Overview
This chapter describes the features and components of the Cisco 1538 series Micro Hubs
10/100 (hereafter collectively referred to as the “Micro Hubs”). These class-II repeaters are
a part of the Cisco Networked Office stack, a family of stackable, desktop networking
platforms designed for small workgroups.
Overview of the Micro Hubs
The Micro Hubs are stackable, 8-port, 10/100-Mbps, autosensing Fast Ethernet class II
repeaters with internal bridging.
•The Cisco 1538M Micro Hub 10/100 (hereafter referred to as the “managed hub”) can
be monitored through a web console or the command-line interface. This hub can
manage a stack of up to 3 additional Micro Hubs and serve up to 32 user connections.
For an overview of the management features of this hub, see the “Management Options
(Cisco 1538M Hub)” section on page 1-7.
•The Cisco 1538 Micro Hub 10/100 (hereafter referred to as the “manageable hub”) is
without internal management applications but can be monitored and controlled through
interconnection to a managed hub.
Either hub model can be a standalone networking device or can connect to other routers,
switches, and hubs to form a larger network. You can also stack and connect up to four hubs
through the rear-panel ports to form a larger network.

Feature Description
Management • Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON)
provides configuration, management and monitoring on a per-port and per-hub basis.
• Three management interface options:
— The Cisco ConfigMaker configuration application provides a single configuration
interface for all products in the Cisco Networked Office stack.
— Cisco 1538 Hub Manager with an embedded HTTP server provides an interface for
all supported management functions.
— A command-line interface (CLI) supports management through Telnet in-band or
console port out-of-band connections.
• Menu-based diagnostic console for hub recovery tasks.
• Cisco Discovery Protocol (CDP) enables network management stations to discover the
hub in a network topology.
• Manages up to 32 ports in a 4-hub stack with one IP address.
Stacking • Integrated stacking ports allow up to four hubs in a single collision domain.
• Two managed hubs can be deployed for management backup.
Performance • Autosensing on all ports allows automatic configuration for either 10BaseT or
100BaseT connections.
• Built-in high-speed bridge function automatically connects 10BaseT and 100BaseT
workstations without an external switch or router.
• Embedded switch supports store-and-forward switching and filtering and forwarding
rate at full-wire speed.
MDI/MDI-X connectivity • MDI/MDI-X option for port 5 inter-hub connectivity without crossover cables.
• Class II repeater supports a two-hub daisy chain.
Connectivity • Complies to the IEEE 802.3 10BaseT and 802.3u 100BaseTX specifications.
Security slot • The switch can be secured to a desktop or other surface using lockdown equipment.

Stack Management
Micro Hubs can be interconnected by using the stacking cable and the stacking connectors
on the rear panel of the hubs, creating a stack of up to four Micro Hubs (Figure 1-4). The
interconnected units in that stack appear to the rest of the network and to the management
interface as a single logical repeater. You can have a second managed hub in the stack act
as a redundant stack manager in case the primary manager fails.
Note You need at least one managed hub in your stack if you want to manage the stack.

Management Options (Cisco 1538M Hub)
Management Options (Cisco 1538M Hub)
The Cisco 1538M hub can manage a single hub or a hub stack. You can use the default
settings shipped with the hub, or you can customize the configuration through the Cisco
1538 Hub Manager web-based interface, the CLI, or SNMP.
The Cisco 1538 Hub Manager is the easiest interface to use for the basic configuration and
monitoring tasks. To perform all the configuration and monitoring tasks, use the CLI and
SNMP.
This section provides the following information:
•List of default configuration settings for the hub
•Overview of the Cisco 1538 Hub Manager and the basic management tasks you can
perform using it
Note Procedures for performing management tasks and detailed information about the
Cisco 1538 Hub Manager pages are also provided in the Cisco 1538 Hub Manager
online help.
•Overview of the CLI, which is fully described in the Cisco 1538 Series Micro Hub
10/100 Command Reference.
•Overview of SNMP and the hub Management Information Base (MIB) files.
Note The menu-based diagnostic console is described in the “Recovery Procedures Using
the Diagnostic Console” section on page 4-7.

Default Configuration Settings
The hub is designed to operate with little or no user intervention. After you assign the IP
information, the hub uses its default settings (Table 1-2) and begins forwarding packets as
soon as it is powered up and connected to compatible devices.
.
For procedures on how to reset all hub console port settings to the factory defaults, see the
“Resetting the Hub to the Factory Defaults” section on page 4-14.

Overview of the Cisco 1538 Hub Manager
Overview of the Cisco 1538 Hub Manager
The Cisco 1538 Hub Manager (hereafter referred to as the hub manager) is a web-based
graphical user interface for basic hub configuration and monitoring. Using the hub
manager, you can configure and monitor the hub from anywhere on your intranet.
Each hub manager page
•Provides fields, check boxes, and lists for changing the configuration settings
•Displays current information about the hub
•Provides online help for each page
—Detailed information about the fields, lists, check boxes, and buttons
—Specific procedures for performing management tasks
To use the hub manager, you must have one of these web browsers installed on your
management station:
•Netscape Communicator 4.03 or higher
•Microsoft Internet Explorer 4.01 or higher
Management Tasks Supported on the Hub Manager
The management tasks you can perform from the hub manager can be grouped as described
in Table 1-3.
Procedures for accessing and using the hub manager are provided in
•“Accessing the Cisco 1538 Hub Manager” section on page 2-27
•Chapter 3, “Configuring and Monitoring from the Hub Manager”
Note Information provided in Chapter 3, “Configuring and Monitoring from the Hub
Manager,” is also provided in the hub manager online help.

Overview of the Command-Line Interface
Using the CLI, you can access the hub software and perform the same basic system
configuration and system monitoring tasks available through the hub manager. You can also
perform privileged configuration and troubleshooting tasks available only through the CLI
and SNMP.
Procedures describing how to access the CLI are in the “Accessing the CLI” section on
page 2-29. For complete information about using the CLI, refer to the Cisco 1538 Series
Micro Hub 10/100 Command Reference.
