交换机是3550smi-48,iso版本是12.1(22)EA1a,配置了三个vlan,分别是:vlan2(192.168.2.1 255.255.255.0)、vlan3(192.168.3.1 255.255.255.0)、vlan4(192.168.4.1 255.255.255.0)\r\n\r\n防火墙:inside(10.0.0.2)、outside(192.168.181.20)\r\n\r\n交换机端口0/47连接防火墙的inside(ethernet1)\r\n\r\n交换机的配置过程:\r\nip routing\r\n\r\nvlan 2\r\nvlan 3\r\nvlan 4\r\ninterface vlan 2\r\nip address 192.168.2.1 255.255.255.0\r\nno shutdown\r\nvlan3和vlan4同样\r\n\r\ninterface fastethernet 0/47\r\nno switchport\r\nip address 10.0.0.1\r\nno shutdown \r\n\r\nip route 0.0.0.0 0.0.0.0 10.0.0.2\r\n\r\n问题是从vlan2、vlan3、vlan4内的任何节点ping 10.0.0.2都不通,ping 10.0.0.1可通,请大家帮我分析一下是什么原因! |
