Port LEDs and Modes

Cisco Catalyst 9500 Series Switches
Each Ethernet port, 1-Gigabit Ethernet module slot, and 10-Gigabit Ethernet module slot has a port LED.
These port LEDs, as a group or individually, display information about the switch and about the individual
ports. The port mode determines the type of information shown by the port LEDs.
To select or change a mode, press the Mode button until the desired mode is highlighted. When you change
port modes, the meanings of the port LED colors also change.
When you press the Mode button on any switch in the switch stack, all the stack switches change to show the
same selected mode. For example, if you press the Mode button on the active switch to show the SPEED
LED, all the other switches in the stack also show the SPEED LED.
