Configuring Ethernet OAM
Default Ethernet OAM Configuration
• Ethernet OAM is disabled on all interfaces.
• When Ethernet OAM is enabled on an interface, link monitoring is automatically turned on.
• Remote loopback is disabled.
• No Ethernet OAM templates are configured.
Ethernet OAM Configuration Guidelines
• The switch does not support monitoring of egress frames sent with cyclic redundancy code (CRC)
errors. The ethernet oam link-monitor transmit crc interface-configuration or
template-configuration commands are visible but are not supported on the switch. The commands
are accepted, but are not applied to an interface.
• For a remote failure indication, the switch does not generate Link Fault or Critical Event OAM
PDUs. However, if these PDUs are received from a link partner, they are processed. The switch
supports generating and receiving Dying Gasp OAM PDUs when Ethernet OAM is disabled, the
interface is shut down, the interface enters the error-disabled state, or the switch is reloading. The
switch can also generate and receive Dying Gasp PDUs based on loss of power. The PDU includes
a reason code to indicate why it was sent.
• The switch does not support Ethernet OAM on ports that belong to an EtherChannel.
