Ethernet Ports Overview
This chapter describes the Ethernet software CLI commands used for configuring and monitoring your
switch's Ethernet port parameters. These commands allow you to handle administrative or port-related
requests to and from SNMP, the CLI, or WebView.

OmniSwitch 6800 Series Combo Ports

All OmniSwitch 6800 Series switches have four ports that are shared between four copper 10/100/1000
RJ-45 connections and four fiber 1 Gbps SFP slots, which can accept any qualified 1 Gbps SFP transceiv-
ers. These ports are known as combo ports (also sometimes referred to as "hybrid" ports).
You can use either the copper 10/100/1000 port or the equivalent fiber SFP port but not both at the same
time. By default, combo ports are set to preferred fiber, which means that the OmniSwitch 6800 Series
switch will use the fiber SFP port instead of the equivalent copper RJ-45 port if both ports are enabled and
have a valid link. However, if the SFP port goes down the equivalent RJ-45 port will come up. This mode
can be used if you want use the fiber connection as your main link while having a copper link as a backup.
For example, on the OmniSwitch 6800-48 ports 45–48 are combo ports. If cables are connected into the
copper port 45 and the fiber port 45 the fiber SFP link will be the active one. If the SFP link goes down
then the copper port will automatically become active. No user intervention is required.
Note. See "Valid Port Settings" on page 1-5
information on combo ports on OmniSwitch 6800 Series chassis.
The following three additional optional combo port modes are user configurable:
Preferred copper. In this mode, the OmniSwitch 6800 Series switch will use the copper RJ-45 port
•
instead of the equivalent fiber SFP port if both ports are enabled and have a valid link.
Forced fiber. In this mode, the OmniSwitch 6800 Series switch will always use the fiber SFP port
•
instead of the equivalent copper RJ-45 port.
Forced copper. In this mode, the OmniSwitch 6800 Series switch will always use the copper RJ-45
•
port instead of the equivalent fiber SFP port.
