EFM configuration
forwarding address is not its purpose, but the road back to its original The
end.
Remote loopback is controlled by remote Loopback Control OAMPDU
remote loopback or remote loopback operation to cancel the function can
be used to detect the link quality and positioning of link failure.
Remote access
to MIB variable
function
EFM entities can interact with Variable Request / Response OAMPDU far
end of the entity to obtain the MIB variable value. Include Ethernet MIB
variable chain on the road all the performance parameters and error
statistics. It provides a local EFM physical entities on the far side of the
general performance and error detection mechanisms.
Description:
We said so to the EFM port functions as "EFM Entities.
34.1.2 EFM Protocol Packets
EFM working in the data link layer, the protocol packet is called OAMPDU (OAM Protocol
Data Units, OAM protocol data unit).EFM is through regular interaction between the device
OAMPDU to report link status, enabling network administrators to effectively manage the
network.
Table 34-2 EFM protocol packets
EFM entity status for the information (including local information, the
remote information and custom information) sent to the remote entity
EFM, EFM connections to maintain.
Event Notification
OAMPDU
Generally used for link monitoring on local and remote connected
EFM physical link failures in the warning.
Mainly use for remote loopback control in order to control the EFM
loopback state of remote device. The packet has the information of
enabling or disabling loopback .Enabling or disabling remote loopback
based on this information.
Variable Request /
Response OAMPDU
Mainly used for remote MIB variable values, in order to achieve the
end of the remote state prosecution.
