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.

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.

Intel Cascade Cable

(product code EE110CC)

Managing multiple hubs

To manage multiple hubs, you must stack them using Intel Cascade Cables.

100 Mbps

10 Mbps

Connecting hubs with Intel Cascade Cables allows you to manage both 10 and 100 Mbps hubs with a sin

le 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.

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).

The entire hub is called the chassis.

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.

10 Mbps

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.

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.

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.

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.
