CDD-562L/564 Demodulator with IP Module Revision 1
Ethernet Management MN/CDD564L.IOM
7–4
The user defines three Community Strings for SNMP access:
• Read Community default = public
• Write Community default = private
• Trap Community default = comtech
Note: Maximum number of characters for community strings shall not exceed 20. All printable ASCII
characters, except ’\’ and ‘~’ are allowed. No trailing spaces are permitted for community strings.
7.4.3 SNMP Traps
The demodulator has the ability to send out SNMP traps when certain events occur in the unit.
For example, when the demodulator boots it sends out a coldstart trap and a linkup trap for each
interface that is brought up. The demodulator also sends out traps when an alarm or a fault occurs
in the unit. These include Unit faults, Rx faults, and LNB faults. A trap is sent both when a fault
occurs and is cleared.
The demodulator supports both SNMPv1 traps and SNMPv2 notifications. Which style of traps the
CDM-570/570L sends can be configured by the user using the cdd564SNMPTrapVersion OID.
The following are the MIB-II v1traps/v2 notifications that the modem supports:
MIB-II SNMPv1 traps:
Cold Start 1
Link Up 4
Authentication Failure 5
MIB-II SNMPv2 notifications:
Cold Start 1.3.6.1.6.3.1.1.5.1
Link Up 1.3.6.1.6.3.1.1.5.4
Authentication Failure 1.3.6.1.6.3.1.1.5.5
The following tables are the Alarms and Faults v1 traps / v2 notifications that the modem supports.
