I need to upgrade the IOS on a 3845 router but I am not too sure of the procedure to do so.
I managed to upgrade the image on the NME-XD-48ES-2S-P(layer 2) which is the same for any native IOS switch but I am not able to do so for the L3 on the switch.
I cannot seem to find the doc on this IOS upgrade as well.
Can someone let me know the steps do the the upgrade on the 3845 router.
