VeloCloud is a cloud network service solution enabling sites to deploy Enterprise grade access to legacy and cloud applications over both private networks and Internet broadband.
The following diagram shows the VeloCloud Software-defined WAN solution (SDWAN) components (in orange).
Basic VeloCloud discovery
- Provides end-to-end visibility into VeloCloud based SDWAN infrastructure.
- Associates core MPLS network components and the VeloCloud overlay tunnels.
The Server Manager imports initial topology from the IP Availability Manager. After the topology is imported, Server Manager discovers domain-specific entities related to the features and creates additional topology objects for those features.
The discovery time for a VeloCloud topology is proportion to the number of edges in the VeloCloud.
For, the VeloClouds with the large number of Edges the discovery takes hours. If the configuration is changed at a Tenant/Edge level, then to get just the new changes the incremental discovery can be used. There incremental discovery can be triggered for an existing Tenant/Edge.
The rediscovery can only be triggered using a remote API client or dmctl command of the Server Manager.
Incremental Tenant Discovery
To trigger an incremental tenant discovery,, run the following command:
dmctl -s <esm server> invoke Tenant::<TenantName> rediscover
Where, TenantName is the name of the tenant in the ESM topology for which the incremental discovery must be triggered.
Incremental Edge Discovery
To trigger an incremental edge discovery, run the following command:
dmctl -s <esm server> invoke VEdge::<EdgeName> rediscover
Where, EdgeName is the name of the VEdge instance in the ESM topology for which the incremental discovery must be triggered.
The incremental tenant discovery discovers IP, interfaces, and network connection for the Edge. It does not discovery relationships that are between edges (Hub and Spoke, Edge Cluster) and edge and Gateways(Tunnel).
For first time when discovery is initiated from SMARTS Domain Manager, DCF controller (part of the DCF framework) managing the lifecycle of the collectors instantiates and deploys the VeloCloud Discovery and Monitoring Collectors. The polling configuration applied to the VeloCloud Monitoring Collector polls VeloCloud Orchestrator based on specified polling cycle and frequency. The monitoring collector polls for the status attribute of the discovered Velocloud topology objects.
