Cisco WAN :: 6500 Make Crash And Go To ROMmon

Sep 11, 2012

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.

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.
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.

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.

Cisco Wireless :: / WiSM Crash With No Crash Log

Feb 21, 2012

I have many WiSM WLC's running One WLC was rebooted few days ago but there was no crash file and nothing in logs say why this issue happened.There was a power problem at the same time the WLC rebooted (some switches and PE's was rebooted as well) but if it is a power issue why only one WLC inside the WiSM rebooted and the other WLC is still working fine with no reboot?I have 5 WiSM modules connected to the same 6500 box, only one WLC was rebooted which indicates a crash but no crash file registered for it.Is there anyway I can find the reason why that WLC was rebooted?

Cisco WAN :: TAC 900 - Crash Because Of Large Packet

Dec 8, 2010

We are working on taking a port off of a switch and connecting it to a mux (TAC 900). Port is trunked to another switch in another geographic location. From wht I am being told from the engineer who handles the transmission end of things he said once our segment is physically connected the mux will crash. He supplied the error code to the vendor and they said it is crashing because of a jumbo packet in excess of 1536 bytes. Soon it will be a moot point as the hardware will be, upgraded but we need tis running NOW.

Cisco WAN :: BGP Peering Causes 7200 To Crash?

Apr 10, 2012

I have two 7204VXR with NPE-G2 and 1Gb of ram. One router has 2 eBGP peers and the other has 3. The routers receive all internet routes from the 5 peers and send 2 internal routes. There is an iBGP peering between both routers. On all peers I have a route-map to send only our routes.
All was working fine since a couple of months when I suddenly saw an increase of memory on one of the router (router B), 1 hour later the memory was 100% and router crash and reboot. The other router (router A) with the same hardware capacity, same ram and same amount of routes was working good. After router B restart, I shut all eBGP peering on it, keeping only iBGP with router A, ram used was the same as router A (about 50% used) but CPU was about 30% used by process Router BGP whereas router A which has active traffic and active eBGP is only 20% and bgp process i almost 0%. Restarting peers one by one on router B cause the same issue, increase of memory then crash, even with only one peer.
What I suspected :

- A peer on router B but I can't isolate one because the problem appears with each taken one by one

- Not enough memory,  but router A has the same number of routes and don't have any problem

- IOS version ? same on both 12.4.(15)T1

- Why process router BGP use 30% on router B when all eBGP peers are shut except iBGP and no traffic pass.

- A routing loop but I only send internal routes to peers and only have one iBGP session with no sync nor redistribution with an IGP
Of course I can't run any debu ip bgp on routers as the number of routes is very large (300K).

Cisco WAN :: ASR 1002 IOS And ROMmon Upgrade

Jan 10, 2011

I'm trying to upgrade the ASR 1002 we just purchased and am having some issues (this is a new device and is not in service).  I first tried upgrading the ROMMON using the upgrade rom-monitor filename bootflash:asr1000-rommon.150-1r.S.pkg all command, but the upgrade didn't seem to work completely.  When I do a sh platform I get the below output showing 15.0(1r)S: [code]
no valid BOOT image foundFinal autoboot attempt from default boot device...Rommon upgrade requestedMaximum upgrade attempts exceeded, continuing with old Rommon...
I've also tried upgrading the IOS, but that is not working either.  I tried "boot system flash:asr1000rp1-advipservicesk9.03.02.00.S.151-1.S.bin" command, but that did not work.  I made sure the image was good using the "verify" command and made sure to set "config-register 0x2102".  After I do a wr me and reload the router I get the below errors.

One Device Crash Down Entire Network

I am in charge of taking care our small office network (about 25 PC's) and encountered a problem the other day. I got a call that nothing network related was working. I went to look at the switches/router and everything appeared fine. After some troubleshooting i found if i unplugged the switch and connected directly the the router everything worked prefect. Reconnected the switch, network goes down again. I assumed it was the switch at first but then did a walk around and a laptop was in a weird frozen state. I unhooked the network cable and everything started working away like it should.

Cisco Switching/Routing :: 3560X Crash And Reboot On IOS 15.0(2)SE

Jan 24, 2013

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:
