識別此問題的另一種方法是在開機載入器模式下執行set命令以檢視STACK 1+1開機載入器變數。若要使交換器進入開機載入器模式，請在交換器開始開機時按一下「mode」按鈕。

解決方案

取消設定Stack 1+1變數。之後，此交換器可以正常啟動。

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_NUM=C9300-48UXM

MOTHERBOARD_ASSEMBLY_NUM=73-17959-06
MOTHERBOARD_REVISION_NUM=A0

RET_2_RCALTS=
ROMMON_AUTOBOOT_ATTEMPT=3
SWITCH_IGNORE_STARTUP_CFG=1
SWITCH_NUMBER=2
SYSTEM_SERIAL_NUM=XXXXXXXXXX
TEMPLATE=access
VERSION_ID=V01

switch:

取消設定Stack 1+1開機載入程式變數後，執行boot指令，以便交換器可以從交換器上設定的開機變數開機。
