Unusual Network Activity

Network activity that exceeds accepted norms may indicate a hub or

network problem. Most of the time, the unusual network activity can be

removed by making sure that your network cabling and network topology

adhere to the standards and requirements described in the HP 100VG

AnyLAN Technology Guide.

Use HP Stack Manager to view the status of the LAN ports and to retrieve

counter values. The counters can provide indications of unusual network

activity. The following table indicates some typical error symptoms and the

most likely causes of those symptoms:

Symptom Cause

High value for the

Data Error Frame

counter in HP Stack

Manager counters

screen

You may be using a bundled cable on a promiscuous port in a

network that is transmitting many group-addressed packets.

Make sure that promiscuous ports, for example the Uplink

port in a hub-to-hub connection, are always connected using

unbundled cable. Note that this cabling error may result in

high Data Error Frame counts on other ports than just the

promiscuous port.

High value for the

Priority Promotions

counter in HP Stack

Manager counters

screen

There may be excessive high-priority traffic on the network.

Make sure that only those end nodes that are authorized to

run in high-priority mode are configured to do so.

High-priority mode is set by configuring the LAN adapter

driver appropriately. You can limit which nodes are allowed

to send high-priority traffic in the Port Settings screen in

HP Stack Manager—set the port configuration to “Normal

Priority Only”.

When using the bridge functionality of the HP J2414B 100VG/ET

SNMP/Bridge module, see the troubleshooting chapter in the HP J2414B

100VG/ET SNMP/Bridge Module Installation and Reference Guide.
