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:

·     Configurations in Ethernet 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.

In an Ethernet network, you can enable CCM sending only on Layer 2/Layer 3 Ethernet interfaces and Layer 2 aggregate interfaces.

In an MPLS Layer 2 VPN, you can enable CCM sending only on Layer 3 Ethernet interfaces, Layer 3 Ethernet subinterfaces, Layer 3 aggregate interfaces, Layer 3 aggregate subinterfaces, and Layer 2 Ethernet service instances.

Parameters

service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.

mep mep-id: Specifies the source MEP by its ID in the range of 1 to 8191.

target-mac mac-address: Specifies the target MEP by its bridge MAC address, which is in the format of H-H-H.

target-mep target-mep-id: Specifies the target MEP by its ID in the range of 1 to 8191.

dot1p dot1p-value: Specifies an 802.1p priority for CCM frames. The value range for the dot1p-value argument is 0 to 7. The default value is 7.

Usage guidelines

The two-way LM function measures the frame loss between the source and target MEPs by using CCMs. The source MEP calculates the number of lost frames according to the counter values of two consecutive CCMs received (the current CCM and the previous CCM).

To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.

For the two-way LM function to take effect, you must configure it on both the local and peer devices.

If the frame counting mode is dot1p-based, you must specify the dot1p dot1p-value option. If the frame counting mode is port-based, do not specify the dot1p dot1p-value option.

To modify two-way LM settings for a source MEP, disable two-way LM and then reconfigure the function for the source MEP.

The two-way LM detection interval is the CCM interval. Before configuring two-way LM, configure the CCM interval field value to be greater than 2.

One-way LM and two-way LM cannot be configured at the same time for one source MEP. If you have configured short-period one-way LM or continual one-way LM, you can configure two-way LM only after you disable continual one-way LM or short-period one-way LM ends. If you have configured two-way LM, you can configure short-period one-way LM or continual one-way LM only after disable two-way LM.

To display the two-way LM result, use the display cfd dlm history command on the device where the source MEP or target MEP resides.

Two-way LM can be configured only in Layer 2 VPNs. MEPs created in a Layer 2 Ethernet service instance do not support two-way LM.

Examples

# Enable the continual two-way LM function to measure the frame loss between source MEP 1101 and target MEP 2001 in service instance 1.

<Sysname> system-view

[Sysname] cfd dlm continual service-instance 1 mep 1101 target-mep 2001

upper-limit upper-limit: Specifies the upper limit in percentage, in the range of 0 to 100. It can contain a maximum of 8 digits, including the dot (.), for example, 1.000001.

Usage guidelines

This command takes effect only after you configure continual two-way LM.

When the packet loss ratio for the source MEP or target MEP reaches or exceeds the upper limit, the system displays a message about the situation.

When the packet loss ratios for both the source MEP and target MEP reach or fall below the lower limit, the system displays a message about the situation.

Examples

# Configure the lower limit and upper limit as 0.2% and 0.8%, respectively, for source MEP 1101 in service instance 1.

Usage guidelines

The short-period two-way DM function measures the two-way frame delay between the source and target MEPs by using DMM frames and DMR frames.

To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.

Short-period two-way DM and continual two-way DM cannot be configured at the same time for one source MEP. If you have configured continual two-way DM, you can configure short-period two-way DM only after you disable continual two-way DM. If you have configured short-period two-way DM, you can configure continual two-way DM only after the short-period two-way DM ends.

Usage guidelines

Continual two-way DM continually sends DMM frames at a configurable interval. It measures the two-way frame delay between the source and target MEPs after receiving the returned DMR frames.

To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.

To modify continual two-way DM settings for a source MEP, disable continual two-way DM and then reconfigure the function for the source MEP.

Short-period two-way DM and continual two-way DM cannot be configured at the same time for one source MEP. If you have configured continual two-way DM, you can configure short-period two-way DM only after you disable continual two-way DM. If you have configured short-period two-way DM, you can configure continual two-way DM only after the short-period two-way DM ends.

To display the continual two-way DM result, use the display cfd dm two-way history command on the device where the source MEP resides.

Inward-facing MEPs created in an Ethernet network do not support continual two-way DM.

Examples

# Enable the continual two-way DM function to test the two-way frame delay between source MEP 1101 and target MEP 2001 in service instance 1.

Parameters

dot1p-based: Counts packets by 802.1p priority.

port-based: Counts packets by interface.

Usage guidelines

To obtain accurate test results, configure the same frame counting mode on the source MEP and target MEP.

If the frame counting mode is dot1p-based, you must specify the dot1p dot1p-value option when configuring the cfd slm, cfd slm continual, and cfd dlm continual commands. If the frame counting mode is port-based, do not specify the dot1p dot1p-value option when configuring the cfd slm, cfd slm continual, and cfd dlm continual commands.

If LM has been configured for a MEP, the frame counting mode on the interface where the MEP resides cannot be modified.

This command can be configured only in MPLS Layer 2 VPNs.

Examples

# Configure the frame counting mode for LM as dot1p-based on HundredGigE 1/0/1.1.

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.

The outward-facing MEP on a hardware CC-supported card does not automatically send LTMs.

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.

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.

vlan vlan-id: Specifies a VLAN by its ID in the range of 1 to 4094.

service-vid vlan-id: Specifies an outer VLAN (SVLAN) by its ID in the range of 1 to 4094.

customer-vid vlan-id: Specifies an inner VLAN (CVLAN) by its ID in the range of 1 to 4094.

inbound: Creates an inward-facing MEP.

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.

In an Ethernet network, you can create MEPs only on Layer 2 Ethernet interfaces, Layer 2 aggregate interfaces, Layer 3 Ethernet interfaces, and Layer 3 Ethernet subinterfaces.

In an MPLS Layer 2 VPN:

·     For L2VPN networking, you can create MEPs only on Layer 3 Ethernet interfaces, Layer 3 Ethernet subinterfaces, Layer 3 aggregate interfaces, Layer 3 aggregate subinterfaces, and Layer 2 Ethernet service instances.

·     For VPLS networking, you can create MEPs only on Layer 3 Ethernet interfaces, Layer 3 Ethernet subinterfaces, Layer 3 aggregate interfaces, and Layer 3 aggregate subinterfaces.

·     Only one inward-facing MEP can be configured for a CFD service instance.

·     A MEP can only be configured on an AC interface to detect PW connectivity.

To specify the VLAN ID when creating a MEP, you must first configure the vlan-type dot1q vid vlan-id-list command and specify the same value for the vlan-id-list and vlan vlan-id parameters. For more information about the vlan-type dot1q vid vlan-id-list command, see VLAN termination commands in Layer 2—LAN Switching Command Reference.

To specify the outer and inner VLAN IDs when creating a MEP, you must first configure the vlan-type dot1q vid second-dot1q command and set the same outer VLAN ID and the same inner VLAN ID in the two commands. For more information about the vlan-type dot1q vid second-dot1q command, see VLAN termination commands in Layer 2—LAN Switching Command Reference.

Predefined user roles

network-admin

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

# In an Ethernet network, 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

[Sysname] cfd service-instance 5 ma-id vlan-based md test_md vlan 100

Predefined user roles

network-admin

Parameters

default: Specifies the default rule. If no lower-level MIP exists on an interface, a MIP is created on the current level. A MIP can be created even if no MEP is configured on the interface.

explicit: Specifies the explicit rule. If no lower-level MIP exists and a lower-level MEP exists on an interface, a MIP is created at the current level. A MIP can be created only when a lower-level MEP is created on the interface.

service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.

Usage guidelines

The system automatically generates MIPs on each interface according to the rules configured.

This command takes effect only in Ethernet networks.

Examples

# Configure the MIP generation rule as default in service instance 5.

<Sysname> system-view

[Sysname] cfd mip-rule default service-instance 5

cfd service-instance

Use cfd service-instance to create a service instance.

Use undo cfd service-instance to remove a service instance.

network-admin

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.

xconnect-group group-name: Specifies the cross-connect group that the MA serves. The group-name argument is a case-sensitive string of 1 to 31 characters excluding hyphens (-).

connection connection-name: Specifies the cross-connect that the MA serves. The connection-name argument is a case-sensitive string of 1 to 20 characters excluding hyphens (-).

vsi vsi-name: Specifies the VSI that the MA serves. The vsi-name argument is a case-sensitive string of 1 to 31 characters.

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 in an Ethernet network, 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> system-view

[Sysname] cfd md test_md level 3

[Sysname] cfd service-instance 5 ma-id vlan-based md test_md vlan 100

# Create a level-4 MD named vpnmd and create service instance 10, in which the MA is identified by vpnma and serves cross-connect ac2pw in cross-connect group vpn1.

<Sysname> system-view

[Sysname] cfd md vpnmd level 4

[Sysname] cfd service-instance 10 ma-id string vpnma md vpnmd xconnect-group vpn1 connection ac2pw

Parameters

interface interface-type interface-number: Specifies an interface by its type and number. If you do not specify this option, the command displays MP information for all interfaces.

Usage guidelines

The output is arranged by interface name. On an interface, 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 interfaces.

<Sysname> display cfd mp
