14.4.1 Management Information Base (MIB) Files
MIB files are used for SNMP remote management and consist of Object Identifiers
(OIDs). Each OID is a node that provides remote management of a particular function. A
MIB file is a tree of nodes that is unique to a particular device.
There are five MIB files associated with the CDM-570 :

Change Specifics:
14.4.2 SNMP Community Strings
The modem uses community strings as a password scheme that provides authentication
before gaining access to the modem 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:
• Read Community default = public
• Write Community default = private
• Trap Community default = comtech
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.

Subject: Revised 14.5 Telenet Interface for HyperTerminal
Date: March 15, 2006
Document: CDM-570/570L Installation and Operation Manual, Revision 3,

Comments:
Add paragraph and screen captures to 14.5 Telnet Interface. This information will be
incorporated into the next revision.
Change Specifics:
There is a disadvantage when using Windows DOS as Telnet Client. Since Windows DOS
cannot translate a ‘\r’ to a ‘\r\n’ for the messages coming from Telnet Server, the multi-line
command response (for example, FRW? response) will be displayed as one line, with the latter
lines overwriting the previous lines.
In order to view the full response messages, CEFD recommends using HyperTerminal
configured as Telnet Client. To do so, configure the HyperTerminal as following:
1. Connect using TCP/IP instead of COM1 or COM2;
2. ASCII setup: check both the "Send line ends with line feeds" and "Append line feeds to
incoming line ends" options.
See the following screen captures for examples.
