Introduction

Introduces Network ConÞguration Utilities device conÞguration tools.


Network Configuration Utilities is a set of applications, accessible from SPECTRUM Search Manager, that enables you to perform the following device management tasks for Cabletron devices that are modeled in SPECTRUM:

• Configure and execute TFTP firmware image downloads using the Firmware Download Tool.

• Modify community strings using the Modify Community Strings Tool.

Firmware Download Tool

The Firmware Download tool enables you to configure and execute TFTP firmware image file (

.fls

format) downloads to Cabletron network devices that implement the Cabletron Private Enterprise ctDownLoad MIB. This tool supports online downloads only. It does not support offline downloads (

.hex

format).

Modify Community Strings Tool

The Modify Community Strings tool enables you to modify community strings for Cabletron network devices that support either the chassis (Rev. 1.07.00, which supports global community strings) or ctChassis2 MIBs. Devices that support these MIBs contain up to three names, one for each of three privilege levels: read-only, read-write, and super-user.

Introduction Secur i ty: Conf igurat ion Pr iv i leges


Security: ConÞguration PrivilegesTo configure devices with Network Configuration Utilities applications, you must have the following SPECTRUM and device security privileges:

• A SPECTRUM user model with write privileges. See Security and User Maintenance for more information about SPECTRUM user privileges.

• Super User community name access to modify device community strings, and Read/Write community name access to download firmware.

Getting StartedThis section describes how to access Network Configuration Utilities applications from SPECTRUM Search Manager.

Network ConÞguration Utilities and Search ManagerSPECTRUM Search Manager enables you to compile a list of the models for the devices you want to configure and provides access to Network Configuration Utilities applications. See the SPECTRUM Search Manager User’s Guide for details on working with the Search Manager.

Accessing Network ConÞguration Utilities ApplicationsTo access Network Configuration Utilities applications:

1 Open the Search Manager application and compile a models list.

2 Select one or more models, and then choose one of the following options from the Management menu:

• Download FirmwareSee the Downloading Firmware section for details.

• Modify Community NameSee the Modifying Community Strings section for details.



Describes how to use the Network ConÞguration Utilities Firmware Download tool to conÞgure and execute TFTP Þrmware image downloads to Cabletron devices.

Firmware Download OverviewFirmware is the software instruction set saved to Flash EEPROM in a managed (or an “intelligent”) network device. It provides the device with the capacity to be managed through in-band console management or out-of-band, SNMP-compliant management applications such as SPECTRUM.

The firmware download procedure involves specifying download parameters (e.g., the name and source of the firmware image file and the device(s) to which the file is to be downloaded) and then starting the download via TFTP (Trivial File Transfer Protocol).

Note:Note:

SPECTRUM Network Configuration Utilities does not contain TFTP server software. You must install and configure a TFTP server in order to use the Firmware Download Tool.

Several commercial, shareware, and freeware TFTP server software packages are available for Windows NT. Aprisma offers a free TFTP server for NT. For instructions on downloading and configuring the Aprisma TFTP server, point your Web browser to: http://www.aprisma.com/support/techtips/files/tk0020-9.html.

TFTP server software is included with the standard Solaris distribution. For instructions on configuring a Solaris workstation as a TFTP server, point your Web browser to: http://www.enterasys.com/support/techtips/tk0019-9.html.See also the SPECTRUM Enterprise Configuration Manager User’s Guide for more information.

Describes how to use the Network ConÞguration Utilities Modify Community Strings Tool to modify community strings for Cabletron devices.

Community Strings OverviewFor all of Cabletron’s newer intelligent devices — including all SmartSwitch modules — MIB information is organized into a series of “components,” each of which controls a defined set of logically grouped objects. For example, the EMM-E6’s bridging information is organized into its own component and repeater information resides in three separate components, one for each of the EMM-E6’s internal repeater channels.

In the original versions of these devices, each MIB component is protected by its own set of user-configurable read only, read/write, and superuser community strings. These names determine the level of access (read only, read/write, or superuser) that will be granted to the information controlled by each component.

Newer versions of devices with this component-based MIB architecture have been simplified somewhat. These devices support a single, global set of community strings, with small modifications added automatically to accommodate multiple instances of the same MIB component (as occurs in multi-channel Ethernet repeaters or multi-ring Token Ring devices).

The Modify Community Name Tool supports those Cabletron devices which implement global community strings, whether the devices support the chassis MIB (Rev. 1.07.00 or later), or the ctChassis2 MIB.

The Modify Community Strings Tool enables you to modify the community strings of multiple devices in a single step. You can also modify the community string of the SPECTRUM model representing each device.

Modifying Community Strings Conf igur ing the Community Name Change


ConÞguring the Community Name Change

Before You StartBefore you start a community name change, make sure the models list compiled (or selected) in Search Manager and displayed in the Modify Community Strings window represents intelligent devices that implement global community strings. Devices of differing model types can be selected as long as they support the chassis MIB (Rev. 1.07.00 or later), or the ctChassis2 MIB.

To access the Modify Community Strings Tool:


2 Select one or more models, and then choose Modify Community Strings from the Management menu.

The Name Change Information Window appears.

Note:Note:

If for any reason some or all of the device(s) in your list are invalid (e.g., devices not supported by the Modify Community Strings application, devices unable to be contacted, device models for which you do not have write access, etc.), an Invalid Models Window appears first. For more information about the Invalid Models Window, see Verifying the Operation/Exception Handling.



Figure 5: Name Change Information Window

ConÞguring and Starting the Change1 In the Name Change Information Window, set either or both of these

parameters:

• New SPECTRUM Community Name• Current Super User

and one or more of these parameters:

• Read Only User• Read Write User• Super User

See Table 8 for more information about these parameters.

Tip:Tip:If you set the New SPECTRUM Community Name string you need not set any further community name strings.If you set the Current Super User community name string (but not the New SPECTRUM Community Name string) then you must set one or more of the above community name strings.

New Change Information WindowThe Name Change Information Window provides a means of entering various community name strings for Cabletron’s intelligent networking hardware devices. Table 8 lists all fields and buttons in this window and describes their functions.

Table 8: Name Change Information Window Fields and Buttons

Field/Button Description

New SPECTRUM Community Name

The new internal SPECTRUM model community name string. This value, which is written to the model (not the device), determines the level of access that SPECTRUM has for each device. It should match either the read-only, read/write, or super-user community name strings on the selected reachable device(s).



Current Super User The Super User community name string for the selected reachable device(s), which is used to perform write operations to each device. The text fields in the New Community String Values area become active as soon as you enter something in the Current Super User field.

Read Only User The new read-only community name string for the selected reachable device(s). This value is written to the devices.

Read Write User The new read/write community name string for the selected reachable device(s). This value is written to the devices.

The color of the status icon indicates the condition of the connection. Color-coded conditions include green (complete service), yellow (degraded service), and red (total loss of service).

The Connection Log provides date/time information and status messages for the service selected in the dialog box. Possible messages include, “Connection lost”, and “Connection re-established.”

Verifying the Operation/Exception HandlingThe Modify Community Strings window’s Models List Panel provides visual cues as to the status of a community name change via text displayed in the Status column. Also, clicking on the Operations Status tab in the Model Information Panel displays relevant information concerning the status of the community name change. See Table 12 for more information.

In addition, more detailed information concerning the change is contained in log files, located in the /tmp directory on UNIX, and in the directory specified by the TEMP environment variable on Windows NT.

Note:Note:

On Windows NT, if you change the directory specified by the TEMP environment variable, you must re-initialize processd in order for Modify Community Strings to correctly place the log files. For instructions on re-initializing processd, see the SPECTRUM manual, Database Management.
