Feature Overview
The ASR 901 router supports DOM as per the standard SFF-8724 Multi-Source Agreement (MSA). This
feature 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
the threshold values. The real-time DOM parameters can be monitored using command line interface or
SNMP interface. Effective with Cisco IOS Release 15.3(3)S, Cisco ASR 901 supports DOM for both 1G
and 10G SFPs.
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 to Enable Transceiver Monitoring” section on page 40-2.
