General Ethernet Interface Configuration
GE and 10GE ports on the S5120-EI series Ethernet switches are numbered in the following format:
interface type A/B/C.
z A: Number of a member device in an IRF stack. If no IRF stack is formed, this value is 1.
z B: Slot number on the device. A value of 0 represents the slot where the fixed ports of the device
are located; a value of 1 represents the slot where the ports of interface expansion card 1 are
located; a value of 2 represents the slot where the ports of interface expansion card 2 are located.
z C: Number of a port on a slot.

Combo Port Configuration
Introduction to Combo port
A Combo port can operate as either an optical port or an electrical port. Inside the device there is only
one forwarding interface. For a Combo port, the electrical port and the corresponding optical port are
TX-SFP multiplexed. You can specify a Combo port to operate as an electrical port or an optical port.
That is, a Combo port cannot operate as both an electrical port and an optical port simultaneously.
When one is enabled, the other is automatically disabled.
