with active standby config with a 10 g module for redundancy just today I see that the cpu utilization went to about 50% and its the same on both cores.
I have some events where the CPU utilization in a cluster switches of WS-3750 is going to 100%, the process with the major utilization of CPU is the "hulc running con".
We have seen high CPU utilization on some Cisco switches of type 2960S. Also we got info, that applications are running with poor performance or with interruption.Following IOS is loaded: C2960s-universalk9-mz.122.55.SE
We will be converting two 6500s to VSS. Each chassis has a Sup2T module, fwsm, 6908-10G blade, wism1 blades and two or three 6748-SFP blades. I was wondering how long the conversion process takes? If I remember correctly at the 2012 networkers lab it took maybe 10 minutes while using Sup720s. The instructor mentioned that with Sup2Ts it would convert a lot faster.
In Cisco 3750 facing high CPU utilization for specific period. During this period traffic response times across the switch degrades. Steps to identify interface potentially generating traffic. I have attached 'sh proc cpu history' , ' sh ip traffic', 'sh proc cpu sorted' during troubled period .
We have cisco 4510R+E switch with IOS-XE Software Version 03.01.01.SG RELEASE SOFTWARE (fc1).Our this switch is having two core & one core is always going to about 90% to 98% cpu utilization while other core is showing normal (about 5% to 10%),we check with-This switch is gateway of our LAN.
I am running a 1712 12.4(25d) with NAT, VPN and FW/IDS. I have a broadband ethernet connection at 20mb. As I run some traffic through it, the processor jumps up to near 100% and throughput comes to a screeching halt. IP CEF is turned on and makes no difference when it is turned off or on.
I am a new network engineer on a retail company and I am having a problem on the High utilization of my 3-stack switch 2960 only during Peak Hours of the Store Sales.
Note: on Peak hours, it is peaking at 90-95 % here is the utilization after Peak hours: 4444333334444433333333333333333333333333333333333333333333
