The 802.3ah standard is a link oriented (port to port) protocol, i.e., it operates on a port level and
communicates with the neighbor device directly connected to its port.
R Class series can communicate with any neighbor device supporting this protocol.
The major capabilities of 802.3ah are:
1.
Discovery
: detects the endpoints of a link and its OAM capabilities
2.
Remote Fault Detection
: allows one endpoint to convey severe events and failure conditions
to its OAM link partner (Link fault, Dying Gasp, specific critical events)
3.
Link Performance Monitoring
: detection and notifications of different link faults. Event
notification is delivered to the link partner when one of these events is detected on the link:
Frame Error events, Frame Period Error events, Symbol Period Error events, Event Seconds
Summary
4.
Remote Loopback
: can be used to put the remote port in loopback mode, useful for data-
path test
5.
MIB variable retrieval
: collecting performance statistics. A MIB (Management Information
Base) is a collection of variables which are deployed for measuring the link capability to
support the defined SLA.
6.
Verification of link port status
7.
Simultaneous operation on multiple ports
A typical link OAM scenario is shown below:

Link OAM Port Configuration
This section allows the user to inspect the current Link OAM port configurations and change them as
well.
