Digital Optical Monitoring
You can configure your Foundry device to monitor XFPs in the system either globally or by specified port. If
monitoring is enabled, console messages, syslog messages, and SNMP traps are sent when XFP operating
conditions warrant and a port is enabled.
To configure all XFP ports for optical monitoring, use the following command:
FastIron Router(config)#optical-monitor
To configure a specific XFP port for optical monitoring, use the following command:
FastIron Router(config)#interface ethernet 1/1
FastIron Router(config-if-e10000-1/1)#optical-monitor
To configure a range of XFP ports for optical monitoring, use the following command:
FastIron Router(config)#interface ethernet 1/1 to 1/2
FastIron Router(config-mif-e10000-1/1-1/2)#optical-monitor
Syntax: [no] optical-monitor <alarm-interval>
The optional <alarm-interval> variable sets the interval in minutes between which alarms or messages are sent.
The default interval is 3 minutes.
You can view the XFP optical monitoring information using the show optic command as shown:
For Temperature, Tx Power, Rx Power, and Tx Bias Current, values are displayed along with one of the following
status values: Low-Alarm, Low-Warn, Normal, High-Warn or High-Alarm. The thresholds that determine these
status values are set by the manufacturer of the XFPs. Table 7.1 describes each of these status values.
Table 7.1: Status Value Description
Status Value Description
Low-Alarm Monitored level has dropped below the "low-alarm" threshold set by the XFP manufacturer.
Low-Warn Monito red level has dropped below the "low-warn" threshold set by the XFP manufacturer.
Normal Monitored level is within the "normal" range" set by the XFP manufacturer.
High-Warn Monitored level has climbed above the "high-warn" threshold set by the XFP manufacturer.
High-Alarm Monitored level has climbed above the "high-alarm" threshold set by the XFP manufacturer.
