Cisco 6509 modular IOS getting high cpu in interrupt but the switch process switching is still less. Any sugeestion what could be the problem?
Process sbin/ios-base, type IOS, PID = 16407CPU utilization for five seconds: 12%/81%;
Sometimes cpu goes upto 100%
Version - s72033-ipservicesk9_wan-vz.122-33.SXH5
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 having two Cisco 6509 both working are my main Core Switches with which I have all my Layer 2 VLANs configured and then distributed thru the trunks links to all the Access Switches. I have L3- Vlans also configured on them with which one switch in primary and the other is secondary. All of sudden last night I got this message on my core switch 2 this for VLAN 1 which is my users LAN, how can I check as to what would have caused the core switch 2 HSRP to be active and then in standby
*Nov 5 23:33:29.296: %HSRP-5-STATECHANGE: Vlan1 Grp 5 state Standby -> Active
*Nov 5 23:33:29.796: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Standby -> Active

Also last night i got call from office saying that we are getting huge delay in pinging the default gateway of the user LAN which is the same vlan as the above and it was just for few minutes and then it was back to normal and now when I came to office and check there were no logs in both the core switches. When I checked the cpu utlization it was showing me high on both the switches how can I check as to what would have caused the CPU utilisation to go high all of suddedn?

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.
View 4 Replies View RelatedI'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%

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".

I am looking at the utilization on a Catalyst 3560-E. I am running a test with eight 1 GIGE links RXing at 95 % utilization. All of the traffic is going to a TenGigE port. The device on the TenGigE port is echoing back all of the traffic received, so the 1 GIG links are TXing at 95% as well.When I do a "show controllers utilization", the port utilization numbers are correct, but the fabric utilization is higher than I would expect. The fabric should be 128 gigbits / second in this switch, and there is 7.6 gigabits TX/RX to the ten gig port. The fabric utilization is at 49%. I would expect 7.6 / 128 = 5.9% or possible double that. [code]

I have a Switch WS-C3750E-48PD-SF with IOS 12.2(58)SE2 which reports more than 80% in utilization of memory I don't know what is causing the high memory utilization.
View 14 Replies View RelatedI have been facing High CPU Utilization issue with few of my Cisco 4006 Switches together from last one month. Out of which 1 switch issue sorted out auto after 2 days however the problem is still exists with rest 3 switches.They are 6-7 year old and having one SUP engine and other are switch port modules.
View 5 Replies View RelatedWe have just purchased Cisco 3750X 24 S switches (QTY 2), last week we put them in prodcution in simple Layer 2 mode. No Core, just act as Access switch in order to only check the performace and availibility of switches.
But strange thing I have noticed the highest cpu utilization, cpu sits on 13 to 14% and from historical logs it hit above 60%. I am confused what is happening. Remember to terminate copper connection we have inserted Copper SFP Modules on both switches.
Both switches connected on Layer 2 mode via trunk, in LAN environment we have here 7 3Com 2824 Management switches which are terminated on Copper SFP modules at Cisco 3750X 24 S. All 3Comm Switches uplink are terminated on Cisco 3750 Switch 1, another switch is idle. Whole setup is running on VLAN1 .
Also refer no port in TCP and UDP packets in show ip traffic. any abnormal condition you predict..basically, In near days we plan to make these switches as Core layer and run intervlan routing, HSRP/VRRP and OSPF. But in this cpu usage how we can go ahead until this resolved..
We've got Cisco 2821 for our 90mb/s Internet Access. Its CPU usage is around 80%. Show process cpu does not show any cpu proccess with high utilization. But we have got plenty of policing configured for our clients using policy maps. Can this policing affect cpu usage?
View 1 Replies View RelatedI noticed on the 2960 switches we have deployed that are running the latest IOS, 12.2(58)SE2, memory utilization is really high (almost 80 percent). I have not noticed any side effects but I wanted to verify this is acceptable. My question is does the high memory utilization matter? I see this may be related to bug CSCtw83946 but no resolution is mentioned.
I did some testing various IOS revisions and below is what I have found using a WS-C2960-48TC-L with default configuration and only my laptop connected to a switchport in vlan1. You will notice memory utilization will grows with each version but jumps drastically with 58. One difference with 58 I needed to use a different command to retrieve memory utilization. The output was gathered by pasting the output of the show command into the Cisco Output Interpreter on their website.

I have a Head Quarter and a remote site running over a OC3 circuit. [code]
On the HQ, I have a Cisco VXR7204 running IOS 12.4.15T(10) Advanced IP Serviceand the remote site is a Cisco 2851 also running IOS 12.4.15T(10) Advanced Ip Service. The HQ has a Riverbed Steelhead 5050H capable of delivering 100MbpsWCCP throughput. The remote site has a Riverbed Steelhead 1050H which can deliver 10Mbps WCCP throughput. At the HQ, the LAN network is 192.168.251.0/24.The Steelhead residing on the 192.168.251.0 network.At the remote site, the LAN network is 192.168.103.0/24 and 192.168.211.0/24.The Riverbed resides on the 192.168.103.0/24 network.
When a host on network 192.168.211.0/24 download a file from network192.168.251.0/24 network via http, the CPU on the Cisco 2851 goes to 99% utilization and that it stays there for the duration of the http session. There is very little traffic goes across the WAN whichis the way it should be but the CPU on the 2851 stays at constant at99% CPU utilization.
Why would WCCP consume so much CPU on the Cisco 2851? By the way, I am only getting about 5Mbps download instead of 90Mbps download, I think because of the high CPU on the router?
we are using solarwinds as monitoring toll for all network devices..the solarwinds shows proper memory & cpu utilization for catalyst 3750 switches but shows hogh cpu/memory utilization values for 6509-vss...when we log into vss via cli the util & memory values are normal but same are very high on solarwinds..i have checked the solarwinds site also and fond that there was issue for 6509 related to high cpu in relase before 9.2 and 9.2 release of solarwind has resolved this issue..is anything to be checked on 6509 or as such any known bug in this regard for 6509-vss i am using software s72033-ADVIPSERVICESK9_WAN-VZ.122-33.SXI4A on my vss.
