Critical Event
The devices are able to receive Information OAMPDUs carrying the critical link events listed in
8.
The devices are able to send Information OAMPDUs carrying Dying Gasp events when the device is
rebooted or relevant ports are manually shut down.
The devices are unable to send Information OAMPDUs carrying Critical Events.
IRF physical ports do not support OAM-related functions.
Remote loopback
Remote loopback is available only after the Ethernet OAM connection is established. With remote
loopback enabled, the Ethernet OAM entity in active mode sends non-OAMPDUs to its peer. After
receiving these frames, the peer does not forward them according to their destination addresses.
Instead, it returns them to the sender along the original path.
Remote loopback enables you to check the link status and locate link failures. Performing remote
loopback periodically helps to detect network faults promptly. Furthermore, performing remote
loopback by network segments helps to locate network faults.

Standards and protocols

Ethernet OAM is defined in IEEE 802.3ah (Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) Access Method and Physical Layer Specifications.
