GETTING STARTED I Chapter 1 Administration Overview Chapter 2 Command Summary
1 ADMINISTRATION OVERVIEW This chapter introduces the Administration Console software that is supplied with your system, the types of commands that you use to perform network tasks, the valid syntax for command abbreviations, and some shortcuts to help you navigate through the menus. It also provides an overview of the management software that is specific to the CoreBuilder® 9000 Enterprise Switch.
CHAPTER 1: ADMINISTRATION OVERVIEW You use the Administration Console software to configure your system parameters (or, on the CoreBuilder 9000, to configure your module parameters) and display statistics and counters. For more complete network management, you can use an external application, such as 3Com’s Transcend® Network Control Services tool suite.
Management and Data Channels 31 ATM LMA management of ATM switch fabric modules and ATM interface modules is outside of the scope of this guide. To learn about managing the ATM Enterprise Switch and ATM modules using the ATM LMA, see the CoreBuilder 9000 ATM Enterprise Switch Management Guide. You cannot manage the EME using the ATM LMA, and you cannot manage ATM Switch Fabric Modules or ATM interface modules using the EME Management Console.

EME Overview CoreBuilder 9000 Management Features EME Overview 33 You can manage the CoreBuilder 9000 system through a terminal interface, through the Simple Network Management Protocol (SNMP), ® and through the 3Com Transcend Network Control Services. The EME is the primary communication mechanism into the chassis and modules. You manage other intelligent modules within the chassis through the EME.
CHAPTER 1: ADMINISTRATION OVERVIEW Configuration Tasks To help you configure your system, the top-level menu of the Administration Console groups the commands into types for certain tasks, as listed in Table 4. Not all menus and tasks are available on all systems.

CHAPTER 1: ADMINISTRATION OVERVIEW Accessing Your System You access the Administration Console for your system in one of two ways: ■ For all systems except the CoreBuilder 9000 — Access the Administration Console for the first time at the Administer level and press Return at the password prompt (the initial password is null).
Access Examples Access Examples 37 The examples in this section show how the top-level menu structure of the Administration Console changes. The menus that you see in the Administration Console vary depending on: ■ Which 3Com system you are viewing (as described in “Accessing Your System” earlier in this chapter). ■ Your level of access. ■ The optional interface modules, switch fabric modules, and other hardware options that you configure into your system.
CHAPTER 1: ADMINISTRATION OVERVIEW Write Access Example When you enter the Administration Console with write access, the system menu contains a subset of the complete menu, focusing on the network, as shown in this example on the CoreBuilder 3500: Select menu option: system Menu options (CoreBuilder-2B4200): -----------------------------------------display - Display the system configuration console - Administer console-level functions fileTransfer - Set the file transfer protocol snapshot - Display all
Access Examples Using Menus to Perform Tasks 39 When you access the Administration Console, the top-level menu appears. You perform administrative tasks by selecting options from this menu and its submenus. A brief description accompanies each option in the display. The commands that you can use depend on the system that you have, your level of access, and the types of modules and other hardware options that are configured for your system.
CHAPTER 1: ADMINISTRATION OVERVIEW Selecting Menu Options To select a menu option, at the prompt enter the menu option or enough of the name to uniquely identify it within the particular menu. Example: to access the module menu from the top level of the Administration Console on a module in the CoreBuilder 9000, enter: Select a menu option: module Menu options are not case sensitive.
Entering Values 41 Entering Abbreviated Commands You can abbreviate command strings by typing only as much of the command as is necessary to make it unique: Select a menu option: b po stpc When you correctly enter either a full or an abbreviated command string, you move to the last menu level or option that is specified in the string. Information that is relevant to that option appears as a menu, a prompt, or a display.
CHAPTER 1: ADMINISTRATION OVERVIEW Navigating Through the Menus The Administration Console provides several shortcuts: ■ Press Esc (the Escape key) — To move quickly to the top-level menu without backtracking through each intermediate menu. The top-level menu immediately appears. ■ Enter q — ■ ■ To move up through the hierarchy, that is, to move to the menu that is one level higher in the hierarchy To cancel an operation that is currently in progress. The previous menu appears.

10 BRIDGE PORT PARAMETERS This chapter provides guidelines and other key information about how to manage bridge ports in your system. This chapter covers bridge port options only. For information about other bridge menu options, use the Table of Contents to find the appropriate chapter in this Command Reference Guide. For more information about configuring bridge ports in your network, see the Implementation Guide for your system.
CHAPTER 10: BRIDGE PORT PARAMETERS bridge port summary ✓ 3500 ✓ 9000 ✓ 9400 ✓ 3900 ✓ 9300 Displays a summary of bridge port information, including the Spanning Tree Protocol (STP) configurations for selected bridge ports. Valid Minimum Abbreviation b po su Important Considerations ■ The port numbering that is displayed is always sequential, although it depends on the placement of the modules that you have configured into your system.
bridge port summary Field Description portNumber Logical index number that the system assigns to the bridge port, which may not correspond with the physical port number depending on your system configuration. (For example, when you define a trunk, only the anchor port receives a portNumber.) As you add and remove logical ports, portNumbers are reassigned so that they remain consecutive. rxDiscards Total number of frames received on the bridge port that have been discarded.
CHAPTER 10: BRIDGE PORT PARAMETERS Field Description stp Configurable status of STP on a port. If bridge-wide STP is enabled, the port STP configuration options are: ■ ■ ■ enabled — STP sets the operating state of the port (blocking, listening, etc.) according to network topology characteristics. This is the default configuration for all ports. disabled — STP is disabled and the port is disabled. The port does not participate in STP decisions, frame reception, or frame transmission.
bridge port detail bridge port detail ✓ 3500 ✓ 9000 ✓ 9400 ✓ 3900 ✓ 9300 283 Displays detailed information about bridge ports, including the Spanning Tree Protocol (STP) configurations for the bridge port. Valid Minimum Abbreviation b po d Important Considerations ■ The port numbering that is displayed for your ports is always sequential, although it depends on the placement of the modules that you have configured into your system.
CHAPTER 10: BRIDGE PORT PARAMETERS Field Description linkState State of the link (up or down), that is, whether it is available for communication. pathCost Cost to add to the total path cost when this port is the root port. To configure a port’s STP cost, see “bridge port stpCost” in this chapter. portNumber Logical index number that the system assigns to the bridge port, which may not correspond with the physical port number depending on your system configuration.
bridge port detail 285 Field Description rxFrames Total number of frames that this bridge port received from its segment. However, unlike the rxFrames field in the Ethernet display which counts all frames, this field does not count frames in error. Thus, this value may be lower than the value shown in the rxFrames field in the Ethernet display. rxInternalFilters (3500 and 9000 L3) Number of frames discarded due to customer filters on the rxInternal path.
CHAPTER 10: BRIDGE PORT PARAMETERS Field Description SRHopLimit (3500 and 9000 L3) (Not available at this release) state Current operating state of the port: ■ ■ ■ ■ ■ stp Blocking — The bridge continues to run STP on the port, but the bridge does not receive packets from the port, learn locations of station addresses from it, or forward packets onto it.
bridge port detail 287 Field Description txFrames Number of frames that this port transmitted to its segment. This object counts a frame transmitted on the interface that corresponds to this port only if the frame is for a protocol that the local bridging function is processing (includes bridge management frames). txMcastFilters (3500 and 9000 L3) Number of frames that this port discarded because of a user-defined packet filter on its “transmit multicast” path.
CHAPTER 10: BRIDGE PORT PARAMETERS bridge port multicastLimit ✓ 3500 ✓ 9000 ✓ 9400 ✓ 3900 ✓ 9300 Sets a threshold value on a bridge port that affects the per-second forwarding rate of multicast or broadcast traffic that originates on the segment connected to that port.

CHAPTER 10: BRIDGE PORT PARAMETERS bridge port stpCost ✓ 3500 ✓ 9000 ✓ 9400 ✓ 3900 ✓ 9300 Sets the path cost that the Spanning Tree Protocol (STP) adds to the root cost field in a configuration message that the port receives. The system uses this value to determine the path cost to the root through the port. The current value is shown in the pathCost field of the bridge port detail display.
bridge port stpPriority bridge port stpPriority ✓ 3500 ✓ 9000 ✓ 9400 ✓ 3900 ✓ 9300 291 Sets the Spanning Tree Protocol (STP) bridge port priority. This value influences the choice of port when the bridge has two or more ports that have the same path cost and that are connected to the same LAN, which creates a loop. STP selects the bridge port with the lowest priority and places the remaining ports in the blocking state. The current value is shown in the priority field of the bridge port detail display.

bridge port address flushAll bridge port address flushAll ✓ 3500 ✓ 9000 ✓ 9400 297 Removes all static and dynamic MAC addresses from the bridge ports that you select. Static MAC addresses are those that you specified using the bridge port address add option. Dynamic MAC addresses are those that the bridge learned automatically. Valid Minimum Abbreviation b po a flusha ✓ 3900 ✓ 9300 Important Consideration ■ If the bridge is power cycled, reset, or rebooted, the address table is automatically flushed.
CHAPTER 10: BRIDGE PORT PARAMETERS bridge port address flushDynamic ✓ 3500 ✓ 9000 ✓ 9400 ✓ 3900 ✓ 9300 Removes all dynamic MAC addresses from the bridge ports that you select. Dynamic MAC addresses are those that the bridge learned by receiving and processing packets. Valid Minimum Abbreviation b po a flushd Important Consideration ■ If the bridge is power cycled, reset, or rebooted, the address table is automatically flushed.
11 TRUNKS You can configure a system to aggregate multiple network links into a single trunk. With trunking you can create high-speed point-to-point or multipoint connections without changing or replacing existing cabling. In addition, trunking provides automatic point-to-point redundancy between two devices. Redundant links normally have one link disabled by Spanning Tree (to prevent looping); trunking utilizes both links.
CHAPTER 11: TRUNKS Menu Structure The commands that you can use depend on the system that you have, your level of access, and the types of modules and other hardware options that are configured for your system. The following diagram shows the complete list of commands for all systems. See the checklist at the beginning of each command description in this chapter for whether your system supports the command.
