Dear friends,

On the 2960, i have two .bin images and i am pointing to the latest one.

However, the boot system flash: command along with the new image does not appear in the running config but it appears in the

show boot command.

Are you aware of any reasons for this?

Thanks a lot

   Thats normal behavior on smaller non chassis based switches like 2950,2960 ,3560 etc...   Don't know what the reasoning was behind that .  On some of ealier models like the 2950 it would only hold 1 image so it didn't matter.

Thanks a lot for the clarification Glen. I guess that should be the same with the 3750 too.

However, the 4948 switch shows the boot system flash: command in the running config too. Probably its because it uses a 4500 image.

Thanks a lot again

as suggested earlier its not been seen in small switches incase you would like to know the boot variable and things like that try "show boot "

this will tell you the boot variable, boot loader and configration registor.

Pretty usefull command

Hope that helps.
