Network endpoints refer to the devices or nodes that are connected to a network and are responsible for sending and receiving data. Endpoints can be physical devices, such as desktop computers, laptops, servers, printers, and mobile devices, or they can be virtual entities such as virtual machines or software applications.

Endpoints are essential components of any network infrastructure, as they are the points of entry and exit for data flowing into and out of the network. They facilitate communication between devices by exchanging packets of information across the network, and they also play a crucial role in enforcing security policies and access controls.

Endpoints can support inter-VLAN connectivity, meaning that they allow devices that belong to different VLANs to communicate with each other. However, supporting inter-VLAN connectivity is not the primary function of endpoints.

Endpoints can also pose a threat to the network if they are compromised by attackers. Malicious actors can use compromised endpoints to launch attacks against other devices on the network or to steal sensitive data. Therefore, it is critical to secure endpoints by implementing strong access controls, authentication mechanisms, and endpoint protection software.

Endpoints do not act as routers to connect a user to the service provider network. Routers are devices that forward data packets between different networks, and they play a critical role in connecting a user's network to the service provider's network.

Finally, while endpoints can enforce policies for campus-wide traffic going to the Internet, this is not their primary function. Endpoint security policies typically focus on protecting the device itself from threats such as malware or unauthorized access, rather than controlling traffic flow across the network.
