Switch1(config)interface FastEther 0/11 ? Switch1(configif)shutdown ? Switch1(configif)switchport mode dynamic desirable ? Switch1(configif)no shutdown ? 將 Switch2的 FastEther 0/11接口的 Trunk配置為 auto模式： ? Switch2(config)interface FastEther 0/11 ? Switch2(configif)shutdown ? Switch2(configif)switchport mode dynamic auto ? Switch2(configif)no shutdown 實驗結(jié)果 ? 在 Switch1上用 show interfaces FastEther 0/11 switchport查看端口信息 ? Name: Fa0/11 ? Switchport: Enabled ? Administrative Mode: dynamic desirable ?
