Snmp Community Strings; Snmp Traps - Comtech EF Data SLM-5650A Installation And Operation Manual

8.2.2

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 SLM-5650A 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
The 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 SLM-5650A MIB files must be used with the
associated version of the SLM-5650A base modem M&C. Please refer to the
SLM-5650A SW Release Notes for information on the required FW/SW
compatibility.
8.2.3

SNMP Traps

The SNMP traps include the Unit faults, TX faults, and RX faults. A trap is sent both when a fault
occurs and when it is cleared.
You need to compile the "Traps" file into the MIB Browser library only if you intend to use Traps.
When you set the modem for SNMPv1/v2c, you may select Trap (v1) or (v2c) types; the modem
automatically forces Trap Version(v3) when you select SNMPv3 mode. You may also use the
slm5650SNMPTrapVersion OID to configure the Trap (v1) or (v2c) type.
You can assign two Trap destination addresses. If you are running Base FW Version 1.4.8c or
higher, you can assign the destination Port – Port 164 is the default trap port.
The modem supports the following MIB2 SNMPv1traps / SNMPv2 notifications:
MIB2 SNMPv1 trap: Authentication
Failure
MIB2 SNMPv2 notifications:
Authentication Failure
Ethernet Interface Operation
default = public
default = private
default = comtech
