Port LEDs and Modes

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. Table 1-5lists the mode LEDs and their associated port modes and meanings.

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. Table 1-6explains how to interpret the port LED colors in different port modes.

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.

Alternating

 

Link fault. Error frames can affect connectivity, and errors such as

 

 

 

green-amber

 

excessive collisions, CRC errors, and alignment and jabber errors

 

 

 

 

 

are monitored for a link-fault indication.

 

 

 

 

 

 

 

 

 

 

Amber

 

Port is blocked by Spanning Tree Protocol (STP) and is not

 

 

 

 

 

forwarding data.

 

 

 

 

 

After a port is reconfigured, the port LED can be amber for up to 30

 

 

 

 

 

seconds as STP checks the switch for possible loops.
