PLANET WGSW-50040 - Manual (Page 93)

1. Combo port is a conception involving the physical layer and the LLC sublayer of the
datalink layer. The status of a combo port will not affect any operation in the MAC
sublayer of the datalink layer and upper layers. If the bandwidth limit for a combo port
is 1Mbps, then this 1Mbps applies to the active port of this combo port, regardless of
the port type being copper or fiber.
2. If a combo port connects to another combo port, it is recommended for both parties to
use copper-forced or fiber-forced mode.
Run show interface under Admin Mode to check for the active port of a combo port .The
following result indicates if the active port for a combo port is the fiber cable port:
Hardware is Gigabit-combo, active is fiber.
Example:
Setting ports 1/21-24 to fiber-forced.
Switch(config)#interface ethernet 1/21-24
Switch(Config-Port-Range)#combo-forced-mode sfp-forced
