DMD2050E Universal Satellite Modem User Interfaces

MN-DMD2050E Revision 2 4–31

4.4.6.6 SNMP (menu)

A description of OID organization is provided in the MN-DMDREMOTEOP manual.

SNMP MENU

SNMP VERSION {V1 & V2, V3} This selection controls the SNMP Version that will be used in

messaging between the equipment and it’s host.

When V1 & V2 is used, RD COMMUNITY and RDWR

COMMUNITY are used to determine the authorization of an

incoming message.

When V3 is used, three contexts are supported:

public

,

mib2

, and

dev

. Context, Authentication and Privacy are a portion of each

SNMPV3 message.

The

public

context will only allow the user to see the sysoid of the

unit. This is the most restricted access possible and only allows

the unit to be identified by a host SNMP Station.

The

mib2

context allows a user with appropriate authentication to

access the mib2 OIDs and the SNMP OIDs. These are of interest

primarily to network operators not controlling the satellite link.

The

dev

context allows a user with appropriate authentication to

access the device control portion of the MIB. These OIDs are

used to control the devices satellite link and operation.

TRAP VERSION {V1, V2} This controls the type of message format used when a message

trap is generated by the equipment and bound for a SNMP Host.

Messages will only be sent if the unit has been authorized to do

so.

AUTHORIZATION {TRAPS OFF, TRAPS

ON}

This controls the type of message format used when a message

trap is generated by the equipment and bound for a SNMP host.

Messages will only be sent if the unit has been authorized to do

so.

RD COMMUNITY {16 characters of

name}

This menu is only displayed when SNMP VERSION is set to V1 &

V2. This is the community that a host must be acting within when

an OID variable is requested by a V1/V2 SNMP message.

RDWR COMMUNITY {16 characters of

name}

This menu is only displayed when SNMP VERSION is set to V1 &

V2. This is the community that a host must be acting within when

an OID variable is being changed by a V1/V2 SNMP message.

 Modem Status, Alarms & Contact Closures (Section 3.2.)

3.2.6 Terminal Port

This port supports an asynchronous control protocol as described in Chapter 4. It is configured to

support RS-232 signal levels. This port is intended for use in computer-based remote M&C. All

functions of the modem may be monitored and controlled from this port via a common terminal

connected to the Terminal Port. This function is front panel selectable.

The Terminal Mode Control allows the use of an external terminal or computer to monitor and

control the modem from a full screen interactive presentation operated by the modem itself. No

external software is required other than VT-100 Terminal Emulation Software (e.g. Procomm

for a computer when used as a terminal. The Control Port is normally used as an RS–232

Connection to the terminal device. The RS-232 operating parameters can be set using the

modem Front Panel and stored in Non-volatile memory for future use.

IMPORTANT

Refer to the Remote Protocol Manual (MN-DMDREMOTEOP) for the Terminal, Remote

and SNMP screens and protocols.

3.2. Modem Remote Communications (RP)

The Remote Port located on 20 allows for control and monitoring of parameters and functions

via an RS-232 Serial Interface, or RS-45 for RP Protocol. Equipment Remote Mode’ setup

can be entered from the front panel or the Web Browser interface under the System menu. This

requires the user to first set the Remote Port Control to Remote then set the Multidrop Address

as needed followed by setting the Remote Interface to RS232 or RS45.

Control and status messages are conveyed between the modem and all subsidiary modems and

the host computer using packetized message blocks in accordance with a proprietary

communications specification. This communication is handled by the Radyne ink evel Protocol

(RP), which serves as a protocol wrapper’ for the remote M&C data. See the MN-

DMDREMOTEOP manual for more information.
