Parameters
service-instance instance-id: Specifies the service instance ID in the range of 1 to 32767.
mep mep-id: Specifies a MEP by its ID in the range of 1 to 8191.
Usage guidelines
Follow these guidelines when you use the command:

· If the MEP belongs to an MA that carries the VLAN attribute, configurations on a member port of an aggregate interface take effect only when the member port leaves the aggregation group.
Examples

Parameters
md md-name: Specifies the name of an MD, which is a string of 1 to 43 characters that can contain letters, numbers, and special characters such as grave accent (`), tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk (*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), colon (:), semicolon (;), quotation mark ('), comma (,), period (.), and slash (/).
index index-value: Specifies an MD index in the range of 1 to 4294967295. If you do not specify this option, the system automatically assigns the smallest index number that is not in use. As a best practice, use the index automatically assigned by the system.
level level-value: Specifies an MD level in the range of 0 to 7.
md-id: Specifies the MD name carried by packets sent by the MEP. If you do not provide this keyword, the MD name is represented by md-name.
dns dns-name: Specifies an MD name in the format of DNS name, where dns-name represents the DNS name.
mac mac-address subnumber: Specifies an MD name containing the MAC address and an integer. The mac-address argument represents the MAC address of the MD, and the subnumber argument is in the range of 0 to 65535.
none: Specifies that no MD name is carried in the packets sent by the MEP.
Usage guidelines
An MD name must be in compliant with the specifications in IEEE802.1ag-2007.
You can create only one MD with a specific level. MD cannot be created if you enter an invalid MD name or an existing MD name or the MD index is in use.
When deleting an MD, you will also delete the configurations related to that MD.
Examples
# Create an MD named test_md1, with its level being 3.
<Sysname> system-view
[Sysname] cfd md test_md1 level 3
# Create an MD named test_md2, and the MD name carried in the packet sent by the MEP comprises the MAC address 1-1-1 and integer 1.

Parameters
mep mep-id: Specifies the MEP ID, in the range of 1 to 8191.
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.
outbound: Creates an outward-facing MEP.
Usage guidelines
In creating a MEP, the service instance you specified defines the MD and MA to which the MEP belongs.
You cannot create a MEP if the MEP ID is not included in the MEP list of the relevant service instance.
Follow these guidelines when you use the command:
· Configurations in Ethernet interface view or aggregate interface view take effect only on the current interface.
· If the MEP belongs to an MA that does not carry the VLAN attribute, configurations on a member port of an aggregate interface take effect only on the current member port.
· If the MEP belongs to an MA that carries the VLAN attribute, configurations on a member port of an aggregate interface take effect only when the member port leaves the aggregation group.
Examples
# Configure a MEP list in service instance 5, and create inward-facing MEP 3 in service instance 5 on GigabitEthernet 1/2/0/1.
<Sysname> system-view
[Sysname] cfd md test_md level 3
[Sysname] cfd service-instance 5 ma-id vlan-based md test_md vlan 100

Parameters
meplist mep-list: Specifies a space-separated list of up to 10 MEP items. Each item specifies a MEP ID or a range of MEP IDs in the form of mep-id 1 to mep-id 2. The value range for the MEP ID is 1 to 8191. The mep-id 2 must be equal to or greater than mep-id 1.
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.
Usage guidelines
A MEP list is a collection of local MEPs allowed to be configured and the remote MEPs to be monitored in the same MA.
Before creating a MEP list, create the relevant MD and service instance.
After you delete a MEP list, all local MEP configurations based on this list are deleted.
Examples
# Create a MEP list that includes MEP 9 through MEP 15 in service instance 5.
<Sysname> system-view
[Sysname] cfd md test_md level 3

Parameters
service-instance instance-id: Specifies the service instance ID in the range of 1 to 32767.
ma-id: Creates an MA.
icc-based ma-name: Specifies that an MA is identified by an ICC. The ma-name argument is a string of 1 to 13 characters. An MA name must be compliant with the specifications in IEEE802.1ag-2007
integer ma-num: Specifies that an MA is identified by an integer, where the ma-num argument is in the range of 0 to 65535.
string ma-name: Specifies that an MA is identified by a string, where the ma-name argument is string of 1 to 45 characters that can contain letters, numbers, and special characters such as grave accent (`), tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk (*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), colon (:), semicolon (;), quotation mark ('), comma (,), period (.), and slash (/).
vlan-based [ vlan-id ]: Specifies that an MA is identified by a VLAN ID, where the vlan-id argument is in the range of 1 to 4094. If you do not provide the vlan-id argument, the VLAN ID specified by vlan vlan-id is used. If the vlan vlan-id option is not provided, you must specify the vlan-id argument for the vlan-based [ vlan-id ] option.
ma-index index-value: Specifies an MA index in the range of 1 to 4294967295. If you do not specify this option, the system automatically assigns the smallest index number that is not in use. As a best practice, use the index automatically assigned by the system.
md md-name: Specifies the name of an MD. The md-name argument is a string of 1 to 43 characters that can contain letters, numbers, and special characters such as grave accent (`), tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk (*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), colon (:), semicolon (;), quotation mark (’), comma (,), period (.), and slash (/).
vlan vlan-id: Specifies the VLAN that the MA serves. The value range for the vlan-id argument is 1 to 4094.
Usage guidelines
You must create the relevant MD before creating a service instance.
Deleting a service instance also deletes the configurations related to that service instance.
Deleting a service instance not only removes the connection between the service instance and the relevant MA, but also deletes the MA.
When you create a service instance, follow these restrictions and guidelines:
· A service instance is indicated by an integer to represent an MA in an MD. An MA index uniquely identifies a specific MA in an MD. An MA index can be used in different MDs.
· With the vlan-based [ vlan-id ] or vlan vlan-id option, the command creates an MA carrying the VLAN attribute. If you do not specify the option, the command creates an MA carrying no VLAN attribute.
Examples
# Create a level-3 MD named test_md and create service instance 5, in which the MA is identified by a VLAN and serves VLAN 100.

[Sysname] cfd md test_md level 3
