    Switch Crash Trying to Use IP SLA Monitor

      As the title says. Has anyone else had a problem that would casue the network switch to crash/reboot.

      I was trying to set up a ICMP echa operation between two 6500 switchs. One of them crashed and rebooted.

              The problem is going to be determining if it is a problem with your 6500 or the software.

                  Well since Solorwinds support wont tell me can some one here tell me what the IP SLA Monitor puts on the switch's and router's so I can see where the conflict might have been?

                      Please post the details of your 6500 switch.
                      What supervisor module are you using, what IOS is it running?

                      There is a Cisco netflow bug that can cause these to crash....
                      "Crash due to Netflow DDTS CSCsq75944"

                          I just checked that bug on Cisco webpage and it says that my set up should have been safe to use it on. I will contact Cisco so they can either update the document or provide another fix. Thanks for all the help.

                              Just to contribute...

                               

                              I used the tool with a 6509 running VSS on IOS 12.2(17r)SX5, It certainly didnt cause my 6500's to reboot.  I setup maybe 10 echos, 2 DNS, 1 www, and 1 tcp connect.  The DNS SLAs acted a little strange where they would say it was down when it wasnt, but I am not ready as of yet to say its not something wrong with my DNS.  Here is an example of what it sets up on my switch when I create an echo and use the "show ip sla mon config"...

                              I am fairly new to IP SLA, I found it odd that there wasnt anything in show conf for the SLA.  But thats probably normal....?  :)

                        can you post your operations export (xml) so I can try in my lab and see if it is the operations that may be causing an issue.
