Catalyst Bus Error

Contents

If these error messages reoccur, reseat the supervisor engine blade. After you correct the anomaly, the messages cease. %AAAA-3-BADREG: Illegal registry call Message Displays This section addresses a Catalyst switch with MSFC that gets this message in the console or syslog: This indicates that a bad packet, probably a packet which contains a Layer 3 IP checksum error, was received and dropped. End with CNTL/Z.

This condition can occur because of a TCAM resource exception, a flow mask registers resource exception, or an unresolvable flow mask conflict with other NetFlow-based features. You must use a packet-sniffing application in order to detect these devices and track down the source address. If you see the error message only once or rarely, monitor the switch syslog in order to confirm that the error message is an isolated incident. Workaround The origin of the problem is external to the switch.

Troubleshooting Bus Error Crashes The first thing to do is to find out which memory location (also known as the "address" or "address operand") the router tried to access when the This output shows crashinfo recorded in the Supervisor Engine bootflash device. Workaround You can enable multicast rate limiting feature and set the threshold to a greater number.

This command is a compilation of many other Cisco IOS Software commands which includes: show version show running-config show stacks After a crash occurs, you must capture this information before a A software problem can cause these errors. Unsupported memory configuration Unsupported memory configuration Unsupported memory configuration Unsupported memory configuration Cat6k-MSFC2 platform with 0 Kbytes of main memory !--- The memory size is 0. *** Mistral Interrupt on line System Returned To Rom By S/w Reset Don't ask us how to subnet.

TAC will tell you what to do (reseat line cards) or tell you to RMA. crashinfo 2B745A9A C24D0 25 271437 Jan 27 2003 20:39:43 crashinfo_ 20030127-203943 After you have the crashinfo file available, collect the output of the show logging command and the show tech In general, if you see more than one parity error in a particular memory region in a relatively short period, you can consider it to be a hard parity error. The ECC that represents the parity error has been corrected by the system itself.

If QoS user based micro-flow policing is configured in this case, reflexive ACL disables NetFlow shortcut installation and traffic matching reflexive ACL is software switched.

TestCapture-The TestCapture test verifies that the capture feature of Layer 2 forwarding engine is working properly. From ROM Monitor, use the confreg command to change the configuration register to a setting, such as 0x2142, to ignore the router's configuration: rommon 1 > confreg 0x2142 You must reset System Returned To Rom By Address Error At Pc MSFC2 Crashes with a Parity Error The MSFC2 contains ECC memory protection. Bus Error Linux Keepalives are sent on the Catalyst switches in order to prevent loops in the network.

Refer to Processor Memory Parity Errors (PMPEs) for more information on parity errors. For DFC-enabled modules, the diagnostic packet is sent from the inband port of the supervisor engine through the switch fabric and is looped back from one of the DFC ports. cat6knative#dir bootflash: Directory of bootflash:/ 1 -rw- 1693168 Jul 24 2002 15:48:22 c6msfc2-boot-mz.121-8a.EX 2 -rw- 183086 Aug 29 2002 11:23:40 crashinfo_20020829-112340 3 -rw- 20174748 Jan 30 2003 11:59:18 c6sup22-jsv-mz.121-8b.E9 4 -rw- The error message can be one of these two types: C6KERRDETECT-2-FIFOCRITLEVEL: System detected an unrecoverable resources error on theactive supervisor pinnacle C6KERRDETECT-2-FIFOCRITLEVEL: System detected unrecoverable resources error on active supervisor port-asic "last Reload Reason Address Error At Pc"

After the RP gains control, initiate the break sequence. The checks are intended to help you maintain the desired and correct system configuration and functionality.

Reseat the supervisor and firmly insert it Once the supervisor comes online, issue the show diagnostic command in order to monitor the switch and check whether the error message still persists System Was Restarted By Bus Error At Pc http://danielhertzberg.wordpress.com - I blog about networks! In case of egress reflexive ACL, the reflexive ACL flowmask requirement is global on all the interfaces, since there is only ingress NetFlow.

We've tried different Supervisor 720-3B, a different chassis, another IOS version (12.2(33)), and yet I can't pinpoint the issue.

On EARL7-based switches, this limit is 1023. If you cannot session to the MSFC, contact Cisco Technical Support for assistance. Issue the clear line line_number command in order to clear obsolete sessions. Bus Error (load) Exception Router uptime is 2 days, 21 hours, 30 minutes System restarted by bus error at PC 0x30EE546, address 0xBB4C4 System image file is "flash:igs-j-l.111-24.bin", booted via flash .........

Then, resolve the issue with the source device or application. In this case, monitor the MSFC. I recently got a quote for 150 of them, with PoE for $150 a pop.

MSFC2 That Shipped Before November 2001 DRAM DIMM Location The MSFC2 has only one DRAM slot. You have other MISTRAL error messages that this section does not mention. But if the software does not support any of the line card features, these control messages are not recognized and the error message is displayed.

Workaround Reload the router in order to exit the exception mode. Rule #2: No Certification Brain Dumps / Cheating. Exceeded permitted 1000/100 intrs/msec Description This message indicates that the switch forwarding engine receives an IP packet of a length that is shorter than the minimum allowed length.
