DSM Parameters
Device Status Message (DSM) packets and Control Status Message (CSM) packets
are an Ericsson proprietary protocol used within an nCC network to control
redundancy. These packets are IP datagrams on specific IP addresses; they are
used to provide the current health of the unit / network and to indicate whether the
unit is 'spare' or 'live'. For more information about system redundancy within nCC
please contact your system administrator.
The controls for this are:

MAC Address Configuration
This permits the overriding of the MAC addresses used by the Control Ethernet

Satellite/IP Input card (1931).
The first 3 octets of the MAC address are the Ericsson OUI, followed by 1 octet
identifying the Ericsson product, and a final pair of octets derived from the serial
number of the Motherboard.
Note: It is recommended that these settings not be adjusted unless advised to
