SNMP MIB Objects E-2 3160-A2-GB21-80 March 1999 MIB II (RFC 1213) The objects defined by MIB II are organized into 10 different groups. The DSU/CSU implements only those groups where the semantics of the group are applicable to the implementation of a DSU/CSU.
SNMP MIB Objects E-3 3160-A2-GB21-80 March 1999 System Group – “sysObjectID” Object (system 2) This object provides the authoritative identification of the network management subsystem contained in the unit. This object displays the following object identifier: 3160 [ Company OID ].
SNMP MIB Objects E-4 3160-A2-GB21-80 March 1999 Interface Group, MIB II The Interfaces Group consists of an object indicating the number of interfaces supported by the unit and an interface table containing an entry for each interface.
SNMP MIB Objects E-5 3160-A2-GB21-80 March 1999 The supported ifIndexes for the 3160 DSU/CSU are: Net T1 DTE T1 COM port Modem port Auxiliary RS-232 port DCE port 1 DCE por.
SNMP MIB Objects E-6 3160-A2-GB21-80 March 1999 Interface Group – “ifDescr” Object (ifEntry 2) This object provides information about the interface. Each interface displays a text string as shown below: Network T1: “ Network T1 . [ Company Name ] T1 DSU/CSU, Hardware Version: [CCA number for the CSU board]”.
SNMP MIB Objects E-7 3160-A2-GB21-80 March 1999 Interface Group – “ifSpeed” Object (ifEntry 5) This object provides the interface’s current bandwidth in bits per second. The value of this object for each interface is specified as follows: T1 Interfaces: 1,544,000 bps.
SNMP MIB Objects E-8 3160-A2-GB21-80 March 1999 Interface Group – “ifOperStatus” Object (ifEntry 8) This object specifies the current operational state of the interface. The value of this object for each interface is defined as follows: Network T1: The interface is up(1) when no alarm conditions exist.
SNMP MIB Objects E-9 3160-A2-GB21-80 March 1999 Interface Group – Input Counters (objects ifEntry 10 to ifEntry 15) These objects collect statistics on the data received by the COM port, the AUX port, and the MODEM port when these ports are configured as SNMP management links.
SNMP MIB Objects E-10 3160-A2-GB21-80 March 1999 IP Group, MIB II The IP Group objects are supported by the DSU/CSU for all data paths which currently are configured to carry IP data to or from the DSU/CSU, including the MODEM, COM, AUX, carrier SNMP bus, EDL, and FDL.
SNMP MIB Objects E-1 1 3160-A2-GB21-80 March 1999 IP Group – “ipRouteT able” Object (ip 21) The routing table used by the DSU/CSU is supported as a read/write table. Entries in this table may be added, deleted, or changed. Y ou should exercise great caution when adding or modifying routes in the ipRoutingT able.
SNMP MIB Objects E-12 3160-A2-GB21-80 March 1999 IP Group – “ipRouteDest” Object (ipRouteEntry 1) The ipRouteDest object serves as the index to the routing table. Since indexes for tables must be unique, only one route per destination may appear in the table.
SNMP MIB Objects E-13 3160-A2-GB21-80 March 1999 IP Group – “ipRouteAge” Object (ipRouteEntry 10) This object is implemented as a read-only object in the DSU/CSU. In the DSU/CSU, it reflects the value of the route’s time-to-live (in seconds). When displays, a value of 999 represents a route that is retained permanently .
SNMP MIB Objects E-14 3160-A2-GB21-80 March 1999 SNMP Group, MIB II The SNMP Group objects that apply to a management agent are fully supported by the DSU/CSU.

F-1 3160-A2-GB21-80 March 1999 IP Network Addr essing Scenarios F Overview This appendix describes a means of configuring 31xx Series devices in an Internet Protocol (IP) network to provide SNMP or T elnet connectivity .
IP Network Addressing Scenarios F-2 3160-A2-GB21-80 March 1999 Scenario 1 The first scenario (Figure F-1) is a series of standalone 31xx Series devices daisy chained together , with remotes connected via the FDL. In this scenario, all 31xx Series devices are on the same subnet (135.
IP Network Addressing Scenarios F-3 3160-A2-GB21-80 March 1999 Scenario 2 The second scenario (Figure F-2) is a carrier communicating with standalone remotes. This scenario is similar to the previous one, treating the carrier devices as the daisy-chained devices.
IP Network Addressing Scenarios F-4 3160-A2-GB21-80 March 1999 Scenario 3 This third scenario (Figure F-3) shows a local carrier connected to remote carriers that have remote standalones. Each carrier must be on a separate subnet but, as in the previous scenario, the carrier-remote combination can share a common subnet.
IP Network Addressing Scenarios F-5 3160-A2-GB21-80 March 1999 Scenario 4 An alternative addressing scheme, for the network is shown in Figure F-4. This example uses a subnet mask of FF .FF .00.00 for the COM port in the central-site carrier (only), with all of the remaining subnet masks set to FF .
IP Network Addressing Scenarios F-6 3160-A2-GB21-80 March 1999 Scenario 5 Figure F-5 illustrates multiple COM ports on the same carrier connected to different NMSs.
G-1 3160-A2-GB21-80 March 1999 Fr ont Panel Emulation G Overview The DSU/CSU offers functionality through Front Panel Emulation software that is similar to that provided by the DSU/CSU front panel. The DSU/CSU can either be locally or remotely attached to a 386 or higher PC that has at least 4 MB of RAM.
Front Panel Emulation G-2 3160-A2-GB21-80 March 1999 Procedur e T o install Front Panel Emulation software: 1. Insert the diskette into the appropriate drive. 2. Select File from Program Manager . 3. Choose Run. 4. T ype A:INST ALL and click OK. 5.
Front Panel Emulation G-3 3160-A2-GB21-80 March 1999 Starting Fr ont Panel Emulation If the DSU/CSU selected is not locally attached to the PC, you must first dial to the remote DSU/CSU before starting front panel emulation. The modem attached to the PC must support A T commands for the Front Panel Emulation software to successfully place the call.
Front Panel Emulation G-4 3160-A2-GB21-80 March 1999 6. If you chose a Local destination, click on the Execute button. If you chose a Remote destination, enter the telephone number of the far-end DSU/CSU in the Phone Number field, then click on the Dial button.
H-1 3160-A2-GB21-80 March 1999 Asynchr onous T erminal Operation H Overview Y ou can configure and manage the DSU/CSU from an asynchronous (async) terminal that is configured for 9.
Asynchronous T erminal Operation H-2 3160-A2-GB21-80 March 1999 Initiating an Asynchr onous T erminal Session Once the appropriate configuration option changes have been made and access is established, the Main Menu screen appears (unless a password is required).

Asynchronous T erminal Operation H-4 3160-A2-GB21-80 March 1999 Menu Organization Async terminal menus differ from front panel menus in that they typically do not use abbreviations and, in some cases, provide a more direct access to an option or function.
Asynchronous T erminal Operation H-5 3160-A2-GB21-80 March 1999 Using Asynchr onous T erminal Scr eens There are three types of async terminal screens.
Asynchronous T erminal Operation H-6 3160-A2-GB21-80 March 1999 T able H-2. Keyboard Keys Keyboard Key Usage Ctrl-a Moves the cursor between the Screen area and the Screen Function Keys area. Esc Returns to the previous screen. Ta b Moves the cursor to the next field.
Asynchronous T erminal Operation H-7 3160-A2-GB21-80 March 1999 Setting Customer Identification The customer identification is used to uniquely identify the DSU/CSU. Procedur e T o change the customer identification (Customer ID): 1. From the Main Menu screen, select Control.
Asynchronous T erminal Operation H-8 3160-A2-GB21-80 March 1999 Displaying LED Conditions The same conditions monitored by the front panel LEDs can also be monitored by the Display LEDs screen. This screen is most useful when the DSU/CSU is being accessed remotely .

Asynchronous T erminal Operation H-12 3160-A2-GB21-80 March 1999 Establishing Access Security on a Port Although the password feature is available, it is not required. If used, it ensures access security before control is passed to a device connected to a port.
Asynchronous T erminal Operation H-13 3160-A2-GB21-80 March 1999 Setting a Password In addition to establishing access security on a port (refer to the previous section, Establishing Access Security on a Port ), the password itself is set. Unless you specify otherwise, the password is null.
