In addition to checking the current status of an optic via the 'show interfaces diagnostics optics <interface-name> ' command, it may also be necessary to examine more detailed information regarding the optics or the history of the alarms on the optic.

More detailed information and alarm history can be obtained by querying the hardware which is hosting the optic, basically FPC for MX304.

Target will be FPC0, 1, 2...19

Once the hardware target is determined, ask the hardware for the index assigned to the SFP or SFP+ you want to look at. These are both stored in the same table:

request pfe execute command 'show picd xcvr summary' target <target>

Sample output:

labroot@jtac-mx304-r2001-re0> request pfe execute command "show picd xcvr summary" target fpc0 

SENT: Ukern command: show picd xcvr summary
