A UCODE upgrade with forced reload results in a shorter reload time and downtime
for the switch or stack if the switch requires new UCODE with the new software.
If no UCODE upgrade is required after the software download, then the reload
proceeds as normal.
After a successful software download and upgrade, and if the UCODE upgrade is
necessary, the reload may be delayed by up to 20 minutes (though typically
less) in order to complete the UCODE upgrade. During this time, on the
supported switches, no new powered devices will be granted power, no new
power supplies will be recognized, and stack-power topology changes will not
be indicated on the console. All other switch functionality is unaffected.

Jak próbowałem bezpośrednio ze ściezki flash:/c3560-ipservicesk9-mz.150-2.SE8/c3560-ipservicesk9-mz.150-2.SE8.bin też to samo.

No bo IOS spodziewa się pliku w formacie tar a nie bin. Tu masz opis to wyjaśnione:
There are two types of files or file extensions that you see when you download 3550 software from the LAN Switches section of Downloads - Switches (registered customers only) .
The .bin file is the Cisco IOS® Software image. If you only want to use the CLI to manage the switch, the .bin file is the only file to download.
The .tar file is an archive file. The upgrade process extracts both the Cisco IOS image and the CMS files from the .tar file. If you want to manage switches or clusters of switches through a web interface, such as HTML, this file is the only file to download.
z tara poszło, jednak nie aktualizował microcodeca. Można w jakiś sposób wymusić aby SW raz jeszcze zaaktualizował MC, nawet jeśli jest ta sama wersja?
Microcode nie byl aktualizowany poniewaz nie bylo takiej potrzeby widocznie.
Nie mozna wymysic microcode upgrade, ale jak sie uprzesz i chcesz to mozesz zrobic downgrade do jakiejs starej wersji 12.2 i jeszcze raz upgrade do 15.
Pamietaj, ze zmiana microcode zajmuje okolo 20 - 30 min, downgrade + upgrade to w sumie okolo 1h.
Dlaczego tak w ogole chcesz upgrade microcode zrobic?
jak robie downgrade a później na nowo wersje 15 to nie upgraduje już microcode.
Chciałbym to zrobić, żeby sw zaczął poprawnie działać. Jak robiłem upgrade to podczas microcodu się wywalił i po restarcie, źle pokazuje statusy na diodach. Palą się np. wszytkie porty, pomiomo tego, że kabel nie jest do nich włożony. Jak podłącze kabel i odłącze to dioda ciągle się świeci.
