The Asanté 2072 Network Management Module (NMM) provides
overall network management for the AsantéHub
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
tor network traffic, and set alarm thresholds. Figure 1 shows an
example of the NMM front panel.

Segment Control allows you to monitor and control both segments of the AsantéHub
The module’s RS232 port and its AsantéV iew Manag ement 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. Y ou 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 micr ocode upgrades from an AsantéV ie w 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.

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 AsantéView 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
The
Boot File Name referred to in the menu is the configura-
tion file residing in the AsantéView

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
edly cycles through the available g roups. Pressing
N (uppercase N) repeat-
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
cycles back and forth through the available groups. Pressing
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.

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, prob-
lem 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
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.
Asante.
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.

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

Segment Control The AsantéHub 2072 and NetStacker hub provide two discrete
network segment interconnections. That is, any AsantéHub
or NetStacker module, including the AH
nected 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 networ ks (tw o separate bac kbones) 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.
Page 38
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.

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.

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

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).
Press the Change Segment button repeatedl y until you
have chosen the segment you want: Seg 1, Seg 2, or
neither.
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 mod-
ule is isolated from both segments.

▲ 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
