Syntax
network-slice slice-instance-id

Default

Views
SRv6 TE policy path preference view
Predefined user roles
network-admin
Parameters
slice-instance-id: Specifies an NSI by its ID in the range of 0 to 4294967295.
Usage guidelines
You can specify an NSI ID for an SRv6 TE policy candidate path. If the path is selected, the device encapsulates an IPv6 hop-by-hop extension header that contains the NSI ID into packets forwarded through the path. The packets are called network slice packets.
If an output interface on the path contains a network slice channel that matches the NSI ID of a network slice packet, the packet is forwarded through the channel.
If no output interface on the path contains a network slice channel that matches the NSI ID of a network slice packet, the device processes the packet depending on scenarios.
· Typically, the value for the first bit (D flag) in the Flags field of the IPv6 hop-by-hop extension header is 0. The device ignores the NSI ID in the network slice packet and forwards the packet out of the output interface as a common IPv6 packet.
· In some special scenarios, for example, BFD/SBFD or ping/tracert scenarios in an SRv6 network, the value for the first bit (D flag) in the Flags field of the IPv6 hop-by-hop extension header can be set to 1. In this case, the device cannot ignore the NSI ID in the network slice packet. The packet is dropped.
Examples
# Specify NSI ID 10 for candidate path 20 of SRv6 TE policy a1.

Predefined user roles

Usage guidelines
A Layer 3 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 the current software version, only Layer 3 Ethernet interfaces, Layer 3 Ethernet subinterfaces, Layer 3 aggregate interfaces, Layer 3 aggregate subinterfaces, and FlexE interfaces support this feature.
Examples
# Enable network slicing for Ten-GigabitEthernet 3/0/1 and enter network slice view of the interface.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 3/0/1
[Sysname-Ten-GigabitEthernet3/0/1] network-slice enable

protocol-number
Use protocol-number to specify the protocol number for IPv6 hop-by-hop extension headers.
Use undo protocol-number to restore the default.
Syntax
protocol-number number

Default

Views

Predefined user roles
network-admin
Parameters
number: Specifies a number. The value takes 0 or is in the range of 160 to 252.
Usage guidelines
With SRv6 network slicing enabled, an SRv6 source node adds an IPv6 hop-by-hop extension header to a packet. The IPv6 hop-by-hop extension header contains an NSI ID. By default, the protocol number in an IPv6 hop-by-hop extension header is 0, indicating that the Next Header field of the preceding IPv6 header is 0. Upon receiving a packet, a network slicing incapable device cannot parse the IPv6 hop-by-hop extension header with protocol number 0. As a result, the packet processing becomes slow or the packet is dropped. To avoid such issues, you can use this feature to set the protocol number to a value other than 0. After that, the network slicing incapable device ignores the IPv6 hop-by-hop extension header with protocol number 0, and forwards the packet based on its IPv6 basic header. The protocol number of IPv6 hop-by-hop extension headers varies by vendor. You can edit the protocol number for interoperability between devices from different vendors.
Examples
# Specify the protocol number as 160 for IPv6 hop-by-hop extension headers.
<Sysname> system-view
[Sysname] network-slice
[Sysname-network-slice] protocol-number 160
reset network-slice statistics

network-admin
Parameters
slice-id slice-instance-id: Specifies an NSI by its ID in the range of 0 to 4294967295. If you do not specify an NSI, this command clears network slice packet statistics for all NSIs.
interface interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, this command clears network slice packet statistics for all interfaces.
Examples
# Clear network slice packet statistics for NSI 200.
<Sysname> reset network-slice statistics slice-id 200

slice-id flex-channel
Use slice-id flex-channel to create a network slice channel for an interface, and specify the bandwidth for the network slice channel.
Use undo slice-id flex-channel to remove a network slice channel from an interface.
Syntax
slice-id slice-instance-id flex-channel flex-channel-value
undo slice-id slice-instance-id flex-channel
Default
No network slice channels are configured on an interface.
Views
Network slice view of the interface
Predefined user roles
network-admin
Parameters
slice-instance-id: Specifies an NSI by its ID associated with the network slice channel, in the range of 0 to 4294967295.
flex-channel-value: Specifies the bandwidth for the network slice channel, in the range of 1 to 4294967295, in Mbps.
Usage guidelines
After you create network slice channels on the interface, the device assigns an independent scheduling queue to each network slice channel identified by an NIS ID. Packets matching an NSI ID will be forwarded through the associated channel. The protocol number of the IPv6 hop-by-hop extension headers of packets is the protocol number specified for the NSI ID associated with the channel.
The NSI specified in this command must already exist.
You can configure multiple network slice channels on an interface.
You can execute this command on an interface for multiple times. The most recent configuration takes effect.
Examples
# Enable network slicing for Ten-GigabitEthernet 3/0/1, create a network slice channel associated with NSI 10, and set the bandwidth to 50 Mbps for the channel.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 3/0/1
