# Network Interfaces

## Interface Overview

After logging in to the router, click "Network > Interfaces" to view and manage the network interfaces, as shown below. 

The background colors of the first column do not indicate their connection status; instead, they identify their firewall zones. The second column provides brief information and the connection status of each interface.

### Explanation of Terms

**Protocol** – The communication rules and methods used for data transmission.

**Uptime** – The duration of the network interface's continuous operation since the last connection. H is hours, M is minutes, and S is seconds.

**MAC** – Short for Media Access Control, a unique hardware identification number assigned to each network interface, displayed as six pairs of hexadecimal digits.

**RX** – Received (download) packets. **TX** – Transmit (upload) packets. They indicate the real-time data stream instead of the internet speed.

**IPv4** – Short for Internet Protocol version 4
