About the SNMP DSU

Model 7610 SNMP DSU Features

The SNMP DSU provides an interface between the customer premises equipment (CPE) and a DDS network. Its features include:

 SNMP (Simple Network Management Protocol) Management. Provides

network management via an industry-standard SNMP management system.

 In-band Management Channel (IMC). Provides remote management via

SNMP or Telnet session capability over the DDS network.

 Async Terminal Interface (ATI). Provides a menu-driven VT100-compatible

interface for configuring and managing the DSU locally or remotely by Telnet session or External Modem.

 Local Management. Provides local management via an:

— Async terminal connection through the Terminal port — NMS connection through the Management port

 Remote Management. Provides remote management:

— Out-of-band, using an external modem through the Terminal port or

Management port

— Via Telnet through the Management port or the In-band Management

Channel (IMC)

 DDS Rates. Operates at 56 and 64 kbps CC (clear channel).  LADS Operation (Local Area Data Set). Operates at 56 and 64 kbps

full-duplex (also called a limited distance modem).

 Autorating of Line Rate. Establishes the line rate from the network receive

signal and automatically adjusts to the detected line rate.

 Data Port Rates. Supports the same rates as the DDS or LADS operating

rates, except when the IMC is enabled.

MIB Support

1-2

The following MIBs are supported:

 MIB II (RFC 1213 and RFC 1573) – Defines the general objects for use with

a network management protocol in TCP/IP internets and provides general information about the DSU. MIB II is backward-compatible with MIB I.

 RS-232-Like MIB (RFC 1659) – Defines objects for managing RS-232-type

interfaces (e.g., V.35, RS-422, RS-423, etc.) and supports synchronous data ports and management communication ports on the DSU.

 Enterprise MIB – Supports configuration, status, statistics, and tests on the

DDS network interface.

Accessing the ATI

You can communicate with the Asynchronous Terminal Interface (ATI) using one of the following methods:

 Direct connection through the Terminal port.  Dialing in through an external modem to the Terminal port.  Telnet session through the Management port (locally or via an external

modem).

 Telnet session through the In-band Management Channel (IMC).

NOTE:

Only one asynchronous user interface session can be active at a time, and another user’s session cannot be forced to end. To automatically log out a user due to inactivity, enable the Inactivity Timeout option (see Terminal Port

Options, Table A-4).

The user interface is blank until activated. Press Return to activate the user interface. Security can limit ATI access several ways. To setup security or a login ID, refer to

Connecting to the Terminal Port

Verify that the settings of the device that you connect to the Terminal port match these factory-loaded option default settings:

 Data rate set to 9.6 kbps.  Character length set to 8.  Parity set to None.  Stop Bits set to 1.

Controlling SNMP Access

There are three methods for limiting SNMP access.

 Disable the SNMP management option.  Assign SNMP community names and access levels. The DSU supports

SNMP V ersion 1, which provides limited security through the use of community names.

 Limiting SNMP access through validation of the IP address of each allowed

SNMP manager.

Assigning SNMP Community Names and Access Levels

The DSU can be managed by an SNMP manager supporting the SNMP protocol. The community name must be supplied by an external SNMP manager accessing an object in the MIB.

To define SNMP community names, follow this menu selection sequence:

Main Menu→Configuration→Load Configuration From→Edit SNMP & Communication→General SNMP Management

Refer to General SNMP Management Options, Table A-10, to:

 Enable SNMP Management.  Assign the SNMP community names of the SNMP Managers that are allowed

to access the DSU’s Management Information Base (MIB).

 Specify read or read-write access for each SNMP community name.

Limiting SNMP Access through the IP Addresses of the Managers

The DSU provides an additional level of security through validation of the IP addresses.

The SNMP Management option must be enabled. To control SNMP access with IP addresses, follow this menu selection sequence:

Main Menu→Configuration→Load Configuration From→Edit SNMP & Communication→SNMP NMS Security Options

Refer to SNMP NMS Security Options, Table A-11. The SNMP access can be limited by:

 Enabling NMS IP address validation to perform validation checks on the

IP Addressing

Selecting an IP Addressing Scheme

You can select from many IP addressing schemes to provide SNMP NMS connectivity. Review the following information in preparation for selecting an IP addressing scheme.

 Assign IP addresses to:

— The Management port

— The IMC

Refer to the

 When the Routing Information Protocol (RIP) option is set to Proprietary,

IP routing information is automatically passed between interconnected DSUs from the network side. Refer to Management Port Options, Table A-5.

However, verify that a route to the subnet(s) is set in the NMS’s or local router’s routing table. This equipment will not automatically receive routing information due to the proprietary protocol.

The gateway to subnet(s) is through the DSU connected to:

— The LAN using a LAN adapter, or — A router, terminal server, or NMS via PPP or SLIP link-layer protocols

 Each DSU’s routing table supports a maximum of 20 routes, even though a

single route is all that is needed to reach every device on a subnet.

 Set a default route only for devices directly connected to the DSU’s

Management port.

 Any legal host address is allowed for a given subnet; the address choice

within the subnet is completely arbitrary.

IP Addressing

IP Addressing Scheme Examples

Management of IP addressing is based upon individual IP addresses assigned to each interface. The IP interfaces for the unit are the:

 Management port: Set the Port Use option to Net Link; see Management Port

Options, Table A-5.

 IMC: Set the In-Band Management Channel Rate (bps) to 1600, 4000, or

8000 bps; see Network Interface Options, Table A-2.

NOTE:

For IP addressing, involve your Information Systems (IS) department since the department decides on the IP addressing scheme used for your organization.

The following illustrations and examples apply to IP management traffic only. The subnet mask shown for these examples is 255.255.255.000.

IMC Connection – Same Subnet

In this example, DSU A is connected to:

 The NMS, at the central site, via a LAN adapter  A remote unit, DSU B, through the proprietary IMC

NOTE:

Interconnected DSUs will automatically pass routing information between each other using a proprietary protocol. However, a static route to subnet 135.18.2.0 must be set in the routing table of the NMS Host.

Using Routers to Route DSU Management Data

In this example, the DSUs:

 Receive their management data through the Management port connection to

the AUX port of the router.

 Do not route the data among themselves. Routers route management data

for the connected DSUs using the management data path between the routers.

The illustration shows each DSU with its own subnet. This subnet is independent of the subnet on the LAN, which is supported by the local router. This enables the router to distinguish the data destined for the DSU from the data for the LAN.

MIB Descriptions

Interfaces Group

The Interfaces Group as defined in RFC 1573 consists of an object indicating the number of interfaces supported by the unit and an interface table containing an entry for each interface. Since RFC 1573 is an SNMPv2 MIB, it is converted to SNMPv1 for support by the unit. The following table provides clarification for objects contained in the Interfaces group when it is not clear how the object definition in RFC 1573 is supported by the unit.
