Chapter 1 Introduction How to use this guide; related guides; software conventions; getting help Welcome to the GatorMIM CS and GatorStar GX-M User’s Guide. We have designed this guide to serve as a reference for using NetSight Element Manager for the GatorMIM CS and the GatorStar GX-M. The GatorMIM CS and GatorStar GX-M are LocalTalk to Ethernet routers—based on Cayman Systems’ GatorBOX-CS technology—which are integrated for use in the MMAC series of intelligent hubs.
Introduction Using the GatorMIM CS/GatorStar GX-M User’s Guide Each chapter in this guide describes one major functionality or a collection of several smaller functionalities of the GatorMIM CS and the GatorStar GX-M. This guide contains information about software functions which are accessed directly from the device icon. NOTE The GatorStar GX-M and the GatorMIM CS will be jointly referred to as the Gator Module throughout much of this manual.
Introduction Software Conventions Your NetSight Element Manager’s device user interface contains a number of elements common to most windows and which operate the same regardless of the window in which they appear. A brief description of some of the most common elements appears below. The information provided here is not repeated in the descriptions of specific windows and/or functions.
Introduction • Double-clicking means to position the mouse pointer over the indicated target, then press and release the mouse button two times in rapid succession. This is commonly used to activate an object’s default operation, such as opening a window from an icon. Note that there is a distinction made between “click twice” and “double-click,” since “click twice” implies a slower motion.
Introduction MAC Address Displays the manufacturer-set MAC address of the device interface. This address is factory-set and cannot be altered. Using Window Buttons The Cancel button that appears at the bottom of most windows allows you to exit a window and terminate any unsaved changes you have made. You may also have to use this button to close a window after you have made any necessary changes and set them by clicking on an OK, Set, or Apply button.
Introduction NOTE All of the online help windows use the standard Microsoft Windows help facility. If you are unfamiliar with this feature of Windows, you can select Help from the Windows Start menu, or Help —> How to Use Help from the primary NetSight Element Manager window. Accessing On-line Documentation The complete suite of documents available for NetSight Element Manager can be accessed via a menu option available from the primary window menu bar: Help—>Online Documents.
Introduction Send your questions, comments, and suggestions regarding NetSight documentation to NetSight Technical Communications via the following e-mail address: Netsight_docs@enterasys.com To locate product specific information, refer to the Enterasys Web site: http://www.enterasys.com NOTE Getting Help For the highest firmware versions successfully tested with NetSight Element Manager 2.2.1, refer to the Readme file available from the NetSight Element Manager 2.2.1 program group.
Introduction 1-8 Getting Help
Chapter 2 The Gator Module View Information displayed in the Module View window; Chassis Manager window; enabling and disabling ports The Gator Module View window is the main screen that immediately informs you of the current configuration of the ports on your Gator Module. Because the Gator Module functions as a stand-alone IMIM (Intelligent Media Interface Module), other MIMs in the MMAC chassis will not be visible.
The Gator Module View 1. In any map, list, or tree view, click the right mouse button to select the Gator Module you wish to manage, and on the resulting menu, click Manage. Viewing Device Information The Gator Module View window (Figure 2-2) provides a graphic representation of the Gator Module, including a color-coded port display which immediately informs you of the current configuration and status of the ports on the module. Figure 2-2.
The Gator Module View NOTE Up to 24 ports can be displayed simultaneously on a module. If a module has a higher port density than 24 ports, Up and Down arrows will appear at the top and bottom of the port stack so that you can scroll through the remaining ports. Front Panel Information The section below the main port display provides the following device information: Connection Status This color-coded icon indicates the current state of communication between NetSight Element Manager and the Gator Module.
The Gator Module View Menu Structure By clicking on various areas of the Gator Module’s Module View display, you can access menus with device-, board-, and port-level options, as well as utility applications which apply to the device as a whole. Figure 2-3 displays the menu structure and indicates how to use the mouse to access the various menus. Device menu for the GatorMIM CS Port menu is available for the GatorMIM CS only Device menu for the GatorStar GX-M Figure 2-3.
The Gator Module View • I/F Summary displays statistics for the traffic processed by each network interface on your device; seeViewing I/F Summary Information, page 2-8, for details. • Exit closes the Gator Module View window.
The Gator Module View Gator Module Port Status Display The Port Status display varies for each module type. The status conditions for the GatorMIM CS are: ON (Green) The port is on-line and forwarding packets across the Gator Module from one network segment to another. OFF (Red) The port has been disabled by management; no traffic can be received or forwarded on this port. ? (Blue) The status of ports cannot be determined by the software.
The Gator Module View The Gator Module does not support MIB Components. The MIBs which provide the Gator Module’s functionality — both proprietary MIBs and IETF RFCs — are listed here Figure 2-4. Chassis Manager Window Viewing Hardware Types Menu options at several levels provide specific information about the physical characteristics of the Gator Module and its ports. Viewing the Device Type The Device Type displays a description of the device being modeled. 1.
The Gator Module View Figure 2-6. Sample Module Type Window Viewing the Port Type You can view a brief description of the ports on your Gator MIM CS via the Port menu; this option is not available for Gator Star GX-M ports. 1. Click on the appropriate Port to display the Port menu. 2. Click Description. The Interface Description window, Figure 2-7, opens. Figure 2-7.
The Gator Module View Figure 2-8. I/F Summary Window The I/F Summary window provides a variety of descriptive information about each interface on your device, as well as statistics which display each interface’s performance. 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 (e.g., ethernet-csmacd). Description A text description of the interface.
The Gator Module View 1. In the right-most menu field, click to select the unit in which you wish to display the selected statistic: Load, Raw Counts, or Rate. NOTE Bar graphs are only available when Load is the selected base unit; if you select Raw Counts or Rate, the Bar Graph column will be removed from the interface display. 2. Once you have selected the base unit, click in the left-most field to specify the statistic you would like to display.
The Gator Module View Out Errors Outbound packets that could not be transmitted by the device interface because they contained errors. Load The number of bytes processed by the indicated interface during the last poll interval in comparison to the theoretical maximum load for that interface type (10 Mbps for standard Ethernet). Load is further defined by the following parameters: In Octets The number of bytes received by this interface, expressed as a percentage of the theoretical maximum load.
The Gator Module View Figure 2-9. Interface Detail Window Three informational fields appear in the upper portion of the window: Description Displays the interface description for the currently selected interface. Address Displays the MAC (physical) address of the selected interface. Type Displays the interface type of the selected port (e.g., ethernet-csmacd). The lower portion of the window provides the following transmit and receive statistics.
The Gator Module View Discarded Displays the number of packets which were discarded even though they contained no errors that would prevent transmission. Good packets are typically discarded to free up buffer space when the network becomes very busy; if this is occurring routinely, it usually means that network traffic is overwhelming the device. To solve this problem, you may need to re-configure your bridging parameters, or perhaps re-configure your network to add additional bridges or switches.
The Gator Module View To calculate the percentage of outbound packets that were discarded: Transmit Discards /Packets Transmitted NOTE The Interface Statistics window does not offer Disable or Test options. These options are available in the Interface Group window, which can be accessed via the System Group window (select System Group from the Device menu). Refer to your Generic SNMP User’s Guide for more information on the System Group and Interface Group windows.
Chapter 3 LocalTalk and GatorStar Statistics LocalTalk Statistics window; Total Repeater Statistics window Viewing LocalTalk Statistics The LocalTalk Statistics window (Figure 3-1) displays accumulated statistics and error breakdowns at the device level for the LocalTalk side of the Gator module. Statistics are displayed in numeric form and in graphic form as a pie chart. 1. Select Device—>LocalTalk Statistics in the Module View menu bar. The LocalTalk Statistics window, as shown in, Figure 3-1, opens.
LocalTalk and GatorStar Statistics The following packet and error statistics appear within the LocalTalk Statistics window: Packets Fields The Packet Fields display general performance information on the LocalTalk interface are as follows: In Packets The total number of good packets received by the LocalTalk interface. Out Packets The total number of packets transmitted from the LocalTalk interface.
LocalTalk and GatorStar Statistics Random CTS Errors The total number of times the LocalTalk interface received a lapCTS packet that was not solicited by a lapRTS packet. FCS Errors The total number of times the LocalTalk interface received a packet with an FCS (Frame Check Sequence) error. When a packet is transmitted, the MAC layer of the transmitting device computes an FCS value based on the contents of the packet, and appends that value to the packet.
LocalTalk and GatorStar Statistics The following fields appear within the Gator Total Repeater Statistics window: Packets Fields Total Packets Error Fields Total Jabbers 3-4 The total number of packets processed by the device since the last reset. Total Packets are color-coded green. The total number of packets since the last reset that were oversized (greater than 1518 bytes — a Giant packet), and had either a non-integral number of bytes (alignment error) or a bad frame check sequence (CRC error).
