Recupere um controlador Catalyst 9800 ou a senha do modo ROMMON
Contents
Introduction
Este documento descreve como recuperar uma controladora Catalyst 9800 baseada no modo ROMMON e nenhuma imagem na flash.
Prerequisites
Requirements
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 v16.10.1
As informações neste documento foram criadas a partir de dispositivos em um ambiente de laboratório específico. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Configurar
Procedimento de recuperação de senha para Virtual 9800 (9800-CL)
Etapa 1. Reinicie o 9800-CL. Você deve ver rapidamente uma tela de seleção de inicialização
Etapa 2. pressione 'c' nesta tela para obter o prompt de inicialização
Etapa 3. Você pode alterar o registro de configuração nesse prompt com "confreg 0x2142". comando
Etapa 4. Pressione a tecla 'esc' para retornar ao prompt de seleção de inicialização e escolha "packages.conf" para inicializar na imagem normal.
Etapa 5. Sua WLC será inicializada sem configuração. Recuperá-lo
Etapa 6. Não se esqueça de repetir o Procedimento na etapa 1 e de restaurar o registro de configuração para o valor original de 0x2002 para que a configuração seja salva e carregada durante as reinicializações.
Procedimento de recuperação de senha para o equipamento via ROMMON
Etapa 1. Envie a tecla 'break' quando você vir #### print no console para carregar a imagem do sistema.Em seguida, o sistema interromperá o processo de inicialização e irá para o prompt rommon. Você pode fazer isso pressionando break ou ctrl+break no teclado ou enviando break do programa de terminal (ex: Comando Putty Special -> Break, Controlo Teraterm -> Enviar Break

Etapa 2.Altere o registro de configuração para 0x2142 usando o comando "confreg 0x2142" do prompt 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 rommon, execute "sync" no prompt rommon, "reset" rommon para a alteração aplicada no prompt rommon.
rommon 2 > sync
rommon 3 > reset

Etapa 4. Agora o sistema será inicializado sem nenhuma configuração, ignore o assistente de configuração de inicialização.
Etapa 5. Quando o sistema for ativado, copie startup-config em running-config.
Etapa 6. Reconfigure a senha de ativação ou as credenciais de registro 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 registro de configuração de volta para 0x2002
C9800-40(config)#config-register 0x2002
AVISO: Não use 0x2102. Com 0x2102, talvez você não tenha mais permissão para enviar pausa.
- save config (salvar configuração).

Procedimento de recuperação de senha para o equipamento via USB
Inicialize a WLC 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...

E o flash não tem nenhuma imagem a partir da qual inicializar:
rommon 13 > dir bootflash: File System: EXT2/EXT3 11 16384 drwx------ lost+found 850305 4096 drwxr-xr-x .installer 588673 4096 drwxrwxrwx .prst_sync 948417 4096 drwxr-xr-x .rollback_timer 1381745 4096 drwxr-xr-x dc_profile_dir 12 122854 -rw-r--r-- memleak.tcl 506913 4096 drwxr-x--- vman_fdb 670433 4096 drwxr-xr-x .dbpersist 793073 4096 drwxr-xr-x onep 13 35 -rw-r--r-- pnp-tech-time 14 109887 -rw-r--r-- pnp-tech-discovery-summary 15 616 -rw-r--r-- vlan.dat
Você pode recuperar a caixa:
- Carregando uma imagem por meio de uma unidade USB
- Carregando uma imagem através de Gigabit0 (interface de gerenciamento fora de banda)
Carregar imagem por USB
Etapa 1. Possuir uma unidade de caneta USB com o arquivo .bin a ser carregado na controladora 9800 (no 9800-80, devido ao CSCvn82287 
, uma unidade flash USB 3.0 pode não ser reconhecida no ROMMON). Observe que o procedimento é o mesmo no caso de um 9800-CL virtual, mas você terá que conectar a unidade USB no VMhost e mapeá-la para a VM.
Etapa 2. Conecte o driver USB à porta USB 0 do 9800
Vista frontal:
Etapa 3. Faça login pelo console para a controladora e verifique se ele pode 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. Quando o 9800 estiver ativado, copie a imagem do USB para a barra de tarefas:
WLC# copy usb0:
.bin bootflash:
Destination filename [qwlc-universalk9_wlc.BLD_V169_THROTTLE_LATEST_20180601_191011.SSA.bin]?
Copy in progress...CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
Etapa 6. É melhor alterar 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 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 harddisk:. 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
Na interface de usuário da Web, a partir do 16.12, você pode optar por mover para o modo INSTALL na próxima atualização (fornecer qualquer arquivo de software, incluindo a versão atual para mover para o modo INSTALL)
Passo 7. Edite a variável de inicialização se ela não estiver apontando para um arquivo "packages.conf"
WLC# conf t 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. Recarregar 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 digitando "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
Você pode então definir as variáveis uma por uma. Não há necessidade de digitar "set" antes do nome da variável, como em alguns outros dispositivos ROMMON. Certifique-se de não fazer nenhum erro 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 de IP estiverem definidas, você poderá inicializar a partir de uma imagem TFTP com o seguinte comando:
rommon 5 > b tftp://10.48.39.33/C9800-80-universalk9_wlc.16.10.01.SPA.bin
IP_ADDRESS: 10.48.71.113
IP_SUBNET_MASK: 255.255.255.128
