Description 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 6K 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 8? MB for frame buffering. This buffer can queue packets awaiting transmission on congested networks.

Spanning Tree Protocol – The switch supports IEEE 802.1D Spanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, the 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.

VLANs – This 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. By segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade performance in a

flat network.

1-2

ESCRIPTION OF SOFTWARE FEATURES

• 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.

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 four trunks, with up to eight up-link ports per trunk.

Broadcast Suppression – 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.

Flow Control – Flow control reduces traffic during periods of congestion and prevent packets from being dropped when port buffers overflow. The switch supports flow control based on the IEEE 802.3x standard. By default, flow control is enabled on all ports.

Tra f f ic Priority – This switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using two priority queues, and processing the high-priority queue before the lowpriority queue, or using Weighted Round Robin Queuing (WRR). It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can be used to provide independent priorities for delay-sensitive data and best-effort data.

1-3

NTRODUCTION

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.

ONFIGURATION

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, and a Web-based interface. A PC may also be connected directly to the switch for configuration and monitoring via the console menu.

Note: The IP address for this switch is unassigned by default. To change

this address, see “Setting an IP Address” on page 2-5.

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 switch’s management agent is based on SNMP (Simple Network Management Protocol). This SNMP agent permits the switch to be managed from any system in the network using management software, such as SMC’s free EliteView software.

The console menu 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 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 network management software such as EliteView.

Notes: 1. Only one management session is supported.

2. 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, such as EliteView.

NITIAL CONFIGURATION

Basic Configuration

Console Connection

Access to the console menu is controlled by a user name and password. The default setting is “admin” for both the user name and password. To log into the console menu, perform these steps:

1. Enter “admin” at the user name prompt.

2. Enter “admin” at the password prompt. (The password characters are not displayed on the console screen.)

The session is opened and the Main Menu displays.

Setting Passwords

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

define a new user name and password, record them and put them in a safe place.

A user name or password can consist of up to 15 alphanumeric characters and are not case sensitive. To prevent unauthorized access to the switch, set the user name and password as follows:

1. Open the console interface with the default user name and password “admin” to access the Main Menu.

2. Navigate from the Main Menu to –

Switch Static Configuration, and then Administration Configuration.

3. Select “Change Username” and press <Enter>.

• Select <Edit>, type in the new user name, and press <Enter>.

4. Select “Change Password” and press <Enter>.

• Type the old password and press <Enter>.

• Type the new password and press <Enter>.

• Then re-enter the new password for verification, press <Enter>.

Setting an IP Address

You must establish IP address information for the switch to obtain management access through the network. 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 configuration program.

Note: The IP address for this switch is unassigned 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

• Network mask for this network

• Default gateway for the network

ASIC CONFIGURATION

Enabling SNMP Management Access

The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as SMC’s EliteView. You also can configure the switch to 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 that inform the manager that certain events have occurred.

Community Strings

Community strings are used to control management access to SNMP 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 or user groups, and set the access level.

The default string is “public” with read-only access. Authorized management stations are only able to retrieve MIB objects.

Note: If you do not intend to use SNMP, it is recommended that you

delete all community strings. If there are no community strings, then SNMP management access to the switch is disabled.

To configure a community string, complete the following steps:

1. Navigate from the Main Menu to –

Protocol Related Configuration, SNMP, and then Community Strings.

2. Click <Add>, then <Edit>.

3. Type in the Community Name, and press <Enter>.

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 console menu to manage the switch over a

serial connection to the console port or via Telnet. For more information on using the console menu, refer to Chapter 4, “Console 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. (See “Setting an IP Address” on page 2-5.)

2. Set a user name and password. Access to the Web agent is controlled by the same user name and password as the console 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.

Note: You are allowed three attempts to enter the correct password; on

the third failed attempt the current connection is terminated.

Basic System Information

Use the Switch Settings page to display basic information on the switch, including hardware/firmware version numbers for the main board and management software.

Field Attributes

• Description – Switch model number.

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

• Firmware Version – Version number of runtime code.

• Hardware Version – Hardware version of the main board.

• Default config value version – Default configuration version.

Web – Click Switch Settings

Basic.

Global Switch Settings

Use the Switch Settings, Advanced menu to configure address aging, packet transmit delay, and broadcast storm control.

Command Usage

• Aging Time – The switch stores the addresses of known devices. This information is used to route traffic directly between the inbound and outbound ports. The addresses are learned by monitoring traffic, and stored in the dynamic address table. You can set the aging time after which inactive entries are removed.

• Transmit Delay Bound – Sets the maximum queuing delay.

3-6

LOBAL SWITCH SETTINGS

• Broadcast Storm Control – Broadcast storms may occur when a device on your network is malfunctioning, or if application programs are not well designed or properly configured. If there is too much broadcast traffic on your network, performance can be severely degraded or everything can come to a complete halt. You can protect your network from broadcast storms by setting a maximum threshold for broadcast traffic.

Field Attributes

• MAC Table Address Entry Age-Out Time – The time after which a learned entry is discarded if no new traffic is seen from that address. (Range: 300-765 seconds; Default: 300 seconds)

• Max bridge transmit delay bound control – Limits the time packets can be queued in the switch. If enabled, packets queued beyond the specified time will be dropped. (Range: OFF, 1, 2, 4 seconds; Default: OFF)

• Broadcast Storm Filter Mode – The percentage of a port’s total bandwidth used by broadcast traffic. When broadcast traffic rises above the specified threshold, broadcast packets exceeding that threshold will then be dropped. (Range: OFF, 5, 10, 15, 20, 25%; Default: OFF)

ONFIGURING THE SWITCH

Class of Service Configuration

Class of Service (CoS) allows you to specify which data packets have greater precedence when traffic is buffered in the switch due to congestion. This switch supports CoS with two priority queues for each port. Data packets in a port’s high-priority queue are transmitted before those in the lower-priority queue.

You can set the method used to process priority traffic (i.e., first-in first-out, all high before low, or weighted round-robin), and also map the frame priority tags (i.e., 0 - 7) to the high or low priority queues.

Field Attributes

• First Come First Served – Packets are processed first-in first-out.

• All High before Low – All packets in the high-priority queue are processed before any packets in the low-priority queue.

• Weighted Round Robin – Sets the preference given to packets in the high-priority queue. This specifies the number of high-priority packets sent before one low-priority packet is sent. (Range: 1-7; Default: 2)

• Enable Delay Bound – Limits the queuing time for low-priority packets. Any low-priority packets that exceed the delay bound will be sent. Note that the “Max bridge transmit delay bound control” must be enabled (page 3-6) for the Enable Delay Bound to function. (Range: 0-255 ms; Default: 0 ms)

• QoS Policy (High Priority Levels) – The default priority levels are assigned according to recommendations in the IEEE 802.1p standard. However, you can map the priority levels to the switch’s output queues in any way that benefits application traffic for your own network. (Range: Level 0 - 7; Default: Level 4 - 7)
