1.1.15 rpr admin-request

Syntax

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

View

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.

Note that:

l 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.

l 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.

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

Examples

# Send an FS protection request on Ringlet 0.

1.1.16 rpr default-rs

Syntax

rpr default-rs { ringlet0 | ringlet1 }

undo rpr default-rs

View

RPR logical interface view

Default Level

2: System level

Parameters

ringlet0: Specifies Ringlet 0 as the default ringlet.

ringlet1: Specifies Ringlet 1 as the default ringlet.

Description

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

Use the undo rpr default-rs command to restore the default.

By default, the default ringlet is Ringlet 0.

Caution:

The default ringlet you configured is not necessarily the one in use. This happens when a span is faulty and unable to forward data.

Examples

# Specify Ringlet 1 as the default ringlet.

1.1.17 rpr echo mac

Syntax

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

View

RPR logical interface view

Default Level

2: System level

Parameters

mac-address: MAC address of a station in the format of H-H-H. Specify it to test the connectivity to the station.

-c value: Specifies the number of echo requests to be sent for testing connectivity, in the range 1 to 1000. If the number is not specified, five requests are to be sent.

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

If transmitting ringlet or receiving ringlet is not specified, the source station will send the Echo Request packet from the default ringlet actually taking effect. The destination station will send the Echo Response packet from the default ringlet actually taking effect.

Description

Use the rpr echo mac command to test the connectivity of the current station to the destination station. The connectivity between the current station and the destination station is considered to be normal if the connection between the two stations is normal on both the specific sending ringlet and the specific receiving ringlet. In this case, the destination station can receive the Echo Request packets that the current node sends on the specific ringlet and the current station can receive the Echo Response packets that the destination station sends on the specific ringlet. Otherwise, the connectivity between the current station and the destination station is considered to fail.

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

Examples

# Test the connectivity to the station with MAC address 0012-3F83-A1E3, specify ringlet 0 as the sending ringlet and ringlet 1 as the receiving ringlet.

Caution:

l After you change the RPR port type, the interface card will reboot to have the change take effect. The previous settings on the interface card will be lost as a result.

l This command can only take effect on 10 Gbps POS and 10GE physical ports. It cannot take effect on 2.5 Gbps POS port.

Parameters

steer: Sets the protection mode to steering where the source station directs protected frames to the ringlet that retains connectivity to their destinations.

Description

Use the rpr protect-mode command to set the RPR protection mode for the station. Use the undo rpr protect-mode command to restore the default.

By default, the steering mode applies.
