Off: The device will never make any entries in the Alert Log regardless of the severity of the problem.
Group Policies Advanced Switch Features Figure 7-8. Advanced Switch Features Page The problem of broadcast control is addressed in part by the use of two features, Automatic Broadcast Control (ABC) and Internet Group Management Protocol (IGMP). Automatic Broadcast Control (ABC) Automatic Broadcast Control (ABC) is a feature that controls broadcasts through IP/IPX Broadcast Reduction.
Group Policies Advanced Switch Features Routing Information Protocol The switch also intercepts Routing Information Protocol (RIP) and SAP broadcasts and forwards these only to ports where routers and servers have been detected. This also reduces the number of broadcasts on the network. For example, if User A sends out a broadcast message to connect to its server, the request is sent out of all ports on the switch.
A set of queriers and hosts that send and receive data from the same set of sources is a multicast group. The HP switches have a standards-based IGMP implementation. The switches process IGMP packets by learning which of the switch’s interfaces are linked to hosts that are members of multicast groups and multicast routers.

Monitoring Network Traffic Using Traffic Monitor Figure 9-1. Traffic Monitor Main Page The five statistical attributes sampled by Traffic Monitor are: Utilization%: Represents the traffic on the selected network or segment as a percentage of a segment's bandwidth (based on the theoretical maximum for the type of connection) which is currently being utilized.
Monitoring Network Traffic Using Traffic Monitor Multicasts/sec: Represents the number of multicast packets being transmitted per second over the network or segment. Multicast packets are special forms of broadcast packets where copies of the packets are delivered to a subset of all devices on the network. This indicator gives an estimation of the amount of bulk communications which are taking place over the network.
Monitoring Network Traffic Using Traffic Monitor The six tabs across the top of the histogram display the values for the segments for the selected segment group, or for the entire network if “All Segments” is selected in the Segment Groups list box. The Worst Overall tab displays in sorted order left to right the segments that have the most problems in the selected segment group.
Monitoring Network Traffic Using Traffic Monitor segments are trunked. This will not be visible in the Thresholds window. For example, if four ports on a switch are trunked, a 10 Mbps Ethernet segment would now be four times as fast, or 40 Mbps. The threshold values are adjusted automatically to be appropriate for this speed.
Monitoring Network Traffic Using Traffic Monitor To change your threshold settings, select a network type such as Ethernet. The threshold values for the attributes for Ethernet segments are displayed. You can either move the sliders to the left or right to increase or decrease a threshold value, or click on the up/down controls underneath the sliders to fine tune the threshold values.
Monitoring Network Traffic Who Are the Top 5 Talkers? You can keep the Network Meter window anywhere on your PC desktop. It will continue to monitor the status of your network while you use your browser for other tasks. Click on Hide Net Meter to close the window.
Monitoring Network Traffic Who Are the Top 5 Talkers? Figure 9-3. Top 5 Talkers You can display graphs for each of the measured attributes showing: Top Sources (default) Top Destinations Top Connections Top Protocols More than one graph can be displayed at a time, so you can look at the values for multiple attributes for each segment.
Monitoring Network Traffic Who Are the Top 5 Talkers? The colors are in the same order as they appear in the legend, that is, the node with the greatest activity is represented by the color at the bottom of the stacked bar.
Monitoring Network Traffic Who Are the Top 5 Talkers? Others The dark gray portion of the stacked bar represents a summation of all of the other activity that occurred during that minute. There is no additional information contained in this portion of the bar. It can be a useful indicator of an overloaded network when what you see on the graph is large areas of dark gray with no particular user causing a problem.
Traffic Data Collector Settings Starting with HP TopTools for Hubs & Switches version 5, you can collect data from all segments in your network automatically, or collect data from selected ports of a device (manual mode). With manual selection, you can also choose the type of data to be collected, for example, Extended RMON (X-RMON) data or just traffic data.

Planning for Network Growth Reorganize Your Current Equipment Figure 10-4. Summary Report A priority of low, medium or high is given to help you determine the urgency of each recommendation. The priorities are defined as follows: Low: Implementing this recommendation will result in a small reduction in network utilization.
In this situation, the node chris.rose.hp.com communicates most frequently with nodes on another segment. Network utilization can be improved by moving chris.rose.hp.com to the switch segment 10.4.12.10::B3. This is a High Priority recommendation because it will significantly decrease network utilization for switch segment 10.4.12.10::B4.
Planning for Network Growth Reorganize Your Current Equipment Figure 10-6. The traffic pattern after implementing reorganization recommendations The network utilization for switch segment 10.4.12.10::B4 is reduced. The network utilization on switch segment 10.4.12.10::B3 is unchanged. It is recommended that you run this type of report before the Add or Upgrade Equipment report to obtain recommendations for reorganizing your existing equipment.
Planning for Network Growth Add or Upgrade Equipment you must decide if you want the new port to be a member of the VLAN if it isn’t already. For example, if a node is on Port 1 in VLAN A, and you move the node to Port 6, you may want to include Port 6 in VLAN A.

Planning for Network Growth Top Conversations Converting Segments to Desktop Switching If a workgroup has high network utilization and cannot be divided, the Network Performance Advisor may recommend converting the segment’s topology to desktop switching, giving each node a dedicated port.When two nodes need to exchange data, the switch makes a connection with the dedi- cated segments of each node.
Conversations involving nodes that utilize less than .1% of the segment bandwidth are not reported. The segment was not discovered by HP TopTools. Figure 10-9. Top Conversations Page You can use the Top Conversations table to determine who is using the bandwidth when utilization is high for a segment.
HP TopTools provides an inventory list of devices by type of device, for example, a list of all hubs in the network. The HP TopTools inventory list is not organized by segment. Select the Inventory button in the HP TopTools home page.
Planning for Network Growth When There Are No Recommendations When There Are No Recommendations If the Add and Upgrade Equipment Report determines that, based on the historical data for the time period you specified, there are no advantageous ways to optimize the network, the Summary section of the report states that there are no recommendations for changes to your network configuration at this time.

How the Network Performance Advisor Collects Data Keeping the historical data about each conversation on a network requires a large amount of disk space. HP has developed a patented technique for greatly reducing the amount of data collected by using a statistical sampling of network traffic.
Planning for Network Growth How the Network Performance Advisor Collects Data Figure 10-12. The data collector must examine your management station’s capabilities to determine what is appropriate for the resource setting that you select. The capabilities test begins when you click on the Apply Changes button. You will see a screen listing some statistics about the test.
Segments Excluded from Analysis Segments Excluded from Analysis Analysis of network traffic is possible for all segments with HP devices attached to them that have Extended RMON sampling capability, but may be performed for only a subset of the segments. This strategy best utilizes system resources for gathering information about the segments most likely to have traffic flow problems.
This means you can manage available bandwidth so that the most important traffic goes first. As of Summer 1999, HP TopTools for Hubs & Switches can configure a QoS policy in your network for the following HP ProCurve Switches running the C.07.XX (or later) software release:...
Class of Service (CoS) to refer to prioritization configured on an individual switch using the switch's web browser or console interface. At release P.01 of HP TopTools for Hubs & Switches (October, 1999), the HP ProCurve Switches 1600M, 2400M, 2424M, 4000M, and 8000M support QoS in HP TopTools for Hubs &...
Quality of Service Basic Operation Basic Operation HP TopTools QoS operates on two levels as described below. Controlling the priority of outbound packets. ProCurve switch ports have two outbound traffic queues; “normal” priority and “high” priority. High-priority packets leave a port first. Normal-priority packets leave the port after the port’s high-priority queue is emptied.
This feature lists all prioritization policies you have configured using QoS in HP TopTools for Hubs & Switches. The Policy List page provides a listing of all currently configured HP TopTools QoS policies. If the policy list exceeds the length of the list box, use the scroll bar on the right side of the list box to view all policy listings.

Service (ToS) Every IP packet includes a ToS field. This field carries priority settings that are read and used, but not altered by HP ProCurve switches. When an HP TopTools prioritization policy is configured for ToS criteria, the ProCurve switches in the network read the content of the ToS field in packets received from upstream devices and applications and take actions based on whether the policy applies to the packets.
