Introdução

A implementação de rechamada do Microsoft não é complacente com RFC 1570leavingcisco.com . Contudo, devido à grande participação no mercado do cliente da rede de comunicação dial-up de Microsoft, Cisco executou o protocolo de controle da rechamada Microsoft (MSCB) no Software Release 11.3(2)T e Mais Recente de Cisco IOS�.

Pré-requisitos

Requisitos

Antes de você tentar esta configuração, verifique se estes requisitos são atendidos:

  • Configurar o servidor do acesso de rede (NAS) para aceitar chamadas analógicas do cliente. A rechamada é uns recursos adicionais do discado do modem. , Verifique consequentemente se este aspecto funciona corretamente. Isto pode ajudá-lo a pesquisar defeitos.

  • O circuito T1/E1 deve ser capaz da discagem. Contacte sua companhia telefônica (telco) para verificar isto.

Componentes Utilizados

A informação neste documento é baseada em versões de Cisco IOS Software Release 11.3(2)T e Mais Recente.

Esta encenação foi testada em um PC com rede de comunicação dial-up de Windows.

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 você estiver trabalhando em uma rede ativa, certifique-se de que entende o impacto potencial de qualquer comando antes de utilizá-lo.

Convenções

Para obter mais informações sobre convenções de documento, consulte as Convenções de dicas técnicas Cisco.

Material de Suporte

A rechamada executa nesta ordem:

  1. Um usuário de PC (cliente) conecta ao Cisco access server.

  2. O processo de chamada de volta é negociado na fase do protocolo de controle de link (LCP) do Point-to-Point Protocol (PPP).

  3. A autenticação de PPP é executada.

  4. O Cisco IOS Software valida regras da rechamada para esta usuário ou linha e desliga o chamador de rechamada.

  5. O Cisco access server disca o cliente.

Há quatro tipos de MSCB:

  1. Nenhuma rechamada.

  2. Número de rechamada específica de usuário.

  3. número de chamada de volta (preconfigured) Server-especificado.

  4. Lista de número de chamada de volta preconfigured.

A configuração padrão não é nenhuma rechamada (opção 1). As opções 2 ou 3 podem ser configuradas:

  • Localmente (se nenhum servidor AAA é usado).

  • No TACACS+ ou no perfil de usuário radius (se o AAA é usado).

Se a opção 2 é configurada, o usuário está alertado entrar em seu número de chamada de volta. Se o option 3 é configurado, a alerta oferece somente uma escolha, que é o número administrador-definido.

Cisco executa somente a funcionalidade do servidor de chamada de volta do MSCB e não da funcionalidade da chamada de volta ao cliente. Isto significa que um roteador Cisco pode ser usado somente como um servidor MSCB e não como um MSCB cliente. Além, a implementação Cisco do MSCB exige a autenticação ser executada no cliente.

Configurar

Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.

Resumo da configuração

Para permitir o MSCB, você deve permitir o comando ppp callback accept sob a relação de recepção (por exemplo, grupo assíncrono). Além, porque a autenticação é exigida, você deve permitir o protocolo password authentication (PAP) ou desafiar a autenticação do protocolo de autenticação de cumprimento (RACHADURA):

ppp authentication chap pap

Dois scripts de bate-papo são criados automaticamente. Estes são o scripts de bate-papo do fora do gancho e da rechamada:

chat-script offhook "" "ATH1" OK
chat-script callback ABORT ERROR ABORT BUSY "" 
"ATZ" OK "ATDT \T" TIMEOUT60 CONNECT \c

O scripts de bate-papo é aplicado igualmente automaticamente às linhas no uso:

line 1 24
  script modem-off-hook offhook
  script callback callback

Um usuário deve ser autorizado ser chamado para trás. Você pode configurar este localmente no NAS ou no servidor AAA externo (RAIO ou TACACS+), com base em onde a informação do nome de usuário e senha é armazenada.

Esta é uma configuração local para um usuário que seja chamado para trás em 5551212:

username callmeback callback-dialstring 5551212 password cisco

Esta configuração local é aplicável aos usuários são permitidos que especificar seu próprio número de chamada de volta:

username callmeback callback-dialstring "" password cisco

Configuração do Window Client

Configuração do cliente Windows 95 e 98

Para Windows 95 e 98 PC, não há nenhuma configuração para callback especial do lado do cliente. O servidor de acesso trata os recursos de chamada de volta da conexão. Windows 95 ou os 98 PC indicam “uma mensagem da rechamada de espera” para indicar que uma rechamada é em andamento.

Configuração de cliente Windows NT e 2000

Configurar estas Plataformas para pedir a rechamada. Termine estas etapas para configurar-las:

  1. Escolha o iniciar > programas > acessórios > as comunicações > a rede e as conexões dial-up.

  2. Escolha avançado > preferências de discagem do menu.

  3. Clique a aba da rechamada para alcançar o menu dos recursos de chamada de volta segundo as indicações de figura 1.

  4. Configurar suas opções de chamada de volta como necessárias:

    • A fim de não usar a função de rechamada, clique no botão No Callback (Sem Rechamada).

    • Para ser informado sobre o que fazer quando um servidor oferece o retorno de chamada, clique no botão Ask Me During Dialing When The Server Offers.

    • Para aceitar automaticamente ofertas da rechamada, clique sempre a chamada mim para trás no botão abaixo dos números, e selecione o dispositivo para usar-se da lista.

    • Para mudar o número de telefone da rechamada, selecione o dispositivo e clique o botão Edit. Incorpore o número ao campo de número de telefone segundo as indicações de figura 1, e clique então a APROVAÇÃO no atendimento mim para trás na caixa de diálogo.

  5. Clique o campo de número de telefone, e incorpore o número ao atendimento mim para trás na caixa de diálogo (mostrada em figura 1). Clique a APROVAÇÃO quando você é terminado.

Verificar

Esta seção fornece informações que você pode usar para confirmar se sua configuração está funcionando adequadamente.

A Output Interpreter Tool (somente clientes registrados) oferece suporte a determinados comandos show, o que permite exibir uma análise da saída do comando show.

  • mostre o active isdn — informação dos indicadores sobre o recebimento atual e chamadas ISDN que parte. Use este comando verificar se a rechamada esteve terminada com sucesso. Se a rechamada é bem sucedida, mostre que active isdn mostra o atendimento como que parte no servidor de chamada de volta.

  • usuários da mostra — informação dos indicadores sobre as linhas ativa no roteador. Você pode igualmente usar o comando show caller se sua versão de Cisco IOS Software a apoia.

  • discador da mostra — informação geral de diagnóstico das mostras para as relações configuradas para o Dial-on-Demand Routing (DDR).

Troubleshooting

Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.

Comandos para Troubleshooting

Nota: Antes de emitir comandos debug, consulte Informações importantes sobre comandos debug.

Para obter mais informações sobre dos comandos debug, veja a referência do comando Debug do Cisco IOS Release 12.0.

  • debugar a autenticação aaa — informação dos indicadores na autenticação de AAA.

  • debug aaa authorization — informação dos indicadores na autorização de AAA.

  • debug callback — eventos de chamada de volta dos indicadores quando o roteador usar um modem e um a chat script ao retorno de chamada em uma linha terminal.

  • debugar o modem — permite-o de observar a atividade de linha de modem em um servidor de acesso.

  • debugar ppp [pacote | negociação | erro | autenticação] — a informação dos indicadores no tráfego e nas trocas em uma rede interna essa executa o PPP.

    • pacote — pacotes PPP dos indicadores que estão sendo enviados e recebidos. (Este comando mostra cópias parciais da memória de pacote de nível baixo.)

    • negociação — pacotes PPP dos indicadores transmitidos durante a inicialização de PPP, quando as opções de PPP forem negociadas.

    • os erros de protocolo e as estatísticas de erros das exibições de erros associaram com a negociação e a operação da conexão PPP.

    • autenticação — mensagens do protocolo de autenticação dos indicadores, que incluem trocas da RACHADURA e PAP.

  • debugar o bate-papo — mostra o aperto de mão que ocorre entre o servidor de acesso e seu modem interno quando o modem for instruído discar para fora. Um bate-papo-script é um grupo de esperar-envia os pares da corda que definem o aperto de mão entre o equipamento de terminal de dados (DTE) e os dispositivos da data communications equipment (DCE).

  • debugar o q931 de ISDN — indica as mensagens de configuração de chamada e desconexão ISDN Q.931 (canal D) e debugar-las. Nesta encenação, a chamada de modem é levada como um serviço de portador de voz sobre a rede telefônica pública comutada (PSTN).

  • debug modem csm — permite-o de pesquisar defeitos problemas do módulo de switching de chamadas (CS) no Roteadores com modens digitais internos. Com este comando, você pode rastrear a seqüência completa de chamadas recebidas e enviadas por switching.
