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
