[manish arora]

Hi All,

I am trying to backup the IOS from a Cisco 6506 SUP7203B but for some reason I am unable to do it for last couple days. I dont have access to the Smartnet for this Model so I wanted to save a copy of the IOS for a Backup.

Here;'s the Error that I am getting :-

6506-router01#copy sup-bootdisk: tftp:

Never Mind ... I figured it out ... It was more of an issues with the Linux server TFTP deamon.

FYI :- to fix this issue , stop xinetd process and just run tftp from usr/sbin.
