PCping不通直连的交换机

tuhaogold

拓扑如图，交换机1配置如下:

Switch>en

Switch#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#hostname SW1

SW1(config)#int f0/2

SW1(config-if)#switchport mode access

SW1(config-if)#switchport access vlan 2

SW1(config-if)#int f0/4

SW1(config-if)#switchport mode access

SW1(config-if)#switchport access vlan 3

SW1(config-if)#int f0/8

SW1(config-if)#switchport mode trunk

SW1(config-if)#^Z

SW1#

%SYS-5-CONFIG_I: Configured from console by console

SW1#wr

Building configuration...

[OK]

用交换机pingPC怎么ping不通呢？

哪个交换机啊，要是用接入层交换机ping，IP都没有，当然不通

你能把两个交换机的配置都贴这吗？

划了啊···我这个实验是按照一个实验手册做的

生气，居然不能截图白做了
你看看有没有开启三层交换机路由功能 ip routing

zxq123

仔细看了一下你好像真的没开启，在三层交换机那里加一句ip routing就行了

开启了仍然ping不通、、、、、你做通的 话可以把PTK发我一下不？多谢了1060628684@qq.com

你PC机器设置有没有问题呢？

btlass

二层配置上的VLAN创建呢？模拟器有问题吧
