Recuperar um controlador Catalyst 9800 do modo ROMMON
Contents
Introdução
Este documento descreve como recuperar um controlador Catalyst 9800 baseado no modo ROMMON e nenhuma imagem na flash.
Pré-requisitos
Requisitos
A Cisco recomenda que você tenha conhecimento destes tópicos:
- Controladores sem fio Catalyst 9800
Componentes Utilizados
As informações neste documento são baseadas nestas versões de software e hardware:
- Catalyst 9800 versão 16.10.1
As informações neste documento foram criadas a partir de dispositivos em um ambiente de laboratório específico. Todos os dispositivos utilizados neste documento foram iniciados com uma configuração (padrão) inicial. Se a rede estiver ativa, certifique-se de que você entenda o impacto potencial de qualquer comando.
Configurar
Procedimento de recuperação de senha para o Virtual 9800 (9800-CL)
Etapa 1. Reinicialize o 9800-CL. Você verá rapidamente uma tela de seleção de inicialização:
Etapa 2. Pressione C nesta tela para obter o prompt do grub
Etapa 3. Você pode alterar o registro de configuração nesse prompt com o comando config 0x2142 comando
Etapa 4. Pressione a tecla ESC para voltar ao prompt de seleção de inicialização e selecione o comando packages.conf para inicializar na imagem normal.
Etapa 5. Sua WLC é inicializada sem configuração. Recuperá-lo.
Etapa 6. Não se esqueça de repetir o Procedimento da etapa 1 e de restaurar o registro de configuração ao valor original de 0x2002 para que a configuração seja salva e carregada após a reinicialização.
Procedimento de recuperação de senha para o dispositivo via ROMMON
Etapa 1. Envie a tecla 'break' quando vir ##### imprimir no console do sistema que carrega a imagem. Em seguida, o sistema interrompe o processo de inicialização e vai para o prompt do ROMMON. Você pode fazer isso ao pressionar break ou ctrl+break no teclado. Você também pode enviar a interrupção do programa de terminal (por exemplo, Comando Especial Putty > Interromper, Controle do Teraterm > Enviar Interrupção).
Cuidado: a recuperação de senha exige que o sistema seja liberado para o ROMMON. No Cisco IOS® clássico, a definição config-register determina se o sistema pode retornar ao ROMMON. Um registro de configuração de 0x2102 impediria o retorno ao ROMMON quando "break" fosse emitido. Por padrão, todos os dispositivos 9800 (9800-40, 9800-80, 9800-L) têm o conjunto de registro de configuração 0x2102. No entanto, como eles executam o Cisco IOS-XE® baseado em Linux, isso é ignorado e a única maneira de impedir o retorno ao ROMMON é configurar o comando "no service password-recovery".
Aviso: no 9800-L que executa o ROMMON anterior ao 16.12(3r), esse bit no registro de configuração impede a 'interrupção' no ROMMON para fazer a recuperação de senha.
Correção: se você executar um ROMMON mais antigo, atualize o ROMMON com as instruções documentadas em: Upgrade Field Programmables for Cisco Catalyst 9800-L Wireless Controller
Solução alternativa: se a atualização não puder ser feita, modifique o registro de configuração para 0x2002 como uma solução alternativa e evite o bloqueio do ROMMON.

Etapa 2.Altere o registro de configuração para 0x2142 com o comando confreg 0x2142 do prompt do ROMMON.
rommon 1 > confreg 0x2142 You must reset or power cycle for new config to take effect
Etapa 3. Para salvar a alteração de configuração do rommon, execute sync no prompt rommon, reset rommon para alteração aplicada do prompt rommon.

Etapa 4. Agora o sistema inicializa sem nenhuma configuração. Ignorar o assistente de configuração de inicialização.
Etapa 5. Quando o sistema ficar ativo, copie startup-config para running-config.
Etapa 6. Reconfigure a senha de ativação ou as credenciais de login e verifique se você pode acessar o dispositivo via telnet ou ssh.
C9800-40#telnet 172.22.175.1 Trying 172.22.175.1 ... Open User Access Verification Username: admin Password: C9800-40#
Passo 7. Altere o config-register de volta para 0x2002.
C9800-40(config)#config-register 0x2002
Observação: não use 0x2102. Com 0x2102, você não tem mais permissão para enviar uma pausa.
Etapa 8. Salvar configuração.
C9800-40#write memory Building configuration... [OK]
Procedimento de recuperação de senha para o dispositivo via USB
Inicialize o WLC a partir do ROMMON
Se você ficar preso no ROMMON e a inicialização não funcionar:
rommon 12 > boot File size is 0x0001dfe6 Located memleak.tcl Image size 122854 inode num 12, bks cnt 30 blk size 8*512 ## Boot image size = 122854 (0x1dfe6) bytes Unsigned package found, aborting package loading...

Você pode recuperar a caixa:
- Carregando uma imagem através de uma pen drive USB.
- Carregando uma imagem através de Gigabit0 (interface de gerenciamento fora de banda).
Carregar imagem por USB
Etapa 1. Tenha um pen drive USB com o arquivo .bin para ser carregado no controlador 9800. (no 9800-80, devido ao bug da Cisco ID CSCvn8287, uma unidade flash USB 3.0 não pode ser reconhecida no ROMMON). Observe que o procedimento é o mesmo no caso de um 9800-CL virtual, mas você pode ter que conectar a unidade USB no VMhost e mapeá-lo para a VM.
Etapa 2. Conecte o driver USB à porta USB 0 do 9800.
Visão frontal:
Etapa 3. Faça login do console para o controlador e verifique se ele consegue ler o USB.
rommon 19 > dir usb0: File System: FAT32 ! !--Output omitted-- ! 335644 1009389904-rw- <filename>SSA.bin
Etapa 4. Configure o 9800 para ser inicializado a partir da imagem USB.
rommon 21 > boot usb0:
.bin
Located qwlc-universalk9_wlc.BLD_V169_THROTTLE_LATEST_20180601_191011.SSA.bin, start cluster is 335644
########################################################################################################
########################################################################################################
########################################################################################################
Etapa 5. Depois que o 9800 for executado, copie a imagem do USB para o booflash:
WLC# copy usb0:
.bin bootflash:
Destination filename [qwlc-universalk9_wlc.BLD_V169_THROTTLE_LATEST_20180601_191011.SSA.bin]?
Copy in progress...CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
Etapa 6. Altere o 9800 do modo de pacote para o modo de instalação.
Quando você inicializa o controlador a partir de um USB, ele é inicializado no modo de pacote:
! !--Output omitted-- ! FIPS: Flash Key Check : Key Not Found, FIPS Mode Not Enabled Processor board ID TTM22071510 1 Virtual Ethernet interface 4 Ten Gigabit Ethernet interfaces 32768K bytes of non-volatile configuration memory. 33554432K bytes of physical memory. 26910719K bytes of eUSB flash at bootflash:. 234365527K bytes of SATA hard disk at hard disk:. 15243680K bytes of USB flash at usb0:. 0K bytes of WebUI ODM Files at webui:. Base Ethernet MAC Address : 00:A3:8E:23:A2:40 Installation mode is BUNDLE %INIT: waited 0 seconds for NVRAM to be available
A partir da versão 16.12, na interface do usuário, você pode optar por ir para o modo INSTALAR na próxima atualização. Forneça qualquer arquivo de software, que inclua a versão atual para mover para o modo INSTALAR.
Passo 7. Edite a variável de inicialização se ela não apontar para um arquivo packages.conf.
WLC#configure terminal Enter configuration commands, one per line. End with CNTL/Z. WLC(config)#no boot system WLC(config)#boot system bootflash:packages.conf WLC(config)#end WLC#write Building configuration... [OK] WLC#show boot BOOT variable = flash:packages.conf,12; CONFIG_FILE variable does not exist BOOTLDR variable does not exist Configuration register is 0x2102 Standby not ready to show bootvar
Verifique se o registro de configuração é 0x2002.
Etapa 8. Recarregue a WLC:
WLC#reload
Depois disso, o controlador é inicializado no modo de instalação.
WLC#show version
! !--Output omitted-- !
Installation mode is INSTALL Configuration register is 0x2002
Carregar uma imagem do TFTP
Para carregar uma imagem da rede, você deve ter a porta de gerenciamento GigabitEthernet0 conectada fisicamente a uma porta de acesso.
No ROMMON, você pode verificar as variáveis a qualquer momento com o comando set.
rommon 1 > set PS1=rommon ! > ?=0 DEFAULT_GATEWAY=10.1.1.1 ETHER_SPEED_MODE=4 TFTP_RETRY_COUNT=36 SWITCH_NUMBER=1 DLC_DONE=TRUE RET_2_RTS= RET_2_RCALTS= MCP_STARTUP_TRACEFLAGS=00000000:00000000 TFTP_MACADDR=00:db:ad:ba:d0:52 IP_SUBNET_MASK=255.255.255.0 IP_ADDRESS=10.1.1.152 TFTP_SERVER=10.1.1.1 TFTP_FILE=C9800-80-universalk9_wlc.BLD_V1610_1_THROTTLE_LATEST_20181016_174328_2.bin BSI=0 RANDOM_NUM=1650632109
Em seguida, você pode definir as variáveis uma a uma. Não há necessidade de digitar set antes do nome da variável como você faz para outros dispositivos ROMMON. Evite erros de digitação ao digitar o nome da variável, pois não há verificação de nenhum tipo.
rommon 2 > IP_ADDRESS=10.48.71.113 rommon 3 > IP_SUBNET_MASK=255.255.255.128 rommon 4 > DEFAULT_GATEWAY=10.48.71.5
Quando as configurações IP estiverem estabelecidas, você poderá inicializar a partir de uma imagem TFTP com o próximo comando:
rommon 5 > boot tftp://10.48.39.33/C9800-80-universalk9_wlc.16.10.01.SPA.bin
IP_ADDRESS: 10.48.71.113

Você termina na linha de comando do Cisco IOS. Não se esqueça de copiar a imagem do Cisco IOS para a flash ou para o disco rígido e definir corretamente a variável de inicialização. Você pode continuar o procedimento a partir do USB, anterior à etapa 6, depois que o arquivo for copiado na memória flash ou no disco rígido:.
