Introducing the

Network

Management

Module

The Asanté 2072 Network Management Module (NMM) provides overall network management for the AsantéHub 2072 or

NetStacker hub. By plugging the module into any one of the expansion slots in the chassis, the NMM works with the

AsantéView network management software to monitor and control AH 2072 NMM or NetStacker modules, gather statistics, monitor network traffic, and set alarm thresholds. Figure 1 shows an example of the NMM front panel.

Asanté 2072 Network Management Module (NMM)

You do not have to have an NMM in the chassis for the repeater modules to function properly.

The NMM’s major purpose is to manage the hub and gather network statistics.

The primary features of the NMM include:

AsantéView management capability for in-band and out-of-band

Simple Network Management Protocol (SNMP) support

Segment control

Remote network management via RS232

Terminal connection via RS232

Comprehensive LEDs

Upgrading capabilities

Hub Alert Audio/Visual Aid

Interfacing with AsantéView network management software, the

NMM allows you to proactively manage your network via in-band and out-of-band management from either Apple Macintosh

®

or

Microsoft Windows

®

PC platforms.

The NMM has built-in SNMP support. When running AsantéView management software from a Macinosh or PC, you can control the

AsantéHub 2072 or NetStacker hub.

The NMM also supports both management information base (MIB)

I and II, as well as Asanté’s private MIB extension.

Page 4

Introducing the Network Management Module

With the NMM’s Segment Control buttons, you can manually isolate any AH 2072 NMM or NetStacker module, or assign it to either of the chassis’ two segments. This can also be accomplished remotely using AsantéView In-Band and Out-of-Band software.

Segment Control allows you to monitor and control both segments of the AsantéHub 2072 and its repeater modules.

The module’s RS232 port and its AsantéView Management Station

(AMS) Link offer remote (out-of-band) network management control. With these two connections and an AsantéView Management

Station, you can gather statistics and set parameters for as many as twelve daisy-chained Asanté hubs. You can also use the RS232 port as a local management port. Used in this way with terminal emulation software, you can gather statistics and set parameters for an individual Asanté hub.

LEDs for both Ethernet segments are displayed on the NMM front panel or can be viewed from an AsantéView Management Station.

The LEDs display many types of traffic statistics, such as late collisions, misalignments, fragments, and short events, as well as segment utilization and collision percentages in bar graph form.

The NMM is easy to upgrade because it has Flash EEPROM memory. To upgrade to the latest hub software (image code), download the NMM’s microcode upgrades from an AsantéView Management

Station or from a third party TFTP server directly through the network. See the appropriate AsantéView User’s Guide or third-party server documentation for more information on the upgrade procedure.

The AsantéHub 2072 MIB is a text file distributed by Asanté Technical Support. The file can also be obtained using anonymous FTP

(File Transfer Protocol) from Asanté’s Internet accessible FTP server (see "Asanté Technical Support" on page 2 for more information).

For MIB compilation instructions, refer to your management console’s documentation.

Installation

Grounding Requirements

Checking Package

Contents

Warranty Card

Installing the NMM

The NMM installation consists of:

Grounding yourself

Checking package contents

Installing the module and checking its LEDs

Connecting the module to other devices

Before unpacking or handling the module, you must attach the grounding strap (provided in the package) to your wrist to discharge static electricity from your body or clothes. Attach the clamp end to the hub chassis, which should already be grounded properly.

The Asanté AH 2072 NMM package contains the following items:

Warranty card

This installation guide

AsantéHub 2072 NMM in anti-static packaging

There may also be a “Read Me First” sheet in the package. Always read the “Read Me First” document before you install. It contains the most up-to-date information about your installation (this information may not be included in the manual).

Filling out your warranty card and sending it in promptly is important. If you do not send it in within 30 days after the date of purchase, you may not be eligible for the NMM’s 5-year warranty.

This installation assumes that you have already installed the

AsantéHub 2072 or NetStacker chassis. To install the NMM, do the following steps:

1 Observing the anti-static grounding procedures (see

“Grounding Requirements” earlier in this document), remove the module from its anti-static packing.

Handle the module only by its edges. Do not touch chips or connectors.

Do not force the module into a slot. Forcing the module into a slot can damage the backplane.

Installing the NMM

Hand-tighten the module to the chassis. Make sure you fasten both spring-loaded screws in unison and apply the same amount of torque so that the module attaches evenly to the chassis.

If the power to the hub was on when you installed the

NMM, reset the hub. If you powered down the hub before installing the NMM, power up at this point.

Check that the CPU LED (located to the right of the

Reset button) blinks. A blinking CPU LED indicates that the NMM is functioning properly.

Cable

Connections to

Other Devices

The NMM’s front panel has two connections (out-of-band) that provide attachment to other hardware devices such as PCs, Macs, or dial-up modems:

AsantéView Management System (AMS) Link

RS232 connector

AMS Link

The AMS Link specifically provides the following types of device connections:

PC and Macintosh connections for Out-of-Band network management

Hub interconnections for out-of-band (daisychained from one hub to another)

The two AMS Link connectors are RJ-45 ports that provide an interface to a PC or Macintosh running AsantéView Out-of-Band management software. You can daisy-chain as many as twelve hubs via the AMS Link for simultaneous out-of-band management.

Connecting Hubs in an

Out-of-Band Daisy-Chain

To connect hubs in an out-of-band daisy-chain using the AMS Link connector:

1 Be sure the length of the daisy-chain, from the management station to the hub furthest away, is less than

2000 feet.

2 Connect a straight-through RJ-45 extension cable ( not provided in the package) from an AMS Link connector on the first hub to an AMS Link connector on the second hub.

Connect the hubs in a daisy-chain as shown in

Figure 4 on page 13.

3 To enable termination in the Out-of-Band daisy-chain, set DIP Switch 1 DOWN (END) on the end hub only.

4 On all other hubs in the chain, set DIP Switch 1 UP

(THROUGH).

This section contains:

General guidelines for using the Asanté Remote

Management System menus

A short tutorial for navigating the system menus

The icons, menus, and screens for accessing the

Asanté Remote Management System may differ depending on what computer you’re using. Once you’re in the Asanté Remote Management System, the menus look the same.

General Guidelines

Here are some general guidelines for using the Asanté Remote

Management System menus:

To invoke a command, type the letter of the alphabet listed in the <Cmd> column in the Configuration menu (don’t type < >). There’s no need to press the Return key after typing the letter.

When you press c for the Configuration menu, you’re prompted for a password. The default password is Asante (the password is case-sensitive).

Type the password, then press the Return key.

When you input or change data, you do need to press the Return key to send the change to the hub.

If you go into a data input area that’s blank and want to leave it blank, just press the Return key.

If you go into a data input area and want to leave the field’s contents as-is, you have to retype the entire line (pressing the Return key deletes everything on that line).

Typically you press q to leave the menu you’re on.

You’re returned to the previous menu.

Pressing q at the Asanté Remote Management System Main menu closes the Telnet connection with the hub.

Choosing Quit from the File menu closes the Telnet application.

Menu Tutorial

The following short tutorial navigates through some of the Asanté

Remote Management System menus. The tutorial adds the text

“2072” to a hub’s previously-defined name. All examples show Telnet running on a Macintosh.

We start with a Telnet session established with an

AsantéHub 2072 . The Asanté Remote Management System Main menu appears, shown in Figure 16.

(Tutorial)

1 Type g to show the current configuration. Figure 17 shows an example.

Page 25

AsantéHub 2072 Network Management Module Installation Guide

Figure 17 Example General Configuration Screen

The example shows “Office Hub” as the current hub name. If the hub has not had a name assigned to it previously, the Hub Name field will be blank.

2 Press the space bar to continue. The Asanté Remote

Management System Main menu appears again (see

Figure 16 on page 25).

3 Type c from the Asanté Remote Management System

Main menu. The prompt “Enter Password” appears below the Command> line, shown in Figure 18.

Page 26

Using the Asanté Remote Management System

5 Type a from the Configuration menu. This takes you to the System Administration Information menu, shown in Figure 20.

Figure 20 System Administration Information Menu

Note that the current hub information—name, contact, and location—displays above the menu choices on this screen (some or all of these fields may be blank for your particular hub).

We’ll change the example hub’s current name, “Office

Hub”, to “Office Hub 2072.” (You can type a different name if you wish.)

6 Type n to set the hub’s name. The Command> line changes to prompt you for the new name, as shown in

Figure 21.

Page 28

Using the Asanté Remote Management System

Figure 21 Enter Hub Name Prompt

7 Type Office Hub 2072 (or a different name if you wish) and press return .

Note in the above example that even though it looks like we could just add the text “2072” to the end of the hub name, we actually have to type the entire line. If we typed “2072” only, the hub would be renamed

“2072” rather than “Office Hub 2072”.

Telnet sends the new name to the hub and the screen refreshes to display the current information. Figure 22 shows the new hub name, “Office Hub 2072”, used in this example.

Configuration Menu

Descriptions

The following paragraphs describe the Configuration menu choices you can use to configure your hub.

Page 31

AsantéHub 2072 Network Management Module Installation Guide

System Administration Information

Use to enter and transmit text strings defining the hub name, contact, and location.

Out-of-Band Parameters

Use to enter and transmit the Out-of-Band baud rate, dial string to be used when the AMS dials out on a modem, and the

Out-of-Band password. Baud rate changes also will be effective on the terminal.

The Out-of-Band password applies when you are establishing an Out-of-Band connection with the hub using AsantéView

Out-of-Band and the RS232 port. See the appropriate Asanté-

View User’s Guide for more information. There is no password checking when you use the direct link to the hub using the

AMS Link ports.

TCP/IP Parameters

Use to define the hub IP address, IP subnet mask, and default router IP address. The new parameters take effect after you restart the hub.

Bootstrap Parameters

Use to define where the hub should boot from (local from

EEPROM or from a remote server), what SNMP protocols should be used during the remote boot process, and the

IP address of the remote server.

Asanté recommends that you use the default setting of local .

The Boot File Name referred to in the menu is the configuration file residing in the AsantéView AMS Images folder in the

Macintosh version, and the same directory as the AMS executable (In-Band or Out-of-Band) in the Windows version

( C:\AVIEW is the default). The default name is 2072h.cfg

for the

AsantéHub 2072 See the appropriate AsantéView User’s Guide for more information.

SNMP Parameters

Use to define a variety of SNMP parameters:

❏ Read Community string

❏ Write Community string

❏ Authentication trap

❏ Trap receiver table parameters

Page 32

Configuration Menu

Group Parameters

Use to assign to a segment or isolate, meaning assign to no segment, a group. (A group is defined as all of the ports on an

AsantéHub 2072 or NetStacker hub module.) Pressing n (Select

Next Group) repeatedly cycles through the group choices.

Pressing s (Assign/Isolate Group Segment) repeatedly cycles through the segment choices—1, 2, or Isolated for the

AsantéHub 2072 ; 1 or Isolated for the NetStacker hub.

If you isolate a group from both segments (that is, assigned it to no segment), you’ll lose your Telnet connection and SNMP capabilities. You then can manage the group only by using AsantéView Outof-Band.

If your AsantéView Management Station (AMS) is on one segment, and you change the NMM to the other segment, you will not be able to communicate with the NMM (provided a bridge does not exist between the two segments). You lose your

Telnet connection and SNMP capabilities.

You can reestablish communication with the module by changing the segment using the Select

Slot and Change Segment buttons on the hub, by connecting your AMS to the other segment, or by using AsantéView Out-of-Band.

Port Parameters

Use to enable/disable a specific port’s connection, link integrity, and auto polarity testing. Pressing N (uppercase N) repeatedly cycles through the available groups. Pressing n repeatedly cycles through the ports within a group.

Node Summary

Use to display a summary of node activity on the hub. The hub monitors all packets passing through its ports. Pressing G or g cycles back and forth through the available groups. Pressing P or p cycles back and forth through the ports within a group.

Pressing c (chg cntr) repeatedly cycles through the available data counters: Good Frames, Bad Frames, Broadcast, Multicast,

Short Event, Runts, Frame Too Long, SFD Missing, Fragments,

Alignment Errors, DRM Errors, IFG Errors, Collisions, Late Collisions, Auto Partitions, MJLPs, and Readable Octets.

Page 33

AsantéHub 2072 Network Management Module Installation Guide

Pressing a sets the node summary aging time, which is the amount of time the hub stores node summary data. Each time a new device uses a port, or the frame type changes, the hub stores an entry in the Node Summary log. If the hub does not receive data again from that node within the specified aging time, the node data is purged from the log.

If the aging time is set to a short time span, problem nodes may time out and be dropped from the

Node Summary table.

Console Password

Use to set the password for the terminal interface connection.

The password is case-sensitive, and it can be up to 20 characters. You’re prompted for this password when you choose the

Configuration menu from the Asanté Remote Management System Main menu. The default password is Asante.

Telnet Idle Timeout

Use to set the length of idle time, in whole minutes, before Telnet closes the current connection. The default is 20 minutes.

To keep Telnet from timing out at all, set the idle time to zero minutes.

Toggle Segment Switch Lock/Unlock

Use to enable/disable manual segment control. When manual segment control is disabled, pressing the two segment control buttons on the standard NMM faceplate does nothing.

Reset EEPROM on NMM Module to Default

Use to set user-defined settings for the NMM to their default values. The hub name, hub contact, hub location, dial string, and boot file name fields become blank, and the boot server

IP address is set to all zeros. These changes occur immediately.

The hub IP address, subnet mask, and default router IP address are set to all zeros. Console Password is set back to its default, which is Asante.

Telnet Idle Timeout is also set back to its default, which is 20 minutes. These changes occur on hub restart.

Reset EEPROM on All Repeater Module(s) to Default

Use to set port parameters—Port Connection, Link Test, and

Auto Polarity Correction—to the default value, which is

Enabled. These changes occur immediately.

Page 34

Configuration Menu

Reset System

Use to send an immediate Reset command to the hub, causing a soft reset. Terminal communication is lost briefly, then automatically reestablished. If you’re using Telnet, the connection is closed.

Exit Configuration Menu

Use to leave the Configuration menu and go back to the Asanté

Remote Management System Main menu.

Changing the Password

You’re prompted for a password when you choose the Configuration menu from the Asanté Remote Management System Main menu. (The default password is Asante.

)

You can change this password if you wish. The password is casesensitive, and it can be up to 20 characters.

Use the following procedure to change the current password. All examples show Telnet running on a Macintosh. We start with a

Telnet session established with an AsantéHub 2072 .

1 From the Asanté Remote Management System Main menu, press c for Configuration. The prompt “Enter

Password” appears.

2 Type the current password (the default password is

Asante) and press return.

The Configuration menu appears.

Segment Control

The AsantéHub 2072 and NetStacker hub provide two discrete network segment interconnections. That is, any AsantéHub 2072 or NetStacker module, including the AH 2072 NMM, can be connected to Segment 1, Segment 2, or neither segment (isolated).

Segment connection assignment for any module can be done through NMM front panel controls or with AsantéView software.

The NMM has two push-button Segment Controls: the Select Slot and Change Segment buttons, which are located on the right of the front panel. Figure 26 shows the location of these buttons.

You may want to divide your network into two separate, distinct backbones, so that traffic from one network does not interfere with traffic or cause traffic congestion on your other network. For example, in a campus-like environment, you may have two completely different networks (two separate backbones) independent of each other.

Continuing with this example, Network A is an administration/faculty network and Network B is a student-operated network. The student network is primarily used for network lab testing, which can be highly vulnerable to periodic downtime.

However, Network A, which is solely operated by university administration and faculty members, primarily uses its network for record keeping and administrative tasks, and therefore, must operate smoothly without any unnecessary student interference from Network B. To keep the two segments isolated from each other, the network manager can use Segment Control.

Figure 27 Selecting a Slot for Segment Change

To ensure that you maintain network management capabilities, you must make sure that your

AsantéView Management Station (AMS), which is running AsantéView management software, is on the same segment as the NMM. (Segment 1 is the default setting.)

To manually select a module for segment change, complete the following steps.

1 Press the Select Slot button.

If the NMM is set to Segment 1, pressing the Select

Slot Button causes the Segment 1 LED to flash. If the

NMM is set to Segment 2, pressing the Select Slot Button causes the Segment 2 LED to flash. If the NMM is isolated (set to neither segment), pressing the Select

Slot Button causes both segment LEDs of the NMM module (Seg 1 and Seg 2) to flash.

2 Continue pressing the Select Slot button until you have chosen your specified slot. The Segment LED for the specified slot begins flashing.

Page 39

AsantéHub 2072 Network Management Module Installation Guide

3 Press the Change Segment button repeatedly until you have chosen the segment you want: Seg 1, Seg 2, or neither.

4 When you have chosen your segment, press both the

Select Slot and Change Segment buttons together. In approximately two to three seconds, the change is made and the specified segment’s LED lights; the unspecified segment’s LED darkens. (See Figure 27 on page 39.)

Network statistics cannot be collected if a module is isolated from both segments.

Isolating Modules from the Network

To isolate (remove) a particular module from the network, press both the Select Slot and Change Segment buttons simultaneously.

Both segment LEDs for the selected slot remain lit. Table 4 identifies the LED states for both segments while you are cycling through the process (changing from one segment to another).

Table 4 Segment LED States

LED State Meaning

Seg 1 LED, On

Seg 2 LED, On

Seg 1 & Seg 2, Off

This particular slot is connected to Seg 1.

This particular slot is connected to Seg 2.

There is no segment connection.

If your AsantéView Management Station (AMS) is on one segment, and you change the NMM to the other segment, you will not be able to communicate with the NMM (provided a bridge does not exist between the two segments). You lose your

Telnet connection and SNMP capabilities.

You can reestablish communication with the module by changing the segment using the Select

Slot and Change Segment buttons on the hub, by connecting your AMS to the other segment, or by using AsantéView Out-of-Band.
