If you are having system connectivity issues, here are some things to consider:
- Are there security rules on the network (such as firewalls or routers) that might be preventing this traffic?
- Is traffic from SPP routable to the network address of the managed system?
- Are there any problems with cables, hubs, or switches, and so forth?
You could be experiencing network issues like these:
- Network outage
- Router misconfiguration
- Unplugged wire
- Switch not working
