Page 73: Automatic Broadcast Control (Abc)
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.
Page 74 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.
Page 75: Internet Group Management Protocol (Igmp)
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.

Page 91: Reading The Traffic Information Gauges
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.
Page 92: Selecting Segment Groups And Segments
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.
Page 93 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.

The priorities are defined as follows: Low: Implementing this recommendation will result in a small reduction in network utilization.
Page 116: Recommendation Details Section
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.
Page 117 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.
Page 118: Add Or Upgrade 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.
Page 122 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.

Page 126: Traffic Data Collector Performance
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.

Page 128: Segments Excluded From Analysis
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.

Page 131: Basic Operation
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.

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.
