The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering new products within 30 days of purchase from SMC or its Authorized Reseller. Registration can be accomplished via the enclosed product registration card or online via the SMC web site. Failure to register will not affect the standard limited warranty. The Limited Lifetime warranty covers a product during the Life of that Product, which is defined as the period of time during which the product is an “Active” SMC product. A product is considered to be “Active” while it is listed on the current SMC price list. As new technologies emerge, older technologies become obsolete and SMC will, at its discretion, replace an older product in its product line with one that incorporates these newer technologies. At that point, the obsolete product is discontinued and is no longer an “Active” SMC product.

Description of Software Features

The switch provides a wide range of advanced performance enhancing features. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. Broadcast storm suppression prevents broadcast traffic storms from engulfing the network. Port-based and protocol-based VLANs, plus support for automatic GVRP VLAN registration provide traffic security and efficient use of network bandwidth. CoS priority queueing ensures the minimum delay for moving real-time multimedia data across the network. While multicast filtering provides support for real-time

network applications. Some of the management features are briefly described below.

Configuration Backup and Restore – You can save the current configuration settings to a file on a TFTP server, and later download this file to restore the switch configuration settings.

Authentication – This switch authenticates management access via the console port, Telnet or Web browser. User names and passwords can be configured locally or can be verified via a remote authentication server (i.e., RADIUS or TACACS+). Port-based authentication is also supported via the IEEE 802.1X protocol. This protocol uses the Extensible Authentication Protocol over LANs (EAPOL) to request user credentials from the 802.1X client, and then verifies the client’s right to access the network via an authentication server (i.e., RADIUS server).

Other authentication options include HTTPS for secure management access via the web, SSH for secure management access over a Telnet-equivalent connection, SNMP v3, IP address filtering for SNMP/ Web/Telnet management access, and MAC address filtering for port access.

Access Control Lists – ACLs provide packet filtering for IP frames (based on address, protocol, TCP/UDP port number or TCP control code) or any frames (based on MAC address or Ethernet type). ACLs can by used to improve performance by blocking unnecessary network traffic or to implement security controls by restricting access to specific network resources or protocols.

Port Configuration – You can manually configure the speed, duplex mode, and flow control used on specific ports, or use auto-negotiation to detect the connection settings used by the attached device. Use the full-duplex mode on ports whenever possible to double the throughput of switch connections. Flow control should also be enabled to control network traffic during periods of congestion and prevent the loss of

1-3

NTRODUCTION

packets when port buffer thresholds are exceeded. The switch supports flow control based on the IEEE 802.3x standard.

Rate Limiting – This feature controls the maximum rate for traffic transmitted or received on an interface. Rate limiting is configured on interfaces at the edge of a network to limit traffic into or out of the network. Traffic that falls within the rate limit is transmitted, while packets that exceed the acceptable amount of traffic are dropped.

Port Mirroring – The switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a protocol analyzer or RMON probe to this port to perform traffic analysis and verify connection integrity.

Port Trunking – Ports can be combined into an aggregate connection. Trunks can be manually set up or dynamically configured using IEEE

802.3ad Link Aggregation Control Protocol (LACP). The additional ports dramatically increase the throughput across any connection, and provide redundancy by taking over the load if a port in the trunk should fail. The switch supports up to 32 trunks.

Broadcast Storm Control – Broadcast suppression prevents broadcast traffic from overwhelming the network. When enabled on a port, the level of broadcast traffic passing through the port is restricted. If broadcast traffic rises above a pre-defined threshold, it will be throttled until the level falls back beneath the threshold.

Static Addresses – A static address can be assigned to a specific interface on this switch. Static addresses are bound to the assigned interface and will not be moved. When a static address is seen on another interface, the address will be ignored and will not be written to the address table. Static addresses can be used to provide network security by restricting access for a known host to a specific port.

ESCRIPTION OF SOFTWARE FEATURES

IEEE 802.1D Bridge – The switch supports IEEE 802.1D transparent bridging. The address table facilitates data switching by learning addresses, and then filtering or forwarding traffic based on this information. The address table supports up to 16K addresses.

Store-and-Forward Switching – The switch copies each frame into its memory before forwarding them to another port. This ensures that all frames are a standard Ethernet size and have been verified for accuracy with the cyclic redundancy check (CRC). This prevents bad frames from entering the network and wasting bandwidth.

To avoid dropping frames on congested ports, the switch provides 1 MB for frame buffering. This buffer can queue packets awaiting transmission on congested networks.

Spanning Tree Algorithm – The switch supports these spanning tree protocols:

Spanning Tree Algorithm (STA, IEEE 802.1D) – When there are multiple physical paths between segments, this protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should fail for any reason, an alternate path will be activated to maintain the connection.

Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol reduces the convergence time for network topology changes to about 3-5 seconds of that required by the older IEEE 802.1D STA standard. It is intended as a complete replacement for STA, but can still interoperate with switches running the older standard by automatically reconfiguring ports to STP-compliant mode if they detect STA protocol messages from attached devices.

Multiple Spanning Tree Protocol (MSTP, IEEE 802.1s) – This protocol is a direct extension of RSTP. It can provide an independent spanning tree for different VLANs. It simplifies network management, provides for even faster convergence than RSTP by limiting the size of each region, and

1-5

NTRODUCTION

prevents VLAN members from being segmented from the rest of the group (as sometimes occurs with IEEE 802.1D STA).

Virtual LANs – The switch supports up to 255 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. The switch supports tagged VLANs based on the IEEE 802.1Q standard. Members of VLAN groups can be dynamically learned via GVRP, or ports can be manually assigned to a specific set of VLANs. This allows the switch to restrict traffic to the VLAN groups to which a user has been assigned. By segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade performance in a flat network.

• Simplify network management for node changes/moves by remotely configuring VLAN membership for any port, rather than having to manually change the network connection.

• Provide data security by restricting all traffic to the originating VLAN, except where a connection is explicitly defined via the switch’s routing service.

• Use private VLANs to restrict traffic to pass only between data ports and the uplink ports, thereby isolating adjacent ports within the same VLAN, and allowing you to limit the total number of VLANs that need to be configured.

• Use protocol-based VLANs such as IP and IPX to restrict traffic to specified interfaces based on protocol type.

Traffic Prioritization – This switch prioritizes each packet based on the required level of service, using eight priority queues with strict or Weighted Round Robin Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can data and best-effort data.

be used to provide independent priorities for delay-sensitive

This switch also supports several common methods of prioritizing layer 3/4 traffic to meet application requirements. Traffic can be prioritized based on the priority bits in the IP frame’s Type of Service (ToS) octet or the number of the TCP/UDP port. When these services are enabled, the

1-6

YSTEM DEFAULTS

priorities are mapped to a Class of Service value by the switch, and the traffic then sent to the corresponding output queue.

Multicast Filtering – Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and Query to manage multicast group registration.

System Defaults

The switch’s system defaults are provided in the configuration file “Factory_Default_Config.cfg.” To reset the switch defaults, this file should be set as the startup configuration file (page 3-25).

Connecting to the Switch

Configuration Options

The switch includes a built-in network management agent. The agent offers a variety of management options, including SNMP, RMON (Groups 1,2 3, 9) and a Web-based interface. A PC may also be connected directly to the switch for configuration and monitoring via a command line interface (CLI).

Note: The IP address for this switch is obtained via DHCP by default.

To change this address, see “Setting an IP Address” on page 2-10.

The switch’s HTTP Web agent allows you to configure switch parameters, monitor port connections, and display statistics using a standard Web browser such as Netscape Navigator version 6.2 and higher or Microsoft IE version 5.0 and higher. The switch’s Web management interface can be accessed from any computer attached to the network.

The CLI program can be accessed by a direct connection to the RS-232 serial console port on the switch, or remotely by a Telnet connection over the network.

The switch’s management agent also supports SNMP (Simple Network Management Protocol). This SNMP agent permits the switch to be managed from any system in the network using network management software such as SMC EliteView.

2-1

NITIAL CONFIGURATION

The switch’s Web interface, CLI configuration program, and SNMP agent allow you to perform the following management functions:

• Set user names and passwords

• Set an IP interface for the switch

• Configure SNMP parameters

• Enable/disable any port

• Set the speed/duplex mode for any port

• Configure the bandwidth of any port by limiting input or output rates

• Control port access through IEEE 802.1X security or static address filtering

• Filter packets using Access Control Lists (ACLs)

• Configure up to 255 IEEE 802.1Q VLANs

• Enable GVRP automatic VLAN registration

• Configure IGMP multicast filtering

• Upload and download system firmware via TFTP

• Upload and download switch configuration files via TFTP

• Enable port mirroring

• Set broadcast storm control on any port

• Display system information and statistics

• Configure any stack unit through the same IP address

Required Connections

The switch provides an RS-232 serial port that enables a connection to a PC or terminal for monitoring and configuring the switch. A null-modem console cable is provided with the switch.

2-2

ONNECTING TO THE SWITCH

Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the switch. You can use the console cable provided with this package, or use a null-modem cable that complies with the wiring assignments shown in the Installation Guide.

To connect a terminal to the console port, complete the following steps:

1. Connect the console cable to the serial port on a terminal, or a PC running terminal emulation software, and tighten the captive retaining screws on the DB-9 connector.

2. Connect the other end of the cable to the RS-232 serial port on the switch.

3. Make sure the terminal emulation software is set as follows:

• Select the appropriate serial port (COM port 1 or COM port 2).

• Set to any of these baud rates: 9600, 19200, 38400, 57600, 115200 (Note: Set to 9600 baud to view all system initialization messages.)

• Set the data format to 8 data bits, 1 stop bit, and no parity.

• Set flow control to none.

• Set the emulation mode to VT100.

• With HyperTerminal, select Terminal keys, not Windows keys.

Notes: 1. When using HyperTerminal with Microsoft

make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.

2. Refer to “Line Commands” on page 4-13 for a complete description of console configuration options.

3. Once you have set up the terminal correctly, the console login screen will be displayed.

NITIAL CONFIGURATION

For a description of how to use the CLI, see “Using the Command Line Interface” on page 4-1. For a list of all the CLI commands and detailed information on using the CLI, refer to “Command Groups” on page 4-11.

Remote Connections

Prior to accessing the switch’s onboard agent via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using a console connection, DHCP or BOOTP protocol.

The IP address for this switch is assigned via DHCP by default. To manually configure this address or enable dynamic address assignment via DHCP or BOOTP, see “Setting an IP Address” on page 2-10.

Notes: 1. This switch supports four concurrent Telnet sessions.

2. Each VLAN group can be assigned its own IP interface

address (page 2-10). You can manage the stack via any IP interface in the stack. In other words, the Master unit does not have to include an active port member of a VLAN interface used for management access.

After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network. The onboard configuration program can be accessed using Telnet from any computer attached to the network. The switch can also be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above), or from a network computer using SNMP network management software.

Note: The onboard program only provides access to basic configuration

functions. To access the full range of SNMP management functions, you must use SNMP-based network management software.

2-4

TACK OPERATIONS

Stack Operations

Up to eight 24-port or 48-port Gigabit switches can be stacked together as described in the Installation Guide. One unit in the stack acts as the Master for configuration tasks and firmware upgrade. All of the other units function in Slave mode, but can automatically take over management of the stack if the Master unit fails.

To configure any unit in the stack, first verify the unit number from the front panel of the switch, and then select the appropriate unit number from the web or console management interface.

Selecting the Stack Master

Note the following points about unit numbering:

• When the stack is initially powered on, the Master unit is designated as unit 1 for a ring topology. For a line topology, the stack is simply numbered from top to bottom, with the first unit (i.e., the unit with no connection on the Up port) in the stack designated as unit 1. This unit identification number appears on the Stack Unit ID LED on the front panel of the switch. It can also be selected on the front panel graphic of the web interface, or from the CLI.

• If more than one stack Master is selected using the Master/Slave push button on the switch’s front panel, the system will select the unit with the lowest MAC address as the Master.

• If the Master unit fails and another unit takes over control of the stack, the unit numbering will not change.

• If a unit in the stack fails or is removed from the stack, the unit numbers will not change. This means that when you replace a unit in the stack, the original configuration for the failed unit will be restored to the replacement unit.

• If a unit is removed from the stack and later reattached to the stack, it will retain the original unit number obtained during stacking.

2-5

NITIAL CONFIGURATION

• If a unit is removed from the stack, and powered up as a stand-alone unit, it will also retain the original unit number obtained during stacking.

Master Backup Unit

Once the Master unit finishes booting up, the Slave unit in the stack with the lowest MAC address functions as the primary backup unit. The stack Master immediately downloads all configuration information to the backup unit and continues to update it with information about any subsequent configuration changes made to any unit in the stack. If the Master unit fails or is powered off, the backup unit will take control of the stack without any loss of configuration settings.

The Slave unit with the lowest MAC address always functions as the backup unit. If you want to ensure a logical fail over to the next unit down in the stack, place the Slave unit with the lowest MAC address directly beneath the Master unit in the stack.

Recovering from Stack Failure or Topology Change

When a link or unit in the stack fails, a trap message is sent and a failure event is logged. The stack will reboot after any system failure or topology change. It takes two to three minutes for the stack to reboot. If the Master unit fails, the backup unit will take over operations as the new Master unit, reboot the stack, and then select another backup unit after the stack finishes rebooting. Also note that powering down a unit or inserting a new unit in the stack will cause the stack to reboot. If a unit is removed from the stack (due to a power down or failure) or a new unit added to the stack, the original unit IDs are not affected after rebooting, and a new unit is assigned the lowest available unit ID.

Broken Link for Line and Wrap-around Topologies

All units in the stack must be connected via stacking cable. You can connect the units in a simple cascade configuration from the top to the bottom unit. Using this kind of line topology, if any link or unit in the stack

2-6

TACK OPERATIONS

fails, the stack will be broken in two. The Stack Link LED on the unit that is no longer receiving traffic from the next unit up in the stack will begin flashing to indicate that the stack link is broken.

When the stack fails, a Master unit is selected from the two stack segments, either the unit with the Master button depressed, or the unit with the lowest MAC address if the Master button is not depressed on any unit. The stack reboots and resumes operations. However, note that the IP address will be the same for any common VLANs (with active port connections) that appear in both of the new stack segments. To resolve the conflicting IP addresses, you should manually replace the failed link or unit as soon as possible. If you are using a wrap-around stack topology, a single point of failure in the stack will not cause the stack to fail. It would take two or more points of failure to break the stack apart.

Note: If a stack breaks apart, the IP address will be the same for any

common VLANs (with active port connections) that appear in both stack segments.

IP Interface for Stack Management

The stack functions as one integral system for management and configuration purposes. You can therefore manage the stack through any unit in the stack. The Master unit does not even have to include an active port member in the VLAN interface used for management access. However, if the unit to which you normally connect for management access fails, and there are no active port members on the other units within this VLAN interface, then this IP address will no longer be available. To retain a constant IP address for management access across fail over events, you should include port members on several units within the primary VLAN used for stack management.

2-7

NITIAL CONFIGURATION

Resilient Configuration

If a unit in the stack fails, the unit numbers will not change. This means that when you replace a unit in the stack, the original configuration for the failed unit will be restored to the replacement unit. This applies to both the Master and Slave units.

Renumbering the Stack

The startup configuration file maps configuration settings to each switch in the stack based on the unit identification number. If the units are no longer numbered sequentially after several topology changes or failures, you can reset the unit numbers using the “Renumbering” command in the web interface or CLI. Just remember to save the new configuration settings to a startup configuration file prior to powering off the stack Master.

Basic Configuration

Console Connection

The CLI program provides two different command levels — normal access level (Normal Exec) and privileged access level (Privileged Exec). The commands available at the Normal Exec level are a limited subset of those available at the Privileged Exec level and only allow you to display information and use basic utilities. To fully configure the switch parameters, you must access the CLI at the Privileged Exec level.

Access to both CLI levels are controlled by user names and passwords. The switch has a default user name and password for each level. To log into the CLI at the Privileged Exec level using the default user name and password, perform these steps:

1. To initiate your console connection, press <Enter>. The “User Access

Verification” procedure starts.

2. At the Username prompt, enter “admin.”

2-8

ASIC CONFIGURATION

3. At the Password prompt, also enter “admin.” (The password characters are not displayed on the console screen.)

4. The session is opened and the CLI displays the “Console#” prompt indicating you have access at the Privileged Exec level.

Setting Passwords

Note: If this is your first time to log into the CLI program, you should

define new passwords for both default user names using the “username” command, record them and put them in a safe place.

Passwords can consist of up to 8 alphanumeric characters and are case sensitive. To prevent unauthorized access to the switch, set the passwords as follows:

1. Open the console interface with the default user name and password “admin” to access the Privileged Exec level.

2. Type “configure” and press <Enter>.

3. Type “username guest password 0 password,” for the Normal Exec level, where password is your new password. Press <Enter>.

4. Type “username admin password 0 password,” for the Privileged Exec level, where password is your new password. Press <Enter>.

Username: admin Password:

CLI session with the SMC8748M is opened. To end the CLI session, enter [Exit].

Console#configure Console(config)#username guest password 0 [password] Console(config)#username admin password 0 [password] Console(config)#

2-9

NITIAL CONFIGURATION

Setting an IP Address

You must establish IP address information for the switch to obtain management access through the network. This can be done in either of the following ways:

Manual — You have to input the information, including IP address and subnet mask. If your management station is not in the same IP subnet as the switch, you will also need to specify the default gateway router.

Dynamic — The switch sends IP configuration requests to BOOTP or DHCP address allocation servers on the network.

Manual Configuration

You can manually assign an IP address to the switch. You may also need to specify a default gateway that resides between this device and management stations on another network segment. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the CLI program.

Note: The IP address for this switch is obtained via DHCP by default.

Before you can assign an IP address to the switch, you must obtain the following information from your network administrator:

• IP address for the switch

• Default gateway for the network

• Network mask for this network

To assign an IP address to the switch, complete the following steps:

1. From the Privileged Exec level global configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.

2. Type “ip address ip-address netmask,” where “ip-address” is the switch IP address and “netmask” is the network mask for the network. Press <Enter>.

2-10

ASIC CONFIGURATION

3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.

4. To set the IP address of the default gateway for the network to which the switch belongs, type “ip default-gateway gateway,” where “gateway” is the IP address of the default gateway. Press <Enter>.

Console(config)#interface vlan 1 Console(config-if)#ip address 192.168.1.5 255.255.255.0 Console(config-if)#exit Console(config)#ip default-gateway 192.168.1.254 Console(config)#

Dynamic Configuration

If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp restart” command to start broadcasting service requests. Requests will be sent periodically in an effort to obtain IP configuration information. (BOOTP and DHCP values can include the IP address, subnet mask, and default gateway.)

If the “bootp” or “dhcp” option is saved to the startup-config file (step 6), then the switch will start broadcasting service requests as soon as it is powered on.

To automatically configure the switch by communicating with BOOTP or DHCP address allocation servers on the network, complete the following steps:

1. From the Global Configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.

2. At the interface-configuration mode prompt, use one of the following commands:

• To obtain IP settings via DHCP, type “ip address dhcp” and press <Enter>.

2-11

NITIAL CONFIGURATION

• To obtain IP settings via BOOTP, type “ip address bootp” and press <Enter>.

3. Type “end” to return to the Privileged Exec mode. Press <Enter>.

4. Type “ip dhcp restart” to begin broadcasting service requests. Press <Enter>.

5. Wait a few minutes, and then check the IP configuration settings by typing the “show ip interface” command. Press <Enter>.

6. Then save your configuration changes by typing “copy running-config startup-config.” Enter the startup file name and press <Enter>.

Console(config)#interface vlan 1 Console(config-if)#ip address dhcp Console(config-if)#end Console#ip dhcp restart Console#show ip interface IP address and netmask: 192.168.1.54 255.255.255.0 on VLAN 1, and address mode: User specified. Console#copy running-config startup-config Startup configuration file name []: startup \Write to FLASH Programming.

\Write to FLASH finish. Success.

Enabling SNMP Management Access

The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as SMC EliteView. You can configure the switch to (1) respond to SNMP requests or (2) generate SNMP traps.

When SNMP management stations send requests to the switch (either to return information or to set a parameter), the switch provides the requested data or sets the specified parameter. The switch can also be configured to send information to SNMP managers (without being requested by the managers) through trap messages, which inform the manager that certain events have occurred.

2-12

ASIC CONFIGURATION

The switch includes an SNMP agent that supports SNMP version 1, 2c, and 3 clients. To provide management access for version 1 or 2c clients, you must specify a community string. The switch provides a default MIB View (i.e., an SNMPv3 construct) for the default “public” community string that provides read access to the entire MIB tree, and a default view for the “private” community string that provides read/write access to the entire MIB tree. However, you may assign new views to version 1 or 2c community strings that suit your specific security requirements (see page 3-56).

Community Strings (for SNMP version 1 and 2c clients)

Community strings are used to control management access to SNMP version 1 and 2c stations, as well as to authorize SNMP stations to receive trap messages from the switch. You therefore need to assign community strings to specified users, and set the access level.

The default strings are:

• public - with read-only access. Authorized management stations are only able to retrieve MIB objects.

• private - with read-write access. Authorized management stations are able to both retrieve and modify MIB objects.

To prevent unauthorized access to the switch via SNMP version 1 or 2c clients, it is recommended that you change the default community strings.

To configure a community string, complete the following steps:

1. From the Privileged Exec level global configuration mode prompt,

type “snmp-server community string mode,” where “string” is the community access string and “mode” is rw (read/write) or ro (read only). Press <Enter>. (Note that the default mode is read only.)

2. To remove an existing string, simply type “no snmp-server community

string,” where “string” is the community access string to remove. Press <Enter>.

2-13

NITIAL CONFIGURATION

Console(config)#snmp-server community admin rw Console(config)#snmp-server community private Console(config)#

Note: If you do not intend to support access to SNMP version 1 and 2c

clients, we recommend that you delete both of the default community strings. If there are no community strings, then SNMP management access from SNMP v1 and v2c clients is disabled.

Trap Receivers

You can also specify SNMP stations that are to receive traps from the switch. To configure a trap receiver, use the “snmp-server host” command. From the Privileged Exec level global configuration mode prompt, type:

“snmp-server host host-address community string [version {1|2c|3 {auth|noauth|priv}}]

where “host-address” is the IP address for the trap receiver and “community-string” specifies access rights for a version 1/2c host, or is the user name of a version 3 host, “version” indicates the SNMP client version, and “auth|noauth|priv” means that authentication, no authentication, or authentication and privacy is used for v3 clients. Then press <Enter>. For a more detailed description of these parameters, “snmp-server host” on page 4-151 The following example creates a trap

host for each type of SNMP client.

Console(config)#snmp-server host 10.1.19.23 batman Console(config)#snmp-server host 10.1.19.98 robin version 2c Console(config)#snmp-server host 10.1.19.34 barbie version 3 auth

Configuring Access for SNMP Version 3 Clients

To configure management access for SNMPv3 clients, you need to first create a view that defines the portions of MIB that the client can read or write, assign the view to a group, and then assign the user to a group. The following example creates one view called “mib-2” that includes the entire

2-14

ASIC CONFIGURATION

MIB-2 tree branch, and then another view that includes the IEEE 802.1D bridge MIB. It assigns these respective read and read/write views to a group called “r&d” and specifies group authentication via MD5 or SHA. In the last step, it assigns a v3 user to this group, indicating that MD5 will be used for authentication, provides the password “greenpeace” for

authentication, and the password “einstein” for encryption.

Console(config)#snmp-server view mib-2 1.3.6.1.2.1 included Console(config)#snmp-server view 802.1d 1.3.6.2.1.17 included Console(config)#snmp-server group r&d v3 auth read mib-2 write 802.1d Console(config)#snmp-server user steve r&d v3 auth md5 greenpeace

For a more detailed explanation on how to configure the switch for access from SNMP v3 clients, refer to “Simple Network Management Protocol” on page 3-45, or refer to the specific CLI commands for SNMP starting on page 4-146.

Saving Configuration Settings

Configuration commands only modify the running configuration file and are not saved when the switch is rebooted. To save all your configuration changes in nonvolatile storage, you must copy the running configuration to the start-up configuration file using the “copy” command.

To save the current configuration settings, enter the following command:

1. From the Privileged Exec level global configuration mode prompt,

type “copy running-config startup-config” and press <Enter>.

2. Enter the name of the start-up file. Press <Enter>.

Console#copy running-config startup-config Startup configuration file name []: startup \Write to FLASH Programming. \Write to FLASH finish. Success. Console#

NITIAL CONFIGURATION

Managing System Files

The switch’s flash memory supports three types of system files that can be managed by the CLI program, Web interface, or SNMP. The switch’s file system allows files to be uploaded and downloaded, copied, deleted, and set as a start-up file.

The three types of files are:

• Configuration — This file stores system configuration information and is created when configuration settings are saved. Saved configuration files can be selected as a system start-up file or can be uploaded via TFTP to a server for backup. A file named “Factory_Default_Config.cfg” contains all the system default settings and cannot be deleted from the system. See “Saving or Restoring Configuration Settings” on page 3-25 for more information.

• Operation Code — System software that is executed after boot-up, also known as run-time code. This code runs the switch operations and provides the CLI and Web management interfaces. See “Managing Firmware” on page 3-22 for more information.

• Diagnostic Code — Software that is run during system boot-up, also known as POST (Power On Self-Test).

Due to the size limit of the flash memory, the switch supports only two operation code files. However, you can have as many diagnostic code files and configuration files as available flash memory space allows.

In the system flash memory, one file of each type must be set as the start-up file. During a system boot, the diagnostic and operation code files set as the start-up file are run, and then the start-up configuration file is loaded.

2-16

ANAGING SYSTEM FILES

Note that configuration files should be downloaded using a file name that reflects the contents or usage of the file settings. If you download directly to the running-config, the system will reboot, and the settings will have to be copied from the running-config to a permanent file.

WITCH

Using the Web Interface

This switch provides an embedded HTTP web agent. Using a web browser you can configure the switch and view statistics to monitor network activity. The Web agent can be accessed by any computer on the network using a standard web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above).

Note: You can also use the Command Line Interface (CLI) to manage

the switch over a serial connection to the console port or via Telnet. For more information on using the CLI, refer to Chapter 4 “Command Line Interface.”

Prior to accessing the switch from a Web browser, be sure you have first performed the following tasks:

1. Configure the switch with a valid IP address, subnet mask, and default gateway using an out-of-band serial connection, BOOTP or DHCP protocol. (See “Setting an IP Address” on page 2-10.)

2. Set user names and passwords using an out-of-band serial connection. Access to the Web agent is controlled by the same user names and passwords as the onboard configuration program. (See “Setting Passwords” on page 2-9.)

3. After you enter a user name and password, you will have access to the system configuration program.

3-1

ONFIGURING THE SWITCH

Notes: 1. You are allowed three attempts to enter the correct password;

on the third failed attempt the current connection is terminated.

2. If you log into the Web interface as guest (Normal Exec level), you can view the configuration settings or change the guest password. If you log in as “admin” (Privileged Exec level), you can change the settings on any page.

3. If the path between your management station and this switch does not pass through any device that uses the Spanning Tree Algorithm, then you can set the switch port attached to your management station to fast forwarding (i.e., enable Admin Edge Port) to improve the switch’s response time to management commands issued through the web interface. See “Configuring Interface Settings” on page 3-153.

AVIGATING THE WEB BROWSER INTERFACE

Navigating the Web Browser Interface

To access the web-browser interface you must first enter a user name and password. The administrator has Read/Write access to all configuration parameters and statistics. The default user name and password for the administrator is “admin.”

Home Page

When your web browser connects with the switch’s web agent, the home page is displayed as shown below. The home page displays the Main Menu on the left side of the screen and System Information on the right side. The Main Menu links are used to navigate to other menus, and display configuration parameters and statistics.

ONFIGURING THE SWITCH

Setting the Switch’s IP Address

This section describes how to configure an IP interface for management access over the network. The IP address for this switch is obtained via DHCP by default. To manually configure an address, you need to change the switch’s default settings (IP address 0.0.0.0 and netmask 255.0.0.0) to values that are compatible with your network. You may also need to a establish a default gateway between the switch and management stations that exist on another network segment.

You can manually configure a specific IP address, or direct the device to obtain an address from a BOOTP or DHCP server. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the CLI program.

Command Attributes

•Management VLAN – ID of the configured VLAN (1-4093, no

leading zeroes). By default, all ports on the switch are members of VLAN 1. However, the management station can be attached to a port belonging to any VLAN, as long as that VLAN has been assigned an IP address.

• IP Address Mode – Specifies whether IP functionality is enabled via manual configuration (Static), Dynamic Host Configuration Protocol (DHCP), or Boot Protocol (BOOTP). If DHCP/BOOTP is enabled, IP will not function until a reply has been received from the server. Requests will be broadcast periodically by the switch for an IP address. (DHCP/BOOTP values can include the IP address, subnet mask, and default gateway.)

• IP Address – Address of the VLAN interface that is allowed management access. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. (Default: 0.0.0.0)

• Subnet Mask – This mask identifies the host address bits used for routing to specific subnets. (Default: 255.0.0.0)

3-18

ASIC CONFIGURATION

• Default Gateway – IP address of the gateway router between this device and management stations that exist on other network segments. (Default: 0.0.0.0)

• MAC Address – The physical layer address for this switch.

Manual Configuration

Web – Click System, IP Configuration. Select the VLAN through which

the management station is attached, set the IP Address Mode to “Static,” enter the IP address, subnet mask and gateway, then click Apply.

Figure 3-6 Manual IP Configuration

CLI – Specify the management interface, IP address and default gateway.

ONFIGURING THE SWITCH

Using DHCP/BOOTP

If your network provides DHCP/BOOTP services, you can configure the switch to be dynamically configured by these services.

Web – Click System, IP Configuration. Specify the VLAN to which the management station is attached, set the IP Address Mode to DHCP or BOOTP. Click Apply to save your changes. Then click Restart DHCP to immediately request a new address. Note that the switch will also broadcast a request for IP configuration settings on each power reset.

Figure 3-7 DHCP IP Configuration

Note: If you lose your management connection, use a console

connection and enter “show ip interface” to determine the new switch address.

3-20

ASIC CONFIGURATION

CLI – Specify the management interface, and set the IP address mode to DHCP or BOOTP, and then enter the “ip dhcp restart” command.

Console#config Console(config)#interface vlan 1 4-174 Console(config-if)#ip address dhcp 4-288 Console(config-if)#end Console#ip dhcp restart 4-289 Console#show ip interface 4-291 IP address and netmask: 192.168.1.54 255.255.255.0 on VLAN 1, and address mode: dhcp Console#

Renewing DCHP – DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to another network segment, you will lose management access to the switch. In this case, you can reboot the switch or submit a client request to restart DHCP service via the CLI.

Web – If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the web interface. You can only restart DHCP service via the web interface if the current address is still available.

CLI – Enter the following command to restart DHCP service.

Console#ip dhcp restart 4-289 Console#

ASIC CONFIGURATION

Configuring Event Logging

The switch allows you to control the logging of error messages, including the type of events that are recorded in switch memory, logging to a remote System Log (syslog) server, and displays a list of recent event messages.

System Log Configuration

The system allows you to enable or disable event logging, and specify which levels are logged to RAM or flash memory.

Severe error messages that are logged to flash memory are permanently stored in the switch to assist in troubleshooting network problems. Up to 4096 log entries can be stored in the flash memory, with the oldest entries being overwritten first when the available log memory (256 kilobytes) has been exceeded.

The System Logs page allows you to configure and limit system messages that are logged to flash or RAM memory. The default is for event levels 0 to 3 to be logged to flash and levels 0 to 7 to be logged to RAM.

Command Attributes

• System Log Status – Enables/disables the logging of debug or error messages to the logging process. (Default: Enabled)

• Flash Level – Limits log messages saved to the switch’s permanent flash memory for all levels up to the specified level. For example, if level 3 is specified, all messages from level 0 to level 3 will be logged to flash. (Range: 0-7, Default: 3)

Remote Log Configuration

The Remote Logs page allows you to configure the logging of messages that are sent to syslog servers or other management stations. You can also limit the event messages sent to only those messages at or above a specified level.

Command Attributes

• Remote Log Status – Enables/disables the logging of debug or error messages to the remote logging process. (Default: Disabled)

• Logging Facility – Sets the facility type for remote logging of syslog messages. There are eight facility types specified by values of 16 to 23. The facility type is used by the syslog server to dispatch log messages to an appropriate service.

The attribute specifies the facility type tag sent in syslog messages. (See RFC 3164.) This type has no effect on the kind of messages reported by the switch. However, it may be used by the syslog server to process messages, such as sorting or storing messages in the corresponding database. (Range: 16-23, Default: 23)

• Logging Trap – Limits log messages that are sent to the remote syslog server for all levels up to the specified level. For example, if level 3 is specified, all messages from level 0 to level 3 will be sent to the remote server. (Range: 0-7, Default: 7)

• Host IP List – Displays the list of remote server IP addresses that will receive syslog messages. The maximum number of host IP addresses allowed is five.

Sending Simple Mail Transfer Protocol Alerts

To alert system administrators of problems, the switch can use SMTP (Simple Mail Transfer Protocol) to send email messages when triggered by logging events of a specified level. The messages are sent to specified SMTP servers on the network and can be retrieved using POP or IMAP clients.

3-37

ONFIGURING THE SWITCH

Command Attributes

• Admin Status – Enables/disables the SMTP function. (Default: Enabled)

• Email Source Address – Sets the email address used for the “From” field in alert messages. You may use a symbolic email address that identifies the switch, or the address of an administrator responsible for the switch.

• Severity – Sets the syslog severity threshold level (see Table 3-3) used to trigger alert messages. All events at this level or higher will be sent to the configured email recipients. For example, using Level 7 will report all events from level 7 to level 0. (Default: Level 7)

• SMTP Server List – Specifies a list of up to three recipient SMTP servers. The switch attempts to connect to the other listed servers if the first fails. Use the New SMTP Server text field and the Add/Remove buttons to configure the list.

Renumbering the Stack

If the units are no longer numbered sequentially after several topology changes or failures, you can reset the unit numbers using the “Renumbering” command. Just remember to save the new configuration settings to a startup configuration file prior to powering off the stack Master.

Command Usage

• The startup configuration file maps configuration settings to each switch in the stack based on the unit identification number. You should

therefore remember to save the current configuration after renumbering the stack.

• For a line topology, the stack is numbered from top to bottom, with the first unit (i.e., the unit with no connection on the Up port) in the stack designated as unit 1. For a ring topology, the Master unit taken as the top of the stack and is numbered as unit 1 and all other units are numbered sequentially down through the ring.

Web – Click System, Renumbering.

ONFIGURING THE SWITCH

Setting the System Clock

Simple Network Time Protocol (SNTP) allows the switch to set its internal clock based on periodic updates from a time server (SNTP or NTP). Maintaining an accurate time on the switch enables the system log to record meaningful dates and times for event entries. You can also manually set the clock using the CLI. (See “calendar set” on page 4-74.) If the clock is not set, the switch will only record the time from the factory default set at the last bootup.

When the SNTP client is enabled, the switch periodically sends a request for a time update to a configured time server. You can configure up to three time server IP addresses. The switch will attempt to poll each server in the configured sequence.

Configuring SNTP

You can configure the switch to send time synchronization requests to specific time servers.

Command Attributes

• SNTP Client – Configures the switch to operate as an SNTP unicast client. This mode requires at least one time server to be specified in the SNTP Server field.

• SNTP Poll Interval – Sets the interval between sending requests for a time update from a time server when set to SNTP Client mode. (Range: 16-16284 seconds; Default: 16)

• SNTP Server – Sets the IP address for up to three time servers. The switch attempts to update the time from the first server, if this fails it attempts an update from the next server in the sequence.

Setting the Time Zone

SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours and minutes your time zone is east (before) or west (after) of UTC.

Command Attributes

• Current Time – Displays the current time.

• Name – Assigns a name to the time zone. (Range: 1-29 characters)

• Hours (0-13) – The number of hours before/after UTC.

3-43

ONFIGURING THE SWITCH

• Minutes (0-59) – The number of minutes before/after UTC.
