IP Redundancy Configuration

Setup of a CDM‐570L 1:1 IP Redundancy System, using the CLI, is as follows:
Step Procedure
1 The two modems will need an Ethernet connection to each other through a Layer 2 switch
(preferred) or hub.
2 Before connecting the modems to the CRS-170A, you will need to first configure the following
modem IP module settings:
•
•
•
3 On both modems, enter a unique IP Address that is on the same subnet (Interface
Configuration
modem to the other (Operations and Maintenance
4 On both modems, set Redundancy Configuration
Parameters to permanent storage and power down both modems.
5 Connect the modems to the CRS-170A.
6 While monitoring the Serial console CLI on both modems, observe the following after powering
on both modems at the same time (also observe the CRS-170A Online LEDs to see which
modem is the Online modem).
Online modem CLI displays:
Offline modem CLI displays:
7 On the Online modem, select the Redundancy Configuration menu (Figure 3-3). Observe that
the correct IP Address/Mask is displayed for the Local and Redundant Unit. You will then need to
set the Traffic IP Address/Mask (this also needs to be in the same subnet as the Management IP
addresses).
Redundancy Configuration
Administration Working Mode: Both modems need to be set to the same
Working Mode.
Administration Features: Both modems need to have the same IP Option
Feature set.
