Configuring the Switch
2-33
The RJ-45 ports used for one side of a trunk must all be on the same internal switch
chip. The port groups permitted include:
The 100BASE-FX fiber ports used for one side of a trunk must all be on the same
module. However, the 1000BASE-SX and 1000BASE-LX ports used for one side of
a trunk may be on any switch in the stack, or both on the same switch if used
standalone.
For example, when using Gigabit ports to form a trunk within a stack, the Gigabit
ports will all be at Port 25. In this case, you could specify a trunk group consisting of:
(Unit1-Port25, Unit2-Port25, Unit3-Port25, Unit4-Port25),
or two trunks consisting of:
(Unit1-Port25, Unit2-Port25) and (Unit3-Port25, Unit4-Port25).
