36.1 OAM Overview

Link layer Ethernet OAM (Operations, Administration and Maintenance) as described in IEEE
802.3ah is a link monitoring protocol. It utilizes OAM Protocol Data Units or OAM PDUs to transmit
link status information between directly connected Ethernet devices. Both devices must support
IEEE 802.3ah. Because link layer Ethernet OAM operates at layer two of the OSI (Open Systems
Interconnection Basic Reference) model, neither IP or SNMP are necessary to monitor or
troubleshoot network connection problems.
The Switch supports the following IEEE 802.3ah features:
• Discovery - this identifies the devices on each end of the Ethernet link and their OAM
configuration.
• Remote Loopback - this can initiate a loopback test between Ethernet devices.

36.1.1 What You Can Do

• Use the OAM Status screen
which Ethernet OAM is enabled.
• Use the OAM Configuration screen
Switch.
• Use the OAM Remote Loopback screen
loopback tests.
