4.1.6 Event Logging to Capture All Demodulator Activity
All activity can be stored into an easy-to-read Event Log. This file also can be retrieved locally or
remotely by FTP.
4.1.7 Detailed Statistics of IP Traffic
IP traffic statistics are continuously updated and allow detailed performance analysis or can be used to
identify traffic problems. The statistics are available through the Serial Console locally, or can be
gathered remotely by SNMP, Telnet, or HTTP.
4.1.8 IGMP Support for Multicast
IGMP is a standard feature in the demodulator. If enabled as an IGMP client, it responds to IGMP queries
for the configured multicast routes. If enabled as an IGMP server, it generates IGMP queries and
transmits multicast traffic per IGMP clients’ request. If there are no active IGMP clients on the LAN, it
will stop forwarding the multicast traffic (received from the satellite) to the LAN.
4.1.9 Static IP Routing for Unicast and Multicast
Up to 256 static routes can be entered into the demodulator to direct IP traffic to another device on the
local LAN.
4.2 Demodulator Features
See Chapter 6, Fast Activation Procedure.
Additional features can be added quickly on site to the CDD-56xA/L by entering FAST Access Codes
purchased from Comtech EF Data. FAST-accessible options include:
•
IP Header Decompression
•
Payload Decompression (future)
4.2.1 3xDES Decryption with Ability to Change Keys (future)
The EN version supports 3xDES-128 (using NIST certified 3x core) decryption for the highest-level
security. For link encryption, each unit supports eight decryption keys.
4.2.2 IP Header Decompression
Header Decompression also is an optional feature of the demodulator. The demodulator supports Header
Decompression for the following Ethernet and Layer 3 & 4 Headers:
