The CDM-IP will also be in Point-to Point HDLC Addressing Mode. HDLC addresses
are used to identify remote satellite interfaces when there are more than two CDM-IP
modems sending and receiving traffic. In Point-to-Point Mode, there is no need to define
any HDLC addresses since all of the traffic will be to and from a single remote CDM-IP.
1.2.3 S ETTING IP A DDRESS ( ES )
Step Description
1 From the Main Menu select Interface Configuration sub-menu [I].
2 From the Interface Configuration Menu select Ethernet Interface (fei0) sub-menu [E].
3 Set IP Address [I].
CDM-IP 1 to 172.16.10.1
CDM-IP 2 to 172.16.10.2
4 Set Subnet Prefix Length [M] to 24
The other parameters can be left to their factory default settings.
At this point the basic configuration is over and you should be able to:
5 From PC1
Ping 172.16.10.1 (CDM-IP 1)
Ping 172.16.10.2 (CDM-IP 2)
Ping 172.16.10.12 (PC 2)
6 From PC2
Ping 172.16.10.2 (CDM-IP 2)
Ping 172.16.10.1 (CDM-IP 1)
Ping 172.16.10.11 (PC 1)
IMPORTANT
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 EasyConnect
 when connected to a LAN. In this
configuration, EasyConnect
 will resend all layer 2 broadcast packets and cause a
“broadcast storm” on the LAN. To perform a loop test to verify the modem or satellite
link, do one of the following:
(CDM-IP 550 Only) Reconfigure the CDM-IP 550 to CDM 550 Emulation Mode by
selecting Configuration/Interface and then selecting EIA-422/530, V.35, or EIA-232.
Set the CDM-IP modem to Router Mode.
