iec-mrp check-mode
Use iec-mrp check-mode to configure the detection mode for an interconnection domain.
Use undo iec-mrp check-mode to restore the default.
Syntax
iec-mrp check-mode { lc | rc }
undo iec-mrp check-mode
Default
The detection mode of an interconnection domain is Link Check mode (LC-mode).
Views
Interconnection domain view
Predefined user roles
network-admin
Parameters
lc: Configures the detection mode for the interconnection domain as LC-mode.
rc: Configures the detection mode for the interconnection domain as Ring Check mode (RC-mode).
Usage guidelines
MRP uses one of the following modes to detect link states in an interconnection domain:
· LC-mode—Each device detects the link state of its own interconnection port. The MIM determines whether to block or release its interconnection port based on the link change notification messages from MICs.
· RC-mode—The MIM determines whether to block or release its interconnection port based on whether it receives the MRP frames sent by itself.
To ensure the correct operation of MRP, configure the same detection mode for all devices in an interconnection domain.
If you execute this command multiple times, the most recent configuration takes effect.
After you enable MRP for an interconnection domain, you cannot edit the detection mode of the interconnection domain. To edit the detection mode, you must first execute the undo iec-mrp enable command to disable MRP for the interconnection domain.
Examples
# Configure the detection mode of interconnection domain 1 as RC-mode.

Predefined user roles
network-admin
Parameters
domain-inid: Specifies the InID for the interconnection domain, in the range of 1 to 65535.
Usage guidelines
Do not configure the same InID for different interconnection domains on the same device. If a device belongs to multiple interconnection domains, you must use this command to edit the InID of each interconnection domain, because the interconnection domains have the same default InID.
You can configure different domain IDs and domain names for an interconnection domain on different devices. You must configure the same InID for an interconnection domain on all devices. In a ring network, an InID is the unique identifier of an interconnection domain. InIDs are carried in MRP frames. An MRP-enabled device uses InIDs to identify interconnection domains, and chooses configuration of an interconnection domain by its InID for MRP topology calculation.
If you execute this command multiple times, the most recent configuration takes effect. After you enable MRP for an interconnection domain, you cannot edit the InID of the interconnection domain. To edit the InID, you must first execute the undo iec-mrp enable command to disable MRP for the interconnection domain.
Examples
# Configure InID 123 for interconnection domain 1.

domain-name: Specifies a domain name for the redundancy domain or interconnection domain, a case-sensitive string of 1 to 240 characters.
Usage guidelines
Use this command to configure a domain name for the redundancy domain or interconnection domain. The domain name can be used to identify the redundancy domain or interconnection domain on the device.
You cannot configure the same domain name for different redundancy domains or interconnection domains. You can configure the same domain name for a redundancy domain and an interconnection domain.
If you execute this command multiple times for the same redundancy domain or interconnection domain, the most recent configuration takes effect.
If MRP is enabled for a redundancy domain or an interconnection domain, you cannot use this command to edit the domain name. To edit the domain name, you must first execute the undo iec-mrp enable command to disable MRP for the redundancy domain or interconnection domain.
Examples
# Configure the domain name for redundancy domain 1 as ring1.
<Sysname> system

Parameters
domain-id: Specifies an interconnection domain by its domain ID. The value range for this argument is 1 to 16.
Usage guidelines
MRP uses two links to redundantly connect two MRP rings. In this way, a new ring is formed between two MRP rings. MRP uses an interconnection domain to manage the ring through four devices.
A device can belong to multiple interconnection topologies. An interconnection domain identifies an interconnection topology. In an interconnection topology, you can create multiple interconnection domains and configure different VLANs for MRP frame transmission in different interconnection domains. You can also specify different roles for a device in different interconnection domains.
The identifiers of an interconnection domain include a domain ID, a domain name, and an InID. A domain ID and a domain name identify a redundancy domain on a device. An InID is the unique identifier of a redundancy domain in a network. You can configure different domain IDs and domain names for an interconnection domain on different devices. You must configure the same InID for an interconnection domain on all devices. In a ring network, an InID is the unique identifier of an interconnection domain. InIDs are carried in MRP frames. An MRP-enabled device uses InIDs to identify interconnection domains, and chooses configuration of an interconnection domain by its InID for MRP topology calculation.

Use undo iec-mrp not-react link-change to restore the default.
Syntax
iec-mrp not-react link-change
undo iec-mrp not-react link-change
Default
The MRM processes MRP_LinkChange frames.
Views
Redundancy domain view
Predefined user roles
network-admin
Usage guidelines
Upon receiving MRP_LinkChange frames, the MRM can choose to process or not process MRP_LinkChange frames.
· If the MRM does not process the MRP_LinkChange frames, it must verify the link states in the ring network again. This can prevent the MRM from misjudging the link states in the ring network upon receiving incorrect MRP_LinkChange frames. This method takes a longer time for ring network convergence due to the repeated verifications.
· If the MRM processes the MRP_LinkChange frames, it can quickly react on link changes in the ring network. This method features shorter network convergence time but lower MRP reliability than the previous method.
After you enable MRP for a redundancy domain, you cannot edit the enabling status for the MRM to process MRP_LinkChange frames. To edit the enabling status, you must first execute the undo iec-mrp enable command to disable MRP for the redundancy domain.
Examples
# Disable the MRM of redundancy domain 1 from processing MRP_LinkChange frames.

Use undo iec-mrp priority to restore the default.
Syntax
iec-mrp priority priority-value
undo iec-mrp priority
Default
The priority value for a device in a redundancy domain is 32768.
Views

Predefined user roles
network-admin
Parameters
priority-value: Specifies the priority value for the device in the redundancy domain. The value range for this argument is 0 to 65535. The smaller the value, the higher the priority.
Usage guidelines
Use this command to configure priority values for MRAs to perform the MRM election. The MRA with a smaller priority value has higher priority. Among the devices with the same priority value, the device with a lower bridge MAC address has higher priority.
For devices configured as MRMs and MRAs, MRP can be enabled only when you configure the priority value as follows:
· For MRMs, configure the priority value as 0, 32768, or in the range of 4096 to 28672.
· For MRAs, configure the priority value as 65535 or in the range of 36864 to 61440.
You can configure this command for devices of any roles. As a best practice, do not configure this command for MRMs and MRCs, because the priority value is insignificant for them. If you specify a device as an MRA, you must manually configure a priority value for the device.
If you execute this command multiple times, the most recent configuration takes effect. After you enable MRP for a redundancy domain, you cannot edit the priority value of a device in the redundancy domain. To edit the priority value, you must first execute the undo iec-mrp enable command to disable MRP for the redundancy domain.
Examples
# Configure the priority value of the device as 40001 in redundancy domain 1.

Parameters
500ms: Sets the maximum convergence time for the redundancy domain or interconnection domain to 500 milliseconds.
Usage guidelines
After you execute this command, the MRP device adjusts its settings, such as the interval for sending MRP frames, to change the update speed of node states and port states. This eventually adjusts the maximum convergence time of the redundancy domain or interconnection domain to 500 milliseconds.
To ensure that devices in a redundancy domain or interconnection domain can detect each other, configure the same maximum convergence time for them. A smaller maximum convergence time has higher requirements for the device performance and consumes more system resources. Make sure you configure an appropriate maximum convergence time based on specific networking requirements and the performance of the devices.
If you execute this command multiple times for the same redundancy domain or interconnection domain, the most recent configuration takes effect. If MRP is enabled for a redundancy domain or an interconnection domain, you cannot use this command to edit the maximum convergence time. To edit the maximum convergence time, you must first execute the undo iec-mrp enable command to disable MRP for the redundancy domain or interconnection domain.
Examples
# Set the maximum convergence time for redundancy domain 1 to 500 milliseconds.
<Sysname> system
[Sysname] iec-mrp redundancy-domain 1
[Sysname-iec-mrp-redundancy-domain1] iec-mrp profile 500

Parameters
domain-id: Specifies a redundancy domain by its domain ID. The value range for this argument is 1 to 16.
Usage guidelines
In an MRP network, an Ethernet topology in the shape of a ring is called an MRP ring. A device can belong to multiple MRP rings. A redundancy domain identifies an MRP ring. In an MRP ring, you can create multiple redundancy domains and configure different VLANs for MRP frame transmission in different redundancy domains. You can also specify different roles for a device in different redundancy domains.
The identifiers of a redundancy domain include a domain ID, a domain name, and a domain UUID. A domain ID and a domain name identify a redundancy domain on a device. A domain UUID is the unique identifier of a redundancy domain in a network. You can configure different domain IDs and domain names for a redundancy domain on different devices. You must configure the same UUID for a redundancy domain on all devices. In a ring network, a UUID is the unique identifier of a redundancy domain. UUIDs are carried in MRP frames. An MRP-enabled device uses UUIDs to identifiy redundancy domains, and chooses configuration of a redundancy domain by its UUID for MRP topology calculation.

Parameters
auto-manager: Specifies the device as an MRA in the redundancy domain.
client: Specifies the device as an MRC in the redundancy domain or an MIC in the interconnection domain.
manager: Specifies the device as the MRM in the redundancy domain or the MIM in the interconnection domain.
Usage guidelines
An MRP device supports the following roles in a redundancy domain:
· MRM—Specify one device in the redundancy domain as the MRM to detect loops and control links.
¡ When a loop occurs in the redundancy domain, the MRM blocks one of its ring ports to eliminate the loop.
¡ When a link failure occurs in the redundancy domain, the MRM releases the ring port to restore the link.
· MRC—Specify other devices except the MRM in the MRP ring as MRCs. MRCs detect link states on their ring ports and report link changes to the MRM.
· MRA—A redundancy domain supports only one MRM. This might result in service interruption when the MRM fails. To address this issue, MRP uses MRAs to implement automatic MRM election for redundancy purposes. Upon MRP system startup, MRAs in the redundancy domain automatically elect an MRM. The remaining MRAs become MRCs. If the elected MRM becomes faulty, the MRAs that are operating correctly will automatically elect a new MRM to ensure system availability.
An MRP device supports the following roles in an interconnection domain:
· MIM—Specify one device in the interconnection domain as the MIM to detect loops and control links.
¡ When a loop occurs in the interconnection domain, the MRM blocks one of its interconnection ports to eliminate the loop.
¡ When a link failure occurs in the interconnection domain, the MRM releases the interconnection port to restore the link.
· MIC—Specify the other devices except the MIM in the MRP ring as MRCs. MICs detect link states on their interconnection ports and report link changes to the MIM.
A device's role in a redundancy domain is independent of its role in an interconnection domain.
Restrictions and guidelines
If you execute this command multiple times for the same redundancy domain or interconnection domain, the most recent configuration takes effect.
To ensure correct operation of MRP, configure only one MRM in a redundancy domain.
To ensure correct operation of MRP, configure only one MIM in an interconnection domain.
In a redundancy domain, do not configure both the MRA and MRM roles.
After you enable MRP for a redundancy domain, you cannot edit the roles of devices in the redundancy domain. To edit the roles of devices, you must first execute the undo iec-mrp enable command to disable MRP for the redundancy domain.
After you enable MRP for an interconnection domain, you cannot edit the roles of devices in the interconnection domain. To edit the roles of devices, you must first execute the undo iec-mrp enable command to disable MRP for the interconnection domain.

Parameters
vlan-id: Specifies the VLAN for MRP frame transmission in the redundancy domain or interconnection domain by its VLAN ID, in the range of 1 to 4094.
Usage guidelines
In a redundancy domain or interconnection domain, all MRP frames are transmitted within the specified VLAN.
You must configure the following settings for ports in redundancy and intercommection domains:
· Configure the ring ports in a redundancy domain to permit the VLAN for MRP frame transmission in the redundancy domain.
· Configure the interconnection ports in an interconnection domain to permit the VLAN for MRP frame transmission in the interconnection domain.
· Configure the ring ports in a redundancy domain to permit the VLANs for MRP frame transmission in the interconnection domains connected to the redundancy domain. This ensures that MRP frames can be transmitted between the redundancy domain and the interconnection domains connected to it.
If a device belongs to multiple interconnection domains or redundancy domains, you must configure different VLANs for ports in different domains to ensure the correct operation of MRP.
If you execute this command multiple times for the same redundancy domain or interconnection domain, the most recent configuration takes effect. If MRP is enabled for a redundancy domain or an interconnection domain, you cannot use this command to edit the VLAN for MRP frame transmission. To edit the VLAN for MRP frame transmission, you must first execute the undo iec-mrp enable command to disable MRP for the redundancy domain or interconnection domain.
