Ethernet OAM Commands

Use these commands to use the link monitoring protocol IEEE 802.3ah Link Layer Ethernet
OAM (Operations, Administration and Maintenance).
16.1 IEEE 802.3ah Link Layer Ethernet OAM Implementation
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 PDU's 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.
16.2 Command Summary
The following section lists the commands for this feature.
