What is the default configuration for port speed unless a failure occurs?

  1. Static speed configuration

  2. Auto speed configuration

  3. Manual speed configuration

  4. Speed set to zero

The correct answer is: Auto speed configuration

The default configuration for port speed is auto speed configuration. In networking equipment such as Cisco switches and routers, when no specific configuration is applied to determine the port speed, devices typically operate in an auto-negotiation mode. This means they automatically detect the speed and duplex settings of the device connected to their port. The auto speed configuration allows for flexibility and adaptability in the network, ensuring that the devices can communicate effectively regardless of the specific configurations set on either end. This capability is particularly important in environments where devices might vary in their port speed capabilities, leading to optimized performance without requiring manual configuration. In scenarios where a failure occurs or a mismatch in speed settings is detected, this auto-negotiation can fail, prompting engineers to implement static or manual configurations as needed. However, under normal operational conditions, the default remains the auto speed configuration, ensuring a seamless connection with other network devices.
