IP Module - CLI and Telnet Operation MN/CDM570L.IOM
Menu Options/Fields Entry Description
Receive 3XDES Decryption Read
Only
This feature must be purchased.
Available allows the IP M odule to decrypt packets being
received from the Satellite Interface.
When Unavailable the IP M odule cannot decrypt
packets received from the Satellite Interface. This option
is auto-sensed by a bit carried in packet headers. This
option is always available if the option is purchased.
Tx Header Compression H This option will compress headers. Headers available
for compression can be referenced in the IP Header
Compression section. Note that in easyConnect
™ mode
all Ethernet Headers will be compressed whether or not
this feature is enabled. In Router mode, this screen will
show Available, and the option must be enabled per
route in Route table.
Rx Header Compression K This option tells the system to expect received streams
to be Header compressed. Note a CDM-IP modem must
receive all streams compressed or not compressed. The
modem has no way to distinguish between compressed
or not compressed.
Tx Payload Compression C This option allows a stream of traffic to be payload
compressed. Payload is considered everything inside
the HDLC satellite frame. Therefore, IP headers could
be compressed as well. Note that in easyConnect
™
mode, the option is enabled/disabled for all traffic. In
Router mode, Payload compression will show Available,
and one must set the option Per Route in Routing table.
Rx Payload Compression Read
Only
Receive payload compression option allows a unit
receiving a stream of data that has been payload
compressed to be correctly uncompressed. This option
is auto-sensed by a bit carried in packet headers. This
option is always available if the option is purchased.
Vipersat Feature Codes F This option allows a user to enter a Vipersat features
enable code that has been provided by Comtech
Vipersat for modem configured to operate under VMS
control.
