Quick Start
1. Turn off the power. Unscrew and remove the panel from an expansion slot
on the Express 10/100 Stackable Hub.
Expansion slots: Use either slot. They are
identical.

Overview of Hub
Management
Hubs themselves are rarely the cause of problems on the network.
However, since hubs are the center point for many devices on the
network, it’s a good place to start looking for problems.
1
There are four categories of management tasks:
•
Configuring the hub or stack of hubs. This includes setting the IP
configuration, naming the hubs, and disabling individual ports.
•
Monitoring traffic. This helps to plan network expansion or make
segmenting decisions.
•
•
Finding malfunctioning devices such as LAN adapters in PCs.
Finding wiring problems between an attached device and the hub.
There are several methods for managing hubs. You can use any
combination.
•
Manage with the onboard LCD or Console Manager. This method
works best for initial setup or when the network goes down and
you can’t access the hub with an SNMP application.
•
Manage with Intel Device View for Web or LANDesk® Network
Manager. These SNMP applications are tailored for Intel products
and show a graphical representation of the hub.
•
Manage with any other SNMP-compliant application. If you
already use an SNMP application, you can manage hubs by
compiling the hub’s MIB files into that application. File locations
are listed on page 51.

Managing multiple hubs
To manage multiple hubs, you must stack them using Intel Cascade
Cables.
100 Mbps
100 Mbps
10 Mbps
10 Mbps
Intel Cascade Cable
(product code EE110CC)
Connecting hubs with Intel Cascade Cables
allows you to manage both 10 and 100 Mbps
hubs with a single Management Module.
Hub numbering
Once connected with Intel Cascade Cables, the Management Module
numbers hubs from top to bottom, regardless of the placement of the
Management Module.

Collision domain assignments
All hubs running at the same speed in the stack belong to the same
collision domain. In the example below, all devices (PCs, print
servers, and so on) connected to hubs 1 and 2 share 100 Mbps of
bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of
bandwidth.

The two collision domains don’t pass traffic to each other without
optional bridging equipment (see the Intel Express 10/100 Stackable
Hub User Guide that came with the hub for more information on
bridging options).
MIB identification
If you use a MIB browser, you can configure or view statistics for the
hub at three levels – by hub (chassis), module, or port. The MIB file
locations are listed on page 51.

Wrong Speed
Utilization:The percentage of Ethernet bandwidth (10 or 100
Mbps) being used by devices attached to the hubs. All hubs in the
stack running at the same speed are in the same collision domain and
share either 10 or 100 Mbps of bandwidth.
Collisions:The number of collisions detected. Collisions are
normal in an Ethernet network. They tend to rise as network
utilization rises.
Frames:The number of frames detected without errors. Includes
unicast, broadcast, and multicast frames. It does not include frames
received with frames too long, runt, FCS, or alignment errors.
Octets:The number of octets (bytes) contained in frames received
that had no errors. This includes octets in unicast, broadcast, and
multicast frames. It also includes octets after the start frame delimiter
up to FCS, but not including FCS octets.
NOTE
Since frames vary in length,
it’s best to look at the octet
count to see how much traffic
is passing through the hubs.
FCS errors:The number of frames detected that are free of partial
octets and do not pass the FCS check. Usually caused by adapter
underrun (when the adapter can’t get enough PCI bandwidth). FCS
errors do not necessarily indicate that data has been lost.
Alignment errors:The number of frames detected that contain
partial octets and do not pass the FCS check. This is usually caused
by a faulty adapter or poor quality cabling.
29
Download from Www.Somanuals.com. All Manuals Search And Download.
Frames too long:The number of frames detected that exceed the
maximum permitted frame size of 1518 octets.
Short events:The number of fragments detected with
ActivityDuration less than ShortEventMaxTime (greater than 74 bit
times and less than 82 bit times). Usually indicates a network
topology problem, such as connecting two Express hubs running at
100 Mbps with UTP cable (instead of Intel Cascade Cables in a
stack) or using cables longer than 100 meters.
Late events:The number of collisions detected after the
allowable detection period. Usually indicates a network topology
problem, such as daisy-chaining two Express hubs running at 100
Mbps with UTP cable (instead of Intel Cascade Cables in a stack),
daisy-chaining too many hubs running at 10 Mbps, or using cables
longer than 100 meters.
Very long events:The number of times MAU jabber lockup
protection (MJLP) was detected due to transmission of data that
exceeded five msec. in duration (octet count greater than
maxFramSize). This information can be useful in identifying faulty
devices or ports.
Rate mismatch:A count of the occurrences of out-of-specification
bit rates. This indicates the number of times the FIFO buffer overruns
or underruns due to transmission rate errors. This could indicate an
incorrect FIFO setting on a LAN adapter or a faulty LAN adapter.
Total errors:The total number of errors detected since the port
was last reset. Total errors include FCS errors, alignment errors,
frame too long, short events, late events, very long event, and rate
mismatch errors.
Runts:The number of frames detected that are less than the
minimum permitted frame size and have a good FCS. Runts usually
indicate collision fragments, a normal network event.
Auto partitions:The number of times this port was
automatically partitioned. This condition occurs when 64 consecutive
collisions are detected on the port. These collisions are due to
excessive traffic on the segment, a malfunctioning port, or a
malfunctioning adapter that is jabbering.

Interpreting this screen
It’s best to view utilization coupled with collisions before making any
decisions on the saturation of your network. Generally, Ethernet
saturation starts to occur when the utilization reaches 30% and above.
However, if the collision count is low, you don’t have a saturated
network, but an efficient network.
If both the utilization percentage and the collision count are
consistently high (above 30% for utilization and 50-100 collisions/
second or more), then you have a saturated network and will see poor
performance. The best way to alleviate a saturated network is to
segment the network (have fewer devices share a fixed amount of
bandwidth). You can do this by adding a switch to the network.

Reset all 10 Mbps hubs:Resets all hubs operating at 10 Mbps
in the stack. Think of this as a 10 Mbps collision domain reset. This

NOTE
Resetting a hub causes devices
connected to the hub to tem-
porarily lose their link.
Resetting the Management

links. However, it resets all
statistic counters to zero.
Reset all 100 Mbps hubs:Resets all hubs operating at 100
