Adva FSP 3000 Optical Transport: Optical Interface Status

Distribution: official part of Check_MK
License: GPL
Supported Agents: SNMP

This checks monitors the state and laser parameters of interfaces of the ADVA FSP 3000 scalable optical transport solution.

State information is collected from the SNMP IF-MIB parameters ifAdminStatus and ifOperStatus. Laser information is collected from the FspR7-MIB parameters currentPmSnapshotOutputPower and currentPmSnapshotInputPower.

Lower and upper critical limits can be configured for the input (received) and output (transmit) power of the laser. Per default, not limits are imposed, since meaningful values depend on the type of interface.

A WARN state is triggered if no laser power information can be found. Service interfaces (item name beginning with "S") do not have laser power information, so that non-existent laser power information is ignored for these interfaces.


There are three allowed ways to specify an interface: 1: the last component of the SNMP OID number (as string), the ifDescr of the port or the ifAlias of the port. If you are using the alias, you have to make sure that it is unique by configuring useful aliases in the switch. Check_MK does not check for uniqueness. The default is to use the ifDescr.


The inventory creates one service for each interface that fulfills configurable conditions. Per default these are interfaces which currently are up and are of type 1 (other), 6 (ethernetCsmacd), and 56 (fibreChannel).
