2960 IOS Upgrade from 12.2(46) to 12.2(58)SE1 using ciscoworks or any TFTP server

[venkata dandu]

Hi There

    Thanks in advance. We are trying to upgrade all our 2960 switches to the same image [12.2(58)SE1] using ciscoworks. Switches running image 12.2(55) are successfully getting upgraded but switches running 12.2(46) are failing half the way during the process of transfering the image. It fails even when i try it using CLI by connecting to the switch using telnet/ssh copying the image from a TFTP server.

    It successfully upgrades only when i try the same by connecting using a console cable. Is there any known bug or is there anything wrong in the process i was doing?

Regards;

Rams

  Check for bugs on with the 12.2.46 version . Sounds like a IOS issue  if 12.2.55 works .
