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.
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.
----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:
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.
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.
