Cisco Switching/Routing :: Meaning Of Crash Log Cat6500
Jan 1, 2012
What this crash means? This is a 6509 with a single Sup720 Cisco IOS Software, s72033_rp Software (s72033_rp-ADVIPSERVICESK9_WAN-M), Version 12.2(33)SXI, RELEASE SOFTWARE (fc2)System returned to ROM by s/w reset at 04:42:07 PST8PDT Mon Jan 2 2012 (SP by bus error at PC 0x40C6681C, address 0x424B).
c2950-i6q4l2-mz.121-22.EA10a.bin is the image name of the 2950 switch i have in my office. what is the meaning of " i6q4l2 "? I saw some IOS like IP base, adv-security. but i didn't see anything like this before.
let me know the exact meaning of attach ( yellow marked one)? the contractor was saying "it doesn't mean two switches as there is a built in redundancy in Cisco switch)"I don't think he is correct as I never heard about built in redundancy in Cisco Router/switchAny comment as this will affect the numbers from 55 (3750 v2) to 110....
how to clear vty line? Please see below. A sh tcp <line number> shows that the TCB is waiting for TCP Process. The TCP processs TCB is waiting for is SSH. I believe because of this ssh process still running, the vty line cannot be cleared.

Using the new SUP-2T, need to clarify one query. If we are using the new SUP-2T in VSS mode, will the new ASA service module and NAM-3 are supported? From Cisco site, ASA module FAQ:
Q. Will the ASA Services Module support the Cisco Catalyst Virtual Switching System (VSS) at FCS?
A. Yes, depending on which supervisor you use. The ASA Services Module supports VSS either as a single firewall or as a failover pair of firewalls, when used with the Supervisor 720-10G (VS-S720-10G-3C and VS-S720-10G-3CXL). Transparent and multi- context modes also work with the VSS in this configuration. However, though the SUP 720-3B (WS-SUP720-3B and WS-SUP720-3BXL) is supported by the ASA Services Module, it is not capable of supporting the VSS. No reference to Supervisor-2T.
We have IP device on the farm switch(cat6500, which is an access layer siwtch), with the gateway on the core switches (Nexus7000), on the core when I do show ip arp, I found the mac.But when I do sh mac add add of that mac there is no port attached to that mac.
Since that particular vlan only resides on the cat 6500 and two cores, so I logged in to the 6500, and when I show mac- in that vlan, I didn’t find that mac addresss. Instead, I found another mac address with last 8bit are the same of that mac.
Is it some kind VIP of the mac? How so, if no port, how can the switch forward the frame? [code]
I am having problems with IGMP and QoS on CAT6500 platform with SUP720 engine.The problem is, it seems that all IGMP packets are getting marked with DSCP 48 when sent out of the switch regardless of any input service policy. I found several articles saying that PFC QoS does not apply to IGMP packets. However in IOS 15 that should be possible, but I didn't get it to work there either. [code]
I recently rebuilt the configuration of our Cat6500 multilayer device for use as a user stack. The device is funtioning as it should be, but I am unable to set SSH using the 'crypto key generate rsa' command. The crytop command isn't avaiable at all, which suggests a firmware issue.
I have configured a hostname and Ip domain-name and the image is the only one available.

i have a campus network with 2 core Cat6500 and multiple 4500 series distribution switches plus 2960 series access switches,we have deployed IPTV system in the network but currently 50 TVs are working through sattelite stream from streaming server Cisco's DCM 9900.we are planning to add more 300 TVs in the network and i am wondering that when all of them will be deployed then what will happen for switches cpu utilizations when all the Tvs will be running on the same time with different different channels.
If I monitor a trunkport on the rootbridge in both directions I get Duplicate Multicast Packets on the perticular VLAN. The first guess is, that this is worked as designed and not a IOS Bug (Platform CAT6500 SUP720 IOS 12.2(33)SXI9 ) Until know I only found an old Cisco press link from 2002 with this subject.
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:

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.
I have a cisco 2821 router in rommon and displaying the message '' softwre forced crash '' and '' checksum error'' .I tried to do rommon tftpdnld but as the image is self decompressing into the ram it again crashes with the same error although i have done it with various valid ios but in vain.
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 got some unexpected System crash, and this happens to 2 different routers on the same network.. (We suffer a Crash and change the router, happens the same to the new router after some time, maybe 40 minutes!!)
Here is the last console report for the new router....
Preparing to dump core... 4w1d: %SYS-2-WATCHDOG: Process aborted on watchdog timeout, process = IP NAT Age
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.
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.
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.

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.

I have one Catalyst 6509E chassis and two SUP720. The bootup sequence on SUP 720 (standby hot) failed . Messages that appear on SUP 720, on the console port indicate o software crash. I don't have a flash card in SUP720.

I have many WiSM WLC's running 188.8.131.52. 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?
