Call up the command with the following parameters:
no {up|down}[{<interface-type><interface-id>}]
The parameters have the following meaning:
The message when establishing a connection is
-
The message when a connection is down is disa-
bled
-
Type or speed of the interface Enter a valid interface.
Module no. and port no. of the interface
For information on names of addresses and interfaces, refer to the section "Interface
identifiers and addresses (Page 39)".
If you do not select an interface, the function is disabled for all available interfaces.
The settings for monitoring the physical network connections have been configured.
You can display the current setting with the show events faults config command.
You enable the function with the
link command.
With Fiber Monitoring, you can monitor the received power and the loss of power on optical
links between two switches.
If you enable fiber monitoring on an optical port, the device sends the current transmit power
of the port to its connection partner using LLDP packets. In addition to sending, the device
also checks whether corresponding information is received from the connection partner.
Regardless of whether the IE switch receives diagnostics information from its connection
partner, it monitors the received power measured at the optical port for the set limit values.
If fiber monitoring is enabled on the connection partner, the connection partner transfers the
current value for the transmit power of the port to the device. The device compares the value
it has received for the transmit power with the actually received power. The difference
between the received power and the transmit power represents the power loss on the link.
The calculated power loss is also monitored for the set limit values.
If the value of the received power or the power loss falls below or exceeds the set limit
values, an event is triggered. You can set limit values in two stages for messages with the
severity levels "Warning" and "Critical".
