What is the function of the Mode button on the Cisco 2900 LRE XL switch?
A. Catalyst series switches have four LED modes, each of which provides different information about a particular port or about the switch. The Mode button highlights each mode in sequence and is used to select one of the port modes. Changing a port mode changes the information provided by each port status LED. For LED and mode information, see the Product Overview of the Catalyst 2900 Series XL Hardware Installation Guide.
