Introduction

Este documento descreve um problema raro e uma solução sobre os Catalyst 9000 Series Switches que não inicializam normalmente e caem no prompt do carregador de inicialização (switch:).

Problema

Recarregamento do chassi 2, motivo: falha na seleção Ativo/Em espera no modo 1+1.

switch: boot

attempting to boot from [flash:packages.conf]

Outra maneira de identificar esse problema é observar a variável de bootloader STACK 1+1 com o uso do comando set no modo bootloader. Para colocar o switch no modo bootloader, clique no botão mode enquanto o switch inicia a inicialização.

switch: set

ABNORMAL_RESET_COUNT=0

AUTOREBOOT_RESTORE=1

BOARDID=20569

BOOT=flash:packages.conf

BSI=0

MAC_ADDR=00:ab:cd:ef:01

MODEL_REVISION_NUM=D0

MOTHERBOARD_ASSEMBLY_NUM=73-17959-06

Solução

Desmarque a variável Stack 1+1. Depois que o switch conseguir inicializar 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_NUM=C9300-48UXM

MODEL_REVISION_NUM=D0

MOTHERBOARD_ASSEMBLY_NUM=73-17959-06

MOTHERBOARD_REVISION_NUM=A0

MOTHERBOARD_SERIAL_NUM=XXXXXXXXXXX

RANDOM_NUM=1901228755

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:

Quando a variável do carregador de inicialização Stack 1+1 estiver desconfigurada, emita o comando boot para que o switch possa inicializar a partir da variável de inicialização definida no switch.

switch: boot
