Detailed explanation-1: -Encapsulation-The network layer receives a protocol data unit (PDU) from the transport layer. In a process called encapsulation, the network layer adds IP header information, such as the IP address of the source (sending) and destination (receiving) hosts.
Detailed explanation-2: -For example, the term Layer 3 PDU refers to the data encapsulated at the Network layer of the OSI model.
Detailed explanation-3: -A protocol data unit is information delivered as a unit among peer entities of networks containing control information, address information or data. In layered systems, PDU represents a unit of data specified in the protocol of a given layer, which consists of protocol control information and user data.
Detailed explanation-4: -If the PDU is connected to an Ethernet network with a DHCP server, an IP address is automatically assigned. The default name for the PDU is PDU. You can also disable DHCP and enter a static IP address. To access the PDU with its default network setting, ensure that static IP addresses are allowed in your network.
