I used to put <boot system flash c2800nm-spservicesk9-mz.124-15.T8.bin> in the past.
But looking up the command lookup on boot system flash, it seems it shows it should be :
<boot system flash flash:c2800nm-spservicesk9-mz.124-15.T8.bin> instead.
But then from the router below it didn't really show the option to put the "flash: before filename it seems" so I am little hestiated which way should I put the command (with or without flash: after boot system flash).
router1(config)#boot system flash ?
WORD System image filename
My router is 2811 and 2801 with 12.4.15T8 SP services in it.
I think I read somewhere says the router to boot twice when flash: is not in the command but then if that is the case, the output didn't show we should enter the flash file system indicator then?
