How to turn on this feature? Chassis supports it (3750). Transceiver supports it, as Digital Optical Monitoring Compatibility Matrix said (GLC-ZX-SM). But "sh inter gi1/0/25 transceiver detail" show me "Diagnostic Monitoring is not implemented." message. What I should do to implement collecting DOM info?
And second. Is 6500 with IOS supports this feature? CatOS supports, as Cisco site said. But IOS (now we have 12.2(18)SXF line) shows me message "Diagnostic Monitoring Data is not available." (also GLC-ZX-SM)
