replace dscp dscp-value: Replaces the DSCP value in matching packets with the specified value.
Usage guidelines
Operating mechanism
With this feature configured, the device binds the specified packets to NSI IDs. When forwarding the packets through an output interface, the device searches for the network slice channel configured on the output interface. The device then schedules and forwards the packets through the network slice channel identified by the bound NSI ID. If no network slice channel identified by the bound NSI ID exists on the output interface, the device forwards the packets according to routing table lookup.
You can repeatedly execute the index binding-type command to configure multiple bindings between packets and NSI IDs identified by different index-value values. Upon receiving a packet, the system compares it with packet match criteria in ascending order of index values specified with the index binding-type command. If a match is found, the system does not continue to compare the packet with other bindings.
Restrictions and guidelines
If you repeatedly execute the index binding-type command and specify the same index value, the most recent configuration takes effect.
If you bind a DSCP/VLAN/VXLAN value or interface/VSI to an NSI ID, you cannot bind the DSCP/VLAN/VXLAN value or interface/VSI to any other NSI IDs.
In the current software version, only Layer 2 Ethernet interfaces, Layer 2 aggregate interfaces, and Layer 3 Ethernet interfaces support scheduling and forwarding the packets through the network slice channel identified by the bound NSI ID.
Examples
# Configure two bindings between packets and NSI IDs:
· Binding 1: Binds packets carrying DSCP values 10 through 20 to NSI ID 10. The device schedules and forwards matching packets through the network slice channel identified by NSI ID 10.
· Binding 2: Binds packets carrying VLANs 10 through 20 to NSI ID 20. The device schedules and forwards matching packets through the network slice channel identified by NSI ID 20, and replaces the DSCP values in the packets with 63.

Usage guidelines
An output interface with network slicing enabled forwards packets carrying an NSI ID through a network slice channel (matching the NSI ID) on the interface. In different network slicing scenarios, you can execute this command to enable network slicing on the interface, but the mechanisms and interface types used for network slicing vary by scenario. For example, in the SRv6 network slicing scenario, packets will be encapsulated with and carry the NSI ID information. Typically, network slicing is enabled for Layer 3 Ethernet interfaces or FlexE logical interfaces. In the campus network slicing scenario, an NSI ID is bound to packets and is not carried in the packets. In this case, network slicing can be enabled on Layer 2 Ethernet aggregate interfaces.
If you configure the network-slice enable command to enable network slicing for the interface, you cannot add the interface to a link aggregate group.
This command is supported only on physical interfaces and Layer 2 aggregate interfaces. In the current software version, this command is not supported by Layer 3 aggregate interfaces and their member ports (including the associated Layer 3 aggregate subinterfaces).

Parameters
number: Specifies a queue buffer class by its number for a network slice channel. The value range for this argument is 0 to 10. The greater the number, the larger the available buffer space.
Usage guidelines
Operating mechanism
The queue buffer size on the output interface is fixed. The higher the queue buffer class, the larger the buffer space available for packets in the network slice channel. If network congestion occurs on the output interface, packets are less likely to be discarded when a larger buffer space is available.
Restrictions and guidelines
For applications that are sensitive to packet loss, you can set a larger queue buffer class to reduce the packet loss probability.
As a best practice, do not manually adjust this parameter setting.
Examples
# Configure the queue buffer class as 3 for a network slice channel.

[Sysname] network-slice
[Sysname-network-slice] instance 1

Usage guidelines
This command takes effect only on SF series interface modules. As a best practice when you configure this feature, make sure all interface modules on the device are the SF series. If other series of interface modules exist, use queue-mode network slicing.
Only default MDCs support this command.
This feature allows for further classification of service packets within a network slice channel. It first performs queue scheduling based on service granularity and then performs queue scheduling based on the same network slice channel.
After you configure the queue group mode for network slice channels, each network slice channel corresponds to one queue on an interface. Each queue group contains eight queues. For the first scheduling, different types of service packets are mapped to different network slice channels based on the bindings between packets and NSI IDs configured with the index binding-type command. Then, a secondary scheduling is performed, which maps the packets to different queues within the network slice channels based on the packets' local priorities, achieving hierarchical scheduling management.
You cannot directly switch the network slice channel from queue mode to queue group mode by using this command. To do that, enable the network slicing feature again, execute this command, and then restart the device for the queue group mode to take effect.

# Configure the queue group mode for network slice channels.

Parameters
slice-instance-id: Specifies an NSI by its ID associated with the network slice channel. In queue mode, the value range for the slice-instance-id argument is 0 to 6. In queue group mode, the value range for the slice-instance-id argument is 0 to 1023. If you configure the value as 0, the configuration does not take effect.
flex-channel bandwidth-value: Specifies the bandwidth for the network slice channel, in the range of 1 to 4294967295, in Mbps. Make sure the value does not exceed the actual interface rate.
shared: Specifies the shared mode. In this mode, network slice packets with different network slice channel IDs can share the bandwidth of this network slice channel. If you do not specify this keyword, the network slice channel is in exclusive mode. In exclusive mode, only network slice packets with the specified network slice channel ID can be forwarded through this network slice channel.
Usage guidelines
Operating mechanism
The device allocates independent scheduling queue resources for network slice channels on the interface. Packets matching an NSI ID are forwarded through the associated network slice channel. The bandwidth specified for the network slice channel created on the interface serves as both the guaranteed bandwidth and the upper limit for the channel. Traffic exceeding this bandwidth is processed by traffic shaping for buffering.
Use this command to create network slice channels on interfaces. The device supports the following types of network slice channels:
· Network slice channels in exclusive mode—When you configure a network slice channel on an interface, specify the flex-channel keyword without the shared keyword. The device will allocate exclusive-mode scheduling queue resources to this network slice channel. Network slice packets from other network slice channels and non-network slice packets cannot preempt the scheduling queue resources of this network slice channel.
· Network slice channels in shared mode—When you configure a network slice channel on an interface, specify the flex-channel keyword with the shared keyword. The device will assign shared-mode scheduling queue resources to this network slice channel. Non-network slice packets and network slice packets from other network slice channels can compete for the scheduling queue resources of this network slice channel during network congestion. Network slice channels in shared mode enable more flexible traffic scheduling.
Restrictions and guidelines
The NSI ID specified in this command must already be created with the instance command.
You can configure multiple network slice channels for an interface.
When the network slice channels are in queue group mode, first configure the binding between packets and NSI IDs. Then, execute this command on the interface to specify the bandwidth for network slice channels. If you do not perform the configuration in this way, the network slice channels might not take effect correctly.
When the network slice channels are in queue mode, the network slice channel bandwidth configuration is mutually exclusive with the queue-based traffic shaping configuration and interface WFQ queue configuration. For more information about queue-based traffic shaping and interface WFQ configuration, see QoS configuration in ACL and QoS Configuration Guide.
Examples
# Binding interface Ten-GigabitEthernet3/0/1 to NSI ID 10, create a network slice channel, and set the bandwidth to 50 Mbps for the network slice channel.
<Sysname> system-view

Parameters
priority-number: Specifies a scheduling priority. The value range for this argument is 0 to 3. The greater the value, the higher the priority.
Usage guidelines
This command is supported only in queue group mode.
After you configure the queue-group mode enable command, you can use the slice-priority command in queue group mode to configure scheduling priorities for different network slice channels. Network slice channels with the same scheduling priority are scheduled in a round-robin manner. If the queue-group mode enable command is not configured, each network slice channel represents a queue in queue mode. Different network slice channels are scheduled with strict priority. The higher the NSI ID, the higher the scheduling priority.
When multiple network slice channels exist on the output interface, the device performs strict priority-based scheduling according to the scheduling priority of the network slice channels. If network congestion occurs on the output interface, packets in higher-priority network slice channels are forwarded first. Packets in lower-priority network slice channels can be scheduled in sequence only after all packets from the high-priority network slice channels are forwarded out of the queue.
Examples
# Set the scheduling priority to 3 for a network slice channel.

[Sysname] network-slice
[Sysname-network-slice] instance 1
[Sysname-network-slice-instance-1] slice-priority 3
statistics enable
Use statistics enable to enable network slice packet statistics.
Use undo statistics enable to disable network slice packet statistics.

Usage guidelines
With network slice packet statistics enabled, you can use the display network-slice statistics command to display statistics of packets forwarded through the specified network slice.
After you create a mapping rule by executing the index binding-type command in NSI-to-packet mapping view, packets can be assigned to the configured slice. At this point, you must execute the slice-id flex-channel command for the interface to configure the network slice channel for the interface, so that packets can be counted for the corresponding network slice channel. Without the configuration, no slice channel is configured, and the network slice traffic data cannot be collected.

Application scenarios
You can enable this feature on VTEPs and non-VTEPs in a VXLAN network to carry different service packets through network slices and achieve differentiated scheduling for various services.
Operating mechanism
· Enable this feature on a VTEP:
When the VTEP receives the original packet, it first matches the packet's characteristics with the bindings configured with the index binding-type command to associate the original packet with the NSI ID. Then, it encapsulates the packet with a VXLAN header. During VXLAN packet encapsulation, the VTEP uses the higher 20 bits of the Reserved field in the VXLAN header to carry the NSI ID. On the output interface, the device schedules and forwards the packet based on the NSI ID through the associated network slice channel.
· Enable this feature on a non-VTEP in a VXLAN network:
The non-VTEP can read the NSI ID from the VXLAN header in a received packet. On the output interface, the device schedules and forwards the packet based on the NSI ID through the associated network slice channel.
Restrictions and guidelines
If you configure both the index binding-type and vxlan reserved enable commands on a non-VTEP in a VXLAN network, the device first compares the packet with the bindings configured with the index binding-type command.
· If a matching NSI ID is found, the device schedules the packet on the output interface based on the NSI ID.
· If no matching NSI ID is found, the device reads the NSI ID from the VXLAN header of the packet, and then schedules the packet on the output interface based on the NSI ID.
If the index binding-type command is not configured on the non-VTEP in a VXLAN network, you can use this feature as a supplementary measure to obtain the NSI ID from packets.
For the same VXLAN packet, all devices in the VXLAN network will obtain the same NSI ID for configuring unified scheduling mechanism.
