Secure Ethernet Management Interfaces; Base Modem Interface - Comtech EF Data SLM-5650A Installation And Operation Manual

•
Simple Network Management Protocol (SNMP) - This protocol requires a user-
supplied Network Management System (NMS) or a user-supplied MIB File Browser.
Comtech EF Data supplies the MIB File sets required for the SLM-5650A Modem.
•
Telnet Interface - This non-secure protocol requires use of the user PC's Command Line
Interface (CLI), or a user-supplied terminal emulation program such as HyperTerminal,
PuTTY, or TeraTerm.
•
SSH (Secure Shell) Interface - This protocol requires use of the user PC's CLI, or a
user-supplied terminal emulation program such as HyperTerminal, PuTTY, or TeraTerm.

8.1.1.1

Base Modem Interface

For modems running Base Modem Firmware Version 1.4.6 or higher, the base modem
management can be changed to secure mode by changing the SNMP setting from SNMPv1/v2c
to the SNMPv3mode:
•
The SNMP mode is available using the front panel menu:
SELECT:Configure→Remote→EthernetConfig→SNMP→Version→SNMPv1/v2c or
SNMPv3.
•
After you select SNMPv3 and reboot the modem, the HTTP and Telnet access will be
blocked. This operational change also forces the Trap mode to be SNMPv3Traps.
•
The SNMP Trap Destination Port (default 164) can be changed to a user value in the
SELECT:Configure→Remote→EthernetConfig→SNMP→ Traps→Port menu. If you
are running Base Firmware Version 1.4.8c or higher, you must make sure to only
use port values that are not already in use by other services.
•
Change of the management mode to SNMPv3 is allowable via the HTTP (non-secure)
interface, but you should be aware that, after the modem reboot, HTTP access will no
longer be available. The SNMPv3 mode uses the Base Modem's IP Address via the 'J5
Ethernet' port. The Base Modem HTTPS Interface is accessible by the NP IP Address or
the TRANSEC IP Address.
Ethernet Interface Operation
SNMP is NOT supported by the TRANSEC module.
Telnet is NOT supported by the TRANSEC module.
This interface protocol is supported by the NP Interface Module and
the TRANSEC Module.
