Chapter 2 Using the TSX-1620 Hub View Navigating through the Hub View, monitoring hub performance; managing the hub The heart of the SPECTRUM Portable Management Application (SPMA) for the TSX-1620 is the Hub View, a graphical interface that gives you access to many of the functions that provide control over the TSX-1620.
Using the TSX-1620 Hub View NOTES The spmarun script invoked first in the above command temporarily sets the environment variables SPMA needs to operate; be sure to use this command any time you launch an application from the command line. This script is automatically invoked when you launch an application from the icon menu or from within the Hub View. If you wish to configure your TSX-1620 in any way, be sure to use a community name with at least Read/Write access.
Using the TSX-1620 Hub View Front Panel Device summary information Figure 2-1. TSX-1620 Hub View Hub View Front Panel In addition to the graphical display of the TSX-1620’s ports, the Hub View gives you device level summary information. The following Front Panel information appears to the right of the port display in the Hub View: Contact Status is a color code that shows the status of the connection between SPMA and the device: Using the Hub View • Green indicates a valid connection.
Using the TSX-1620 Hub View Uptime The time that the device has been running without interruption. The counter resets to 0 days 00:00:00 (days:HH:MM:SS) when one of the following occurs: • Power to the device is cycled. • The device is reset manually. Device Name This field displays the device’s MIB II ifName value. You can set this value using the SNMP MIB2 System Group window, available from the Interface menu.
Using the TSX-1620 Hub View Clicking mouse button 1 on the Quit button closes all Hub View application windows; any open applications which can also be accessed from the command line or from the icon menu will remain open. Using the Mouse in the TSX-1620 Hub View Each of the TSX-1620’s ports will be displayed in the hub view; use the mouse as indicated in the illustration in the following diagram (Figure 2-3) to access Module, Interface/Bridge, and Bridge Port menus and functions.
Using the TSX-1620 Hub View The TSX-1620 Application Displays The TSX-1620 Hub View has two different application display modes: Interface and Bridge. Each mode features different port display forms and offers different menus. The Interface application display is shown by default when the TSX-1620 Hub View is launched. To switch between the Interface and Bridge application displays: 1.
Using the TSX-1620 Hub View The Interface Application Display The Interface application display allows you to view the interfaces according to MIB II status and statistics. The default port display form for the Interface application display is operational status (OperStatus). The Module Menu The Interface Menu Figure 2-5.
Using the TSX-1620 Hub View The Bridge Application Display The Bridge application display allows you to view the bridging interfaces according to Bridge statistics; it also gives you access to the Bridge View and functions, as well as the Bridge Port menu. The default port display form for the Bridge application display is Admin. The Module Menu The Bridge Menu The Bridge Port Menu Figure 2-6.
Using the TSX-1620 Hub View Monitoring Device Performance The information displayed in the Hub View can give you a quick summary of device activity, status, and configuration. SPMA can also provide further details about hub performance via its four-level menu structure.
Using the TSX-1620 Hub View • A status of OFF indicates that the port has been physically disabled, or is broken. • NLK (no link) indicates that the interface’s operational status is determined as “UP”, and it has been administratively enabled, but no physical link state to the port has been detected. • A status of Test indicates that the interface is in some operational or administrative test status, and is unable to pass packets.
Using the TSX-1620 Hub View - • • Out shows the percentage of packets transmitted during the last polling interval to devices connected to the port. This percentage reflects the packets transmitted (determined by the change in the port’s MIB-II ifOutOctets value during the last polling interval, multiplied by 800) compared to the port’s ifSpeed value.
Using the TSX-1620 Hub View - • Non-Unicast (Nucast) shows the percentage of packets transmitted or received by the port during the last polling interval that were multicast packets. - - - NOTE Out shows the percentage of packets that were discarded by the port (determined by the port’s MIB-II ifOutErrors value) during the last polling interval due to hardware transmission errors.
Using the TSX-1620 Hub View Yellow No Link — The interface’s operational status is returned as “UP” and it has been administratively enabled, but no physical link state to the port has been detected. This will not appear for interfaces that do not support link state. Blue Off — The interface is physically disabled (its operational status is returned as “DOWN”), and it had also been administratively disabled prior to entering the physically disabled state.
Using the TSX-1620 Hub View Tp Frames Filtered Displays the percentage of valid frames received by this port that were discarded by the forwarding process. Sr Frames Forwarded Displays the percentage of Source Route bridging frames that have been transmitted to or received from the port’s attached segment that have been forwarded to their destination. Bridge Port Number Displays the port’s bridge port number.

Chapter 3 Using the TSX-1620 Bridge View A brief explanation of bridging methods; a tour of the Bridge Traffic View; using the Detail View; monitoring bridge operation; using the Filtering Database; configuring bridge operating parameters; setting forwarding thresholds and notification options; setting polling parameters; enabling and disabling bridges The SPECTRUM Portable Management Application (SPMA) Bridge View presents a series of windows that describe the TSX-1620 bridge and its bridge interfaces.
Using the TSX-1620 Bridge View Transparent Bridging Transparent bridges are most common in Ethernet networks. Individual Transparent bridges monitor packet traffic on attached network segments to learn their network segment location in terms of which bridge port receives packets originated from a particular station (determined via the packet’s Source Address field). This information gets stored in the bridge’s Filtering Database.
Using the TSX-1620 Bridge View thereby providing route information. The destination station directs replies to each APE packet to the sending station, which, ideally, considers the route traveled by the first reply received to be the most efficient route. The sending station then stores the route information and uses it to send subsequent transmissions to the same station. Alternatively, a sending station may send an STE frame.
Using the TSX-1620 Bridge View NOTES The spmarun script invoked first in the above command temporarily sets the environment variables SPMA needs to operate; be sure to use this command any time you launch an application from the command line. This script is automatically invoked when you launch an application from the icon menu or from within the Bridge TrafficView.
Using the TSX-1620 Bridge View Each box represents a bridge interface. Click button 3 anywhere within a Bridge Port box to display the Port menu. Click button 1 on a bridge interface to select it for display in the Detail View (at least two must be selected to activate the Detail View button). Click on the Device button to display the Device menu The Front Panel shows device-level summary information. Figure 3-1. Mousing Around the Bridge Traffic View To display the Device menu: 1.
Using the TSX-1620 Bridge View Bridge Traffic View Front Panel The right side of the Bridge Traffic View displays device summary information: Contact Status Contact Status is a color code that shows the status of the connection between SPMA and the device: • Green means a valid connection. • Blue means that SPMA is trying to reach the device but doesn’t yet know if the connection will be successful. • Red means that SPMA has lost contact with the device.
Using the TSX-1620 Bridge View Clicking on the Device button displays the Device menu. The Device menu lets you perform the following: • Open the Bridge Status window. • Display a summary of bridge statistics. • Open the Source Routing Configuration window. • Open the Filtering Database window. • Open the Find MAC Address window. • Open the Spanning Tree Protocol window. • Open the Polling Intervals window.
Using the TSX-1620 Bridge View NOTE The number of bridge interfaces appearing in the Bridge Traffic View depends on the number of different local segment numbers assigned to the TSX-1620’s physical ports. For example, if all of the TSX-1620’s physical ports have the same local segment identifier, the Bridge Traffic View will display a single bridge interface (port).
Using the TSX-1620 Bridge View The Frames/Admin, Source Routing/Transparent, and Delta/Percentage buttons each let you choose one of the two display modes for the Bridge Port boxes. The display mode visible on a button is the one not currently selected. Clicking on a button when the button displays the desired mode type chooses that mode type for the Bridge Port boxes.
Using the TSX-1620 Bridge View Blocking This port is not forwarding or receiving traffic (and therefore no physical address information is added to the Filtering Database) nor is it sending or receiving BPDUs. A port will enter the blocking state for two reasons: if it receives information that another bridge is the designated bridge to the network segment to which this port is attached, or immediately after it has been enabled by management.
Using the TSX-1620 Bridge View Using the Detail View Window The Detail View provides port-level information on two bridge ports. NOTE For the TSX-1620, the Detail View can only be used if you have only two bridge ports configured (i.e., if you have more than two different local segment numbers assigned among all of your physical ports). If three or more bridge ports have been configured, you will be unable to select any bridge ports to view in the Detail View. To open the Detail View: 1.
Using the TSX-1620 Bridge View Each port shows the total frames transmitted and received by the port. Port summary information includes Port Index (at the top of the Bridge Port box), Port Status, Bridge Port State, and Frames Forwarded.
Using the TSX-1620 Bridge View 3. In the Status window, highlight a text box, type in the new information; press Enter or Return on the keyboard to set your changes before selecting a new field. Figure 3-5. Bridge Status Window NOTE Although Date and Time fields are present in the TSX-1620’s Bridge Status window, these values are not supported for the TSX-1620. Any attempt to set a device date or time using this window will result in an error message.
Using the TSX-1620 Bridge View Figure 3-6. Bridge Statistics Window The Bridge Statistics window displays the following information: Bridging Type Type refers to the type of bridging supported by the bridge. • • • • unknown transparent-only sourceroute-only srt (Source Route Transparent) Total Ports Shows the total number of bridge ports supported by this device. Port Displays each port’s index number. IfIndex Interface index; a unique value for each network (interface) to which this port connects.
Using the TSX-1620 Bridge View MtuExceedDiscard Mtu stands for “maximum transfer unit”; it is the largest frame size that can be processed by the TSX-1620. A port discards any received frames that are larger than the Mtu; this field lists how many such frames were discarded. The information in the Bridge Statistics window is a snapshot of the data. When you open the Bridge Statistics window, the application polls the devices for information.
Using the TSX-1620 Bridge View NOTES Cabletron has extended the functionality of the Ethernet port on translational bridges, so the port can be set to Source Route mode. When an Ethernet port is in Source Route mode, on receipt of an SR packet from the Token Ring port, it will save the Source Routing information and send out the packet transparently. When the response comes back, the source routing information will be restored and sent to the Token Ring port.
Using the TSX-1620 Bridge View Two fields at the top of the Filtering Database window provide information about the Filtering Database: Ageing Time (secs) The current setting of the bridge’s Dynamic Ageing Timer, used to purge Forwarding entries from the Filtering Database, or to purge static entries subject to the ageing timer. Learned Entry Discards The number of database entries that never made it into the Filtering Database due to a lack of buffer space. Ideally, this number should be 0.
Using the TSX-1620 Bridge View Receive Port Displays the port on which a packet with the specified source address must be received in order for the filtering actions specified in the Destination Port field to take place. A setting of 0 will apply the filtering action anytime a packet with the specified source address is received by any of the bridge ports.
Using the TSX-1620 Bridge View Since the Forwarding table cannot be edited, you must add an entry to the Static Table in order to change or delete it, as desired. Use the Add to Static Table to add a forwarding entry to the static database. The Ageing Time determines how long a Forwarding entry (or a Static entry with deleteOnTimeout status) is retained before being discarded due to inactivity. Use the Change Ageing Time button to set a new Ageing Time; see the following section for details.
Using the TSX-1620 Bridge View 2. Highlight and edit the Ageing Time (in seconds), and then click mouse button 1 on the Apply button. or 3. Use mouse button 1 to drag the slide bar, then click Apply. or As you change the ageing time, SPMA converts seconds to days:hours:minutes:seconds. 4. Click mouse button 1 next to the slide to increment the time in 100 second jumps, then click Apply. Figure 3-8.
Using the TSX-1620 Bridge View Figure 3-9. Static Table Window Static Address The Static Address field will display the MAC address of the entry you highlighted in the Filtering Database window. If no entry was selected, the address field will contain zeros, and a valid MAC address may be entered. Receive Port The Receive Port list box specifies the port on which packets from the specified static address must be received in order for the static database entry to apply.
Using the TSX-1620 Bridge View deleteOnReset—The entry will deleted when the bridge is reset. deleteOnTimeout—The entry is subject to the ageing timer. 4. After you set the entry’s status, click mouse button 1 on the Apply button. Deleting a Static Table Entry To delete a Static Table entry: 1. In the Filtering Database window, click mouse button 1 in the appropriate selection box to display the Static database. 2. Select the entry you want to delete by clicking it with mouse button 1. 3.
Using the TSX-1620 Bridge View In a network designed with multiple bridges placed in parallel (i.e., attached to the same network segment), Spanning Tree selects a controlling Root Bridge and Port for the entire bridged local area network, and a Designated Bridge and Port for each individual network segment. The Root bridge is the one that selects one of two or more available bridge paths between two end stations, basing its decision on factors associated with each of the bridges in the path.
Using the TSX-1620 Bridge View The Spanning Tree Protocol window displays the following information: Spanning Tree Version The version shows the Spanning Tree Protocol type employed by this bridge: • • • IEEE 802.1d DEC LAN 100 None You must use either 802.1d or DEC to interconnect all bridges in a network using parallel bridges. By default, a Cabletron bridge turns on the 802.1d Spanning Tree. All of Cabletron’s bridge products have the ability to use either the 802.
Using the TSX-1620 Bridge View Max Age The current setting for the bridge’s BPDU ageing timer, in seconds. The ageing timer defines the maximum number of seconds that a Configuration BPDU is retained by the bridge before it is discarded. During normal operation, each bridge in the network receives a new Configuration BPDU before the ageing timer expires. If the timer expires before a new Configuration BPDU is received, it indicates that the former Root is no longer active.
Using the TSX-1620 Bridge View NOTE The values for the Forward Delay, Max Age, Hold Time, and Hello Time fields are stored within the MIB in units of hundredths of a second rather than seconds; your Cabletron management application converts hundredths of a second to seconds for display purposes. You can use any SNMP Set Request tool to edit the values for these three fields; just remember that you must enter your values in hundredths of seconds, rather than in seconds.
Using the TSX-1620 Bridge View Changing Spanning Tree Parameters To change the Bridge Priority, Root Forward Delay, Root Max Age, or Root Hello Time: 1. In the Spanning Tree Protocol window, highlight the current value of the field you want to change. 2. Type the new value in the appropriate text box and press Enter or Return on the keyboard.
Using the TSX-1620 Bridge View component— is used to determine which port on this bridge will be the Designated Port for that segment. A lower number indicates a higher priority; the default is 80. The allowable range is 0 to FF. Path Cost The portion of the total path cost associated with this port. Lowering a port’s Path Cost makes a port more competitive in the selection of the Designated Port. The default value is 100 for Cabletron bridges. The allowable range is from 1 to 65535. Figure 3-12.
Using the TSX-1620 Bridge View Designated Bridge Displays the MAC address and priority component of the Bridge ID for the bridge that is believed to be the Designated Bridge for the network segment associated with this port. The Designated Bridge ID, along with the Designated Port and Port Identifier parameters for the port, is used to determine whether this port should be the Designated Port for the network segment to which it is attached.
Using the TSX-1620 Bridge View The scroll list at the top of the window lists each physical TSX-120 port and its Spanning Tree Explorer (STE) Span Mode, which determines how this port will behave when presented with an STE packet. Possible values are as follows: auto-span This value can only be returned by a bridge that implements the Spanning Tree Protocol. A port set to auto-span will forward an STE packet when it is in the Forwarding state; otherwise, it will discard the packet.
Using the TSX-1620 Bridge View descriptors (bridge hops) allowed in a packet’s Routing Information Field. A bridge port will discard any explorer packets whose RIF’s exceed the maximum number of routing descriptors. Local Segment Number Normally, when assigning local segment numbers, you must assign a unique number to each network segment in a network; this field represents the network segment to which this port is attached physically.
Using the TSX-1620 Bridge View NOTES A Source Route-capable bridge has the ability to embed Largest Frame size information into the explorer packets. If there are multiple bridge hops from one end node to another, this allows the end stations to realize the maximum frame size limits for any network segment in the path between them, and adjust their Mtu size accordingly.
Using the TSX-1620 Bridge View Creating Bridge Traffic Charts, Graphs and Meters The Bridge application uses the SPMA Charts, Graphs and Meters tools to depict bridge statistics describing activity at the bridge-port level. Once running, however, a pie chart, graph or meter is independent from the application where it was started. Although the windows you open to create pie charts, graphs and meters have unique variable lists, the procedures for creating a pie chart, a graph or a meter are the same.
Using the TSX-1620 Bridge View For complete descriptions of chart, graph and meter variables and details on how to create and control a pie chart, graph or meter, see the chapter on charts, graphs and meters in the SPMA Tools Guide.
Using the TSX-1620 Bridge View A traffic level is the specified value of forwarded frames as a percentage of total received frames. You can specify traffic levels that define the boundary between the low and medium ranges and between the medium and high ranges. When SPMA polls the device and detects that the percentage of forwarded frames has moved into a new range, heading either up or down, the notification options and conditions in use for that port take place. Figure 3-15.
Using the TSX-1620 Bridge View 2. In the Modify Range section of the Forwarding Thresholds window, you can edit the line that displays the high end of the Low and Mid ranges, or you can use the slide bars to specify the thresholds. You can also assign a color to each of the three ranges. The Bridge Port boxes on the Bridge Traffic View will be colored according to the settings made here (i.e.
Using the TSX-1620 Bridge View b. If you select the Remain—In box, notification takes place when the threshold passes from one range to another, and stays in that range for the number of polling cycles specified in the Delay box. c.
