Cisco Switching/Routing :: 6500 - Reboot With Crash Info
Oct 25, 2012
Our 6500 was reboot by self with crash info and i found it was happened by CPU HOG. The log is below for CPU HOG and you can see many times from attached crash info file.
%SYS-SP-3-CPUHOG: Task is running for (16000)m secs, more than (2000)m secs (15/12),process = RPC pagp_switch_mp2sp.
[code]....
I think this process made high CPU & memory issue and then there were internal communication fail.. isn't it? So i need to know what PRC pagp_switch_mp2sp is to prevent next issue.

Got a problem with my 1760 router. Bought it from ebay and booted it on today and got this error,It has 180224K/16384K bytes of memory and 2 paritions of 32768K flash.I erased both partitions and put a different version of the IOS on (still 12.4) and there is no difference, still get the errors.These aren't on any of my other 1760 routers so I assume they are linked to the problem.

I have 3560X-24T-S switches with IP Services loaded at remote sites that I have been having troubles with. Originally, they had IOS 12.2(58)SE1 on them. I have up to four diverse paths via point-to-point microwave at the remote sites. The Microwave equipment is by Microwave Networks and is a Prodeus M series which Ethernet support. The original issue manifested itself as hardware loopback errors on some of the ports that were connected to the microwave links.
My experience in the past has been that when a hardware loopback error occurred it is usually a bad switch port. In this case however, if I disconnected all of the microwave Ethernet links and rebooted the switch and then connected the Ethernet connections to the microwave links again, everything works fine. No hardware loopback errors. That is, until the next switch reboot. Then the hardware loopback error would return. Interestingly, it would come back on different ports connected to the microwave links every time. So if a reboot was done without disconnecting the microwave Ethernet links the hardware loopback error would change from one microwave link to another after each reboot.
I then went through and read the lengthy release notes for IOS version 15.0(2)SE and found several fixes that I thought could fix my issue. So I downloaded it and updated a couple of the offending switches (not all of them were having this problem). After going through the second update required to resolve the 'open file error' that happens going between 12.2(58)SE1 and 15.0(2)SE the problem seemed to be resolved on the offending switches. So, I went ahead and updated the IOS on all of the switches with point-to-point microwave connections.
I now have one switch that was updated that is crashing and rebooting continuously when the Ethernet links for the point-to-point microwave are connected. Again, if I disconnect all the microwave links and reboot, it comes up fine ands stays fine when the microwave links are connected back up. It will work fine until the next reboot and then the crash and reboot loop starts over again. Below is a portion of the putty log when the crash occurs:

I have a WS-C3560X-24 and attached to that are some 9 acces switches, for some weeks now my 3560 reboots some time what couse that the other 9 switches are down for some minuts as well and i dont want this of course. the reboot happens at random times and some times one week not and then like yesterday afternoon it rebooted again.
when i check the Flash directory there is no crash file and when i look at the logging its clean and just shows the startup. it's not the powersuply it's redundend and more L3 switches are attached to this power source and they dont reboot.

The switch 6500-E is frequently crashing whenever the pm scp process reach 100% .I got it under the command "remote command switch show proce cpu".How to solve the problem. I opened the TAC and the engineer says to upgrade the image12.2(18) sxf.Is there any other work around that would avoid to reimage the switch and reloading.

I have a rare case. switch 6500 make crash and go to rommon. when review the crash appear that the switch charge the configuration from nvram, but, at the ending there are a few line command, that make the switch go to crash.. then I have to booting from rommon and start again. I use the version 12.2.33.sxi9 and 12.2.sxi3 and the configregister is 0x2102
I think that the switch get the startup-config file from other file-system.

We are running an FWSM on a 6509 with a SUP720. Firmware 3.2(18), in MultiContext Routed Mode, with shared MSFC.Everything runs fine on this baby most of them time, however occasionally without warning and with no specific pattern the Primary node will fail (as in completely stop responding) and the secondary will takover as active. Two get the primary up agian, I reset the hw-module and then no failover active on the secondary to return the primary as active. However, after this event, I start to experience strange issues with connectivity. Certain TCP src dst combinations will just not work.

I have a Cisco WS-C6513 switch, with a couple of GBIC module cards in it. I am trying to display the part number (or model number) of the modules which are inserted into this module card. How to do that? I don't want to schedule down-time to pull the module(s) - just to read the label! :-)
This shows me info for the "module card": sh module 9 But this doesn't work: sh module 9/6

We had an "Event" on our process network at the mill yesterday. I connected a new WS-C3560V2-48TS-S to our network and we lost communications with all of the other switches.
The core is a stack of 3 WS-C3750 switches, one is a -24TS-1U and the other two are -12S-S. These connect to 10 WS-C3560G-24TS and 5 Rockwell Stratix 8000 (IE3000) over fiber. I am planning on replaceing two 24 port switches with the new 48 port. I had the switch configured and running at my work bench. It was connected to the network with one sfp module and ran all weekend with no issues. Yesterday afternoon I took it to the network cabinet and installed it. I powered it up and connected two sfp modules to the fiber patch panel and made the connection at the core stack.
Everything looked OK. I had communication link lights working on everything. Within minutes, we lost communication with every switch connected to the core stack. I shut down the new 48 port switch and the network slowly came back up.
The new 48 port is configured with Flex Links for the fiber redundancy protocol and was connected to each of the 3750G-12S-S stack members.
I though it might have been a power issue but the stack is UPS protected and shows it has been up for over 10 weeks. I'm not even sure "Crash" is the best decription for what happened. The new switch has a high enough IP address that it would not take over as a IGMP Querier.

About an hour ago I had the master switch on one of my 3750x (WS-C3750X-48PF-S) stacks crash. The only two items we've found that could have caused this issue are the roughly 1.3 million big buffer misses and several of the following in the syslog
SLT:WARN:No exporter configured for smartlog! I do not have smartlogging turned on, nor is there a netflow exporter configured
sh logging smartlogsmartlog is disabledsmartlog exporter:smartlog pkt length: 64 Total pkts processed: 0Total DHCP Snooping pkts processed: 0Total DAI pkts processed: 0Total IPSG pkts processed: 0Total ACL pkts processed: 0
I did not see any traffic spikes prior to the crash.
This stack has been stable since it's last IOS upgrade from 12.2(58)SE1 to 12.2(58)SE2 back in October 2011 so this has me a little worried.

I am not able to find the exact bug for Cisco 3750E stack - Debug Exception (Could be NULL pointer dereference) Exception (0x2000) error. Closest i can find is CSCsa72400 which only affects ver 12.2(20)SE4.All the stacks (3 switches) are running 12.2(50)SE3, It appears that the switch 1 crashed and reloaded. My hunch is its software but i cant find any related bugs. It could be hardware issue as well ?

Problem I have encountered when upgrading a Cisco 6509 chassis with a new supervisor card from Sup2 to Sup 720b. The 6509 loads and then crashes completely, and when rebooted reloads into rommon.The same upgrade was performed on a similar switch with no apparent problems.

Our switch had a little crash-fest this morning at 2:30 AM. I did find a web page about diagnosing Software Forced Crash Exceptions, but it did not look like ours was one of the more easily-identifiable ones.
It may be worth noting that we've only used this switch for about a month, everything seemed fine until now. When we got the switch it did not have any GigE modules, and this week we put 2 into it and have been using them for 2 servers.
It looks like the switch was crashing repeatedly over a period of 20 minutes, and then it stopped and normalized. In the logs of the router that this switch uplinks into, we could see the ethernet port flapping during the time that the switch wasn't reachable.
Here's the Show Stack on the switch:

I am facing a problem with a cisco 6509 that goes into rommon every time i restart. If i give the command
rommon 1> boot
it will pick up the IOS on the sup-bootdisk: or bootdisk: and boots up but i dont understand why on reboot it wont pick up this IOS and boot itself and why do i have to write boot command everytime on rommon.
I have also explicitly given the command "boot system bootdisk:IOSNAME.bin" in the startup config file but still no luck.

We recently wanted to swap our existing WS-SUP720-base with a WS-SUP720-3B in a 6513 chassis.Had the existing configuration config saved in a txt file and replaced the supervisor. Booting went fine and we pasted in the original config. There was one failure message about unnsupported command but didnt take further notice."boot system flash sup-bootflash:" was probaly the line that the 720-3B didnt support.After wr mem and reload it went in continious loop and rebooting due to inncorrect boot device. Had to put back the old supervisor and have now the 720-3B in a 6504 chassis. Tried some commands in rommon, but are not getting any further.

I have 2 Catalyst 2960S-switches configured in a stack. The uplink is configured as a cross-stack etherchannel. Now I want to upgrade the stack with a minimum of downtime for the connected hosts. The hosts are connected to the stack via cross-stack etherchannels. So my question is: How can I upgrade the stack and reboot the members with a minimum of downtime? If I use the archive download-sw command with the /reload-option, the stack is reloaded and the result will be downtime for the hosts while th stack is reloading. Is it possible to upgrade the stack and then reboot the members one by one in a controlled manner?
