  Different OS and switches . Thats the nature of the beast  for catos , you hit the enter key it is saved .    If the config mode on these switches is set to text then you would have to do a write mem to save , by default they are in binary so you do not unless set otherwise.

Hi glen

what is config mode and how can we change this to text in OS  switches.

also config mode on IOS  is text mode?

Hi Mahesh,

To change the text mode in Cat os use the command.

set config mode text nvram

You have to use the "write mem" to save the config, which will be saved in nvram.

You can also set the auto-save mode using the command
"set config mode text auto-save  " you can also specify a timer with this command to 
auto-save the config.

Yes, coonfig mode in IOS is text mode bydefault.
