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 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.

Why packets overrun are incrementing on the ASA even when I've only 40Mbps of throughput traffic?All interface are 1000- Full Duplex, both on ASA and on Catalyst3750.I've test the ASA5540 generating GET HTTP, about 40Mbit of traffic.When I use one ingress interface and one egress interface, interface input overrun counter is zero.When I use the same traffic with 3 ingress interfaces(slot0) and 3 egress interfaces(slot1), interface input overrun counter increase(60k overrun in only 2 minutes).

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?

Showing Multiple MAC's On A Single Interface?

Mar 31, 2011

some of the servers are not pinging from one switch but they are pingable from other redundant distribution switch. So I took the IP addresses from the redundant switch, with that I found MAC addresses from the access switch.But when I tried to see to which ports these MAC are addresses are connected to, multiple MAC addresses are resolving to the same switchport. like 5 MAC's are showing to 1 port and other 3 MAC's are showing to other port, like this there are many. All these MAC's belong to virtual servers.

Cisco Switching/Routing :: Nexus 7010 OSPF Passive-interface Default Not Showing

Nov 6, 2011

I'm currently working on a plan to migrate our 6500's over to our new 7010's.  At the time of the migration I want to tighten up our OSPF design and configure OSPF for "passive-interface default" then allow only those interfaces that should have OSPF neighbors to send the hellos.  The issue is that the command is not showing up under the OSPF process.  What's even more interesting is that the Nexus 5.x Unicast Routing Configuration Guide shows that the "passive-interface default" command should be an option to enter.
 
I'm currently running version 5.1(4) (though looking to upgrade to 5.2 during my migration testing).  I would rather configure the passive-interface via the routing process versus having to enter it on every interface.
