Destination host unreachable solution

[kw247a]

Hi, I'm a student looking for a solution for my 'destination host unreachable' when I try to ping between PC-A PC-B. My prior pings works besides this one and I have no idea what I messed up on. Any input is appreciated.

I attached the files below.

Hi

I see in S2 that there is one trunk port, I assume this port is connected to S1. You also have one port associated with vlan 30. Most switches will create the Layer2 vlan when you configure "switchport access vlan x" So to verify in S2 that the vlan exist, do "show vlan" and see that the vlan 30 is present.

In S1, there is 2 trunk ports, I assume one is to connect to the router and the other is to connect to S2. I also see one port configured for vlan 20. Here is where the possible mistake is. Because there are no port in S1 assigned to vlan 30, so vlan 30 is not autoconfigured. The fact that you allowed the vlan 30 on the trunk will not create the vlan. You can check this with "show vlan".

To make this work you have to create the vlan 30 in S1, in config mode, use the command "vlan 30" then type "exit"
