Configuring the Ethernet EFM OAM for MA5612

 Configuring the Ethernet EFM OAM for Huawei MA5612

Ethernet in the First Mile (EFM) OAM is defined in IEEE 802.3ah to make the Ethernet physicallayer specifications in respect of the user access part and the Ethernet OAM in respect of the access part. Ethernet EFM OAM is used for the link detection of the last mile and it is the linklevel OAM.

Prerequisite

l Network devices and lines must be in the normal state.

l The OLT must support the Ethernet EFM OAM function.

Context

Huawei OLT OAM is a key method of reducing network maintenance cost.

Ethernet EFM OAM is defined in IEEE 802.3ah Clause 57 and it is a key component of Ethernet OAM. Ethernet EFM OAM provides a mechanism for monitoring links, such as remote defect indication (RDI) and remote loopback control. It is an L2 mechanism, as a complement to the higher layer applications.

Networking

Figure 1 shows the example network of the Ethernet EFM OAM function.

Procedure

Step 1 Run the efm oam mode command to configure the Ethernet EFM OAM mode of the port.

l The default Ethernet EFM OAM mode of the port is the active mode.

l After the Ethernet EFM OAM function is enabled on the port, the mode of the port cannot

be changed.

l When the Ethernet EFM OAM mode of both the local and peer devices is the passive mode, the Ethernet EFM OAM function cannot be enabled. The Ethernet EFM OAM function can be enabled only when the Ethernet EFM OAM mode of the device at one end is the active mode.

Step 2 Run the efm oam enable command to enable the Ethernet EFM OAM function on the port.

By default, the Ethernet EFM OAM function on the port is disabled.

Step 3 (Optional) Run the efm loopback command to configure the start, end, and control parameters for the Ethernet EFM OAM loopback on the port.

l By default, the Ethernet EFM OAM loopback is not performed.

l After the Ethernet EFM OAM loopback is started, all the services are interrupted.

Step 4 Run the efm error-frame command to set error frame parameters and the status of the error frame alarm function. In this manner, the link signals and data quality can be monitored.

Step 5 Query the configuration information about the Ethernet EFM OAM function.

l Run the display efm oam status command to query the status of the Ethernet EFM OAM

function.

l Run the display efm oam event config command to query the parameters of the Ethernet

EFM OAM event.

Example

Assume that the Ethernet EFM OAM mode is the passive mode, the error frame alarm function is enabled, the local error frame window is 1, and the error frame threshold is 0. To enable the Ethernet EFM OAM function on port 0/4/1, do as follows:

huawei(config)#efm oam mode 0/4/1 passive

huawei(config)#efm oam 0/4/1 enable

huawei(config)#efm error-frame 0/4/1 notification enable

huawei(config)#efm error-frame 0/4/1 period 1

huawei(config)#efm error-frame 0/4/1 threshold 0

Run the display efm oam status command to query the status of the Ethernet EFM OAM

function.

huawei#display efm oam status

{ frameid/slotid/portid<S><Length 1-15> }:0/4/1

{ local<K>|remote<K> }:local //Query the local Ethernet OAM status. If you need

to query the remote Ethernet OAM status, select remote.

Command:

display efm oam status 0/4/1 local

Admin Status : Enable //The Ethernet OAM function is

enabled.

Operation Status : Operational

OAM Mode : Passive //The local Ethernet OAM mode is the

passive mode.
