Optional) Creating The Default Md - Huawei Quidway S3700 Series Configuration Manual

Quidway S3700 Series Ethernet Switches
Configuration Guide - Reliability
Context
Do as follows on the switch that requires Ethernet CFM:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
cfm md md-name [ format { no-md-name | dnsname-and-mdname | mac-address | md-
name } ] [ level level ]
An MD is created and the MD view is displayed.
Parameters format, no-md-name, dnsname-and-mdname, and mac-address can be used only
on the device running IEEE Standard 802.1ag-2007.
By default, an MD is at level 0. Level 0 is the lowest level.
Repeat Step 2 to create more MDs. Up to 16 MDs can be created on the S3700.
----End

4.8.5 (Optional) Creating the Default MD

The default MD must be of a higher level than all MDs to which MEPs on the local device
belong. In addition, the default MD must be of the same level as the high-level MD. The high-
level CCMs are transmitted through the default MD.
Context
Do as follows on each S3700 device that requires Ethernet CFM:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
cfm default md [ level level ]
The default MD is created and the default MD view is displayed.
Issue 01 (2011-10-26)
NOTE
The 802.1ag packets from a lower-level MD are discarded when being transmitted through the same level
MD or a higher-level MD. The 802.1ag packets from a higher-level MD can be transmitted through a lower-
level MD.
NOTE
IEEE 802.1ag has two versions, that is, IEEE 802.1ag Draft 7 and IEEE Standard 802.1ag-2007. The cfm
default md command can be used only on the device complying with IEEE Standard 802.1ag-2007. Before
using the cfm default md command, you must use the cfm version command to set the IEEE 802.1ag
version to IEEE Standard 802.1ag-2007.
