Fiber Monitoring Protocol

Requirements
● To be able to use the Fiber Monitoring Protocol (FMP), enable LLDP. The FMP
information is appended to the LLDP packets.
● You can only use the Fiber Monitoring Protocol (FMP) with transceivers capable of
diagnostics. Devices and modules with transceivers capable of diagnostics have the
supplement "FM" in the name.
Monitoring optical links
With FMP, you can monitor optical links.
If you enable FMP on an optical port, diagnostics information is sent via the port. In addition
to sending, there is also a check to establish whether information is being received.
Regardless of whether the IE switch receives diagnostics information, it monitors the
received power and compares it with selectable power limits.
If you connect two IE switches via optical ports with FMP enabled, they exchange their
diagnostics information. This also allows a power loss to be calculated. The power loss is
also compared with selectable power limits.
If the value of the received power or the power loss falls below a specified limit, an event is
triggered. In "Agent > Event Configuration", you can specify how the IE switch indicates the
event. In "X-300 > Fault Mask", you can also specify whether or not an error should be
signaled.
