Cisco WAN :: 6500 - Input / Output Drops

Feb 7, 2011

I 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?

Cisco Firewall :: 5580-40 - Input Errors / Overruns And Reset Drops On 10Gig Interface?

May 10, 2012

I have an issue with input errors, overruns, and input reset drops on the inside interface of an 5580-40 (v8.2.5: Transparent mode)  The box is not stressed at all according to the 'show' commands in the Cisco troubleshooting performance document for PIX/ASA v8.2.5.  Nothing stands out because is pretty much normal, nothing (processes, RAM, blocks, IO...) really being highly utilized.  I have replaced the 10Gig card and that seemed to work because the rate of errors has gone down tremedously.  The next step is to RMA the whole box.My question is what would be the cause of the inside interface to stop processing traffic (I say that because the syslog server stops receiving messages) for some periods of 30 seconds periodically throughout the day and clients lose their connections (ie Outlook, IBM Sametime, Oracle, MSSQL..etc).  Can the issue be somewhere related to the overruns and input errors?

Cisco WAN :: Input Errors On 1841 LAN Interface

Nov 4, 2011

I 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 :: 3560 Not Showing CRC And Input Errors In Logging

Oct 21, 2012

I 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.

Cisco Switching/Routing :: 3560G Input And Crc Errors Only On Built In Ports?

Mar 11, 2013

I have an odd situation where I cannot get a device connected to a built in switchport with out input and crc errors.  When connecting to a GLC-T sfp it works fine.Here is my test layout
 
Outdoor wireless AP --- 10' of cat6 cable --- Gigabit POE injector --- 10' Cat6 cable --- 3560G port 48.  (input and crc errors)
 
When I do this there are input and crc errors on the switch port.  This has been confirmed on three different switches and three different outdoor AP's.  We though at first it was the injector, but when we run the same setup, but instead connect the device to port 49 with a GLC-T sfp there are no errors.
 
Outdoor wireless AP --- 10' of cat6 cable --- Gigabit POE injector --- 10' Cat6 cable --- 3560G port 49 (GLC-T).  (No errors)
 
I have upgraded the 3560G to the latest ios and still it has the same problem.  If I run the same setup to a 2960 there are no errors at all.
 
Outdoor wireless AP --- 10' of cat6 cable --- Gigabit POE injector --- 10' Cat6 cable --- 2960 port g0/1  (No errors)
 
I have also tried manually setting the speed on the 3560G with no success.

Cisco Switching/Routing :: Output Errors On N5k 10G Interfaces?

Jan 9, 2012

today I witnessed a cisco n5k that stopped playing fair. For a yet unkown reason several interfaces started to show output errors all begining within the same second. While i instantly thought this would be a wiring issue I began to ask myself what an output error actually means. Google usually brings up output drops, not regular output errors. So what is it and how can a 10G fiber interface even detect that there is a problem without receiving what it was sending?

Cisco Switching/Routing :: SUP-7E - Input /output Rate Not Incrementing Under VLan

Mar 6, 2013

On my SUP-7E, when I issue a " show interface vlan X "  I cannot see the expected input/rate reflecting the real rate (which should be very high).
 
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 4000 bits/sec, 2 packets/sec

(Under the physical interfaces it is ok)However on other SUP-IV I can see the real rate.
 
My questions are :
 
- Why the SUP-7E does not reflect the rate, whereas the SUP-IV does ?

- I have heard about the 'counter' command under the vlan interface to activate the rate counters. Is this command application has any side effect on the switch ?

Cisco Switching/Routing :: RP / Input Drops On 6500 Sup 720 10GE

Jun 17, 2012

What does RP drops entail? We are experiencing 0.23 % drops on an vlan int on one of our 6500. This interface is an L3 to a server-subnet. Doing a sh int vlan 238 switching shows 30935411 RP (Route Processing) drops.It was a bit unclear to me in the thread "Input queue drops on 6500 vlan interface" if RP drops was through the router, or to the router(mgmnt)?I can do a netdr to see what traffic goes to it. It should not generate CPU load, but I think I will wait until after hours before I try that command.

- do NETDR:
-- debug netdr cap rx vlan 238

Cisco WAN :: Input Queue Drops On 6500 VLan Interface?

Dec 6, 2011

Vlan interface would be dropping packets on the input queue? Refer to the drops/flushes below.  This is from a 6500 with a Sup720, there are a number of vlans on it. This 6500 and it's HSRP partner are exhibiting the same symptoms on all the vlans I bothered to check.  This particular vlan is quite lightly used, there are only about fifteen user PC's (each with 100 Mb interfaces) on it.
 
There is a bit of information on input queue drops on Cisco, but this is focused on physical interfaces where I can understand some packets being dropped.  I would think that Vlan interfaces would have different issues.I note the "no buffer" errors as well, that also concerns me, especially as that counter is quite close to the "flushes".

Cisco WAN :: ASR 1001 Unexpected Output Drops

Jan 31, 2012

I have an issue with an ASR 1001. The problem occurs with MQC shaping applied to a gigabit interface in the outbound direction. The CIR of the provider we are using is 100Mb/sec, so we are shaping to that value. However when reported traffic levels are about 60Mb/sec, we see a steady increase in output drops. [code]
 
I have also tried increasing the hold queue, however this does not work with the drops. Increasing the shaping rate to 200Mb/sec gets rid of almost all the drops (not quite all!) but is not what we need. I think that we should see some drops when rates spike above 100mb, however the amount we are seeing seems excessive?
