Router Mode Troubleshooting
Problem
a) Verify CDM-IP, CDD-564L Route Tables are correct.
a) Verify correct IP address/subnet on PC and CDM-IP/CDD-
56X.
b) Verify Ethernet connection – cables, hub, etc.
c) The PC, hub, and CDM-IP/CDD-564L should have Ethernet
activity LED lit.
A PC must be connected to the CDM-IP using a
hub, switch or a RJ45 crossover cable. When the
CDM-IP/CDD-56X Ethernet port senses an
Ethernet connection, the CLI displays:
Ethernet Interface UP
If the connection is broken, the CLI displays:
Ethernet Interface DOWN
b) Verify that both the hdrcomp and decomp are either enabled
or disabled.
Go to the Route Table, then Options page to
verify hdrcomp is enabled or disabled. On the
remote modem, go the main menu, press 'A'
Administration, and 'F' for Feature; hdrdecomp
should be same as hdrcomp (i.e., both should
either be enabled or disabled).
