the port. For example, a bandwidth limit of 101 M (or more) cannot be set for a 10/100M Ethernet
port. But for a 10/100/1000M port working under 100M, a bandwidth limit of 101M (or more) is
permitted.
Example: setting the bandwidth limit of ports 1 – 8 of slot 3’s card to 40M.

Command: combo-forced-mode {copper-forced | copper-preferred-auto | sfp-forced |
sfp-preferred-auto }
no combo-forced-mode
Function: Sets to combo port mode (combo ports only); the “no combo-forced-mode” command
restores to default combo mode for combo ports, i.e., fiber ports first.
Parameters: copper-forced forces use of copper cable ports; copper-preferred-auto for copper
cable port first; sfp-forced for fiber cable forces to use fiber cable port; sfp-preferred-auto for fiber
cable port first.
Command mode: Interface Mode
Default: The default setting for combo mode of combo ports is fiber cable port first.
Usage Guide: The combo mode of combo ports and the port connection condition determines the
active port of the combo ports. A combo port consist of one fiber port and a copper cable port. It
should be noted that the speed-duplex command applies to the copper cable port while the
negotiation command applies to the fiber cable port, they should not conflict. For combo ports, only
one, a fiber cable port or a copper cable port, can be active at a time, and only this port can send and
receive data normally.
For the determination of the active port in a combo port, see the table below. The headline row in
the table indicates the combo mode of the combo port, while the first column indicates the
connection conditions of the combo port, in which “connected” refers to a good connection of fiber
cable port or copper cable port to the other devices.
