Ethernet OAM Commands

Use these commands to use the link monitoring protocol IEEE 802.3ah Link Layer Ethernet OAM
(Operations, Administration and Maintenance).
27.1 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.
27.2 Command Summary
The following section lists the commands for this feature.

DESCRIPTION
Displays OAM configuration details and operational status
of the specified ports.
Displays the number of OAM packets transferred for the
specified ports.
Displays the configuration details of each OAM activated
port.
Enables Ethernet OAM on the Switch.
Disables Ethernet OAM on the Switch.
Initiates a remote-loopback test from the specified port by
sending Enable Loopback Control PDUs to the remote
device.
Terminates a remote-loopback test from the specified port
by sending Disable Loopback Control PDUs to the remote
device.
