Chapter 1 Network monitoring The Ethernet Switches 460 and 470 provide features that allow you to monitor your network, display switch statistics, and log system events. This chapter discusses the following topics: • "System Log" (page 15) • "Port mirroring" (page 17) • "Port Statistics screen" (page 25) System Log System Log messages operate as follows: • Non-volatile memory messages are retrievable after a system reset. • Messages can be viewed while the system is operational.
Chapter 1 Network monitoring è Choose Display System Log (or type y) from the main menu. Figure 1 System Log screen Displaying most recent log entry first This option allows you to view the system log with the most recent entry displayed first; the rest of the log entries are listed in reverse chronological order. Table 1 "System Log screen fields" (page 16) describes the System Log screen fields.
Port mirroring 17 Field Description Display configuration complete? This field allows you to determine whether the configuration information received from non-volatile or dynamic memory (depending on what is selected in the Display Messages From field) is complete. Use the spacebar to toggle between the options. Default No Range No, Yes Clear Messages From This field allows you to clear the information messages from dynamic or non-volatile memory or both.
Chapter 1 Network monitoring Port-based mirroring configuration Figure 2 "Port-based mirroring configuration example" (page 18) shows an example of a port-based mirroring configuration where port 23 is designated as the monitor port for ports 24 and 25 of Switch S1. Although this example shows ports 24 and 25 monitored by the monitor port (port 23), any of the trunk members of T1 and T2 can also be monitored. In this example, port X and port Y are members of Trunk T1 and Trunk T2.
Port mirroring 19 • Monitor all traffic received by port X or transmitted by port Y. • Monitor all traffic received by port X (destined to port Y) and then transmitted by port Y. • Monitor all traffic received/transmitted by port X and transmitted/received by port Y (conversations between port X and port Y).
Chapter 1 Network monitoring Figure 4 Address-based mirroring configuration example In this configuration, the designated monitor port (port 23) can be set to monitor traffic in any of the following modes: • Monitor all traffic transmitted from address A to any address. • Monitor all traffic received by address A from any address. • Monitor all traffic received by or transmitted by address A. • Monitor all traffic transmitted by address A to address B.
Port mirroring 21 Note: The screen data displayed at the bottom of the screen changes to show the new currently active port mirroring configuration after you press Enter. The Monitoring Mode field [ Address A - > Address B ] indicates that all traffic transmitted by address A to address B is monitored by the StackProbe attached to Monitor Port 23. Note: When you enter MAC addresses in this screen, they are also displayed in the MAC Address Table screen EAPOL.
Chapter 1 Network monitoring • VLAN configuration settings for any ports configured for port-based mirroring cannot be changed. Use the Port Mirroring Configuration screen to disable port mirroring (or reconfigure the port mirroring ports), then change the VLAN configuration settings. • For port-based monitoring of traffic, use one of the following modes for monitoring broadcast, IP Multicast, or unknown DA frames: — Monitor all traffic received by port X. — Monitor all traffic transmitted by port X.
Port mirroring 23 Table 2 "Port Mirroring Configuration screen fields" (page 23) describes the Port Mirroring Configuration screen fields. Table 2 Port Mirroring Configuration screen fields Field Description Monitoring Mode Allows a user to select any one of six port-based monitoring modes or any one of five address-based monitoring modes (see Table 3 "Monitoring modes" (page 24)).
Chapter 1 Network monitoring Field Description Address A Indicates the MAC addresses that is monitored by the designated port monitor when one of the address-based monitoring modes is selected. This port is monitored according to the value of Address A in the selected Monitoring Mode field (see Table 3 "Monitoring modes" (page 24)).
Port Statistics screen 25 Field Description <-> Port X and Port Y <-> Monitor all traffic received/transmitted by Port X and received/transmitted by Port Y. Note: Do not use this mode for broadcast or multicast traffic Address-based: Disabled Default value for this feature. Address A -> any Address Monitor all traffic transmitted from Address A to any address. any Address -> Address A Monitor all traffic received by Address A from any address.

Chapter 6 Configuring RMON using Device Manager The Remote Network Monitoring (RMON) MIB is an interface between the RMON agent on an Ethernet Switch and an RMON management application, such as the Device Manager. The RMON MIB defines objects that are suitable for the management of any type of network, but some groups are targeted for Ethernet networks in particular. The RMON agent continuously collects statistics and proactively monitors switch performance.
Chapter 6 Configuring RMON using Device Manager RMON history Ethernet history records periodic statistical samples from a network. A sample is called a history and is gathered in time intervals referred to as buckets. Histories establish a time-dependent method for gathering RMON statistics on a port. The default values for history are: • Buckets are gathered at 30-minute intervals. • Number of buckets gathered is 50. Both the time interval and the number of buckets is configurable.
Working with RMON information 93 Figure 34 RmonControl, Insert History dialog box 3 Select the port from the port list or type the port number. 4 Set the number of buckets. The default is 50. 5 Set the interval. The default is 1800 seconds. 6 Type the owner (the network management system that created this entry). Click Insert. —End— Table 41 "History tab fields" (page 93) describes the History tab of the RmonControl dialog box.
Chapter 6 Configuring RMON using Device Manager Field Description Interval The interval in seconds over which the data is sampled for each bucket in the part of the media-specific table associated with this entry. You can set this interval to any number of seconds between 1 and 3600 (1 hour). Because the counters in a bucket can overflow at their maximum value with no indication, note the possibility of overflow in any of the associated counters.
Working with RMON information 95 Figure 35 Rmon History statistics Table 42 "Rmon History statistics tab fields" (page 95) describes the Rmon History statistics tab fields. Table 42 Rmon History statistics tab fields Field Description SampleIndex Indicates the sample number. As history samples are taken, they are assigned greater sample numbers. Utilization Estimates the percentage of link capacity used during the sampling interval.

RMON Alarms 99 rising value, the alarm fires as a rising event. During the first interval that the data drops below the falling value, the alarm fires as a falling event (Figure 39 "How alarms fire" (page 99)). Figure 39 How alarms fire It is important to note that the alarm fires during the first interval in which the sample goes out of range. No additional events are generated for that threshold until the opposite threshold is crossed.
Chapter 6 Configuring RMON using Device Manager to drop to zero), the falling alarm cannot fire, because the baseline traffic is always greater than the value of the falling threshold. By definition, the failure of the falling alarm to fire prevents the rising alarm from firing a second time. Figure 40 Alarm example -- threshold less than 260 Creating alarms When you create an alarm, you select a variable from the variable list and a port, or other switch component, to which it is connected.
RMON Alarms 101 intended only to demonstrate how alarms fire; it is not a useful alarm. Because of the high frequency, delete this alarm and replace it with a practical setting. To create an alarm to receive statistics and history using default values: Step Action 1 Do one of the following: • From the Device Manager main menu, choose Rmon >Alarm Manager. • On the toolbar, click the Alarm Manager button. The Alarm Manager dialog box opens (Figure 41 "Alarm Manager dialog box" (page 101)).
Chapter 6 Configuring RMON using Device Manager Figure 42 Alarm variable list Alarm variables are in three formats, depending on the type: • A chassis alarm ends in x where the x index is hard-coded. No further information is required. • A card, spanning tree group (STG) or EtherStat alarm ends with a dot (.). You must enter a card number, STG ID, IP address, or EtherStat information. • A port alarm ends with no dot or index and requires using the port shortcut menu.
