Ethernet Management MN/CDM710.IOM
6–4
6.3.1.6 HSSI MIB
SNMP for the HSSI interface is not supported at this time.
6.3.2 SNMP Community Strings
The CDM-710 uses community strings as a password scheme that provides authentication before
gaining access to the modem agent’s MIBs.
In “SNMP v1/v2c”, the community string is sent unencrypted in the SNMP packets. Caution
must be taken by the network administrator to ensure that SNMP packets travel only over a
secure and private network if security is a concern. A packet sniffer can easily obtain the
community string by viewing the SNMP traffic on the network.
The community string is entered into the MIB Browser or Network Node Management software
and is used to authenticate users and determine access privileges to the SNMP agent.
The user defines three Community Strings for SNMP access:
• Read Community default = public
• Write Community default = private
• Trap Community default = comtech
6.3.3 SNMP Traps
The CDM-710 has the ability to send out SNMP traps when certain events occur in the modem. For
example, the modem sends out traps when an alarm or a fault occurs in the modem. These include
Unit faults, Tx faults, Rx faults, and ODU faults. A trap is sent both when a fault occurs and when a
fault is cleared.
