flag

Syntax

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

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

View

RPR POS 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 the flag command to set the overhead bytes of the interface.

Use the undo flag command to restore the default.

By default, the C2 byte value of an RPR POS 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.

rpr admin-request

Syntax

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

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

By default, idle protection applies.

Six types of protection requests, FS, signal fail (SF), signal degrade (SD), MS, wait to restore (WTR), 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 request 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 Ringlet 0.

Default level

2: System level

Parameters

{ rprpos | rprxge } 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.

Description

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

Use the undo rpr bind command 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, and an RPR physical port can be bound with only one RPR logical interface.

For an RPR station to operate properly, 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 RPR station to operate properly, 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 2/1/2 as the west port of Layer 3 RPR logical interface RPR 1.

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 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 10 to 65535 milliseconds. If it is not specified, the default of 10 milliseconds applies.

Description

Use the rpr echo mac command 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 properly 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 ringlet 1 as the receiving ringlet on Layer 3 RPR logical interface RPR 1.

threshold

Syntax

threshold { sd | sf } value

undo threshold { sd | sf }

View

RPR POS interface view

Default level

2: System level

Parameters

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

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

value: 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 the threshold command to set the SD or SF alarm threshold for the interface.

Use the undo threshold command 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. They are generated when the receiving end detects a certain amount of B2 errors. 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.

Examples

# Set the SD threshold on RPRPOS2/1/1 to 10e-5.

<Sysname> system-view

[Sysname] interface rprpos 2/1/1

[Sysname-RPRPOS2/1/1] threshold sd 5
