How to find out other devices mac address using terminal emulator

The default gateway is usually the address of the interface on the router connected to the local network. It is often used to connect a local network to the Internet. The default gateway is the destination that routes traffic from the local network to devices on remote networks.

When a host sends a packet to a device on a different IP network, then the packet is forwarded to the default gateway, because a host device cannot communicate directly with devices outside of the local network. When a host sends a packet to a device that is on the same IP network, the packet is simply forwarded out of the host interface to the destination device.

Default gateway: Identifies the router to send a packet to when the destination is not on the same local network subnet.

Subnet mask: Identifies with which network subnet the host can communicate.

IP address: Identifies a unique host on a local network.

To enable network access, devices must be configured with IP address information to identify the appropriate: In the Branch and Central LANs, hosts are connected either directly or indirectly (via WAPs) to the network infrastructure using a Layer 2 switch.

The corporate website server is connected using an Ethernet cable to the edge router interface.

Layer 3 multilayer switches connect to an Ethernet interface on the edge router using Ethernet cables.

Layer 2 switches connect redundantly to multilayer Layer 3 switches using Ethernet fiber-optic cables (orange connections).

Desktop PCs and VoIP phones connect to Layer 2 switches using Ethernet cables.

The Central site devices connect as follows:

The edge router also connects to an ISP for backup purposes.

The edge router connects to a WAN service provider (SP).

An edge router is a device that sits at the edge or boundary of a network and routes between that network and another, such as between a LAN and a WAN.

Layer 2 switches connect to an Ethernet interface on the edge router using Ethernet cables.

The WAPs connect to switches using Ethernet cables.

Laptops and smartphones connect wirelessly to wireless access points (WAPs).

Desktop PCs and voice over IP (VoIP) phones connect to Layer 2 switches using Ethernet cables.

Corporate resources (i.e., file servers and printers) connect to Layer 2 switches using Ethernet cables.

The Branch site devices connect as follows:

The cable modem connects to the Internet service provider (ISP) network.

The home router connects to the service provider cable modem using an Ethernet cable.

A network printer connects using an Ethernet cable to the switch port on the home router.

Laptops and tablets connect wirelessly to a home router.

Home Office devices can connect as follows: Figure 1-6 Sample LAN and WAN Connections
