Can you be able to ping the management IP of a Vlan that is set as native vlan????

Hi Guys,

Playing around packet tracer building labs I have noticed that when I create a management IP address for a native VLAN, I cant ping it from a directly connected host (even though the host is connected to to a port assigned to the native vlan).

Is there a reason this isnt able to happen or have I made a mistake during the config, when I do however create a management IP for a non Native Vlan I am able to ping away.

Any info would be helpful.

Thanks
Pujan

Put your PT file up. How about some show commands to troubleshoot. It most likely misconfigured.

Shouldn't be any reason it can't ping if configured correctly. Or some weird PT bug of which there are a million.

Ya I am going to chalk this up as a mis-configuration or strange PT. Put your config up so we can see and advise.

Hi guys

Any particular reason you have host ports configured as trunk instead of access?

Hi swamprat,

After I wasnt able to ping the IP of the switch I thought as I have configured it under the native VLAN that I might get it to work if i put the switchport in the same native VLAN, which still didnt fix it

You can't put the same network on both L3 interfaces.

You have to put a link to Dropbox or Gdrive.

Yes you have an overlapping network for both SVIs. Put them into separate subnets.
