SNMP Community Strings
The CDM-710G uses community strings as a password scheme that provides authentication before
gaining access to the CDM-710G 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:
•
•

cleared.
