6.2.2 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 DT-4500-A uses Community Strings as a password scheme that provides authentication
before gaining access to the DT-4500-A 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. You may define three Community Strings for SNMP access:
• Read Community default = public
• Write Community default = private
• Trap Community default = comtech
For proper SNMP operation, the DT-4500-A MIB files must be used with the
associated version of the DT-4500-A Series Downconverter M&C. Refer to the DT-
4500-A FW Release Notes for information on the required FW/SW compatibility.
