Assigning IP Address
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 V8102 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.

has been assigned.

Interface Configuration
mode first. To open
