Network interfaces
This section describes the port types in the Brocade NetIron CES, Brocade NetIron CER 2000
series devices.
10/100/1000 Mbps ports
The 10/100/1000 ports on the device use auto-sensing and auto-negotiating to determine the
speed (10 Mbps, 100 Mbps, or 1000 Mbps) and duplex mode (full-duplex or half-duplex) of the port
at the other end of the link and adjust port speed accordingly.
Combination ports
On devices with combination (combo) ports, one port out of each pair of copper and fiber ports can
be active at a time. Combo ports are numbered 1-4. For example, you can use either copper port 2
or fiber port 2, but not both at the same time. You can use a combination of fiber and copper ports
or all copper or all fiber ports, as needed.
If you attach both the copper and fiber connectors for a port to the network, the fiber connectors
take precedence over the copper connectors. These ports support true media automatic detection,
meaning the device selects the fiber or copper connector based on link availability. If a fiber link
cannot be established, the device selects the copper media.
