show interfaces diagnostics optics (SONET)

(T-series routers only) On OC768 SONET interfaces, display 300-pin Multisource Agreement (MSA) diagnostics data and alarms. For OC192 and OC768 interfaces on the 4-port OC-192c PIC, display XFP diagnostics and data alarms.

Options

Additional Information

300-pin Multisource Agreement (MSA) optics, XENPAK MSA optics, and XFP optics are supported. The 300-pin MSA tool kit polls the PIC and the XENPAK driver polls the XENPAK transceiver in 1-second intervals for diagnostics data, alarms, and warnings and stores them into memory. The alarms will not cause the links to go down or the LEDs to change color or generate SNMP traps. Changes in alarm and warning status will generate system log messages.

Thresholds that trigger a high alarm, low alarm, high warning, or low warning are set by the transponder vendors. Generally, a high alarm or low alarm indicates that the optics module is not operating properly. This information can be used to diagnose why a PIC is not working.
