Port Statistics and Optical Performance Statistics. The 10/100M2 supports reporting of utilization, port and optical performance statistics. Port statistics are available for 38 different parameters for the RJ-45 and fiber ports. Additionally, full optical performance statistics are available on SFP fiber transceivers with a digital diagnostic interface.

• Fault Detection. The 10/100M2 detects and indicates link faults, dying gasp and other critical events. The 10/100M2 also supports Unidirectional Link Fault Detection that indicates faults in either direction of the fiber link.
• Remote Loopback. Remote Loopback is used for fault localization and link performance testing. When a 10/100M2 port is in loopback mode, all received link traffic is looped back and transmitted back unaltered. The statistics from the 10/100M2 port and the remote link partner can be compared for consistency.
• IEEE 802.3ah operations, administration and maintenance. The 10/100M2 supports the IEEE 802.3ah Link OAM standard with Fault Detection, Performance Monitoring and Remote Loopback for Ethernet in the First Mile (EFM) access links.
• Port bandwidth control and port access control. The enhanced Bandwidth Control feature controls bandwidth between the fiber and RJ-45 ports in 64Kbps increments from 64K to Full Line Speed.
• Performance Monitoring. 802.3ah Performance Monitoring tools are used for the detection and notification of link performance (quality) faults. Ethernet data performance can deteriorate slowly over time, and the 10/100M2 allows the setting of error-per-second thresholds with event notification for early indication of issues that may be resolved prior to loss of service.
