Ethernet OAM

The IEEE Std 802.3ah Operations, Administration, and Maintenance (OAM) sublayer provides mechanisms useful for monitoring link operation such as remote fault indication and remote loopback control. In general, OAM provides network operators the ability to monitor the health of the network and quickly determine the location of failing links or fault conditions.

OAM information is conveyed in Slow Protocol frames called OAM Protocol Data Units (OAM PDUs). OAM PDUs contain the appropriate control and status information used to monitor, test and troubleshoot OAM-enabled links.

The addition of Ethernet OAM support in IxOS involves the following:

A list of load modules and the Ethernet OAM statistics they can generate are provided in Ethernet OAM Statistics. Ethernet OAM statistics counters are defined in Description of Statistics.
