RRPP commands
control-vlan
Use control-vlan to configure the primary control VLAN for an RRPP domain.
Use undo control-vlan to restore the default.
Syntax
control-vlan vlan-id
undo control-vlan
Default
No control VLANs exist in an RRPP domain.
Views
RRPP domain view
Predefined user roles
network-admin
Parameters
vlan-id: Specifies the primary control VLAN by its ID in the range of 2 to 4093.
Usage guidelines
When you configure control VLANs for an RRPP domain, you only need to configure the primary control VLAN. The system automatically configures the secondary control VLAN. It uses the primary control VLAN ID plus 1 as the secondary control VLAN ID. For the control VLAN configuration to succeed, make sure the IDs of the two control VLANs are consecutive and have not been assigned yet.
Do not configure the default VLAN of a port accessing an RRPP ring as the control VLAN.
A VLAN with VLAN interface resource reservation cannot be configured as the control VLAN. For more information about VLAN interface resource reservation, see Layer 2—LAN Switching Configuration Guide.
To ensure correct forwarding of RRPPDUs, do not enable QinQ or VLAN mapping on the control VLANs.
After you configure RRPP rings for an RRPP domain, you cannot delete or modify the primary control VLAN of the domain. To do so, use the undo control-vlan command.
Examples
# Configure VLAN 100 as the primary control VLAN of RRPP domain 1 (assume that VLAN 100 and VLAN 101 have not been created yet).
<Sysname> system-view
[Sysname] rrpp domain 1

domain ring
Use domain ring to configure subrings for an RRPP ring group.
Use undo domain ring to remove subrings from the RRPP ring group.
Syntax
domain domain-id ring ring-id-list
undo domain domain-id [ ring ring-id-list ]
Default
No subrings exist in an RRPP ring group.
Views
RRPP ring group view
Predefined user roles
network-admin
Parameters
domain-id: Specifies an RRPP domain by its ID in the range of 1 to 128.
ring ring-id-list: Specifies a space-separated list of up to 10 RRPP subring ID items. Each item specifies an RRPP subring ID or a range of RRPP subring IDs. The value range for RRPP subring IDs is 1 to 128. If you do not specify this option, the command removes all subrings from the ring group in the specified domain.
Usage guidelines
Follow these guidelines when you configure an RRPP ring group on the edge node and the assistant edge node:
· When you assign an active ring to a ring group, assign it on the assistant edge node first and then on the edge node.
· To remove an active ring from a ring group, remove it on the edge node first and then on the assistant edge node.
· To remove a ring group, remove it on the edge node first and then on the assistant edge node.
· When you activate rings in a ring group, activate them on the edge node first and then on the assistant edge node.
· When you deactivate rings in a ring group, deactivate them on the assistant edge node first and then on the edge node.
If you do not follow these guidelines, the assistant edge node might fail to receive Edge-Hello packets and consider the primary ring failed even if it did not.
Examples
# Create RRPP ring group 1, and add subrings 1, 2, 3, and 5 to domain 1 and domain 2.

linkup-delay-timer
Use linkup-delay-timer to set the link-up delay timer.
Use undo linkup-delay-timer to restore the default.
Syntax
linkup-delay-timer delay-time [ distribute ]
undo linkup-delay-timer
Default
The link-up delay timer is 0 seconds, and the distribute keyword is not specified.
Views
RRPP domain view
Predefined user roles
network-admin
Parameters
delay-time: Specifies the link-up delay timer in the range of 0 to 30 seconds.
distribute: Enables all nodes in the RRPP domain to learn the link-up delay timer value.
Usage guidelines
The link-up delay timer prevents frequent switchover of RRPP traffic forwarding paths caused by unstable RRPP port states.
You can configure this command on any node in an RRPP domain, but this command can take effect only on the master node.
If you specify the distribute keyword in an RRPP network implementing loading balancing, you must configure the link-up delay timer for each RRPP domain for the timer to take effect. If you set different timer values for different RRPP domains, the smallest timer value takes effect.
If the distribute keyword is not specified, the link-up delay timer value cannot be greater than the Fail timer value minus twice the Hello timer value.
Examples
# Set the link-up delay timer to 10 seconds for RRPP domain 1.
<Sysname> system-view
[Sysname] rrpp domain 1
[Sysname-rrpp-domain1] linkup-delay-timer 10

Default
No protected VLANs exist in an RRPP domain.
Views
RRPP domain view
Predefined user roles
network-admin
Parameters
reference-instance instance-id-list: Specifies the Multiple Spanning Tree Instances (MSTIs) you want to reference in the form of instance-id-list = { instance-id [ to instance-id ] }&<1-10>. The instance-id argument is an MSTI ID in the range of 0 to 4094. You can specify up to 10 MSTI IDs or ID ranges. You can use the display stp region-configuration command to display the VLAN-to-instance mappings. If you do not specify this option, the command removes all MSTIs referenced by the RRPP domain.
Usage guidelines
When the spanning tree mode of the device is PVST, the value for the instance-id-list argument can only be 0.
You can delete or modify the protected VLANs configured for an RRPP domain before and after you configure rings for the domain. However, after you configure rings for the RRPP domain, you cannot delete configurations of all the protected VLANs configured for the domain.
When the VLAN-to-instance mappings change, the protected VLANs of an RRPP domain also change.
Examples
# Map VLANs 1 through 30 to MSTI 1, and activate the MST region configuration. Configure VLAN 100 as the control VLAN of RRPP domain 1. Configure VLANs mapped to MSTI 1 as the primary control VLANs of RRPP domain 1.

Parameters
ring-id: Specifies an RRPP ring by its ID in the range of 1 to 128.
master: Specifies the device as the master node of the RRPP ring.
transit: Specifies the device as the transit node of the RRPP ring.
primary-port: Specifies the port as a primary port.
interface-type interface-number: Specifies a port by its type and number.
secondary-port: Specifies the port as a secondary port.
level level-value: Specifies an RRPP ring level, 0 for the primary ring and 1 for the subring.
assistant-edge: Specifies the device as the assistant edge node of the RRPP ring.
edge: Specifies the device as the edge node of the RRPP ring.
edge-port: Specifies the edge port for the node.
Usage guidelines
The ID of an RRPP ring in a domain must be unique.
When an RRPP ring is activated, you cannot configure its RRPP ports.
When you configure the edge node and the assistant edge node, first configure the primary ring, and then the subrings.
The node mode, RRPP port role, and ring level settings of an RRPP ring cannot be modified after they are configured. To modify the settings, first remove the current settings.
Remove all subring configurations before you delete the primary ring configuration of the edge node or the assistant edge node. However, an active RRPP ring cannot be deleted.
When RRPP is enabled on a device, you must disable the RRPP ring before you can delete it. When RRPP is disabled on the device, you can directly delete the RRPP ring, as well as the setting of the ring enable command.
Do not assign a port to both an aggregation group and an RRPP ring. If you do so, the port does not take effect on the RRPP ring.

Parameters
ring-id: Specifies an RRPP ring by its ID in the range of 1 to 128.
Usage guidelines
To activate an RRPP ring, you must enable RRPP and the RRPP ring.
Before you enable subrings on a device, you must enable the primary ring. Before you disable the primary ring on the device, you must disable all subrings. Otherwise, the system displays error prompts.
Examples
# Enable RRPP ring 10 in RRPP domain 1.

Parameters
domain-id: Specifies an RRPP domain by its ID in the range of 1 to 128.
Usage guidelines
When you delete an RRPP domain, configurations of the control VLANs and protected VLANs are deleted at the same time.
To delete an RRPP domain successfully, make sure it has no RRPP rings.
Examples
# Create RRPP domain 1, and enter RRPP domain 1 view.

Parameters
ring-group-id: Specifies an RRPP ring group ID in the range of 1 to 64.
Usage guidelines
When you remove a ring group, remove it on the edge node first and then on the assistant edge node. Otherwise, the assistant edge node might fail to receive Edge-Hello packets and consider the primary ring failed even if it is not.
After a ring group is removed, all subrings in the ring group do not belong to any ring group.
Examples
# Create RRPP ring group 1 and enter its view.
<Sysname> system-view
[Sysname] rrpp ring-group 1

snmp-agent trap enable rrpp
Use snmp-agent trap enable rrpp to enable SNMP notifications for RRPP.
Use undo snmp-agent trap enable rrpp to disable SNMP notifications for RRPP.
Syntax
snmp-agent trap enable rrpp [ major-fault | multi-master | ring-fail | ring-recover ] *
undo snmp-agent trap enable rrpp [ major-fault | multi-master | ring-fail | ring-recover ] *
Default
SNMP notifications for RRPP are disabled.

Predefined user roles
network-admin
Parameters
major-fault: Generates notifications when an SRPT between the assistant edge node and edge node is disconnected.
multi-master: Generates notifications when multiple master nodes are configured for the RRPP ring.
ring-fail: Generates notifications when the state of the RRPP ring changes from Health to Disconnect.
ring-recover: Generates notifications when the state of the RRPP ring changes from Disconnect to Health.
Usage guidelines
To report critical RRPP events to an NMS, enable SNMP notifications for RRPP. For RRPP event notifications to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see the network management and monitoring configuration guide for the device.
If you do not specify any keyword, this command enables or disables all SNMP notifications for RRPP.
Examples
# Generate notifications when the state of the RRPP ring changes from Disconnect to Health.
<Sysname> system-view
[Sysname] snmp-agent trap enable rrpp ring-recover
timer
Use timer to set the Hello timer and the Fail timer.
Use undo timer to restore the default.
Syntax
