Provides port allocation information for Cisco Catalyst SD-WAN devices configured with multiple virtual CPUs for control connections.
The Cisco SD-WAN Controllers can run on a virtual machine (VM) with up to eight virtual CPUs (vCPUs). Cisco SD-WAN Manager can be configured to a minimum of 16 vCPUs, and eight vCPUs are used for control connection ports. The vCPUs are designated as Core0 through Core7.
Each core is allocated separate base ports for control connections. The base ports differ, depending on whether the connection is over a DTLS tunnel (which uses UDP) or a TLS tunnel (which uses TCP).
Cisco SD-WAN Validators do not support multiple cores. Cisco SD-WAN Validators always use DTLS tunnels to establish control connections with other Cisco vEdge devices, so they always use UDP. The UDP port is 12346.
This table lists the port used by each vCPU core for Cisco SD-WAN Manager. Each port is incremented by the configured port offset, if offset is configured.
