Port Numbering
Overview
Before you configure your system, read this chapter to become familiar
with the physical port numbering scheme on the system. Understanding
the port numbering scheme enables you to:
■
Manage your bridge ports, especially if you use trunking, as described
in Chapter 8.
■
Accurately define your virtual LANs (VLANs), as described in
Chapter 9.
Numbering Rules Your system supports up to 24 ports, numbered consecutively:
■
Port 1 represents the first port associated with a module in Slot 1 (the
top left slot on the system) and continues for the rest of the ports
associated with Slot 1.
■
Numbering continues for the ports associated with a module in Slot 2
(top right).
■
Numbering continues for the ports associated with a module in Slot 3
(bottom left).
■
Numbering continues for the ports associated with a module in Slot 4
(bottom right).
