when monitored traffic
exceeds the upper
threshold.
(Optional.) Enable the
6.
Ethernet interface to output
log messages when it
detects storm control
threshold events.
(Optional.) Enable the
7.
Ethernet interface to send
storm control threshold
event traps.

Forcibly bringing up a fiber port

IMPORTANT:
Copper ports do not support this feature.
As shown in
physical state of the fiber port is up only when both transmit and receive fibers are physically
connected. If one of the fibers is disconnected, the fiber port does not work.
To enable a fiber port to forward traffic over a single link, you can use the port up-mode command.
This command forcibly brings up a fiber port, even when no fiber links or transceiver modules are
present for the fiber port. When one fiber link is present and up, the fiber port can forward packets
over the link unidirectionally.

Remarks
By default, storm control is
disabled.
By default, the Ethernet interface
outputs log messages when
monitored traffic exceeds the
upper threshold or drops below
the lower threshold.
By default, the Ethernet interface
sends traps when monitored
traffic exceeds the upper
threshold or drops below the
lower threshold from the upper
threshold.
