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. Storm suppression prevents broadcast, multicast or unknown unicast traffic storms from engulfing the network. Port-based, protocol based and private 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.

Other authentication options include HTTPS for secure management access via the web, SSH for secure management access over a Telnet-equivalent connection, SNMP Version 3, IP address filtering for SNMP/web/Telnet management access. MAC address filtering and IP source guard also provide authenticated port access. While DHCP snooping is provided to prevent malicious attacks from insecure ports.

Access Control Lists – ACLs provide packet filtering for IP frames (based on address, protocol, Layer 4 protocol port number or TCP control code) or any frames (based on MAC address or Ethernet type). ACLs can be used to improve performance by blocking unnecessary network traffic or to implement security controls by restricting access to specific network resources or protocols.

Description of Software Features

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 packets when port buffer thresholds are exceeded. The switch supports flow control based on the IEEE 802.3x standard (now incorporated in IEEE 802.3-2002).

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. 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.

RSPAN Mirroring – You can configure the switch to mirror traffic from remote switches over a dedicated VLAN. The traffic mirrored can be analyzed in the same way you would when mirroring traffic locally on a switch.

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

Storm Control – Broadcast, multicast and unknown unicast storm suppression prevents traffic from overwhelming the network. When enabled on a port, the level of traffic passing through the port is restricted. If 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.

IP Address Filtering – Access to insecure ports can be controlled using DHCP Snooping which filters ingress traffic based on static IP addresses and addresses stored in the DHCP Snooping table. Traffic can also be restricted to specific source IP addresses or source IP/MAC address pairs based on static entries or entries stored in the DHCP Snooping table.

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 8K 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

1-3

Introduction

(CRC). This prevents bad frames from entering the network and wasting bandwidth.

To avoid dropping frames on congested ports, the switch provides 4 Mbits 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 Protocol (STP, IEEE 802.1D) – This protocol provides loop detection and recovery by allowing two or more redundant connections to be created between a pair of LAN segments. 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 802.1D-2004) – This protocol reduces the convergence time for network topology changes to 3 to 5 seconds, compared to 30 seconds or more for the older IEEE 802.1D STP standard. It is intended as a complete replacement for STP, but can still interoperate with switches running the older standard by automatically reconfiguring ports to STP-compliant mode if they detect STP protocol messages from attached devices.

Multiple Spanning Tree Protocol (MSTP, IEEE 802.1D-2004) – 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 prevents VLAN members from being segmented from the rest of the group (as sometimes occurs with IEEE 802.1D STP).

Virtual LANs – The switch supports up to 256 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.

• 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 VLANs to restrict traffic to specified interfaces based on protocol type.

Note: The switch allows 255 user-manageable VLANs. One other VLAN (VLAN ID 4093)

is reserved for switch clustering.

Description of Software Features

Traffic Prioritization – This switch prioritizes each packet based on the required level of service, using four 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 independent priorities for delay-sensitive data and best-effort data.

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

Quality of Service – Differentiated Services (DiffServ) provides policy-based management mechanisms used for prioritizing network resources to meet the requirements of specific traffic types on a per-hop basis. Each packet is classified upon entry into the network based on access lists, IP Precedence or DSCP values, or VLAN lists. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained in each packet. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding.

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. It also supports Multicast VLAN Registration (MVR) which allows common multicast traffic, such as television channels, to be transmitted across a single network-wide multicast VLAN shared by hosts residing in other standard or private VLAN groups, while preserving security and data isolation for normal traffic.

be used to provide

IEEE 802.1Q Tunneling (QinQ) – This feature is designed for service providers carrying traffic for multiple customers across their networks. QinQ tunneling is used to maintain customer-specific VLAN and Layer 2 protocol configurations even when different customers use the same internal VLAN IDs. This is accomplished by inserting Service Provider VLAN (SPVLAN) tags into the customer’s frames when they enter the service provider’s network, and then stripping the tags when the frames leave the network.

Chapter 2: Initial Configuration

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 2-4.

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 Internet Explorer 5.x or above, Netscape 6.2 or above, and Mozilla Firefox 2.0.0.0 or above. 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 or Secure Shell (SSH) 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’s EliteView.

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 a management VLAN

• Configure SNMP parameters

• Enable/disable any port

• Set the speed/duplex mode for any port

• Configure the bandwidth of any port by limiting input rates

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

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.

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 RS-232 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 the following baud rates: 9600, 19200, 38400, 57600, 115200 (Note: Set to 9600 baud if want to view all the 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.

• When using HyperTerminal, select Terminal keys, not Windows keys.

Notes: 1. Refer to "Line Commands" on page 4-31 for a complete description of

Basic Configuration

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 obtained 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 2-4.

Note: This switch supports four concurrent Telnet/SSH sessions.

After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network. The switch’s command-line interface can be accessed using Telnet or SSH from any computer attached to the network. The switch can also be managed by any computer using a web browser (Internet Explorer 5.x or above, or Netscape 6.2 or above, or Mozilla Firefox 2.0.0.0), 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.

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 allow you to only 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.”

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.

2-3

Initial Configuration

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>.

Note: ‘0’ specifies a password in plain text, ‘7’ specifies the password in encrypted form.

Username: admin Password:

CLI session with the SMC8126PL2-F 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)#

Setting an IP Address

You must establish IP address information for the stack 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 stack’s master unit, 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 that exist 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.

2-4

Basic Configuration

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 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>.

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. 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 DHCP/BOOTP server is slow to respond, you may need to use the “ip dhcp restart” command to re-start broadcasting service requests.

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>.

• 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>.

2-5

Initial Configuration

4. If network connections are normally slow, type “ip dhcp restart” to re-start 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 4-155 Console(config-if)#ip address dhcp 4-297 Console(config-if)#end Console#ip dhcp restart Console#show ip interface 4-299 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 4-25 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.

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 3-52).

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.

2-6

Basic Configuration

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 from 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>.

Console(config)#snmp-server community admin rw 4-63 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, “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, see "snmp-server host" on page 4-65. The following example creates a trap host for each type of SNMP client.

Console(config)#snmp-server host 10.1.19.23 batman 4-65 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 Console(config)#

2-7

Initial Configuration

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 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 call “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 “einstien” for encryption.

Console(config)#snmp-server view mib-2 1.3.6.1.2.1 included 4-69 Console(config)#snmp-server view 802.1d 1.3.6.1.2.1.17 included Console(config)#snmp-server group r&d v3 auth mib-2 802.1d 4-71 Console(config)#snmp-server user steve group r&d v3 auth md5

Console(config)#

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 3-37, or refer to the specific CLI commands for SNMP starting on page 4-61.

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 type 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. The file named “Factory_Default_Config.cfg” contains all the system default settings and cannot be deleted from the system. If the system is booted with the factory default settings, the switch will also create a file named “startup1.cfg” that contains system settings for initialization, including information about the unit identifier, MAC address, and installed module type. The configuration settings from the factory defaults configuration file are copied to this file, which is then used to boot the switch. See "Saving or Restoring Configuration Settings" on page 3-22 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 3-20 for more information.

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

2-8

Managing System Files

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. The switch has a total of 16 Mbytes of flash memory for system files.

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.

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.

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 file to the start-up configuration file using the “copy” command.

New startup configuration files must have a name specified. File names on the switch are case-sensitive, can be from 1 to 31 characters, must not contain slashes (\ or /), and the leading letter of the file name must not be a period (.). (Valid characters: A-Z, a-z, 0-9, “.”, “-”, “_”)

There can be more than one user-defined configuration file saved in the switch’s flash memory, but only one is designated as the “startup” file that is loaded when the switch boots. The copy running-config startup-config command always sets the new file as the startup file. To select a previously saved configuration file, use the boot system config:<filename> command.

The maximum number of saved configuration files depends on available flash memory, with each configuration file normally requiring less than 20 kbytes. The amount of available flash memory can be checked by using the dir command.

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

1. From the Privileged Exec 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 4-25 Startup configuration file name []: startup \Write to FLASH Programming.

Chapter 3: Configuring the Switch

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, Netscape 6.2 or above, or Mozilla Firefox 2.0.0.0 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 2-4.)

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 2-4.)

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

configuration program.

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 for STA" on page 3-154.

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 the stack is obtained via DHCP by default. To manually configure an address, you need to change the switch’s default settings to values that are compatible with your network. You may also need to a establish a default gateway between the stack 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 (1-4094). 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 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)

• Gateway IP address – 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.

• Restart DHCP – Requests a new IP address from the DHCP server.

3-16

Basic Configuration

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.

Configuring 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.

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

3-18

Basic Configuration

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 4-299 Console#

Enabling Jumbo Frames

The switch provides more efficient throughput for large sequential data transfers by supporting jumbo frames up to 10 KB for the Gigabit Ethernet ports. Compared to standard Ethernet frames that run only up to 1.5 KB, using jumbo frames significantly reduces the per-packet overhead required to process protocol encapsulation fields.

Command Usage

• To use jumbo frames, both the source and destination end nodes (such as a

computer or server) must support this feature. Also, when the connection is operating at full duplex, all switches in the network between the two end nodes must be able to accept the extended frame size. And for half-duplex connections, all devices in the collision domain would need to support jumbo frames.

• Enabling jumbo frames will limit the maximum threshold for broadcast storm

control to 64 packets per second. (See "Setting Broadcast Storm Thresholds" on page 3-127.)

Command Attributes

Jumbo Packet Status – Check the box to enable jumbo frames.

Web – Click System, Jumbo Frames. Enable or disable support for jumbo frames,

and click Apply.

Configuring the Switch

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 error messages sent to only those messages below 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 receive the

syslog messages. The maximum number of host IP addresses allowed is five.

Basic Configuration

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 4-55) 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.

Setting the Time Manually

You can set the system time on the switch manually without using SNTP.

CLI – This example sets the system clock time and then displays the current time and date

Configuring SNTP

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

Command Attributes

Simple Network Management Protocol

Simple Network Management Protocol (SNMP) is a communication protocol designed specifically for managing devices on a network. Equipment commonly managed with SNMP includes switches, routers and host computers. SNMP is typically used to configure these devices for proper operation in a network environment, as well as to monitor them to evaluate performance or detect potential problems.

Managed devices supporting SNMP contain software, which runs locally on the device and is referred to as an agent. A defined set of variables, known as managed objects, is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB) that provides a standard presentation of the information controlled by the agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network.

The switch includes an onboard agent that supports SNMP versions 1, 2c, and 3. This agent continuously monitors the status of the switch hardware, as well as the traffic passing through its ports. A network management station can access this information using software such as SMC EliteView. Access to the onboard agent from clients using SNMP v1 and v2c is controlled by community strings. To communicate with the switch, the management station must first submit a valid community string for authentication.

3-37

Configuring the Switch

Access to the switch using from clients using SNMPv3 provides additional security features that cover message integrity, authentication, and encryption; as well as controlling user access to specific areas of the MIB tree.

The SNMPv3 security structure consists of security models, with each model having it’s own security levels. There are three security models defined, SNMPv1, SNMPv2c, and SNMPv3. Users are assigned to “groups” that are defined by a security model and specified security levels. Each group also has a defined security access to set of MIB objects for reading and writing, which are known as “views.” The switch has a default view (all MIB objects) and default groups defined for security models v1 and v2c. The following table shows the security models and levels available and the system default settings.

Setting Community Access Strings

You may configure up to five community strings authorized for management access by clients using SNMP v1 and v2c. All community strings used for IP Trap Managers should be listed in this table. For security reasons, you should consider removing the default strings.

Command Attributes

• SNMP Community Capability – The switch supports up to five community strings.

• Current – Displays a list of the community strings currently configured.

• Community String – A community string that acts like a password and permits

access to the SNMP protocol. Default strings: “public” (read-only), “private” (read/write) Range: 1-32 characters, case sensitive

• Access Mode

- Read-Only – Authorized management stations are only able to retrieve MIB objects.

- Read/Write – Authorized management stations are able to both retrieve and modify MIB objects.

Web – Click SNMP, Configuration. Add new community strings as required, select the access rights from the Access Mode drop-down list, then click Add.

Figure 3-25 Configuring SNMP Community Strings

CLI – The following example adds the string “spiderman” with read/write access.

Console(config)#snmp-server community spiderman rw 4-63 Console(config)#

Specifying Trap Managers and Trap Types

Traps indicating status changes are issued by the switch to specified trap managers. You must specify trap managers so that key events are reported by this switch to your management station (using network management platforms such as SMC EliteView). You can specify up to five management stations that will receive authentication failure messages and other trap messages from the switch.

Command Usage

• If you specify an SNMP Version 3 host, then the “Trap Manager Community String” is interpreted as an SNMP user name. If you use V3 authentication or encryption options (authNoPriv or authPriv), the user name must first be defined in the SNMPv3 Users page (3-45). Otherwise, the authentication password and/or privacy password will not exist, and the switch will not authorize SNMP access for the host. However, if you specify a V3 host with the no authentication (noAuth) option, an SNMP user account will be automatically generated, and the switch will authorize SNMP access for the host.

• Notifications are issued by the switch as trap messages by default. The recipient of a trap message does not send a response to the switch. Traps are therefore not as reliable as inform messages, which include a request for acknowledgement of receipt. Informs can be used to ensure that critical information is received by the host. However, note that informs consume more system resources because they must be kept in memory until a response is received. Informs also add to network traffic. You should consider these effects when deciding whether to issue notifications as traps or informs.

3-40

Simple Network Management Protocol

To send an inform to a SNMPv2c host, complete these steps:

1. Enable the SNMP agent (3-39).

2. Enable trap informs as described in the following pages.

3. Create a view with the required notification messages (3-52).

4. Create a group that includes the required notify view (3-49).

To send an inform to a SNMPv3 host, complete these steps:

1. Enable the SNMP agent (3-39).

2. Enable trap informs as described in the following pages.

3. Create a view with the required notification messages (3-52).

4. Create a group that includes the required notify view (3-49).

5. Specify a remote engine ID where the user resides (3-44).

6. Then configure a remote user (3-47).

• Trap Manager Capability – This switch supports up to five trap managers.

• Current – Displays a list of the trap managers currently configured.

• Trap Manager IP Address – IP address of a new management station to receive

notification message (i.e., the targeted recipient).

• Trap Manager Community String – Specifies a valid community string for the

new trap manager entry. Though you can set this string in the Trap Managers table, we recommend that you define this string in the SNMP Community section at the top of the SNMP Configuration page (for Version 1 or 2c clients), or define a corresponding “User Name” in the SNMPv3 Users page (for Version 3 clients). (Range: 1-32 characters, case sensitive)

• Trap UDP Port – Specifies the UDP port number used by the trap manager.

(Default: 162)

• Trap Version – Specifies whether to send notifications as SNMP v1, v2c, or v3

traps. (Default: v1)

• Trap Security Level – When trap version 3 is selected, you must specify one of

the following security levels. (Default: noAuthNoPriv)

- noAuthNoPriv – There is no authentication or encryption used in SNMP communications.

- AuthNoPriv – SNMP communications use authentication, but the data is not encrypted (only available for the SNMPv3 security model).

- AuthPriv – SNMP communications use both authentication and encryption (only available for the SNMPv3 security model).

• Trap Inform – Notifications are sent as inform messages. Note that this option is only available for version 2c and 3 hosts. (Default: traps are used)

- Timeout – The number of seconds to wait for an acknowledgment before

resending an inform message. (Range: 0-2147483647 centiseconds; Default: 1500 centiseconds)

- Retry times – The maximum number of times to resend an inform message if

the recipient does not acknowledge receipt. (Range: 0-255; Default: 3)

3-41

Configuring the Switch

• Enable Authentication Traps3 – Issues a notification message to specified IP trap managers whenever an invalid community string is submitted during the SNMP access authentication process. (Default: Enabled)

• Enable Link-up and Link-down Traps whenever a port link is established or broken. (Default: Enabled)

Web – Click SNMP, Configuration. Enter the IP address and community string for each management station that will receive trap messages, specify the UDP port, trap version, trap security level (for v3 clients), trap inform settings (for v2c/v3 clients), and then click Add. Select the trap types required using the check boxes for Authentication and Link-up/down traps, and then click Apply.

Simple Network Management Protocol

Configuring SNMPv3 Management Access

To configure SNMPv3 management access to the switch, follow these steps:

1. If you want to change the default engine ID, it must be changed first before

configuring other parameters.

2. Specify read and write access views for the switch MIB tree.

3. Configure SNMP user groups with the required security model (i.e., SNMP v1,

v2c or v3) and security level (i.e., authentication and privacy).

4. Assign SNMP users to groups, along with their specific authentication and

privacy passwords.

Setting the Local Engine ID

An SNMPv3 engine is an independent SNMP agent that resides on the switch. This engine protects against message replay, delay, and redirection. The engine ID is also used in combination with user passwords to generate the security keys for authenticating and encrypting SNMPv3 packets.

A local engine ID is automatically generated that is unique to the switch. This is referred to as the default engine ID. If the local engine ID is deleted or changed, all SNMP users will be cleared. You will need to reconfigure all existing users.

A new engine ID can be specified by entering 10 to 64 hexadecimal characters.

Web – Click SNMP, SNMPv3, Engine ID. Enter an ID of a least 10 hexadecimal characters and then click Save.

Configuring the Switch

Specifying a Remote Engine ID

To send inform messages to an SNMPv3 user on a remote device, you must first specify the engine identifier for the SNMP agent on the remote device where the user resides. The remote engine ID is used to compute the security digest for authenticating and encrypting packets sent to a user on the remote host.

SNMP passwords are localized using the engine ID of the authoritative agent. For informs, the authoritative SNMP agent is the remote agent. You therefore need to configure the remote agent’s SNMP engine ID before you can send proxy requests or informs to it. (See "Specifying Trap Managers and Trap Types" on page 3-40 and "Configuring Remote SNMPv3 Users" on page 3-47.)

A new engine ID can be specified by entering 10 to 64 hexadecimal characters.

• View OID Subtrees – Shows the currently configured object identifiers of branches within the MIB tree that define the SNMP view.

• Edit OID Subtrees – Allows you to configure the object identifiers of branches within the MIB tree. Wild cards can be used to mask a specific portion of the OID string.

• Type – Indicates if the object identifier of a branch within the MIB tree is included or excluded from the SNMP view.

Web – Click SNMP, SNMPv3, Views. Click New to configure a new view. In the New View page, define a name and specify OID subtrees in the switch MIB to be included or excluded in the view. Click Back to save the new view and return to the SNMPv3 Views list. For a specific view, click on View OID Subtrees to display the current configuration, or click on Edit OID Subtrees to make changes to the view settings.
