Port Trunk Configuration
3-41
Use the Port Trunking Configuration screen to set up port trunks as shown below:
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).
Parameter Description
Trunk A unique identifier for this trunk. You can configure up to five trunks per switch.
Status Enables or disables the displayed trunk.
Member List You can create up to 12 trunks for the entire stack by specifying the trunk
