NOTE
By default, a combo port works in auto mode, in which the port type is determined as follows:
l If the optical port has no optical module installed and the electrical port has no network cable
connected, the port type depends on which port is connected first. If the electrical port is connected
by a network cable first, the electrical port is used for data switching. If the optical port has an optical
module installed first, the optical port is used for data switching.
l
If the electrical port has a network cable connected and is in Up state, the electrical port is still used
for data switching when the optical port has an optical module installed.
l
If the optical port, no matter in Up or Down state, has an optical module installed, the optical port is
still used for data switching when the electrical port has a network cable connected.
l
If the optical port has an optical module installed and the electrical port has a network cable connected,
the optical port is used for data switching after the switch restarts.
You can configure a combo port as an electrical or optical port using the combo-port command.
