Connectivity Testing and Troubleshooting
This window allows you to test a configured connection by pinging a remote host.
If the ping fails, Cisco SDM reports the probable cause and suggests actions you
can take to correct the problem.

Which connection types can be tested?

Cisco SDM can troubleshoot ADSL, G.SHDSL V1 and G.SHDSL V2
connections, using PPPoE, AAL5SNAP or AAL5MUX encapsulation.
Cisco SDM can troubleshoot Ethernet connections with PPPoE encapsulation.
