%SYS-3-TIMERNEG:Error on Cat 4500 Switch

Hi,

I am getting this erro on my cat 4500 switch.:

Jul 4 10:11:11: %SYS-3-TIMERNEG: Cannot start timer (0x12589A8) with negative offset (-1983561290). -Process= "Cat4k Mgmt HiPri", ipl= 0, pid= 51

-Traceback= 10B45FA8 10B897F4 116B11C0 119ABC60 11DEA2D0 1177CA8 10E191D811A181D8 118ABABD 11B26B1D 1111ABD1 11B22D24 11B22D8D 118D6614 118D686D 118D6B44 1181712D

I looked at the bugs but could not find anything.

Software running is:12.2(52)SG

Any help would be greatly appriciated.

Thanks

Hi Neha,

This is a transitory issue which do not affect the operation of the switch.

Another customer had this issue by using the interface range command. The workaround was to explicitly use the exit or end keyword when you are done with the configuration.

Re: %SYS-3-TIMERNEG:Error on Cat 4500 Switch

Check the IOS version you are runnning. THere have been issues with the 4500 IOS when running

redundant sup's.  I ran into the same problem on a 4510R-E with redundant Sup6E. Although I was running a higher version of IOS, the issue is still present. From TAC I received the response in the bug CSCsx87562:

CSCsx87562    %SYS-3-TIMERNEG error following configuration change

Symptoms: The following error is seen following interface range configuration change:

%SYS-3-TIMERNEG: Cannot start timer (0xXXXXXXXX) with negative offset (-YYYYYYYYYY).

-Process= "",  ipl= 2

Conditions: This symptom is seen with dual supervisors installed and affects these Catalyst 4000 releases: 12.2(52)SG/XO, 12.2(50)SG4/5/6, 12.2(53)SG/SG1.

Workaround:

1- Configure the interfaces one by one.

2- Force a switchover "redundancy force-switchover".

3- Use Cisco IOS Release 12.2(50)SG3 until the fix code is released. There is still no information in which release this bug will be fixed.

After downgrading the IOS from 12.2(50)SG5 to 12.2(50)SG3, the supervisors were able to work properly again.

HTH.
