Cisco Firewall :: ASA 5510 7.2.1 High Traffic On Outside Interface Very High Input?
Oct 13, 2011Today 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 RelatedCisco WAN :: 2801 High CPU Load / Low Traffic / High Interrupts
Nov 26, 2012We 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.
CPU utilization for five seconds: 36%/30%; one minute: 30%; five minutes: 30%

Cisco WAN :: 2811 - 99% CPU High IP Input?
Dec 8, 2011Our 2811 Edge router is having extremely high CPU problems. IP Input is consuming 70% of the process during business hours. Cisco express forwarding is enabled. It only shows 50% but its currently before business hours. Id say even 50% is still high.

Cisco Switching/Routing :: 3750 Stack With High CPU (IP Input)
Oct 1, 2011We added Site02 for redundancy and DR. Also added new SAN and ESX hosts. The CPU on device Site01Server01 is not very happy when files are being transferred between the sites. Since the setup is the same at both sites, why is the problem only at site01?
Site02 is newer and we have two 3750X-24 with IOS 12.2(55)SE3 on ipservices, for site02server01; no problem.

Cisco Switching/Routing :: Container High Load On 2611XM (MPC860P)
Mar 20, 2013I have a Cisco 2611XM (MPC860P) that i use at home, purchased it when i enrolled in my CCNA certification.
It never occured to me that i had an issue with this router. I have 10Mbps uplink at home, and sometimes its really slow, when i talked to my ISP, we did a lot of troubleshooting to see why we had high latency, but as it turns out, the issue is My Router.
I only have a few machines inside my local LAN so i never even thought this could happen. When i download a file using the 10Mb/s connection, the CPU load goes in less than 1 minute to 99%.
I thought it might be the IOS version of it, and upgraded it to a newer version, with the same results. Here is an output of it:

View 4 Replies View RelatedCisco WAN :: Input Errors On 1841 LAN Interface
Nov 4, 2011I use an 1841 router as an internet facing firewall with a 10MB MetroE connection. Lately users started reporting slow internet download speeds and web pages timing out. Bandwidth reports do not show the link as being saturated so I looked at the interfaces on the 1841. The interface connected to the provider shows OK as far as errors but the LAN side of the router shows steadily increasing input errors. It doesn't show any other errors, no CRC, frame, runts, giants or overruns, just generic input errors. What type of errors are those? Nothing is being logged on the console.
I moved the connection to another switch ports and the errors continue. I switched it down to 10MB and also changed the switch and the errors slow down but don't stop. Interestingly, the switch side never shows any errors. What can I do here? I guess it can be a bad interface but that is such a rare thing that I am hesitant to replace the router.
Cisco WAN :: 6500 - Input / Output Drops
Feb 7, 2011I have this topology in part of my networ:k
Cisco7200---Cisco6500---Cisco3560---LAN1
|
Cisco3560
|
LAN2
All devices are interconected via optical 1Gb/s links. There is no QoS implemented on any device and all VLANs are allowed on all interfaces.
Also all links are trunks (with many VLANs)
In LAN1 there was a layer 2 broadcast-storm and 4000packets/s was comming to rest of the network (in one particular VLAN).
1) 7200 with G1 should be able to handle traffic up to 500Mb/s, but a lot of users experienced drops on traffic via 7200.
(CPU load was around 10%).
2) Why do I have input drops on 7200 on link toward 6500 if CPU was normal. Broadcast comming to this interfaces were cca 4kpps. But since it's destination is not on router these packets should be rejected on interface controller. Is that right? (7200 doesn't even has dot1q subinterface in that VLAN but since 6500 allow all VLANs on its trunk these packets reach 7200)
3) Why do I have output drops on Cisco 6500 (it is here as layer 2 device only)? It is max 160Mb/s in output direction. It has WS6724 card with DFC (there is no oversubscription).. Shouln't 6500 send traffic as fast as interface allows (up to 1Gb/s). Am I righ't?
4) After all how coul'd 6500 now if 7200 can't handle these traffic?Output drops should be only seen if QoS is enabled (i.e. shaping), or if there is oversubscription on the linecard?

I have also connected all my other ethernet devices to the router so I don't have to keep unplugging them and replacing the ethernet cable in the wall socket. I can connect to the internet through the router but it's only allowing one device to be connected at once and the router is saying "no connection" even though I can connect through it. does this mean it's working as a switch at the moment, right? Would it be possible to make it work as a router so all my devices can work simultaneously and get the wifi to work?

Cisco :: 3560 Not Showing CRC And Input Errors In Logging
Oct 21, 2012I ran into a problem a few weeks ago and am still trying to figure out why either the 3560 switch or our Cacti syslog server did not alert us when one of our ports was experiencing heavy CRC and Input errors.
I had upgraded the IOS to 12.2(55)SE6 and rebooted the switch. About a week later, someone was troubleshooting why print jobs were having problems printing to a high speed printer. When I looked at the interface it showed a few thousand CRC and Input errors. I cleared the counters and had them print again and watched as the CRC and Input errors went up. When I did a "show log" there were no error messages. Looking at our Cacti Syslog there were also no errors present for the past 6 months.
We found that the device on the port was set to auto speed and duplex and the switch port was at 100/Full. Once we got them to match the problem was resolved, but we were left wondering why we never got any alerts.
We also have some 3548 and 3550 model switches that Cacti picks up %LINK-4-ERROR for any ports that show CRC and Input errors. I did some research and it appears that the 3560 switches do not have the LINK facility code. I believe it has been replaced with a PHY link code but I'm not sure. We do have some "%PHY-4-EXCESSIVE_ERRORS: Excessive FCS, data, or idle word errors found" but they are all for 3750 switches. I could not find any 3560 that had alerted for that error or the LINK error.
I also tripped port security on the 3560 switch just to make sure that it was reporting correctly to Cacti and that alert did show up.
My question is how do I get a 3560 switch to alert in the logging buffer for CRC/Input/FCS errors? Also, how I can generate CRC and Input errors on purpose for testing? I tried mismatching the speed/duplex/Auto and only got collissions, no CRC or Input errors.
