how to resolve high cpu to interrupt.I am getting lots of input que drops in all vlan interfaces.I have enabled multicast in all vlan interfaces. System image file is "sup-bootdisk:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin"

We currently have 8 1242's and they all work fine, however we recently baught one 2nd hand one which was previously connected to a WLC, it lights up fine but it wont detect in IPSU even though the dhcp has assigned an IP to it. I would like to login through the web page to configure it but I am not able to do that either. It responds to ping fine though. So I no longer wont it be a LAP, so I tried to console in, to run flash_init etc. but when I try and give the <ESC> command (during the flash loader) it just carries on and ignores all input. I have used the correct settings Baud rate 9600, no parity, no flow control , databits 8, etc. but nothing happens it just goes through the boot and then asks me to press enter to input. i can then browse the directories and rename files. but I just cant get it to holt the loader so I can reset, I tried rename of config.txt and env_vars but that has't worked either. It keeps stating that it is looking for LWAPP/CAPWAP but unfortunately we don't have a WLC Is there another way I can reset it or is there some magic way in whic I can send the ESC command.

I've been digging into some performance issues on a LAN that has a couple of 2960s. The monitoring software I'm using has indicated a high amount of discarded outbound packets (up to 5%). The suggested resolutions were to enable flow control.
My question is does enabling flow control on all ports interrupt network traffic at all? this is a production network so I had already planned on doing it during off hours but also wanted to know if I should be prepared for any significant drop in traffic.
My company has an 881-w ISR that provides wireless and wired network functions for our small office (about 20 users). I was attempting to create a new V LAN (another story), and was able to create the V LAN (4) and assign it a new IP. However, when i came in today, and when i attempted to connect to the ISR, the serial console started spewing this over and over:
*Feb 8 13:31:32.479: %SYS-2-MALLOCFAIL: Memory allocation of 8 bytes failed from 0x81528DF0, alignment 0

[code]....
Now, I did leave the console session up overnight, as that's the only thing that I can think of. As expected, our service contract had expired. I did reboot the ISR, and I am looking to see if this can be fixed, or symptomatic of a larger issue, and time to replace? At this point i can't even get it to stop, and thus cannot log in.
Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running constantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.
View 6 Replies View RelatedWe installed a solution with 2 Cisco 2801, BGP multihomed failover.
1) The router which is currently getting all the traffic gets to 55% to 60% of CPU usage when handling 40 SIP/RTP streams . This equals 10Mbit up/10Mbit down and it showed around 5800 packets TX and around 5800 packets RX, with a majority of them CEF switched. As those figures are way less than the performance figures published by Cisco, we wonder if we made any mistake in setting up our router, or if we can do something to improve the router setup.
2) Does it have an impact on router performance if we increase/decrease RTP packet size, thus increasing or decreasing the pps relative to the consumed bandwidth?
3) If it is not possible to improve router configuration, we also wonder about possible replacement units for those routers. Would a 2901 do a good job? By how much would it rise the capacity? What other models would you recommend if we plan to rise the number of concurrent calls by a factor of 4 or even 8 times of what we have now (so up to 48000 pps and 80Mbit).
Here is what we tried:
- ip route-cache same-interface does not seem to improve anything
- ip flow ingress on or off makes no difference
- disabling the inbound ACL on fa0/0 seems to reduce load by 10%, although I don't understand why - a very high percentage is CPU interrupts, and ACLs are process switched, or not?
- we tried following the Cisco guide for high CPU due to high interrupts, with no success
Here are some usage statistics:
The graphs that we plot via SNMP show a propotional growth/increase of CPU and bandwidth (and thus pps) At the highest loads, we had a bit more than 55% CPU utilization with more than 50% interrupt CPU.

When they were not connected, the cpu utilization was normal.
I think it is because of SNMP gathering on LMS/NMS.
And I blocked arp table and forwarding table, but there was no change on cpu utilization. I couldn't find the bug reports and other references.

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've noticed a strange behaviour in my 2960s regarded to CPU.
CPU level is very high, 70-75% when nobody is logged by vty or console, but it drops drastically to 40% when sombebody logs in. I've been able to discover that this is due to CPU interrupt level, as it shows the output of sh process cpu sort 5sec, just logged in.

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?
