Enabling DOM

Enable optical monitor and specify the polling and alarm interval.

Enable optical monitoring and specify an alarm interval:

device(config)# optical-monitor 18
Enable optical monitoring and set alarm/warn interval to 18 minute(s)

Enable optical monitoring and allow the alarm interval to be set to the default (on an ICX 7450 device):

device(config)# optical-monitor 
Enable optical monitoring and set alarm/warn interval to default(8 minutes)

Restriction

ICX 7750 and ICX 7450 devices have an 8 minute default and minimum timer. The ICX 7250 device has a default and minimum timer of 3 minute.

Enable optical monitoring for specific ports.

To enable optical monitoring on a specific port with the default polling interval, use the following command.
```
device(config)# interface ethernet 1/1/1
device(config-if-e10000-1/1/1)# optical-monitor
```
To enable optical monitoring on a range of ports with the default polling interval, use the following command.
```
device(config)# interface ethernet 1/1/1 to 1/1/2
device(config-mif-e10000-1/1/1-1/1/2)# optical-monitor
```

Verify the alarm and warning interval.

device(config)# show optic-timer 1/1/4 
Optical monitoring timer Interval for Port 1/1/4 is 8 mins

Verify media device configuration.
