Overview


This chapter describes the features and components of the Cisco 1548M Micro Switch 10/100 (hereafter referred to as the "Micro Switch"). The Micro Switch is part of the Cisco Networked Office stack, a family of small-office networking platforms.

Overview of the Micro Switch

The Micro Switch is an 8-port managed switch with dual-speed, autonegotiated 10/100 Ethernet ports. The switch supports Spanning-Tree Protocol (STP), port-based virtual LANs (VLANs), Simple Network Management Protocol (SNMP) and web management functions.

Features

describes the features of the Micro Switch.

Table 1-1 Feature Summary of the Micro Switch 

Feature
Description
Management

SNMP and Remote Monitoring (RMON) support provides full configuration, management, and monitoring on a per-port basis.

Three management interface options:

The Cisco ConfigMaker configuration management application provides a single configuration interface for all products in the Cisco Networked Office stack.

A web console with an embedded HTTP server provides an interface for all supported management functions.

A command-line interface (CLI) provides the option of management through Telnet in-band or console port out-of-band connections.

Menu-based diagnostic console for switch recovery tasks.

CiscoView software, a GUI-based device management application, provides dynamic status, statistics, and comprehensive configuration information.

Cisco Discovery Protocol (CDP) enables network management stations to discover the switch in a network topology.

VLANs

The switch supports up to four port-based VLANs. Each port can be assigned to one or to all VLANs.

Performance

Autosensing on all ports allows automatic configuration for either 10BaseT or 100BaseT connections.

Each port automatically negotiates with a connected network device to operate in either half- or full-duplex mode.

The switch stores each incoming packet in memory and then forwards the packet to the appropriate port for delivery.

Security slot

The switch can be secured to a desktop or other surface using lockdown equipment.

Supported addresses

The switch supports 4096 source and destination addresses.

Standards conformance

The switch complies with IEEE 802.3 10BaseT and IEEE 802.3u 100BaseTX standards.


Front-Panel LEDs

Management Options

You can use the default settings shipped with the switch, or you can customize the configuration through the Cisco 1548 Switch Manager web-based interface, the CLI, or SNMP.

The Cisco 1548 Switch 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.

Note   The menu-based diagnostic console is described in the "Recovery Procedures Using the Diagnostic Console" section.


Default Configuration Settings

The switch is designed to operate with little or no user intervention. After you assign the IP information, the switch uses its default settings () and begins forwarding packets as soon as it is powered up and connected to compatible devices.

Overview of the Cisco 1548 Switch Manager

The Cisco 1548 Switch Manager (hereafter referred to as the switch manager) is a web-based graphical user interface for basic switch configuration and monitoring. Using the switch manager, you can configure and monitor the switch from anywhere on your intranet.

Each switch manager page

Provides fields, check boxes, and lists for changing the configuration settings

Displays current information about the switch

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 switch 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 Switch Manager

The management tasks you can perform from the switch manager can be grouped as described in .

Procedures for accessing and using the switch 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 "," is also provided in the switch manager online help.



Overview of the Command-Line Interface

Using the CLI, you can access the switch software and perform the same basic system configuration and system monitoring tasks available through the switch 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 1548M Micro Switch 10/100 Command Reference.

Overview of SNMP

You can configure and monitor the switch by accessing the Management Information Base (MIB) variables through Simple Network Management Protocol (SNMP), an application-layer protocol facilitating the exchange of management information between network devices. The switch supports a comprehensive set of MIB objects, including four Remote Monitoring (RMON) groups. (The "Accessing the MIB Files through SNMP" section provides information about the MIB files and about accessing them.)

The SNMP system consists of three parts: SNMP manager, SNMP agent, and the MIB files. SNMP places all operations in a get-request, get-next-request, and set-request format. For example, an SNMP manager can get a value from an SNMP agent or store a value into that SNMP agent. The SNMP manager can be part of a network management system (NMS), and the SNMP agent can reside on a networking device such as a switch. You can compile the switch MIB files with your network management software. The SNMP agent can respond to MIB-related queries being sent by the NMS.

An example of an NMS is the CiscoWorks network management software. CiscoWorks uses the switch MIB variables to set device variables and to poll devices on the network for specific information. The results of a poll can be displayed as a graph and analyzed in order to troubleshoot internetworking problems, increase network performance, verify the configuration of devices, monitor traffic loads, and more.

Figure 1-3 shows how the SNMP agent gathers data from the MIB file, which holds information about device parameters and network data. The agent can send traps, or notification of certain events, to the manager.

Figure 1-3 SNMP Network


Note   Make sure you use the correct Read and Write community strings so that your SNMP request does not fail. Refer to the online help SNMP Management Page for the correct community strings.


The SNMP manager uses information in the MIB files to perform the operations described in .

Table 1-4 SNMP Manager Operations

Operation
Description

get-request

Retrieves a value from a specific variable.

get-next-request

Retrieves a value from a variable within a table.1

get-response

Reply to a get-request, get-next-request, and set-request sent by an NMS.

set-request

Store a value in a specific variable.

trap

Send an unsolicited message from an SNMP agent to an SNMP manager indicating that some event has occurred.

1 An SNMP manager does not need the exact variable name. It sequentially searches to find the needed variable from within a table.


Network Examples Using the Micro Switch
