 # ARP Table
+
+The **ARP table** shows you the IP address and MAC address of all devices on your network with which the computer has already established a connection.
+
+:::info
+
+ARP (Address Resolution Protocol) is a layer 2 protocol for mapping IP addresses to MAC addresses. The ARP table is a list of all IP addresses and the corresponding MAC addresses of the devices on the network. When a device needs to send data to a specific IP address, it first checks its ARP table to see if it already has the MAC address for that IP address. If the MAC address is not found in the ARP table, the device will send a broadcast message called an ARP request to the network asking which device owns that IP address. The device that owns the IP address will then respond with its MAC address, and the requesting device will update its ARP table with the new mapping. ARP cache poisoning attacks can manipulate the contents of the ARP table, leading to security issues.

+In addition, further actions can be performed using the buttons at the bottom left:
+
+- **Add entry...** - Opens a dialog to add an entry to the ARP table.
+- **Delete entry** - Delete the currently selected entry from the ARP table.
+- **Delete table** - Delete all entries from the ARP table.

 # Bit Calculator
+
+With the **Bit Calculator** different data units can be converted. Based on the input number and the selected unit the different units like bits, bytes, kilobits, kilobytes, megabits, megabytes, etc. are calculated.

 # Connections
+
+In **Connections** you can see all connections with source and destination IP endpoint (IP address and port) and with the associated process that are currently running on your computer.

 # Discovery Protocol
+
+In **Discovery Protocol** you can capture for LLDP (Link Layer Discovery Protocol) and/or CDP (Cisco Discovery Protocol) frames to see to which switch or router your device is connected. The information such as device name, port, VLAN, etc. are displayed in a table.
+
+:::info
+
+The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Layer 2 network protocol used by network devices, especially switches, to advertise their identity, capabilities, and neighbors on an IEEE 802 Local Area Network (LAN). If configured, LLDP messages are sent out periodically as frames with the destination MAC address of `01:80:c2:00:00:0e`. The default time interval is 30 seconds.
+
+The Cisco Discovery Protocol (CDP) is a proprietary Layer 2 protocol used by Cisco Systems to exchange information about network devices. If configured, CDP messages are sent out periodically as frames with the destination MAC address `01:00:0c:cc:cc`. The default time interval is 60 seconds.
+
+:::
+
+:::warning
+
+If you are using a hypervisor like Hyper-V with a virtual switch configured as "External network" which is shared with host where NETworkManager is running, you may not receive any packets. This is because the virtual switch does not forward the LLDP or CDP frames to the host. You may temporarily change the virtual switch to "Internal network" or "Private network", if you want to use the Discovery Protocol to see which switch or router your device is connected to. You can also verify this behavior by using Wireshark.
