O recurso Bisync Serial Tunnel (BSTUN) permite suporte para dispositivos que usam o protocolo de enlace de dados Bisync. Esse protocolo permite que as empresas transportem o tráfego da Bisync pela mesma rede que suporta sua Arquitetura de Rede de Sistemas (SNA - Systems Network Architecture) e tráfego multiprotocolo, o que elimina a necessidade de instalações separadas da Bisync. Com o Frame Relay, você pode usar o recurso de confirmação local para fornecer o encerramento local da sessão no peer BSTUN.
Neste exemplo, um BSTUN ponto-a-ponto é configurado com reconhecimento local sobre Frame Relay. Os estados relevantes na saída do comando show bstun foram destacados neste documento.
Observação: embora os comandos debug bstun packet/event e debug bsc packet/event não causem utilização excessiva da CPU, o comando logging buffered é usado para copiar a saída para o arquivo de log.
