protocols can be monitored:
•ESCON
•Fibre Channel (1 Gbps only)
•FICON
•Gigabit Ethernet
•ISC compatibility mode
•SONET
•SDH
When monitoring is enabled on the transparent interface, it is automatically enabled on the
corresponding wave interface.
For Gigabit Ethernet, Fibre Channel, and FICON, the Cisco ONS 15530 monitors the code violation and
running disparity error count.
For SONET errors, the CiscoONS 15530 monitors the SONET section overhead only, not the SONET
line overhead. Specifically, the CiscoONS 15530 monitors the B1 byte and the framing bytes. The
system can detect the following defect conditions:
•Loss of Light
•Loss of Lock (when the clock cannot be recovered from the rec eived data str ea m)
•Severely Errored Frame
•Loss of Frame
