SNMP Community Strings

In SNMP v1/v2c, the SNMP 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.
The modem uses Community Strings as a password scheme that provides authentication before
gaining access to the modem agent's MIBs. They are used to authenticate users and determine
access privileges to the SNMP agent.
Type the SNMP Community String into the user-supplied MIB Browser or Network Node
Management software.
The user defines three Community Strings for SNMP access:
•
Read Community
•
Write Community
•
Trap Community
Note: Maximum number of characters for community strings shall not exceed 20. All printable
ASCII characters, except '\' and '~' are allowed. No trailing spaces for community strings.
For proper SNMP operation, the modems MIB files must be used with the
associated version of the modems firmware.
5.4.3

SNMP Traps

These include unit faults, TX faults, and RX faults. A trap is sent both when a fault occurs and is
cleared.
The "Traps" file only needs to be compiled if SNMPv1 traps are to be used. Which style of traps
the modem sends can be configured by the user using the SLM5650CSNMPTrapVersion OID.
The modem supports the following MIB2 SNMPv1traps / SNMPv2 notifications:
MIB2 SNMPv1 trap: Authentication Failure
MIB2 SNMPv2 notifications: Authentication Failure
