flag

Syntax

flag { c2 | { j0 | j1 } { sdh | sonet } } flag-value

undo flag { c2 | { j0 | j1 } { sdh | sonet } }

View

RPRPOS interface view

Default 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.

Description

Use flag to set the overhead bytes of the interface.

Use undo flag to restore the default.

By default, the C2 byte value of an RPRPOS interface is 0x16, and the SDH J0 and J1 byte values are null.

NOTE:

· 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 receiving devices at network borders must use the same J0 byte. With the J0 byte, operators can detect and troubleshoot faults in advance or use less time to recover networks.

2: System level

Parameters

rprpos: Creates an RPRPOS port.

rprxge: Creates an RPRXGE port.

interface-number: Number of an RPR physical port.

Description

Use interface { rprpos | rprxge } to enter RPR physical port view.

For a switch just shipped, the interface { rprpos | rprxge } command enters only RPRPOS physical port view. To enter RPRXGE physical port view of the switch, you must execute the rpr port-type 10ge command first.

All RPR physical ports on the same subcard must be of the same type—RPRPOS or RPRXGE.

The rpr port-type command changes the RPR physical port type and takes effect only on the current subcard. If two RPR interface subcards are installed on a base card, you can set different RPR physical port types for the subcards.

If the physical port type of a subcard is RPRXGE, you can specify only the RPRXGE port type when entering RPR physical port view of the subcard; if the physical port type of the subcard is RPRPOS, you can specify only the RPRPOS port type when entering RPR physical port view of the subcard.

Examples

# Enter RPR physical port RPRPOS 2/1/1 view.

View

User view

Default level

2: System level

Parameters

rprpos: Clears statistics of RPRPOS ports.

rprxge: Clears statistics of RPRXGE ports.

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

Description

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

To collect statistics of an RPR physical port within a specific period, you need to clear statistics of the port before starting statistics collection.

If you specify none of the rprpos and rprxge keywords, this command clears the statistics of all ports.

If you specify one of the rprpos and rprxge keywords but not the interface-number argument, this command clears the statistics of all RPRPOS or RPRXGE ports.

If you specify one of the rprpos and rprxge keywords and the interface-number argument, this command clears the statistics of the specified RPRPOS or RPRXGE port.

Examples

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

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

# Clear the statistics of RPR physical port RPRXGE 3/1/1.

<Sysname> reset counters interface rprxge 3/1/1

rpr admin-request

Syntax

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

View

Layer 2 RPR logical interface view, Layer 3 RPR logical interface view

Default 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.

Description

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

By default, idle protection applies.

The following types of protection requests, Forced Switch (FS), Manual Switch (MS), and idle, are available with decreased priorities. Among them, FS and MS requests are sent manually.

· 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 request can override the MS request.

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

Examples

2: System level

Parameters

{ rprpos | rprxge } interface-number: Specifies an RPR physical port by its type and number. In RPR logical interface view, the interface-type interface-number arguments must be the type and number of an RPR physical port. In RPR physical port view, the interface-type interface-number arguments must be the type and number of an RPR logical interface.

{ rpr | rpr-bridge } interface-number: Specifies an RPR logical interface by its type and number. The value range for the interface-number argument is 0 to 15.

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.

Description

Use rpr bind to bind an RPR logical interface with an RPR physical port.

Use undo rpr bind to remove the binding.

By default, no RPR physical ports are bound with any RPR logical interface.

An RPR logical interface can be bound with two RPR physical ports, while 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 physical port is accompanied by a mate port. For an RPR 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.

Parameters

slot slot-number: Specifies the slot number of a base card installed with RPR interface subcards.

Description

Use rpr-bridge extend to configure Layer 2 RPR extension for a base card installed with RPR interface subcards. Execute this command to make sure the Layer 2 RPR function of an S9500E switch can be successfully connected to the RPR function of an S9500 switch.

Use undo rpr-bridge extend to remove the configuration.

By default, Layer 2 RPR extension is not configured for the base card installed with RPR interface subcards.

This command takes effect for only base cards installed with RPR interface subcards.

Before executing this command on a based card, make sure all cards installed on it are RPR interface subcards.

To connect the Layer 2 RPR function of an S9500E switch to the RPR function of an S9500 switch, execute the rpr station-mac command in RPR logical interface view on the S9500 switch. For more information about the rpr station-mac command, see H3C S9500 Routing Switch Series High Availability Command Reference.

After the Layer 2 RPR function of an S9500E switch is successfully connected to the RPR function of an S9500 switch, Layer 3 multicast packets are added with 4 bytes when they are inserted by the S9500E switch and copied by the S9500 switch.

ringlet1: Specifies Ringlet 1 as the default ringlet.

Description

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

Use undo rpr default-rs to restore the default.

By default, the default ringlet is Ringlet 0.

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

View

Layer 2 RPR logical interface view, Layer 3 RPR logical interface view

Default 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. The default is 5.

-r: Specifies the ringlet for the destination to send Echo Responses. 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.

Description

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

By 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.

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. In this case, 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 000F-E200-1C01, and specify ringlet 1 as the sending ringlet and ringlet 0 as the receiving ringlet on RPR logical interface RPR 1.

Default level

2: System level

Parameters

sd: Sets the signal degrade (SD) alarm threshold.

sf: Sets the signal fail (SF) alarm threshold.

value: Specifies the SD or SF threshold value in the range of 3 to 9. It is interpreted as a negative exponent of 10e. The SD alarm threshold value must be larger than the SF alarm threshold value, and the difference cannot be larger than 2.

Description

Use threshold to set the SD or SF alarm threshold for the interface.

Use undo threshold to restore the default.

By default, the SD alarm threshold is 10e-5, and the SF alarm threshold is 10e-3.

SD and SF alarms are used to indicate current line performance. The bit error rate threshold of SF is higher than that of SD. When a small amount of errors occur, SD alarms are generated; when the error rate increases to a certain level, SF alarms are generated, indicating the line performance has been degrading seriously. When setting the thresholds, set the SD threshold lower than the SF threshold.

Related commands: alarm-detect.
