Figure 6-18. The Stacking Module’s Front Panel
Notice the Link and Act LEDs. These LEDs have the same
function as the corresponding LEDs for the switch’s Ethernet
ports. The Link LED lights to confirm a valid link, while the
ACT LED blinks to indicate activity on the link.
The Stack No. seven-segment LED displays the Unit number
assigned to the switch. A 0 (a zero) in the display indicates
that the stacking module is in the process of determining the
stack status and has not yet resolved the switch’s Unit number.
The stacking order can be automatically configured using the
switch’s MAC address − the lower the numerical value of a
given switch’s MAC address, the lower the number in the
stacking order the switch will be assigned. The switch with the
lowest MAC address, will then become the Master Switch.
Alternatively, the stacking order can be manually assigned
using the console’s Command Line Interface (CLI).
You can use the show stacking command to display the
current switch stack information. The syntax of the show
stacking command is as follows:
show stacking {mode/version}
Using the optional parameter mode displays only the stacking
mode of the switches in the switch stack.
Using the optional parameter version displays only the
stacking firmware version of the switches in the switch stack.
