Feature OverviewThe ASR 901 router supports DOM as per the standard SFF-8724 Multi-Source Agreement (MSA). Thisfeature allows monitoring real-time parameters of the router, such as optical input and output power,temperature, laser bias current, and transceiver supply voltage. These parameters are monitored against thethreshold values. The real-time DOM parameters can be monitored using command line interface or SNMPinterface. Effective with Cisco IOS Release 15.3(3)S, Cisco ASR 901 supports DOM for both 1G and 10GSFPs.

DOM allows the user to view the threshold violation messages. To display the threshold violation messages,you must enable transceiver monitoring. For information on enabling transceiver monitoring, see How toEnable Transceiver Monitoring, on page 2.

The command line output for the real-time parameters is shown using the show interfaces transceivercommand. To enable threshold notification in the transceiver via SNMP, use the snmp-server enable traps

transceiver command. You can use the show controllers gig 0/x command to check whether SFP’s are DOMcapable. This command displays the SFP details.

How to Enable Transceiver MonitoringComplete the following steps to enable transceiver monitoring:

Restrictions

• You need the transceiver module compatibility information for configuring transceiver monitoring. Thecompatibility matrix that lists the support for DOM in the Cisco transceiver modules is available at thefollowingURL: http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_8031.html

• In case of combo ports with SFP and RJ45 provision, when SFP is inserted in slot or port and media typeis not configured to SFP, DOM is functional only if global transceiver monitoring is enabled.

• CISCO-ENTITY-SENSOR-MIB traps are sent only once after the threshold violation. However, SYSLOGtraps are sent according to the monitoring interval.
