4.3 Configuring Interface
The Layer 2 switches only see the MAC address in an incoming packet to determine
where the packet needs to come from/to and which ports should receive the packet. The
Layer 2 switches do not need IP addresses to transmit packets. However, if you want to
access to the switch from a remote place with TCP/IP through SNMP or telnet, it requires
an IP address.
You can enable the interface to communicate with another network device on the network
by assigning an IP address as follows:

face is not enabled, you cannot access it from a remote place, even though an IP address
has been assigned.
To configure an interface, you need to open Interface Configuration mode first. To open
