  • Ports exposed on Collector Server
    Inbound Port Description
    9992 Flow syslogs from Versa devices
    50001 Versa Syslogs from Versa Analytics server
  • Collector Outbound Connections
    Address Outbound Port Description
    Versa server 8443 Versa Director API
    NMS server 443 NMS API
    NMS DNC server 9996 Flow Augmentor output
  • Ports required for K3s
    Address Outbound Port Description
    K3s supervisor & Kubernetes API Server 6443 The K3s server needs port 6443 to be accessible by all nodes
    Flannel VXLAN backend 8472 The nodes need to be able to reach other nodes over UDP port 8472 when using the Flannel VXLAN backend. However, if you do not use Flannel and provide your own custom CNI, then the ports needed by Flannel are not needed by K3s
    Kubelet Metrics 10250 All nodes must be accessible to each other on port 10250

5 Please provide the collector node IP address(es). <enter IP address(es)>
6 Does ICMP connectivity exist between the collector and the nameserver? Yes / No
7 Have you performed the health check on your SevOne NMS cluster to ensure that all critical services are up and running with no potential issues? If Yes, please share the results in the Response column.

NOTE: Execute SevOne-act check checkout --full-cluster command to perform the health check. If you do not have access to shell prompt, please contact IBM SevOne Support.

 <enter results here>
8 Have you checked the reachability of vDirector from the collector PAS?

If Yes, please share the result of curl command in the Response column.

NOTE: Please check the reachability by running the following command:

curl 'https://<vDirector-host>:9182/vnms/dashboard/navTree' -k -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'Connection: keep-alive' -u '<vdirector-username>:<vdirector-password>'

If you do not have access to shell prompt, please contact IBM SevOne Support.

 <enter output of curl command>
9 Please provide the Managed Service Provider (MSP) name for the configured vDirector.

NOTE: For MSP Name, choose an arbitrary name for this field, to logically group the devices created by the SD-WAN solution. This name will be used to create a device group containing all tenants and their sites along with the devices which are created by the collector.

 <enter details here>
10 Do you want to distribute devices created by the collector among all or some peers of the NMS cluster?

NOTE: If you want to distribute devices to some peers only then, please provide the IP addresses / peer names of those selected peers in the Response column.
