Chapter 2 The FN100 Chassis View About the Chassis View window; the Chassis Manager window; Hub management functions The FN100 Chassis View window is the main screen that immediately informs you of the current condition of individual ports on your switch via a graphical display. The Chassis View window also serves as a single point of access to all other FN100 windows and screens, which are discussed at length in the following chapters.
The FN100 Chassis View Viewing Chassis Information The FN100 Chassis View window (Figure 2-1) provides a graphic representation of the FN100, including a color-coded port display which immediately informs you of the current configuration and status of the switch and its ports. On an 8-port FN100, the network management port is represented as port 9. On a 16-port FN100, the network management port will be represented as port 17. Figure 2-1.
The FN100 Chassis View • Green indicates the FN100 is responding to device polls (valid connection). • Magenta indicates that the FN100 is in a temporary stand-by mode while it responds to a physical change in the hub; note that port menus are inactive during this stand-by state. • Blue indicates an unknown contact status – polling has not yet been established with the FN100.
The FN100 Chassis View Menu Structure By clicking on various areas of the FN100 Chassis View display, you can access menus with device- and port-level options, as well as utility applications which apply to the device. The following illustration displays the menu structure and indicates how to use the mouse to access the various menus: Figure 2-2.
The FN100 Chassis View • Virtual Switching..., which launches the FN100 Virtual Switching window, allowing you to refine your network and control bandwidth usage by assigning the FN100’s ports to any of four available virtual switches. See Chapter 3, FN100 Virtual Switching, for details. • Port Trunking..., which allows you to use the FN100 Port Trunking window to create trunk groups, letting you increase aggregate bandwidth when two or more switches are connected.
The FN100 Chassis View The Utilities Menu From the Utilities menu you can select: NOTE • MIB Tools, provides direct access to the FN100’s MIB information. This selection is also available from the Tools menu at the top of the NetSight Element Manager’s main window. Refer to the Tools Guide for more information on the MIB Tools utility. • RMON, for launching the Remote Network Monitoring application. RMON is described in its own User’s Guide.
The FN100 Chassis View • Enable/Disable, which administratively turns the selected bridging port on or off; see Viewing I/F Summary Information on page 2-13 for more information. The FN100 Port Status Displays When you open the Chassis View window, each port on the FN100 will display its Admin status (defined below); to change this status display, select one of the options on the Port Status menu, as described in the following sections. Selecting a Port Status View To change the status of your ports: 1.
The FN100 Chassis View • BRK (broken) when the physical interface has malfunctioned. • UNK (unknown) if the interface’s status cannot be determined. If you have selected Bridge Mapping, the port status boxes will display the bridge interface index numbers assigned to each interface (which may or may not match the ifIndex values displayed via the I/F Mapping option described below). If you have selected the Admin status mode, a port is considered: • ON if the port has been enabled by management.
The FN100 Chassis View I/F Type If you choose the I/F Type mode, the port text boxes will display the port type (e.g., Eth, PPP) of each port, as determined by the port’s MIB II ifType value. Port Status Color Codes The Bridge port display mode incorporates the following color-coding scheme: green = FWD, blue = DIS, magenta = LIS/LRN, orange = BLK, red = BRK, and gray = UNK. The Admin and Operator port display modes use the following color-coding scheme: green = ON, red = OFF.
The FN100 Chassis View The MIBs which provide the FN100’s functionality — both proprietary MIBs and IETF RFCs — are listed here. MIB Components are listed here; remember, there’s no one-to-one correspondence between MIBs and MIB Components. Figure 2-3. Chassis Manager Window Viewing Hardware Types In addition to the graphical displays described above, menu options available at several levels provide specific information about the physical characteristics of the FN100 and its ports.
The FN100 Chassis View Figure 2-5. Port Description Windows Managing the Hub In addition to the performance and configuration information described in the preceding sections, the Chassis View also provides you with the tools available to configure your device and keep it operating properly. Hub management for the FN100 is comprised of locating source addresses, viewing interface statistics and CSMACD statistics, as well as administratively enabling and disabling the ports.
The FN100 Chassis View Figure 2-6. Device Find Source Address Window The Device Find Source Address window displays the following information: Component Displays the type of interface through which the specified MAC address is communicating. This field will report Bridge. Port Instance Displays the bridge port index number on which the specified MAC address was found. To use the Device Find Source Address window: 1.
The FN100 Chassis View If the specified MAC address is located, a list of the interface(s) through which the given address is communicating displays in the list box. A status message at the bottom of the window will display the number of interfaces through which the given MAC address is communicating. If the specified MAC address cannot be found, a “Source Address not found” message displays. NOTE If the MAC address is entered in an incorrect format, an “Invalid MAC Address.
The FN100 Chassis View The following descriptive information is provided for each interface: UpTime The UpTime field lists the amount of time, in a days, hh:mm:ss format, that the device has been running since the last start-up. Index The index value assigned to each interface on the device. Type The type of the interface, distinguished by the physical/link protocol(s) running immediately below the network layer.
The FN100 Chassis View After you select a new display mode, the statistics (and graphs, where applicable) will refresh to reflect the current choice, as described below. Raw Counts The total count of network traffic received or transmitted on the indicated interface since device counters were last reset. Raw counts are provided for the following parameters: In Octets Octets received on the interface, including framing characters.
The FN100 Chassis View Out Octets The number of bytes transmitted by this interface, expressed as a percentage of the theoretical maximum load. When you select this option, a Bar Graph field will be added to the interface display area; this field is only available when Load is the selected base unit. Rate The count for the selected statistic during the last poll interval. The available parameters are the same as those provided for Raw Counts.
The FN100 Chassis View TIP You can also access this information via the I/F Statistics option available on the individual port menus. Three informational fields appear in the upper portion of the window: Description Displays the interface description for the currently selected interface: Ethernet or Fast Ethernet. Address Displays the MAC (physical) address of the selected interface. Type Displays the interface type of the selected port: ethernet-csmacd.
The FN100 Chassis View Unknown Protocol (Received only) Displays the number of packets received which were discarded because they were created under an unknown or unsupported protocol. Packets Received (Received only) Displays the number of packets received by the selected interface. Transmit Queue Size (Transmit only) Displays the number of packets currently queued for transmission from this interface.
The FN100 Chassis View Viewing CSMACD Statistics The CSCMACD Statistics Windows display statistics for each bridging interface on your FN100. Receive errors, transmission errors, and collision errors are displayed in this window. Three color-coded pie charts allow you to view the breakdowns of each statistics group. To access the CSMACD Statistics window from the Chassis View window: 1. Click on the desired port to reveal the Port menu. 2. Choose CSMACD Stats....
The FN100 Chassis View a MAC layer packet formation problem, or from a cabling problem that is corrupting or losing data.

FCS, or Frame Check Sequence, errors occur when packets are somehow damaged on transit.
The FN100 Chassis View Internal MAC The number of frames for which transmission fails due to an internal MAC sublayer transmit error. This error is only counted in this window if there have not been corresponding Late Collisions, Excessive Collisions, or Carrier Sense Errors. Transmit Errors The total of transmission errors of all types that occurred while the selected interface was attempting to transmit frames.
The FN100 Chassis View To enable or disable a bridge port: 1. Click on the desired Port index. The Port menu will appear. 2. Click on Enable to enable the port, or Disable to disable the port. You will get a confirmation window asking if you’re “sure you want to Enable/Disable this Bridge Port.” Click OK and your port will now be enabled or disabled.
Chapter 3 FN100 Virtual Switching FN100 virtual switches; performing virtual switching The FN100 Virtual Switching window (Figure 3-1) allows you to refine your network and control bandwidth usage by assigning the FN100’s ports to any of four available virtual switches. This feature can be used to logically group network users and control the amount and type of traffic that is propagated beyond each logical group.
FN100 Virtual Switching Figure 3-1. The Virtual Switching Window The Virtual Switching window features a column of four radio buttons (one button for each virtual switch) for each of the FN100’s ports. The port indices are listed atop each column.
FN100 Virtual Switching Defining a Default Switch By defining a default switch setting, you decide which of the FN100’s four virtual switches will be recognized by Spanning Tree and reflected in the FN100 Bridge Status window. When you change the default switch, only those ports which are assigned to the selected default switch will be correctly displayed in the Bridge Status window. All other ports will return an UNKNOWN bridge state. To define a default switch for your FN100: 1.

Chapter 4 Using FN100 Trunking The Trunking Table window; enabling and disabling trunking Trunking, an extension of the 802.1D Spanning Tree protocol, allows you to increase aggregate bandwidth when two or more switches are connected. A single 10/100BASE-T connection between switches yields 10 or 100 Mbps of bandwidth, depending on the speed of the ports used for the connection.
Using FN100 Trunking To display the Port Trunking window from the FN100 Chassis View: 1. Click to display the Device menu. 2. Drag down to Port Trunking..., and release. The Port Trunking window, Figure 4-1, will appear. Figure 4-1.
Using FN100 Trunking the FN100’s trunking PDUs are being successfully received at the other end of the link. • joined — trunking is enabled, the trunking protocol has established a good trunk connection, and the port is actively participating in the trunk group.
Using FN100 Trunking • 5 — standby — the trunk group is filled to capacity with other ports; this port is now a hot standby. If another port leaves the trunk group, this port will then be included in the group. • 6 — too-many-groups — the maximum number of groups (4) has been reached, and a new group cannot be added. This port will not be used until the condition clears. • 7 — no-ack (no acknowledgment) — this port has not received a valid trunking packet, and the trunking protocol will restart.
Using FN100 Trunking Enabling and Disabling Trunking To enable trunking for your FN100 ports using the Port Trunking window: 1. In the port selection list, click on an entry representing a port for which you would like to enable trunking. 2. Click on Enable. The trunking table will update to include the new trunking selection. 3. Repeat steps 1 and 2 for each port for which you want to enable trunking. 802.

Chapter 5 Workgroup Configuration Workgroups explained; adding and deleting workgroups from this window The FN100’s Virtual Workgroups window allows you to restrict multicast traffic from being propagated through every bridge port on your device. This optimizes bandwidth by limiting the subnet broadcast traffic to only those ports that require the traffic.
Workgroup Configuration Figure 5-1. Virtual Workgroups Window You can view and modify existing work groups as well as configure new work groups from this window. The Workgroup Table at the top of the window lists each existing work group along with its configuration information. The Add/Modify section of this window allows you to set-up the parameters of your work group, including Name and Type.
Workgroup Configuration 3. Choose the Type of workgroup being created or modified. This determines whether ports in this workgroup will forward only multicast packets, only unicast packets, or both multicast and unicast packets. The following are your possibilities: • All — ports in this workgroup will forward both unicast and multicast packets. • Multicast — ports in this workgroup will forward only multicast packets. • Unicast — ports in this workgroup will forward only unicast packets. 4.
