Ping 172.16.10.1 (CDM-IP 1);
•
Ping 172.16.10.2 (CDM-IP 2);
•
Ping 172.16.10.12 (User PC 2).
•
6 From User PC 2:
Ping 172.16.10.2 (CDM-IP 2);
•
Ping 172.16.10.1 (CDM-IP 1);
•
Ping 172.16.10.11 (User PC 1).

Do not enable IF Loopback (or link the Tx to Rx by a BNC cable or satellite link) on a
CDM-IP modem operating in Managed Switch Mode when connected to a LAN. In
this configuration, Managed Switch Mode will resend all Layer 2 broadcast packets
and cause a "broadcast storm" on the LAN.
