DOT3-OAM-MIB
About this MIB
Ethernet Operation, Administration, and Maintenance (OAM) is a tool that monitors Layer 2 link status. It checks the connectivity of a link by sending OAM protocol data units (OAMPDUs) and reports to the network administrators when a link error occurs.
This MIB focuses on Ethernet OAM functions.

Recommended action
To resolve the issue, check the value of the EventLogType field in the notification.
· If the value is 256, a Link Fault event has occurred on the local or remoted end. Check whether the interface is shut down.
¡ If the interface is shut down, execute the undo shutdown command to resolve the issue.
¡ If the interface is not shut down, check the physical link.
· If the value is 257, a Dying Gasp event has occurred on the local or remoted end. Check whether the device is rebooting.
¡ If the device is rebooting, wait for the device to start and then check whether the issue has been resolved.
¡ If the device is not rebooting, collect related information and then contact H3C Support.
· If the value is 258, a Critical Event has occurred on the remote end. Check the peer device.
