Related commands

Linktrace to target MEP 2001 with the sequence number 1101-43361.

Indicates whether the device forwards LTMs:

• Yes—The current device forwards LTMs.

• No—The current device does not forward LTMs.

Indicates whether the forwarding device found the destination MAC address in its MAC address table.

When the standard version (IEEE 802.1ag) of CFD is used:

• Hit—The current device is the destination device.

• FDB—The forwarding device found the destination MAC address.

• MPDB—The destination MAC address is not found, or the

destination MAC address is found in the MEP or MIP database.

When the IEEE 802.1ag draft5.2 version or the IEEE 802.1ag draft 5.2 interim version of CFD is used:

• Found—The forwarding device found the destination MAC address.

• Unknown—The forwarding device failed to find the destination MAC address.

• None—It is a MEP that responded to the LTM message. A MEP does not need to find the destination MAC address.

cfd linktrace auto-detection

Use cfd linktrace auto-detection to enable the auto sending of linktrace messages. Use undo cfd linktrace auto-detection to disable this function.

Syntax

cfd linktrace auto-detection [ size size-value ] undo cfd linktrace auto-detection

Default

This function is disabled.

Views

System view

Default command level

2: System level

Parameters

size size-value: Specifies the size of the buffer used to store the auto-dete ction result, in the range of

1 to 100 (in terms of sending times). This value defaults to 5, which means the buffer stores the results of the recent five auto-d etections.

Usage guidelines

After LT messages automatic sending is enabled, if the source MEP fails to receive the CCMs from the target MEP within 3.5 times the sending interval, the link between the two is regarded as faulty and L TMs will be sent out. (The destination of the LTMs is the target MEP, and the TTL field value is

255.) Based on the LTRs that echo back, the fault source can be located. Once you disable LT messages automatic sending, the content stor ed in the buffer will be removed.

Examples

# Enable automatic LT messages sending, and specify the size of the buffer used to store the auto-detection result to 100 (in terms of sending times).

You must create the relevant MD and MA prior to creating a service instance. The service instance ID uniquely identifies an MA in an MD. When deleting a service instance, you are deleting the configurations related to that service instance

as well. Deleting a service instance breaks up the connection between the service instance and the rele vant

MA, the MA itself is not deleted.

Examples

# Create a level-3 MD named test_md, create an MA named test_ma, which serves VLAN 100, in test_md, and then create service instance 5 with the MD name for test_md and test_ma.

<Sysname> system-view [Sysname] cfd md test_md level 3 [Sysname] cfd ma test_ma md test_md vlan 100 [Sysname] cfd service-instance 5 md test_md ma test_ma

cfd service-instance maid format

Use cfd service-instance maid format to create a service instance with no MD name. Use undo cfd service-instance to delete the service instance.

Syntax

cfd service-instance instance-id maid format { icc-based ma-name | string ma-name } level level-value vlan vlan-id

Parameters

service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767. icc-based ma-name: Specifies the name of an MA in Y.1731 format. The ma-name argument is a

string of 1 to 13 characters. IEEE 802.1ag standard version allows an MA name to contain letters, numbers, and special characters such as tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk(*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), backslash (\), colon (:), semicolon (;), quotation marks (", '), comma (,), period (.), and slash (/). IEEE 802.1ag draft5.2 version and IEEE

802.1ag draft5.2 interim version allow an MA name to contain letters, numbers, and special characters such as hyphen (–) and underscore (_), but do not allow an MA name to start or end with a special character.

string ma-name: Specifies the name of an MA in IEEE 802.1ag format. The ma-name argument is a string of 1 to 45 characters. IEEE 802.1ag standard version allows an MA name to contain letters,

numbers, and special characters such as tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk(*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), backslash (\), colon (:), semicolon (;), quotation marks (", '), comma (,), period (.), and slash (/). IEEE 802.1ag draft5.2 version and IEEE

level level-value: Specifies an MD level in the range of 0 to 7. vlan vlan-id: Specifies the ID of the VLAN where MA is in service, i n the range of 1 to 4094.

Usage guidelines

When you create a service instance with no MD name, the system automatically cre ates an MA and MD for the service instance.

The service instance ID, MA name, and MD level uniquely identify an MA in an MD. When deleting a service instance, you are deleting the configurations related to that service instance

as well. Deleting a service instance not only breaks up the connection between the servi ce instance a nd the

relevant MA but also deletes the MA itself. After all MAs in an MD are deleted, the MD is automatically deleted. Service instances with no MD name only apply to the IEEE 802.1ag version.

Examples

# Create service instance 5 with no MD name in the IEEE 802.1ag standard version. Create an MA named test_ma1 in Y.1731 format, with the MD level 3 and serving VLAN 100.

<Sysname> system-view [Sysname] cfd version standard [Sysname] cfd service-instance 5 maid format icc-based test_ma1 level 3 vlan 100

# Create service instance 6 with no MD name in the IEEE 802.1ag standard version. Create an MA named test_ma2 in IEEE 802.1ag format, with the MD level 4 and serving VLAN 200.

Parameters

draft5: Specifies that IEEE 802.1ag draft5.2 be used. draft5-plus: Specifies that the IEEE 802.1ag draft5.2 interim version be used. standard: Specifies that the standard version of IEEE 802.1ag be used.

Usage guidelines

If an MD is created by using the cfd md command or automatically generated by using the cfd service-instance maid format command on a device, you cannot switch between the standard

version and draft5.2 version (or draft5.2 interim version); however, you can switch between the draft5.2 version and draft5.2 interim version. This restriction does not apply to the device without an MD configured.

RPRPOS interface view

Default command level

2: System level

Parameters

c2 flag-value: Specifies the path signal label byte. It is a hexadecimal number in the range of 0x00 to

0xFF.

sdh: Sets the framing format to synchronous digital hierarchy (SDH). sonet: Sets the framing format to synchronous optical network (SONET). j0 flag-value: Specifies the regeneration section trace message. If the sdh keyword is configured,

the flag-value argument is a string of 1 to 15 characters. If the sonet keyword is configured, the argument is a hexadecimal number in the range of 0x00 to 0xFF.

j1 flag-value: Specifies the higher-Order VC-N path trace byte. If the sdh keyword is configured, the flag-value argument is a string of 1 to 15 characters. If the sonet keyword is configured, the

argument is a string of 1 to 62 characters.

Usage guidelines

Inconsistency between the c2 and j1 settings of the sending and receiving interfaces causes alarms. The J0 byte can be any character in the network of the same carrier. If networks of two carriers are

involved, however, the sending and rece iving devices at network borders must use the same J0 byte. With the J0 byte, operators can detect and troubleshoot faults in advance or use l ess time to recover networks.

Parameters

rpr: Clears statistics of the RPR logical interfaces.

interface-number: Number of the RPR logical interface. It is the number of an existing interface.

Usage guidelines

T o collect stat istics of an RPR logical interface within a specific period, you must clear statistics of the interface before starting statistics collection.

If you do not specify rpr, this command clears the statistics of all interfaces. If you specify the rpr keyword but not the interface-number argument, this command clears the

statistics of all RPR logical interfaces. If you specify the rpr keyword and the interface-number argument, this command clears the

statistics of the specified RPR logical interface.

Examples

# Clear the statistics of Layer 3 RPR logical interface RPR 1.

<Sysname> reset counters interface rpr 1

reset counters interface rprpos

Use reset counters interface to clear statistics of the specified RPR physical ports.

Parameters

rprpos: Clears statistics of RPRPOS ports.

interface-number: Specifies the number of an RPR physical port for which statistics are to be cleared.

Usage guidelines

T o coll ect statistics of an RPR physical port within a specific period, you need to clear statistics of the port before starting statistics collection.

If you do not specify the rprpos keyword, this command clears the statistics of all ports. If you specify the rprpos keyword but not the interface-number argument, this command clears the

statistics of all RPRPOS ports. If you specify the rprpos keyword and the interface-number argument, this command clears the

statistics of the specified RPRPOS port.

Examples

# Clear the statistics of RPR physical port RPRPOS 2/1/1.

<Sysname> reset counters interface rprpos 2/1/1

reset rpr protection statistics

Use reset rpr protection statistics to clear RPR protection events statistics.

Syntax

reset rpr protection statistics [ rpr interface-number ]

Views

Default command level

1: Monitor level

Parameters

rpr interface-number: Specifies an RPR logical interface by its type and number. If no RPR logical

interface is specified, the RPR protection events statistics for the RPR stations corresponding to all the RPR logical interfaces on your device are cleared.

Examples

# Clear all RPR protection events statistics.

<Sysname> reset rpr protection statistics

rpr admin-request

Use rpr admin-request to send an RPR protection request on the specified ri nglet.

Syntax

Default

Views

rpr admin-request { fs | idle | ms } { ringlet0 | ringlet1 }

Idle protection applies.

Layer 3 RPR logical interface view

Default command level

2: System level

Parameters

fs: Sends a forced switch (FS) protection request. idle: Sends an idle protection request. ms: Sends a manual switch (MS) protection request. ringlet0: Sends a protection request on Ringlet 0. ringlet1: Sends a protection request on Ringlet 1.

Usage guidelines

Six types of protection requests, FS, signal fail (SF), signal degrade (SD), MS, wait to restore (WT R), and idle, are available with decreased priorities. Among them, FS and MS requests are sent manually, whereas SF, SD, and WTR requests are sent automatically.

• Use the rpr admin-request fs command to send an FS protection request. As the FS request takes priority over all other requests, you can remove it from the RPR ring only with the rpr admin-request idle command.

• Use the rpr admin-request ms command to send an MS protection request. As the priority of the MS request is the lowest, RPR ring does not perform MS switching if any other type of protection request is present. On the contrary, the FS, SF, or SD reque st can override the MS request.

• Use the rpr admin-request idle command to clear the FS or MS protection request.

Examples

# Configure Layer 3 RPR logical interface RPR 1 to send an FS protection request on Ri nglet 0.

<Sysname> system-view [Sysname] interface rpr 1 [Sysname-RPR1] rpr admin-request fs ringlet0

rpr bind

Use rpr bind to bind an RPR logical interface with an RPR physical port. Use undo rpr bind to remove the binding.

Syntax

In Layer 3 RPR logical interface view:

rpr bind rprpos interface-number { ringlet0 | ringlet1 } undo rpr bind rprpos interface-number

In RPRPOS interface view:

rpr bind rpr interface-number { ringlet0 | ringlet1 } undo rpr bind

Default

No RPR physical ports are bound with any RPR logical interface.

Views

Default command level

2: System level

Parameters

rprpos interface-number: Specifies an RPR physical port by its type and number. rpr interface-number: Specifies an RPR logical interface by its type and number. ringlet0: Uses the RPR physical port that receives data frames on Ringlet 0 and sends data frames

on Ringlet 1 as the west port of the current or specified RPR logical interface. ringlet1: Uses the RPR physical port that sends data frames on Ringlet 0 and receives data frames

on Ringlet 1 as the east port of the current or specified RPR logical interface.

Usage guidelines

An RPR logical interface can be bound with two RPR physical ports, and an RPR physical port can be bound with only one RPR logical interface.

For an RPR station to operate correctly, an RPR logical interface must be bound with at least one RPR physical port.

Each RPR physical port is accompanied by a mate port. For an RP R station to operate correctly, you must use optical fibers to connect the mate ports of the two RPR physical ports bound with its corresponding RPR logical interface.

Examples

# Configure RPR physical port RPRPOS 2/1/1 as the west port of Layer 3 RPR logical interface RPR

<Sysname> system-view [sysname] interface rpr 1 [sysname-RPR1] rpr bind rprpos 2/1/1 ringlet0

# Configure Layer 3 RPR logical interface RPR 1 as the east port of RPR physical port RPRPOS 2/1/2.

<Sysname> system-view [sysname] interface rprpos 2/1/2 [sysname-RPRPOS2/1/2] rpr bind rpr 1 ringlet1

rpr default-rs

Use rpr default-rs to configure the default RPR ringlet for sending data frames. Use undo rpr default-rs to restore the default.

Syntax

rpr default-rs { ringlet0 | ringlet1 } undo rpr default-rs

Default

The default ringlet is Ringlet 0.

Views

Default command level

2: System level

Parameters

ringlet0: Specifies Ringlet 0 as the default ringlet. ringlet1: Specifies Ringlet 1 as the default ringlet.

Usage guidelines

In case the default ringlet you configured is faulty, the other ringlet works as the default ringlet to forward data.

Examples

# Specify Ringlet 1 as the default ringlet on Layer 3 RPR logical interface RPR 1.

<Sysname> system-view [Sysname] interface rpr 1 [Sysname-RPR1] rpr default-rs ringlet1

rpr echo mac

Use rpr echo mac to test the connectivity between the current station and a peer station.

Syntax

rpr echo mac mac-address [ -c c-value | -r { ringlet0 | ringlet1 | reverse } | -s { ringlet0 | ringlet1 } | -t t-value ] *

Default

Five Echo Request packets are sent. It is the default ringlet in use that sends Echo Response packets and Echo Request packets. The response timeout time is 10 milliseconds.

Views

Layer 3 RPR logical interface view

Default command level

2: System level

Parameters

mac-address: Tests the connectivity to the station identified by the MAC address.

-c c-value: Specifies the number of Echo Requests to be sent for testing connectivity, in the range of

1 to 1000.

-r: Specifies the ringlet for the destination to send Echo Respo nses. It could be ringlet0, ringlet1, or

reverse. If the reverse keyword is specified, the destination station is expected to send Echo

Reponses from the ringlet different from the one from which it receives Echo Requests. For example, if the destination station receives Echo Requests from Ringlet 0, it should send out Echo Responses onto Ringlet 1.

-s: Specifies the ringlet for sending Echo Requests, either ringlet0 or ringlet1.

-t t-value: Specifies the echo response timeout in the range of 10 to 65535 milliseconds. If it is not

specified, the default of 10 milliseconds applies.

Usage guidelines

If neither the sending ringlet nor the receiving ringlet is specified, the default ringlet in use will be used for transmitting Echo Request packets and Echo Response packets.

The connectivity between the current station and a peer station is considered normal only when the connections between the two stations operate correctly on both the sending ringlet and the receiving ringlet. The peer station can receive Echo Request packets from the current node on a specific ringlet and the current station can receive Echo Response packets from the peer station on a specific ringlet. Otherwise, the connections between the current station and the peer station are considered faulty.

Examples

# Test the connectivity between the current station and the station with MAC address 0012-3F83-A1E3, and specify ringlet 0 as the sending ringlet and rin glet 1 as the receiving ringlet on Layer 3 RPR logical interface RPR 1.
