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.
----End

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.
Max OAM PDU Size : 1514

Example of Configuring a VTY User Interface on Huawei S9300

Example of Configuring a VTY User Interface on Quidway S9300:
Networking Requirements
A user can use the VTY interface to log in to a remote device using Telnet. The device
administrator can configure the attributes of the VTY user interface to ensure device security.
In this example, the level of VTY users is 2. The password authentication mode and
authentication password huawei2012 are configured for VTY users to log in to the device. Only the user whose IP address is 10.1.1.1 can log in to the device.
If a user logs in to the device and does not perform an operation within 30 minutes, the user's terminal disconnects from the device
.
Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the maximum number of concurrent VTY user interfaces to 8.
2. Configure restrictions on call-in and call-out permissions on the VTY user interface to
allow users at a specified address or address segment to log in to the device.
3. Configure terminal attributes on the VTY user interface.
4. Configure the user level on the VTY user interface.
5. Configure the authentication mode and password of the VTY user interface.

Procedure, use the Huawei S9303 for the example.
Step 1 Configure the maximum number of concurrent VTY user interfaces.
<Quidway> system-view
[Quidway] user-interface maximum-vty 8

Step 2 Configure restrictions on call-in and call-out permissions on the VTY user interface.
[Quidway] acl 2000
[Quidway-acl-basic-2000] rule deny source 10.1.1.1 0
[Quidway-acl-basic-2000] rule permit source any
[Quidway-acl-basic-2000] quit
[Quidway] user-interface vty 0 7
[Quidway-ui-vty0-7] acl 2000 inbound

Step 3 Configure terminal attributes on the VTY user interface.
[Quidway-ui-vty0-7] shell
[Quidway-ui-vty0-7] idle-timeout 30
[Quidway-ui-vty0-7] screen-length 30
[Quidway-ui-vty0-7] history-command max-size 20

Step 4 Configure the user level on the VTY user interface.
[Quidway-ui-vty0-7] user privilege level 2

Step 5 Configure the authentication mode and password of the VTY user interface.
[Quidway-ui-vty0-7] authentication-mode password
[Quidway-ui-vty0-7] set authentication password cipher huawei2012
[Quidway-ui-vty0-7] quit
After the VTY user interface is configured, users can log in to the device in the password
authentication mode using Telnet to maintain the device locally or remotely. For details on how to log in to the device see 4.2.2 Logging In to the Device Through Telnet.

Step 6 Verify the configuration.
# Connect the terminal to the device using Telnet, and verify that the new password is valid.
# Use 10.1.1.1 to log in to the device using Telnet. The login fails.
# Run the user-interface vty 0 7 command to enter the VTY interface view, and run the display this command to check the configurations on the VTY interface.
[Quidway] user-interface vty 0 7
[Quidway-ui-vty0-7] display this
#
