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.

Switch 4210 52-Port does not support Combo port, but it provides two 10/100/1000Base-T
auto-sensing Ethernet ports and two 100/1000Base-X SFP ports on the front panel.
