Hi there,<br><br>I recently setup Ciscoworks to backup the cisco device configuration every day. Right now I configured 126 devices in CiscoWorks to be back up. But after Ciscoworks finished the scheduled backup job, I found my tac_plus process has been stopped automatically. I checked the tac_plus log and found the end of log file has one error:<br>
Fri Apr 2 08:20:28 2010 [3417]: Error 10.x.x.x: Bad sequence number 3 should be even<br>what does it mean?<br><br>Some devices got successfully telneted and get into the enable mode. But some devices failed. In addition, I found the below error, it seems the device is not reachable but the device didn't have any issue at that time. Is there any possiblity that the unexpected delay cause this issue? Can I adjust some kind of timeout parameter in tac_plus to be suitable for the situation?<br>
