Interfaces on Cisco [device type] are NOT administratively down by default.

In networking, the behavior of interfaces on different types of devices can vary significantly based on their intended function. Switch interfaces are generally not administratively down by default because they are designed to facilitate connectivity right out of the box. When power is applied to a switch, its ports are typically in an "up" state unless specifically configured otherwise. This allows devices to connect and communicate immediately, promoting quick network setup and troubleshooting.

In contrast, routers and other devices like firewalls often have interfaces that are administratively down until configured for use since routers usually require specific configurations to handle routing and network traffic effectively. Access points are often similarly configured to remain inactive until proper settings are applied for wireless connectivity.

The behavior of a switch ensures that as soon as it is powered on, it can begin to function in its role of creating and managing network segments, enhancing network availability and reducing delays typically associated with configuration. This characteristic makes switches unique in their operational readiness compared to routers, firewalls, and access points.
