Trap Destination Addresses
Enter the trap destination IP addresses in the Trap Destination Address dialog
boxes. These are the IP addresses where all traps/notifications will be sent. If a
network management application is running in the network, it should be config-
ured to receive traps and its IP address should be entered here.
Note: The VMS does not use SNMP trapped messages; do not enter the VMS
server address in this field.
Community Strings
The modem/router uses community strings as a password scheme that provides
authentication before gaining access to the agent’s MIBs. In SNMP v1/v2c, the
community string is sent un-encrypted in the SNMP packets.
Caution: The network administrator must ensure that SNMP packets only
travel 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 strings are entered into the modem/router using the fields
shown in figure 2-40, and are used to authenticate users and determine access
privileges to the SNMP agent.
The user defines three Community Strings for SNMP access:
• Read Only Community (default = public) — GET community string that
allows GET operations to all portions of the IP Module Controller and
modem MIBs.
• Read Write Community (default = private) — SET community string
that allows SET operations to all portions of the IP Module Controller and
modem MIBs.
• Trap Community (default = public) — Community string that will be set
in the Community field of all outgoing traps. This field on the trap PDU
may be checked by the network manager application to determine if the
trap came from a “trusted” agent.
