SFC6400A/SFC1450A Synthesized Frequency Upconverter User Interfaces
TM106 – Rev. 1.1 4-43
4.6.2.15 Boot Mode (Optional)
1.
Select 37.Boot Mode : from the Controls Menu and press <ENTER>. Scroll through the
various selections to ‘NVBOOT’ and press <ENTER>. The above settings will be enabled
the next time the system is rebooted. If a bootp server is available, the Upconverter can be
remotely configured by selecting bootp mode. This option is currently not available.
4.6.2.16 Community
Each managed station controls its own local MIB and must be able to control the use of that MIB
by a number of management stations. This relates to security concerns. A managed MIB such as
the Upconverter needs to protect itself from unwanted and unauthorized access. SNMP, as defined
in RFC 1157, provides only a limited capability for such security, namely the concept of a
community. An SNMP Community is the relationship between an SNMP Agent and Management
Stations.
1.
To set the community string on the SFC Upconverter, select 34.Community:. Enter the
desired community name and press <ENTER>.
Example: “public”
4.6.2.17 Trap Type and Trap Hosts
Traps enable the converter to notify the management station of significant events such as alarms.
Version1 and version2 Traps are supported at this time. These are Operator selectable using
Terminal Command Number 30. The messages are sent to specific pre-defined hosts. The Primary
and Secondary Trap Hosts IP Addresses are setup using Terminal Commands 31 and 32. Each
host should be acceptable to the transport layer. In other words, the transport layer needs to be
able to open a connection to the entities specified by the trap host fields.
4.6.2.18 Trace Mode
1.
For debugging purposes, a trace mode is specified by the Operator users for various
diagnostic levels.
4.6.2.19 SNMP V1 & 2 Access View
The default access rights for Version 1 and 2 SNMP users are minimal. They are limited to a
system view, and a description of the Upconverter System and Contact Information. For additional
information, go to View-Based Access Control Section. To accommodate older systems, an
Operator user may modify these access rights to allow full or partial read/write access. SNMP
Version 1 and 2 does not use any security measures, therefore users should be very careful when
changing access rights.
4.6.2.20 Key Generation Mode
The password localization algorithm is intensive enough that the Motorola 68332 Embedded
Processor cannot handle the process in a timely manner. This selection allows the Operator user
to optionally store localized keys in non-volatile memory. These keys correspond to a set of
passwords and Modem IP Address. If either changes, the SNMP agent automatically recalculates
the new keys and stores them in non-volatile memory (only if the Key Generation Mode is set to
‘STORE’).
