Hi Lemine,
The management Vlan is a default one on swithes so, if you want to ping
your switch, your pc should be configured using an IP of the management
Vlan IP range. But when you create a Vlan on a switch, it means you have
two Vlan. The default one and the last one you created. In that case, you
can not manage or ping your switch being in the second Vlan.
