3.4.2 SNMP Community Strings

In SNMP v1/v2c, the SNMP Community String is sent unencrypted in the SNMP

packets. The network administrator must take caution to ensure that SNMP packets

travel only over a secure and private network if security is a concern.

The SSPA uses Community Strings as a password scheme that provides authentication before

gaining access to the router 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.

Three Community Strings are defined for SNMP access:

• Read Community

default = public

• Write Community

default = private

• Trap Community

default = comtech

For proper SNMP operation, the SSPA MIB files must be used with the associated

version of the SSPA M&C. Please see the “SSPA FW Release Notes” for information

on the required FW/SW compatibility.

3.4.3 SSPA SNMP Traps

The SSPA has the ability to send out SNMP traps when certain events occur in the unit. The SSPA

sends out traps when a fault occurs in the unit. A trap is sent both when a fault occurs and is

cleared.

The SNMP agent supports both “SNMPv1” and “v2c”. The “Traps” file only needs to be

compiled if “SNMPv1” traps are to be used.

You may configure which style of traps the SSPA sends by using the SSPASNMPTrapVersion OID.

The MIB2 v1traps / v2 notifications supported by the SSPA are as follows:
