FlexEdge Secure SD-WAN Manager ports
The most important default ports used in communications to and from SMC components are presented in the following illustrations.
Figure: Destination ports for basic communications within the SMC
Figure: Default destination ports for optional SMC components and features
This table lists the default ports SMC uses internally and with external components. Many of these ports can be changed. The names of corresponding default Service elements are also included for your reference.
