Linguagem imparcial

O conjunto de documentação deste produto faz o possível para usar uma linguagem imparcial. Para os fins deste conjunto de documentação, a imparcialidade é definida como uma linguagem que não implica em discriminação baseada em idade, deficiência, gênero, identidade racial, identidade étnica, orientação sexual, status socioeconômico e interseccionalidade. Pode haver exceções na documentação devido à linguagem codificada nas interfaces de usuário do software do produto, linguagem usada com base na documentação de RFP ou linguagem usada por um produto de terceiros referenciado.

Introdução

Este documento descreve o procedimento para recuperar a senha em XE-SDWAN.

Pré-requisitos

Requisitos

Não existem requisitos específicos para este documento.

Componentes Utilizados

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.

Problema

No XE-SDWAN (versão 16.10.3 em diante), há uma senha de administrador ocasional padrão devido a razões de segurança que podem ser facilmente ignoradas pelo usuário e podem potencialmente entrar em uma situação de bloqueio do usuário. Isso é especialmente perigoso durante a configuração inicial do roteador se a conexão de controle com o controlador vManage não estiver estabelecida; não é possível simplesmente anexar um novo modelo com o nome de usuário e a senha definidos. Este artigo fornece um procedimento detalhado sobre como recuperar.

Username: admin
Password:
Router#

Sep 23 20:36:03.133: SDWAN INFO: WARNING: Please configure a new username and password; one-time user admin is removed.

Esta é a nova mensagem no console após o login com as credenciais padrão de admin/admin.

Observação: este procedimento apaga a configuração atual, portanto, faça um backup da configuração, se possível, antes de prosseguir.

Solução

Este é um exemplo de como um dispositivo é bloqueado, pois ignora a mensagem de senha única dos registros de console:

Etapa 1. Inicie o processo com estas etapas:

Desligue e ligue o roteador e force-o a entrar no modo ROMmon com sequência de interrupção (ctrl+break, ctrl+c).
Altere o registro de configuração para 0xA102 ou 0x8000.

Observação: recomendamos 0xA102 porque ele é menos propenso a erros do usuário. Por exemplo, se você definir o registro de configuração por engano como 0x800 em vez de 0x8000 (dois zeros em vez de três), a taxa de baud do console será definida como 4800 em vez do desvio de configuração. Para obter mais informações sobre registros de configuração, consulte https://www.cisco.com/c/en/us/support/docs/routers/10000-series-routers/50421-config-register-use.html

Observação: No software Cisco IOS® XE, o desvio de configuração não pode ser feito com o registro de configuração 0x2142 porque o software Cisco IOS® XE SD-WAN armazena a configuração de uma maneira diferente no banco de dados de configuração (CDB) na flash. A partir do software Cisco IOS® XE SD-WAN 16.10.1, o bit 15 pode ser definido como 1 para ignorar a configuração, portanto o registro de configuração é, por exemplo, 0xA102. Este é um resultado do bit 15 at (0x8000) em combinação com o valor hexadecimal do registro padrão 0x2102.

3. Reinicialize a caixa (verifique a saída do comando):

Etapa 5. Agora, mais uma vez, você é solicitado a fornecer credenciais de administrador únicas. Após essa etapa, não se esqueça de alterar a senha padrão. É recomendável adicionar um usuário adicional também. Se você perder esta etapa e ficar bloqueado, então você precisa repetir todas as etapas novamente.
