Configuring Basic EFM OAM Functions
You can configure basic EFM OAM functions to check link connectivity between two directly connected devices.
Usage Scenario
With the development of Ethernet services, carriers are increasingly focusing on device maintainability. During Ethernet expansion to MANs or WANs, there is an urgent need for implementing OAM on transport networks. Maintenance methods for link-level Ethernet, however, are limited. Ethernet OAM resolves this issue. The hierarchical and layered network architecture requires hierarchical and layered Ethernet OAM. The traditional Ethernet management function is implemented at the layers upper than the network layer.
EFM OAM is link-level OAM and defines Ethernet physical layer specifications and implements Ethernet OAM for user access. On a MAN, EFM OAM is usually applied between directly connected CEs and PEs, which ensures the reliability and stability of connections between the user network and carrier network. To check link connectivity between two directly connected devices on the network shown in Figure 1, configure basic EFM OAM functions.
- Enabling EFM OAM Globally
- You must enable EFM OAM globally before configuring EFM OAM functions.
- Configuring an EFM OAM Working Mode for an Interface
- An EFM OAM working mode is an attribute of an interface enabled with EFM OAM. An interface works in either active or passive mode.
- (Optional) Setting OAM PDU Parameters
- You can set the maximum OAM PDU size, interval at which OAM PDUs are sent, and interval at which OAM PDUs are received to effectively control OAM PDU transmission.
- Enabling EFM OAM on an Interface
- Point-to-point EFM link detection can be performed only after EFM OAM is enabled on the interfaces at both ends of a link. Perform the following steps at both ends of a link:
- Verifying the Basic EFM OAM Function Configuration
- After configuring basic EFM OAM functions, verify the configurations.
