ONES Orchestration
This section explains how large data centers can be designed seamlessly using ONES.
Configuring Devices
Most fabric orchestration solutions available today are complex and often difficult to understand. ONES provides simple and effective tools, such as predefined templates (YAML file), to configure data centers at scale. ONES allows a customized way of configuring devices that includes enhancements to the standard configuration.
The device should not have any IP, VLAN, Portchannel, BGP, SAG, or MCLAG config on any of the Interfaces to avoid overlapping during the orchestration and run into cleanup issues.
Post that, the user needs to save the config to a file, in case of any orchestration failure, or misconfiguration user can rollback to the saved config.
Configuration Commands:
Save Config:
sudo config save -yCopy to File:
sudo cp /etc/sonic/config_db.json /host/backup_config_db.jsonRestore Config: //If needed only
sudo config reload /host/backup_config_db_json -y
Speed config for the Host Facing port should be updated before Orchestration if there is any change in the default speed config.
Ex: Interface speed is 25G, but you can use it with 10G Transceiver. In such cases, user needs to update speed.
Configuration Commands:
Update Speed:
sudo config interface speed Ethernet0 10000Configuration Commands:
Save Config:
sudo config save -yCopy to File:
sudo cp /etc/sonic/config_db.json /host/backup_config_db.jsonRestore Config: //If needed only
sudo config reload /host/backup_config_db_json -y
You need to provide the following inputs to configure the devices:
Configuration Overview
This section explains the device configuration procedures, that gets applied seamlessly across the entire fabric
Navigate to Configurations >> Devices
Click on the Configure Devices button in the top right corner. This opens a new screen with a sample device configuration. You can edit the configurations directly in the UI to make the desired changes. You can also download the sample YAML file by clicking on Download YAML button, provided at the bottom of the above screen, make new changes and upload the YAML file using Upload YAML button.

A detailed explanation of all the intend fields
Inventory: Specify how many devices you want to add in any particular role - Super Spine, Spine, Leaf, and ToR.
Inventory: SSpines: 2 #Define the count of devices in the SuperSpine role Spines: 2 #Define the count of devices in the Spine role Leafs: 2 #Define the count of devices in the Leaf role Tors: 1 #Define the count of devices in the Tor role
Connectivity: Specify the parameters required to establish link connectivity such as:
Device switch ID: unique ID for every device, required to correctly render the topology
Switch name: hostname of the device
IP address: management address of the device
Autonomous System Number (ASN): BGP AS number to use
Device Credentials: Username & Password.
MCLAG: Multichassis Link Aggregation
Links: links connected with another device
Connectivity: SSpine: [] #A role that does not have any device, presented as [] Spine: #Delcare all details, the device needs to update. - switchId: 1 #Every device we define for a given Role should have an ID that is unique to that Role. switchName: EC01 #Use the hostname of the switch ipAddress: 10.4.4.61 #Management IP address of the device to connect ASN: 1001 #BGP Local AS number Credentials: #User needs to enter device credentials user: admin password: YourPaSsWoRd mclag: #used to create multichassis link aggregation enabled: True #used to activate mclag property peer: L2 #Neighbor Device ID (Leaf Switch 2) keepalive_vlan: 10 #Vlan to use for Keepalive messages Links: #The links between all the devices we manage #SS indicates SuperSpine Role #S indicates Spine Role #L indicates Leaf Role #T indicates Tor Role #H indicates Host port #The next number is device's unique ID from the same respective Role #Then interface name and number - link: S1_Ethernet96 | L1_Ethernet96 #S1_Ethernet96 : Spine Role, Switch ID 1 with Interface Ethernet 96 is connected to #L1_Ethernet96 : Leaf Role, Switch ID 1 with Interface Ethernet 96 staticLink: True #True indicates the status is up properties: #This indicates the use of link properties mode: L2-Trunk #Used as Layer-2 Trunk vlan: 200 #Vlan used for mclag mc_po_group: 200 #Po number for mclag vrf: 1 #VRF to be used for mclag
BGP: Specify if you want to enable regular BGP peering or BGP unnumbered peering.
BGP: #BGP_U If set to False, this configures regular BGP peering. #BGP_U If set to True, this configures BGP unnumbered peering #ND_RA is reserved for future development BGP_U: False ND_RA: 30
PhysicalIfCfg: Enable or disable FEC and change the MTU settings on all the links being configured.
PhysicalIfCfg: FEC: On #Possible values are On or Off MTU: 8000 #MTU value a user wants to change AdminStatus: Up #Set the status UP
ASN: Assign a BGP ASN (Autonomous System Number) from the specified pool. Dynamic assigning ASN will be implemented in ONES release 2.0. For release 1.0, you need to specify the ASN under the device configuration, as shown in the sample YAML file.
ASN: SSpine: 10000-20000 Spine: 21000-50000 Leaf: 51000-60000 Tor: 61000-70000
IPv4Pool: Assign IP pools to different subnets. ONES automatically divides the subnets according to the number of available links.
ONES application uses IPv4 subnets for:
Interfaces
Loopbacks
Host interfaces
To configure BGP neighborship
ONES automatically advertises these subnets in BGP
IPv4Pool: Loopback: 19.168.10.0/24 LeafSpine: 20.168.10.0/24 LeafTor: 30.168.10.0/24 Host: 49.0.0.0/24
IPv6Pool: Assign IPv6 subnet.
ONES application uses:
IPv6 subnet for interfaces
Subnets to configure BGP neighborship
Automatically advertise these subnets in BGP
IPv6Pool: LeafSpine: LeafTor:
