Port

This section describes numbering rules, positions, quantity, and other information about the ports of
the switch module.

Port numbering rules

Ports of the switch module are numbered in three dimensions: A, B, and C.
•
A: Indicates the number of the IRF member device. Since the switch module does not have any
IRF by default, the default value of A is 1.
•
B: Indicates an internal or external port. 0 indicates an internal port, and 1 indicates an external
port.
•
C: Indicates the sequence number of the port.
