Try to re-enter the privileged mode denoted by symbol. You should see a dialog with username and password request. After confirming that the device is accessible via TelnetI highly recommend setting up secure access via SSH. See the instruction in this article.

For example, switch has 24 FastEthernet ports and 2 Gigabit Ethernet ports. For users connection only Fast Ethernet will be used. It would be great to add description strings for each interface. Then, ports will be shown next to each Vlan.

By previous commands we shared one physical switch to 4 logical ones Vlan 1, Vlan 10, Vlan 20 and Vlan Connections between hosts will be able only if their ports on the switch belongs to the same Vlan.

You need a router connected to the switch using a trunk port in order to that all networks could communicate with each other. All necessary information about configuration can be found in this article. The difference of trunk interface is that the transmission of each packet of traffic is marked by Vlan number.

This allows the device to forward packets correctly. After making all of the steps, connect two workstations to ports belonging to the same Vlaneg with the numberset ip addresses A successful response means that everything works as it should.
