Brocade FastIron Ethernet Switch Administration Guide - Manual (Page 212)

NOTE
A Brocade ICX 6650 device allows all ports to support Digital Optical Monitoring (DOM).
Enabling digital optical monitoring
To enable optical monitoring on all Brocade-qualified optics installed in the device, use the following
command.
device(config)#optical-monitor
To enable optical monitoring on a specific port, use the following command.
device(config)#interface ethernet 1/1
device(config-if-e10000-1/1)#optical-monitor
To enable optical monitoring on a range of ports, use the following command.
device(config)#interface ethernet 1/1 to 1/2
device(config-mif-e10000-1/1-1/2)#optical-monitor
Syntax: [no] optical-monitor
Use the no form of the command to disable digital optical monitoring.
Setting the alarm interval
You can optionally change the interval between which alarms and warning messages are sent. For all
Brocade devices except the ICX 6650, the default interval is three minutes. The minimum and default
interval for the ICX 6650 is eight minutes and a value of one through seven minutes generates an
error message. To change the interval, use the following command.
device(config)#interface ethernet 1/1 to 1/2
device(config-mif-e10000-1/1-1/2)#optical-monitor 10
Syntax: [no] optical-monitor [ alarm-interval ]
For alarm-interval, enter a value between 1 and 65535. For the ICX 6650 enter a value between 8 and
65535. Enter 0 to disable alarms and warning messages.
NOTE
The commands no optical-monitor and optical-monitor 0 perform the same function. That is, they
both disable digital optical monitoring.
Displaying information about installed media
Use the show media , show media slot , and show media ethernet commands to obtain information
about the media devices installed per device, per slot, and per port. The results displayed from these
commands provide the Type, Vendor, Part number, Version and Serial number of the SFP, SFP+, or
XFP optical device installed in the port. If there is no SFP, SFP+, or XFP optical device installed in a
port, the "Type" field will display "EMPTY".
On ICX 6430 and ICX 6450 devices, 1G copper ports will always be shown with the type as 1G M-C
(Gig-Copper), even if the ports are not connected.
