Predefined user roles
network-admin
Parameters
size size-value: Specifies the size of the buffer used to store the auto-detection result, in the range of 1 to 100 (in terms of auto-detection times). The default value is 5, which means the buffer stores the results of the recent five auto-detections.
Usage guidelines
This command enables the source MEP to send LTMs when it fails to receive CCMs from the target MEP within 3.5 times the sending interval. The destination of the LTMs is the target MEP, and the TTL field value is 255. Based on the returned LTRs, the fault source can be located on the faulty link.
If you disable automatic LTM sending, the content stored in the buffer will be removed.
Examples
# Enable automatic LTM sending, and set the size of the buffer used to store the auto-detection result to 100 (in terms of auto-detection times).

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

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 take effect only on the current interface.
· Configurations in aggregate interface view take effect only on the current aggregate interface.
· If the MEP belongs to an MA that does not carry the VLAN attribute, configurations on a member port of an aggregation group 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 aggregation group take effect only when the member port leaves the aggregation group.

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.

Predefined user roles
network-admin
Parameters
cc-expire: Triggers port collaboration when continuity check expires.
rdi: Triggers port collaboration when the CCMs with the RDI flag bits set are received.
block: Blocks the port by changing its link layer protocol state to DOWN (CFD). The port cannot send or receive any data packets.
shutdown: Shuts down the port by changing its physical state to CFD DOWN. The port cannot send or receive any data packets or protocol packets.
Usage guidelines
If a port is blocked by CFD, it can automatically come up when the link recovers.
If a port is shut down by CFD, it cannot automatically come up when the link recovers.
· If port collaboration is triggered by continuity check expiration, you must execute the undo shutdown or undo cfd port-trigger { cc-expire | rdi } action command to bring up the port.
· If port collaboration is triggered by CCMs with the RDI flag bits set, you must execute the undo cfd port-trigger { cc-expire | rdi } action command to bring up the port.
You can specify multiple triggering events for an interface. All the triggering events can take effect. When you specify multiple triggered actions for a triggering event on an interface, the most recent configuration takes effect.
The command takes effect only on the ports with outward-facing MEPs configured.
Configurations in Ethernet interface view take effect only on the current interface.
Configurations in aggregate interface view take effect only on the current aggregate interface.
If the MEP belongs to an MA that does not carry the VLAN attribute, configurations on a member port of an aggregation group 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 aggregation group take effect only when the member port leaves the aggregation group.
Examples
# Specify the triggering event as cc-expire and the triggered action as block for port collaboration on Twenty-FiveGigE 1/0/1.
<Sysname> system-view
[Sysname] interface twenty-fivegige 1/0/1

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.
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
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.
An MD name must be in compliant with the specifications in IEEE802.1ag-2007.
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.
You must create the relevant MD before creating a service instance with the MD name.
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.
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> system-view
[Sysname] cfd md test_md level 3

Parameters
interface interface-type interface-number: Specifies a port by its type and number. If you do not specify this option, the command displays MP information for all ports.
Usage guidelines
The output is arranged by port name. On a port, the output shows MPs that serve VLANs, and then shows MPs that do not serve any VLANs. The MPs that serve VLANs are displayed in the ascending VLAN ID order. Within the same VLAN, the output is in the order of MIPs and MEPs (from high to low level). The MEPs that do not serve any VLANs are displayed by level (from high to low).
Examples
# Display the MP information on all ports.
