Port Mode LEDs
The Cisco StackWise EtherSwitch service module has a Mode button that allows you to toggle through
the port LED modes. (See
Figure 18-6
.) The port modes determine the type of information displayed
through the port LEDs. For more information about port LEDs, see the
“Port LEDs” section on
page 18-11
.
To choose 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 18-6
lists the modes and their meanings.
