Check the cable routing and reroute any cabling which may be affected by other noise sources.

Late Events Shows the number of frames for which a collision was detected after the valid packet minimum time. A late event can occur if you have a Local Area Network that is longer than Ethernet standards allow (for example, more than four repeaters in series or excessively long segments).

Very Long Events Shows the number of frames that caused Jabber Lock Up protection to operate. Jabber Lock Up is when a transceiver turns itself off, if it starts uncontrollably transmitting. Isolate the source and change the transceiver or network adapter in the device to see if this eliminates the problem.

Rate Mismatch Shows the number of frames whose timing was outside the permitted range. This may indicate a non-compliant device on your network. Isolate the source and change the transceiver or network adapter in the device to see if this eliminates the problem.

The values shown in the Network Errors graph are per poll period, not per second. To change the poll period, see “Accessing the Hub” on page 4-6.

Configuring a Port

Quick Config Manager allows you to configure how individual ports operate, enabling you to introduce some simple security to your network. The hub provides more complete security which you can configure for the ports, see “Hub Security” on page 4-28.

For each port you can configure it:

■To be enabled or disabled.

■To send traps (messages) to an IP/IPX-based network management application if the port changes state, for example, the port partitions or its connection is lost.

■To learn the MAC address (hardware address) of the device connected to it.

Enabling a port allows it to repeat information to and from the network. Disabling a port prevents it from repeating information onto the network. We recommend that you disable any unused ports to prevent unauthorized use.
