Digital Optical Monitoring

This feature module provides information on the digital optical monitoring (DOM) feature for the Cisco ASR 901 Series Aggregation Services Router.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn . An account on Cisco.com is not required.

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.

The command line output for the real-time parameters is shown using the show interfaces transceiver command. 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 DOM capable. This command displays the SFP details.

How to Enable Transceiver Monitoring

Complete the following steps to enable transceiver monitoring:

Restrictions

You need the transceiver module compatibility information for configuring transceiver monitoring. The compatibility matrix that lists the support for DOM in the Cisco transceiver modules is available at the following URL: 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 type is 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, SYSLOG traps are sent according to the monitoring interval.

Procedure

	Command or Action	Purpose
Step 1	enable Example: `Router> enable`	Enables the privileged EXEC mode. Enter your password if prompted.
Step 2	configure terminal Example: `Router# configure terminal`	Enters the global configuration mode.
Step 3	transceiver type all Example: `Router(config)# transceiver type all`	Enters the transceiver type configuration mode.
Step 4	monitoring Example: `Router(config-xcvr-type)# monitoring`	Enables monitoring of all optical transceivers.
Step 5	monitoring interval ; Example: `Router(config-xcvr-type)# monitoring interval 500`	(Optional) Specifies the time interval for monitoring optical transceivers. Valid range is 300 to 3600 seconds, and the default value is 600 seconds.

Examples

The real-time parameters of the router, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage can be monitored using the show interfaces transceiver command.

This section provides sample output for monitoring the real-time parameters on the Cisco ASR 901 router:
