Per identificare questo problema, occorre anche esaminare la variabile bootloader STACK 1+1 con il set comando in modalità bootloader. Per avviare lo switch in modalità bootloader, fare clic sul mode pulsante all'avvio dello switch.
switch: set
ABNORMAL_RESET_COUNT=0
AUTOREBOOT_RESTORE=1

Soluzione
Annullare la variabile Stack 1+1. Dopodiché, lo switch può avviarsi normalmente.
switch:unset STACK_1_1
switch: set
ABNORMAL_RESET_COUNT=0
AUTOREBOOT_RESTORE=1
BOARDID=20569
BOOT=flash:packages.conf
BSI=0
MAC_ADDR=00:ab:cd:ef:01
MANUAL_BOOT=yes

MODEL_REVISION_NUM=D0

ROMMON_AUTOBOOT_ATTEMPT=3
SWITCH_IGNORE_STARTUP_CFG=1
SWITCH_NUMBER=2
SYSTEM_SERIAL_NUM=XXXXXXXXXX
TEMPLATE=access
VERSION_ID=V01
switch:
Dopo aver disattivato la variabile bootloader Stack 1+1, usare il boot comando in modo che lo switch possa avviarsi dalla variabile di avvio impostata sullo switch.
switch: boot
