Goof Afternoon All,
I am using a Cisco 3945 Router, and when I 'Write Memory', the running config does not save to the flash.
I just updated to IOS version (3900-UNIVERSALK9-M), Version 15.4(3)M8
Configuration Register is set to 0x2102
the command 'copy run start' also doesn't work, however
the command 'copy run flash:' does work, This is slightly inconvenient for when other people make changes and think they saved it.
How would I go about fixing this?
