Ethernet interface naming conventions

The GE and 10-GE interfaces on the S5500-SI&S5500-EI series Ethernet switches are named in the
format of interface-type A/B/C, where the following definitions apply:
• If the switch does not support Intelligent Resilient Framework (IRF), A takes 1. If the switch support IRF,
A represents the ID of the switch in an IRF virtual device. If the switch is not assigned to any IRF
virtual device, A takes 1.
B represents a slot number on the switch. It takes 0 for fixed interfaces, 1 for interfaces on interface
•
expansion card 1, and 2 for interfaces on interface expansion card 2.
C represents the number of an interface on a slot.
•
NOTE:
For more information about the expansion cards, see the
•
Installation Guide
• The GE ports of the GE interface expansion card are displayed as 10-GE ports on the switch where the
expansion card is installed.

Configuring a Combo interface

Introduction to Combo interfaces
A Combo interface is a logical interface that comprises one optical (fiber) port and one electrical
(copper) port. The two ports share one forwarding interface and cannot work simultaneously. When you
enable the electrical port, the optical port is disabled automatically and vice versa.
The optical and electrical ports of a Combo interface are Layer 2 Ethernet interfaces and have their own
separate interface views, in which you can activate the optical or electrical port, and configure other port
attributes such as the interface rate and duplex mode.
Configuration prerequisites
Before you configure a Combo interface, complete the following tasks:
• Use the display port combo command to find out the Combo interfaces on your device and identify
the two physical interfaces that comprise each Combo interface.
