Cisco Infrastructure :: High CPU Usage / Dropped Packets - Switch Blade WS-CBS3120X-S
Jun 25, 2012
I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
What is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).

My CAT 4510 switch is showing 99.9% CPU usage almost through out the day. After some analysis i saw that the “Cat4k Mgmt LoPri” process is having 86% CPU utilization. This process is a package that is including multiple process.
Within this package, two processes have been identified which are causing this shock which are “K5L3Unicast Adj Tabl” and “K5 L2 Hardware Addre” .
This indicates that some heavy activity is going on CEF adjacency table and RP MAC Address Table. My current IOS version is 12.2(53)SG

I'm seeing very high CPU usage on my new 3560CG-8-PC switch. It's at 61%. How to chase down what's causing it?
I'm seeing a lot of rpf-fail drops. What causes them? How to prevent?

The process "HL3U bkgrd proce" is causing high CPU usage issues in a switch 3750X-24T-L. The IOS is 15.0.2-SE2.
show platform ip unicast failed route and adjacencies displays a lot of entries, I've seen up to 1200.
After restart HL3U bkgrd proce takes around 10 - 20 % CPU, some hours later 99%.
A coupe of times we got logs like this:
%SYS-3-CPUHOG: Task is running for (2136)msecs, more than (2000)msecs (172/73),process = HL3U bkgrd process.

I have a strange error on my home network that I cannot find a solution to.I have an Huawei SmartAX MT882 from TalkTalk acting as a modem connected to a D-Link DSL-G624T acting as a router/switch. Connected to the D-Link I have a Windows 7 Pro machine (64-bit, SP1) and an XP (home i think) machine (sp 2 i think).The SmartAX modem is set up to perform DHCP and DNS relaying and the D-Link has DHCP turned off and DNS relay turned off.The Win7 machine can access the network, get an IP address and access the internet without problems, regardless as to the status of the XP machine.The XP machine can access the network, get an IP address and access the internet with no problems ONLY of the win7 is powered up. When the win7 machine is off, the XP machine seems to drop about 25% of the ping packets between it and the D-Link router and has no internet access (because of this i assume). [code]

I am using WAP4410N access point to connect 5 computer to the network. Recently the wireless network is very bad; pakets are often being droped, very high reply times. I have upgraded to the latest firmware tried to change configuration with no use i even tried the default configuration. I assumed that there's interference. I tried another AP ( linksys one) and things seems to be okay. what would be the problem with AP?

I am truly struggling with the changes after 8.21. I am trying to get a VPN up between two sites. This is the B end, I am sure there are a bunch of problems in the other end too. Eg. the tunnel NAT does not have the right priority 1.when I establish the tunnel I get this:
3 Sep 01 2008 11:23:37 Tunnel Manager has failed to establish an L2L SA. All configured IKE versions failed to establish the tunnel. Map Tag= outside_map. Map Sequence Number = 1.

I happen to noticed the FWSM was dropping packets at about 387 packets every 5 minutes. My outside FWSM is WAN facing and has a 1gig link (35% utilized) my inside facing has about 100 downstream switches to the closets. I do not see my 6509's back plane is being over utilized and my understanding of the FWSM show be go for 5 gig so it isn't oversubscribe. Why i am seeing packets dropped?

I notice that I have TX Packets Dropped only under the wireless section.This occurs when the wireless network is not in use also.I have tried many different channels, almost all of them.Im using wpa2-tkip+aes, mixed g and n network, auto 20/40, wps disabled.I understand about wireless interference also.wireless devices dont seem to have any issues though, not dropping from network.I usually get 4000 wireless TX drops a day. LAN and WAN show No TX drops

I have a problem with the 6500 not exporting netflow data. They are not exported due to no fib.I have read somewhere that this has something to do with VRF. VRF are running on the router.ip flow ingress has been applied to desired ip int.Is there anything I could do to make it export netflow data?

On one of our N7K, we have some packets dropped by the COPP policy in the class-default class-map. Partial results of "show policy-map interface control-plane" not so long after clearing the counters : [code]
what traffic is dropped by the policy ? Is there any logging possible ?

When a physical switchport/routed port has high usage, you can move the link to a higher capacity port, upgrade the port, bond links, etc. What exactly do you do when an SVI has high usage? I guess you could remove some servers from the VLAN, but that doesn't seem like a reasonable solution. What dictates the capacity of an SVI? The backplane of the switch?

I have a 1841 router plugged into a 100M Comcast ethernet connection. My router cpu is really high and users download speed isn't as high as before. Can a 1841 handle 100M circuit with 100 users on it? What would cause the router's cpu to be high? I don't think there are any viruses or malware on the lan.

I have a Cisco 1921 router and it uses 99% of CPU and i cant seem to spot wich process that is taking up the cpu. I have an interface with several sub-interfaces and i am moving data between two of those subnets, i tried the "ip route-cache same-interface"-command on giga bit ethernet 0/1 with all the sub-interfaces like gigabitethernet 0/1.18 and so on. That did not work.

Received this notice from ISP. Does this make sense:We have noticed we are getting a huge number of queries from X.X.X.X and it is showing to be about 98% of the DNS traffic hitting our name servers. It appears that the data consists of reverse lookups to 10.1.0.0 network. It needs to be remediated as soon as possible because it could cause a service interruption.It almost seems as if my router is acting as a DNS server. The isp data consists of reverse lookups to 10.1.0.0 network which would be the internal.

I have an Ironport S370 who is serving 30 users. The actual RAM usage is 78%, how should I check what processes are consuming the RAM?
I think this is the cause that the managemente console is much slower than some weeks before.

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.

I have configured an ASA 5510 and 2960S 48 port switch in a lab environment. I have two laptops connected to seperate subinterfaces with server 2003 as dhcp server for one network. Everything has been working fine as we have been testing the ASA while also testing the csc smm module. When we came in today we noticed the csc module cpu is running at 100% constantly and http traffic is extremely slow. I have not yet received my smartnet contracts from the vendor or I would open a TAC case and I have read on the net that this is a common problem.
