CDM-570/570L Satellite Modem with Optional IP Module
IP Module CLI and Telnet Operation
DES key select <Choose [1-8] for [key1-key8] 0=Clear 9=Random Enter= Clear>:
The value of 0 [CLEAR] will force the IP Module to not encrypt any traffic destined for
the route.
The value of Key[1-8] will use the key specified in the 3xDES Encrypt/Decrypt
Configuration Page to encrypt the traffic destined for the route.
The value of Random will cause the IP Module to randomly use any of the 8 TX Keys to
encrypt the traffic destined for the route.
3xDES Encryption:
IMPORTANT
easyConnect Mode – By definition, there are no routes in easyConnect
operation, so there is no way to assign different keys to traffic. When TX 3xDES
encryption is enabled in easyConnect, all traffic (IP and non-IP) is encrypted and
TX Key1 is always used.
Router Mode – Different TX keys can be assigned to different routes and some
routes can be sent unencrypted [Clear]. If Random is selected, then all TX Keys
must be configured with different keys and the receiving IP modem must have
identical corresponding RX Keys. The IP Module will randomly utilize all 8 Keys for
encryption.
