Parameters
flow-id: Specifies a flow ID in the range of 1 to 16000.
destination-ip ipv4-address: Specifies a destination IPv4 address for packets.
mask mask: Specifies a mask length for the destination IPv4 address, in the range of 1 to 32.
destination- ipv6 ipv6-address: Specifies a destination IPv6 address for packets.
prefix prefix-length: Specifies a prefix length for the destination IPv6 address, in the range of 1 to 128.
destination-port port-number: Specifies a destination port number in the range of 0 to 65535.
dscp dscp-value: Specifies a DSCP value for the packets in the range of 0 to 63.
protocol protocol-value: Specifies a protocol by its type value in the range of 0 to 255.
source-ip ipv4-address: Specifies a source IPv4 address for packets.
source-ipv6 ipv6-address: Specifies a source IPv6 address for packets.
source-port port-number: Specifies a source port number for packets, in the range of 0 to 65535.
Usage guidelines
Operating mechanism
Use this command to configure parameters for a DetNet flow, including the flow ID, source address, destination address, source port, destination port, protocol type, and DSCP value. If you do not configure a parameter for the DetNet flow, the device does not use that characteristic to filter the flow entering the corresponding DetNet path.
Configure this command only on the ingress edge node of a DetNet path.
Restrictions and guidelines
If you execute this command multiple times for a DetNet flow, the most recent configuration takes effect.
If a DetNet path has been applied to a DetNet flow by the apply flow command, you cannot edit or delete the DetNet flow. To edit or delete the DetNet flow, first use the undo apply flow command in the view of the corresponding DetNet path to delete the applying relationship.
Examples
# Create a DetNet flow and configure the flow ID as 10, the destination IPv6 address as AD80::ABAA:0000:00C2:0002, and the IPv6 prefix length as 112.
<Sysname> system-view

Parameters
Color-value:: Specifies a Color value for an SRv6 path policy, in the range of 0 to 4294967295.
ipv6 ipv6-address: Specifies a destination endpoint by its IPv6 address for an SRv6 path policy.
Usage guidelines
Operating mechanism
After you configure the path policy attributes for a DetNet path, if the corresponding SRv6 TE policy exists on the current node, the DetNet path will automatically take effect for packet forwarding. The specified Color value is the Color attribute for the forwarding path, which is used to distinguish an SRv6 DetNet path from other SRv6 DetNet paths that are configured for the same source and destination endpoints. The specified destination endpoint IPv6 address is the IPv6 address of the destination endpoint for the SRv6 DetNet path.
Restrictions and guidelines
Configure this command only on the ingress edge node of a DetNet path.
If you execute this command multiple times, the most recent configuration takes effect.
You cannot configure the same policy attributes for different DetNet paths.
Examples
# Configure the Color value as 20 and the destination endpiont IPv6 address as 1000::1 for SRv6 DetNet path 10.
<Sysname> system-view
[Sysname] detnetip path 10

Parameters
interface-type interface-number: Specifies an interface by its type and number. Currently, only Layer 3 Ethernet interfaces and Layer 3 Ethernet sub-interfaces are supported as the source interfaces for DetNet paths.
Usage guidelines
Use this command to specify a source interface for packets to enter a DetNet path. If the source interface is not specified, the path will not take effect.
Configure this command only on the ingress edge node of a DetNet path.
Make sure the specified source interface has DetNet capability. You can use the display detnetip capability command to view DetNet capability information about an interface.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
Configure the source interface for DetNet path 10 as Ten-GigabitEthernet3/1/1.
<Sysname> system-view
[Sysname] detnetip path 10

timeslot
Use timeslot to configure a forwarding timeslot for a node on a DetNet path.
Use undo timeslot to delete the forwarding timeslot configuration for the specified node or all nodes.
Syntax
timeslot hop hop-index value value
undo timeslot [ hop hop-index ]
Default
The forwarding timeslot is not configured for a node on a DetNet path.
Views
DetNet path view
Predefined user roles
network-admin
Parameters
hop hop-index: Specifies a node by its index in the range of 1 to 11. The index for the ingress edge node on a DetNet path is 1, and the index of each subsequent node is increased by 1 in the packet forwarding order.
value value: Specifies a queue by its queue number for the outgoing interface of the node, in the range of 1 to 15.
Usage guidelines
Operating mechanism
Use this command to specify a queue for the outgoing interface on each node of a DetNet path. After the configuration, each node will forward the incoming packets through its outgoing interface in the timeslot for the corresponding queue.
In most cases, the SDN controller performs parameter detection and latency deviation calculation for a DetNet path, and then automatically deploys the forwarding timeslot configuration to the ingress edge node of the path. Manual configuration through the CLI is usually used for debugging.
Restrictions and guidelines
You must configure the forwarding timeslot for each node in the forwarding order of a path, which starts from the ingress edge node and ends at the egress edge node.
To add transit nodes, perform one of the following tasks:
· Delete the forwarding timeslot configuration for all existing nodes after the new nodes, and then configure a forwarding timeslot for each node starting from the new node closest to the ingress edge node.
· Execute the undo timeslot command to delete the forwarding timeslot configuration for all nodes on the path, and then configure a forwarding timeslot for each node in the planned forwarding order.
If you execute this command multiple times for a node, the most recent configuration takes effect.
When using the undo timeslot hop hop-index command to delete the forwarding timeslot configuration for a node, make sure the node is the last node with forwarding timeslot configuration on a path.
Examples
# On DetNet path 10, specify queue 5 for the outgoing interface on the ingress edge node whose index is 1, queue 8 for the outgoing interface on node 2 and queue 10 for the outgoing interface on the egress edge node whose index is 3.
<Sysname> system-view
[Sysname] detnetip path 10
[Sysname-detnet-path10] timeslot hop 1 value 5
[Sysname-detnet-path10] timeslot hop 2 value 8
[Sysname-detnet-path10] timeslot hop 3 value 10
