Hardware Installation and Network

Topology

Overview

The Intel Express 100BASE-TX Switching Hub is a 5-port Fast Ethernet switch featuring five 100BASE-TX ports and two slots for optional 100BASE-TX or 100BASE-FX media adapters. Each 100 Mbps port supports a Fast Ethernet segment, up to a total of 1024 cached nodes for the switch.

The switch increases the available bandwidth and extends the distance of Fast Ethernet installations by dividing the network into segments and insulating each from the others’ local traffic. Additionally, by configuring a link for full duplex, you can establish a 200 Mbps link between the switch and another switch, server, or workstation. This is especially useful for busy file servers that are accessed by multiple segments.

Data transfer delays are eliminated through the switch’s parallel storeand-forward architecture with direct port-to-port transfer. Selective flow control improves performance by preventing lost packets due to buffer overload.

Page 8

CHAPTER 1 Intel Express 100BASE-TX Switching Hub

Security features include the creation of custom filters and virtual networks (VLANs). You can define any custom filter based on multicast/broadcast, source port, destination port, and destination address. VLAN features include the ability to set broadcast or multicast domains. See Chapter 2 for information on configuring VLANs.

The switch also has a built-in SNMP (Simple Network Management Protocol) agent and can be monitored and controlled through any SNMP-compliant Network Management System (NMS). See page 20 for information on using the switch with an SNMP NMS and getting the switch’s MIB (Management Information Base) file.

Features

• Five RJ-45 Fast Ethernet ports

• Two expansion ports for optional 100BASE-TX or 100BASE-FX media adapters

• Standard 19-inch rack-mount chassis (rack-mount kit included)

• Auto-ranging power supply (automatically adjusts to any voltage between 90 VAC and 264 VAC at 50/60 Hz)

• Full duplex selectable on each port

• Flow control selectable on each port

• 1024 address cache entries

• Custom filtering table

• Serial console port with password protection

• SNMP support (see Appendix A for MIB information)

• Spanning tree protocol support

• Built-in remote monitoring (RMON) support (Group 1)

Hardware Installation and Network TopologyCHAPTER 1

Installation and Setup

1 Install the switch in a rack or on a shelf.

For rack placement, connect the switch to a 19-inch rack using the enclosed rack mount brackets.

For shelf placement, attach the enclosed rubber feet to each corner of the bottom of the switch and place it on a flat, level surface.

2 Plug the switch in and turn the power on.

Plug the switch into an active AC outlet and turn the power on. A built-in power supply automatically adjusts to any outlet providing between 90 VAC and 264 VAC at 50/60 Hz.

NOTE

The switch will only work with 100 Mbps devices. For a 10BASE-T connection, see page 12.

3 Connect the Fast Ethernet devices.

For optimum performance, the Fast Ethernet segments connected to the switch must be configured carefully. Follow these general guidelines:

• Connect only 100 Mbps devices to the switch. The switch will not work with 10 Mbps devices. See page 12 for information on connecting to a 10 Mbps segment.

• Always use Category 5 unshielded twisted-pair (UTP) cable when plugging devices into 100BASE-TX ports.

• Limit the distance between devices connected with UTP cable to 100 meters.

• Use a crossover cable when directly connecting a workstation, server, or another switch to the switch. Use straight-through cables when connecting to a repeating hub or concentrator.

• Configure the network so devices that primarily talk to each other are on the same segment. Each port on the switch is defined as a single Fast Ethernet segment.

4 Is setup complete?

If you’re using the switch as a stand-alone device (not under the control of network management software), you’re done.

If you want to change the default configuration (shown in Appendix A) or manage the switch, continue to Chapter 2.

Page 10

CHAPTER 1 Intel Express 100BASE-TX Switching Hub

NOTE

The default configuration of all ports is half-duplex mode.

To change to full duplex, use the Console Manager. See page 19 for instructions.

Ports on the switch are wired MDI for connection to MDI-X ports using a straight-through UTP cable. See page 9 for more information.

Using the Switch

The switch requires minimal user intervention. It automatically learns the addresses of new stations as they appear, and will relearn addresses dynamically if the network is reconfigured.

Each of the Fast Ethernet ports has six status LEDs. There is a separate bank of four LEDs for the management status.

Port status LEDs

Port LEDs provide information about the port’s configuration and the status of devices connected to the ports.

CHAPTER 1 Intel Express 100BASE-TX Switching Hub

Cabling Requirements

Incorrect cabling is often the cause of network configuration problems. It’s important that you understand cabling requirements before connecting Fast Ethernet devices to the switch.

UTP requirements

The 100BASE-TX Fast Ethernet specification requires you use Category 5 (CAT5) unshielded twisted-pair (UTP) cabling to operate at 100 Mbps per second. If you use lower grade cabling (CAT3 or CAT4), you’ll get a connection, but will soon experience data loss or slow performance.

You’re limited to 100 meters between any two devices with UTP cable. However, you can extend the total diameter by installing a fiber optic media adapter and using fiber optic connections between switches, or between the switch and a router or bridge.

See pages 10–11 if you’re unsure whether your network topology meets these distance limitations.

Fiber optic requirements

The optional 100BASE-FX fiber optic media adapter (Intel product code ESMODFX) lets you use multimode fiber optic cable to connect two switches, or to connect the switch with a router or bridge. The media adapter uses an SC fiber optic connector.

With multimode fiber optic cable, signals can travel up to 412 meters with no repeater when the link is configured at half duplex. If configured at full duplex, the signal can travel up to 2 km.

Page 13

Hardware Installation and Network TopologyCHAPTER 1

Straight-through vs. crossover cables

Ports on the switch are wired MDI so you can use a straight-through cable when connecting to a Fast Ethernet repeating hub port, which is usually wired MDI-X. For direct connection to another MDI port (workstation, server, or another switch), you must use a crossover cable. The pinouts of MDI and MDI-X ports are shown below.

Connector pinouts

Switch or NIC RJ-45 (MDI) Hub RJ-45 (MDI-X)

NOTE

When making your own cables, wires 1 and 2 must be a twisted pair and 3 and 6 must be a twisted pair.

Determining which cable to use

Different switch and repeater manufacturers implement their port configurations differently. The following guidelines are based on the Intel Express 100BASE-TX Switching Hub (switch), the Intel Express 100BASE-TX Stackable Hub (repeater) and the EtherExpress™ family of adapters (server or workstation). These apply to the majority of switches and hubs:

For this connection Use this cable

CHAPTER 1 Intel Express 100BASE-TX Switching Hub

Typical Configurations

Configuring the 100 Mbps workgroup environment

In the 100 Mbps environment, workgroup clients should be connected to a 100 Mbps hub such as the Intel Express 100BASE-TX Stackable Hub. All hub stacks should be connected to the Express Switching Hub. By connecting the hubs to a switching environment, you can extend Fast Ethernet distance limitations.

CHAPTER 1 Intel Express 100BASE-TX Switching Hub

Connecting to a 10 Mbps segment

The Express Switching Hub is a 100 Mbps-only switch. You can’t connect a 10 Mbps device directly to the switch.

The preferred way to connect the segments is by using a bridge, router, or a 100 Mbps uplink module for your 10 Mbps hub (there isn’t a 10 Mbps uplink module available for the Express switching hub). However, this is costly if you don’t already have the equipment. An inexpensive alternative is to connect the segments through a

NOTE

Windows NT* 3.51 doesn’t include the multi-protocol router software by default. You can download it from the Microsoft World Wide Web site.

Several adapters on the market (such as the Intel EtherExpress PRO/ 100 adapter) operate at either 10 or 100 Mbps. By connecting the Express 100BASE-TX Switching Hub to one server adapter at 100 Mbps and your 10BASE-T hub to a separate adapter at 10 Mbps in the same server, you can route traffic from the 10 Mbps segment to the 100 Mbps segment through your Network Operating System (NOS).

If your NOS doesn’t support multi-protocol routing (Windows 95 peer-to-peer and Windows for Workgroups* don’t), you must use a Fast Ethernet switch or router that supports both 10 Mbps and 100 Mbps.

Page 17

Hardware Installation and Network TopologyCHAPTER 1

NOTE

By default, flow control is enabled on all ports.

If you configure a port for full duplex, flow control is automatically disabled.

Excessive flow control problems

During times of peak network usage, you may occasionally see the FC/FD LED blink (for a description of the LED, see page 6). This is normal. However, if it stays lit for more than a few seconds at a time, or if there’s an excessive number of flow controls reported by the network management software, it could indicate a problem with your network configuration.

A port’s FC/FD LED indicator flashes whenever a packet is received that needs to be forwarded to a port that already has too many packets queued. This indicates a temporary overload situation on one port; the total traffic to the port exceeds the amount the buffer can hold. This typically occurs when there are several fast machines on different ports trying to access a machine across the switch. If this is infrequent, you don’t need to do anything. However, if this occurs often on the network, then the devices causing flow control to activate should be identified and moved to the same segment as the device that they are talking to.

When Ethernet bandwidth is temporarily insufficient for the traffic, there are only three possible actions: drop packets, use flow control, or segment the network. Buffering packets only works for a very short while. An extended overload will eventually overflow buffers and cause dropped packets. Flow control stops transmission on a port and forces devices to resend packets, ensuring that packets aren’t lost. This is the most reasonable solution, since it relies on Ethernet’s inherent collision detection mechanism to relieve temporary overload.

Repeater count limitations

The switch doesn’t count as a repeater. Each port on the switch can support a full Fast Ethernet network. There can be one repeater/hub between the switch and any workstations or servers (a stack of Intel Express 100BASE-TX Hubs counts as a single hub). Also, the total diameter of a segment can’t exceed 200 meters when using UTP cable. That is, the distance between any two nodes on a segment (or the switch and a node on the other side of a hub) can’t exceed 200 meters.

Page 18

Page 19

Configuring and

Managing the Switch

You don’t need to read this chapter unless you want to change the Express Switching Hub’s default configuration (see Appendix A for a list of defaults) or intend to manage the switch. The switch is ready to go simply by plugging it in and turning the power on.

However, if you need to change the default configuration or manage the switch, there are two ways:

• Use SNMP-compliant management software (not included). However, you must first use the Console Manager to assign an IP address to the switch.

• Use the Express Switching Hub’s internal Console Manager.

Page 20

CHAPTER 2

PC-3442

Intel Express 100BASE-TX Switching Hub

Accessing the Console Manager

The Console Manager software is contained in the switch’s nonvolatile RAM (NVRAM); you don’t need to install any software. To access the Console Manager:

1 Use the null-modem cable (included with the switch) to connect a

workstation’s COM port to the Console Mgmt port on the switch.

Console Mgmt

2 Open a terminal emulation program (such as Windows Terminal). 3 Select the COM port and these communication parameters:

9600 baud, eight data bits, no parity, one stop bit

In Windows Terminal, choose Communications from the Setting menu.

4 Press E. The login prompt appears:

By default, no login name or password is assigned. The password you enter becomes active only after you reset the switch or turn off the power. If you want the password to take effect immediately, use the set-passwd command.

Accessing the Console Manager remotely

To access remotely through Telnet, you must first set the IP configuration of the switch using the set-ip-conf command (see page 32 for instructions). You can then use Telnet to reach the switch.

In a remote session, all commands work exactly as if a terminal were directly connected to the Console Mgmt port. Note that only one console session can be active at a time. After the first Telnet session is established, the switch refuses other Telnet connections until the current session is closed. To terminate an active Telnet session, press E three times from the serial interface.

CHAPTER 2

Configuring and Managing the Switch

Using the Console Manager

The Console Manager provides an out-of-band (not on the network) connection to the switch. Use the Console Manager to

• assign an IP configuration to the switch.

• configure the ports.

• monitor network performance.

• create VLANs.

Entering commands

To enter commands, type the command name followed by any parameters and press E. For example, typing sys-stat E at the command prompt displays basic system status information.

Items in angle brackets represent values. For example,

represents an IP address in dotted decimal notation (such as

123.1.1.7).

Items in { } and separated by | represent alternatives for an argument. For example,

get-comm {read|write|*}

means you can type one of the following

get-comm read get-comm write

get-comm *

If you enter a command incorrectly, a message indicates the type of error that occurred. For example, typing a nonexistent command gives the following message:

SYS_console> pin command <pin> not found

If the command exists but the number of parameters is incorrect, the following message is displayed:

SYS_console> ping too few arguments

Page 22

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

Commands sometimes have parameters that determine how they’re saved and when they’re implemented. Some are changed in

• the running database so that the new value is used immediately (the run option).

• the NVRAM so that the changes are saved and occur only in the next session (the nvram option).

• both the running and the NVRAM databases (the all option).

To get an explanation of a command’s parameters, add a question mark (?) after the command name:

SYS_console> set-lt-age ? set-lt-age sets the LT aging period [arg #0] database type - either {run|nvram|all}

[arg #1] aging time in seconds

The Console Manager provides a history of the last several commands. To obtain the last command in the command history, press ! or cP at the prompt.

To correct a command line, use the following special keys (see the

help-kbd command):

• ! or cP - for the previous command

• cW - to delete the previous word

• cU - to delete the entire line

When you type a command that results in more than one screen of text appearing, you can press Q to stop the process or any other key to continue to the next screen.

Finally, you can press T to see the list of commands that start with the text already typed. For example:

SYS_console> get-c T Commands matching <get-c>

---------------------------------------------------

get-comm show current read or/and write community get-con-matrix displays the VLAN connectivity matrix get-colls-cnt gets the collision distribution counters per port

CHAPTER 2

Configuring and Managing the Switch

Console Manager command groups

The Console Manager has several categories of commands:

• Console commands: help, banner, serial line setup, console

parameters setup.

• System commands: system status, reset commands, download

commands, and system debug commands.

• IP commands: IP address setup, parameter and information

display.

• SNMP agent commands: SNMP settings, management, and trap

options.

• Switching database commands: aging time management and

switching database entry management.

• Spanning tree commands: disabling or manually configuring the

spanning tree protocol.

• VLAN commands: management of security virtual LANs.

• Port configuration commands: duplex and other port settings.

• Switching statistics commands: traffic and packet counters.

NOTE

Setting a port to full duplex automatically disables flow control. Since collisions don’t happen on a full-duplex link, flow control isn’t needed.

The following sections explain some of the more commonly used commands for configuring ports and monitoring traffic statistics.

Configuring a port for full duplex

Commands used

set-port-dplex get-port-cfg

Configuring a port for full duplex allows the switch to send and receive packets simultaneously with the destination device. To establish a full-duplex link, both the switch and the destination device must be configured for full duplex.

Additionally, the link must be to a switch, workstation, or server. You cannot establish a full-duplex link to a device that broadcasts incoming packets to every port on the device. This excludes most shared hubs, repeaters, or concentrators.

Sets the duplex mode on the specified port. Displays the current port configurations.

Page 24

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

NOTE

You must have a point-topoint connection to establish a full-duplex connection (shared hubs/repeaters/ concentrators aren’t capable of full duplex). Additionally, both points of the connection must be configured for full duplex.

To configure a port for full duplex

1 Configure the adapter or switch port on the other end for full

duplex.

2 Set the Express Switching Hub port to full duplex. This example

sets port 3 to full duplex:

set-port-dplex 3 full

3 Check the FC/FD LED. It should be solid yellow, indicating full

duplex.

Configuring the SNMP agent for IP

Commands used

set-ip-conf ping

The switch can be monitored and controlled through any SNMPcompliant network management system (NMS). First, you must configure the SNMP agent by assigning an IP address.

To configure the SNMP agent

1 Set the IP configuration. Type the command:

set-ip-conf 192.1.1.64 255.255.255.0 192.1.1.255

If the switch doesn’t have an IP address, then the specified IP configuration is changed immediately and saved in NVRAM.

If the switch is already configured, the command changes only the NVRAM. To use the new parameters, reset the switch using the warm-reset command.

2 Test the installation. Type the command:

SYS_console> ping 192.1.1.1 2

This example tests connectivity from the switch to a workstation with an IP address of 192.1.1.1. For more information on the ping command, see page 33.

3 Download the MIB from Intel’s Customer Support World Wide

Web site (http://www-cs.intel.com). The file is compressed in the file SWCH1MIB.EXE.

4 Compile the MIB into your NMS. See your NMS documentation

for more information.

Sets IP address, netmask, and broadcast address. Contacts another IP device.

CHAPTER 2

Configuring and Managing the Switch

Monitoring traffic

Commands used

get-br-cnt

get-eth-cnt get-colls-cnt

get-rmon-cnt get-sdist-cnt

get-mgm-brcnt clr-cnt

Use monitoring commands to determine the traffic volume from specific ports or between ports. This allows you to determine the traffic patterns of your network and adjust your network topology for maximum efficiency.

Statistics are generated for the current session. Reset counters by using the clr-cnt command, resetting the switch, or cycling the power.

Displays the packet statistics for a port. For a complete description, see page 52.

Displays the Ethernet counters for a port. Displays the collision distribution counters for a

port. Displays the Ethernet RMON counters for a port. Displays the packet size distribution counters for a

port. Displays the statistics for the management port. Resets the Ethernet and bridging statistics.

In general, keep devices that primarily talk to each other on the same segment (remember, each port is a Fast Ethernet segment). For example, if a high volume of traffic is forwarded from port 4 to port 3, determine which devices are generating traffic and move them to the same segment. This often happens when users are accessing a server on a separate segment. A change may not be efficient, however, if users from several segments all access the same server frequently.

To check traffic on a port

1 Determine the port you want to check. 2 Type the command:

SYS_console> get-br-cnt 3 Ethernet Switching Counters for port 3 ==================================================== Frm Received OK : 1419681 Bytes Received : 842637991 Frm Filtered : 0

Page 26

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

Frm to all ports : 0 Frm multicast : 16017 Frm lost/fctrl : 0 Transmit OK : 1404387 Forward to port : FRAMES BYTES

---------------------------------------------------- 1 : 0 0 2 : 0 0 3 : 218103808 60 4 : 1419823 842711315 5 : 0 0 6 : 0 0 7 : 0 0

====================================================

In this example, a station on port 3 is accessing a server on port 4. To reduce the amount of traffic crossing the switch, the server should be connected to a hub on port 3 instead of a hub on port 4. This keeps traffic localized to the same Fast Ethernet segment.

Creating VLANs

Commands used

set-vbc-domain del-vbc-domain get-vbc-tbl set-sec-vlan del-sec-vlan get-svlan-tbl

Sets up a Virtual Broadcast Domain (VBD). Deletes a VBD. Displays the VBD table. Sets up a security VLAN. Deletes a security VLAN. Displays the security VLAN table.

There are two types of VLANs:

• Security VLANs (SVLANs). Ports in an SVLAN can exchange packets only with other ports in the same SVLAN.

• VBDs: Ports in a virtual broadcast domain can exchange packets only with other ports in the same VBD. However, they can see broadcast frames from other ports in the same VBD.

Use only one type. Configuring both types in the same switch can lead to unpredictable traffic patterns.

If you want a device to talk to multiple VLANs (for example, a management workstation), apply a custom filter to the device. See page 24 for instructions.

Page 27

CHAPTER 2

Configuring and Managing the Switch

To create an SVLAN

1 Determine the ports you want to group together. 2 Type the command:

set-sec-vlan all 3-4-5

This command groups port 3, 4, and 5 as an SVLAN immediately and saves the entry in NVRAM. Replace all with nvram to save the entry without changing it immediately or with run to change the entry now without saving it.

3 To display a summary of saved SVLANs, type

get-svlan-tbl nvram

Any SVLANs created with the nvram or all option are displayed.

To create a VBD

1 Determine the ports you want to group together. 2 Type the command:

set-vbc-domain run 3-5-6-7

This command groups port 3, 5, 6, and 7 as a VBD temporarily (only until the next reset or power down). To save the entry and have it take effect now, replace run with all.

3 To display a summary of saved VBDs, type

get-vbc-tbl nvram

Page 28

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

Configuring the spanning tree

Commands used

get-stp Displays the spanning tree session state. set-stp Enables or disables the spanning tree for the next

session.

get-st-bcfg Displays the spanning tree bridge parameters. get-st-pcfg Displays the spanning tree port parameters table. get-st-syscfg Displays the spanning tree system ports

configuration.

set-br-prio Sets the spanning tree bridge priority. set-br-maxage Sets the spanning tree bridge maximum age. set-br-hellot Sets the spanning tree bridge hello time. set-br-fwdel Sets the spanning tree bridge forward delay. set-prt-prio Sets the spanning tree port priority. set-prt-enb Enables or disables a port spanning tree. set-prt-pcost Sets the spanning tree port path cost.

Spanning tree is a protocol that determines which port is turned off in a redundant configuration. Spanning tree is enabled anytime a packet could potentially be caught in an infinite loop on the network (for example, when two switches are connected to each other and also to the same bridge). The protocol uses the port with the lowest-cost path and turns off the other port. If one path fails, the other path is automatically turned on.

Spanning tree is enabled by default. See the “Spanning tree commands” section later in this chapter for more information.

Creating custom filters

Commands used

add-cf-entry del-cf-entry get-lt-filter get-nv-cftbl

Adds a custom filter entry. Deletes a custom filter entry. Displays the filter for a given MAC address. Displays all configured custom filters.

Page 29

CHAPTER 2

NOTE

Source ports start with port 1. Destination ports start with port 0, which is the internal SNMP management port.

Configuring and Managing the Switch

Use custom filters to control where the switch forwards packets from a given MAC address. Custom filters override VLANs. This is useful when you want a device to talk to devices outside of its VLAN.

Filters are defined for a set of ports. For example, you can set a custom filter that tells the switch to forward packets received on ports 3 and 4 to ports 6 and 7.

To set a custom filter

1 Determine the MAC address of the device you’re applying the

filter to.

2 Determine the switch ports where the device’s packets will arrive.

These are the source ports.

3 Determine the switch ports where the device’s packets will be

forwarded. These are the destination ports.

4 Use the Custom Filter Port Tables in Appendix A to find the

source and destination port hexadecimal equivalents.

5 Type the command:

add-cf-entry perm 00-A0-C9-11-11-11 C C0

This custom filter would send packets from the device with MAC address 00-A0-00-11-11-11 arriving on ports 3 or 4 (hexadecimal C) to both ports 6 and 7 (hexadecimal C0).

Console Command Reference

The console commands configure the Console Manager parameters and interface.

The screen displays the following information:

• SNMP agent software version and release date.

• Device SNMP object ID

• Device MAC address.

• System uptime (in 1/100 of a second) and in days, hours, minutes, and seconds.

• Port description and status. Ports 1 and 2 appear as missing unless you have optional media adapters installed.

warm-reset

Resets the SNMP agent software without resetting the switch (it doesn’t disconnect existing connections). The switch configuration is loaded from the values saved in NVRAM. The statistics counters are also reset by this command.

cold-reset

Performs a cold reset, which is equivalent to turning the power off and on again. Existing connections are also lost.

init-nvram

Resets the NVRAM on the SNMP agent to default values. Changes don’t take effect until you use the warm-reset or cold-reset commands or cycle the power. Default values are listed in Appendix A.

set-line-slip

set-line-slip {9600|19200|38400}

Changes the console serial port to SLIP mode for out-of-band SNMP management. The argument to the command is the new baud rate for the interface. SLIP can be used with a terminal server but not with a modem. The SLIP interface can be configured using the

set-slip-conf console command. The serial port can be returned to

console mode by pressing E three consecutive times from a terminal.

set-sw-file

set-sw-file <

filename

Sets the name of the file downloaded by TFTP (trivial file transfer protocol). This command is used in case of an update to the switch’s firmware. The file name must match the name of the agent software file on a TFTP server. When TFTP is used, the per-packet retransmission time-out value on the server (not the switch) must be increased to 10 seconds, since the SNMP agent must first erase its flash EEPROM, which takes about 30 seconds.

Page 34

CHAPTER 2

CHAPTER 2

Configuring and Managing the Switch

IP Configuration

get-ip

Shows the switch’s current IP address:

SYS_console> get-ip The device IP address is: 129.001.001.064 SYS_console> _

If the switch doesn’t have an IP address assigned:

SYS_console> get-ip The device has no IP address defined.

get-ip-conf

Shows the complete current IP configuration: IP address, netmask (subnet mask), and broadcast address.

SYS_console> get-ip-conf The device has no IP Address defined SYS_console> get-ip-conf

The device IP address, netmask and broadcast are: IP address : 129.001.001.064 IP netmask : 255.255.000.000 IP broadcast : 129.001.001.000

NOTE

If the IP configuration is not specified, the agent will not respond to any in-band requests, including ping messages and network management applications.

set-ip

set-ip <

IPaddress>

Sets the IP address of the switch (technically, the switch’s SNMP agent). If no IP address was previously set (which is the default configuration), the new value is used immediately and saved in NVRAM. Otherwise, the new value is stored in NVRAM, but you must use the warm-reset command or cycle the power for changes to take effect.

Example:

set-ip 129.001.001.064 Device IP Address unchanged for this session

Device IP Address change in the NVRAM OK The device NVRAM IP address will be:

IP address : 129.001.001.064

Page 36

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

NOTE

If you change the class of the IP address, make sure you also change the netmask. If you don’t, the switch will ignore the IP address change. Check for the appropriate netmask when you change the IP address.

set-ip-conf

set-ip-conf <

IPaddress> <netmask

> <

broadcast

Sets IP address, netmask (subnet mask) and broadcast IP address. If no IP configuration was previously set (which is the default configuration), the new values are used immediately and saved in NVRAM. If a previous IP configuration was being used, the new configuration is saved in NVRAM for the next session. To use the new values immediately, use the warm-reset command or cycle the power.

SYS_console> set-ip-conf 129.1.1.64 255.255.0.0 129.1.1.0 Device IP Address set for this session

Device IP Address change in the NVRAM OK The device IP configuration in the next session will be: IP address : 129.001.001.064 IP netmask : 255.255.000.000 IP broadcast : 129.001.001.000

get-bootp

Displays the current state of the BOOTP process. By default, BOOTP is disabled.

set-bootp

set-bootp {enable|disable}

Enables or disables BOOTP. With BOOTP, the switch looks for a BOOTP server at startup if no IP configuration is defined.

get-slip

Displays the current SLIP address. By default, no SLIP address is assigned.

get-slip-conf

Displays the current SLIP configuration.

set-slip

set-slip <

IPaddress

Sets the SLIP address, which cannot be the same as the IP address.

get-gatew

Shows the default gateway. This is the default router to use when accessing a different IP network.

set-gatew

set-gatew <

IPaddress

Sets the default gateway IP address, which specifies the router used to access a different IP network. The default value for this setting is

0.0.0.0 (no gateway).

SYS_console> set-gatew 129.1.1.1 Device Default Gateway change in the NVRAM OK

Device Default Gateway changed to : 129.1.1.1 SYS_console> get-gatew Device default gateway address is: 129.001.001.001

get-def-ttl

Returns the default IP time to live (TTL) value. This value (from 1 to

255) is the number of routers a frame can go through before being dropped. The default is 10.

set-def-ttl

set-def-ttl <

number

Modifies the default TTL value, from 1 to 255 router hops allowed.

Ping commands

The ping command sends an Internet Control Message Protocol (ICMP) echo request packet to a station. The ping process is asynchronous, so any responses are mixed in with other system console messages. For this reason, it’s best to avoid typing other commands (except ping-stop, which cancels the ping) while the ping process is active.

line of output appears for every response received. Normal response time is 1 to 10 seconds.

The ping command is intended for testing the connectivity between the switch and an IP station. It is not intended as a traffic generator, so it’s best to avoid using an endless ping. To stop the ping, use cC or enter the ping-stop command.

SYS_console> ping 129.1.1.1 10

— press <CR> to get the prompt again

If the host doesn’t respond, the console prompt appears and no output is added. Failure to get an echo response from a host may be due to the following:

• A bad physical connection.

• A nonexistent or inactive host.

• network unreachable: no corresponding entry in the routing table.

• destination unreachable: the default gateway failed to route the

datagram.

• outdated Address Resolution Protocol (ARP) table information:

clear the ARP table with the del-arp-entry command.

If there’s an active ping process due to a previous “long” ping command and you try to start a new ping, the command fails.

ping-stop

Stops the active ping process. You can also use cC.

Address Resolution Protocol (ARP) Commands

get-arp-tbl

Shows the ARP table. This table shows the port and MAC address for each IP address in the table.

SYS_console> get-arp-tbl IfIndex IpAddress MAC Address ==================================================== 1 129.001.001.001 00-40-05-2D-73-9C 1 129.001.001.200 00-02-A0-D4-9A-57

add-arp-entry

add-arp-entry <

IPaddress

> <

mac_address

Adds an entry to the ARP table manually.

del-arp-entry

del-arp-entry {<

IPaddress

>|*}

Deletes entries from the ARP table. If you enter an IP address, the matching ARP entry is deleted. If you enter * , the entire ARP table is cleared. Use this command if the network topology has physically changed. For example, if a management station moves from one segment to another, its port number changes.

SNMP commands

This section lists commands for configuring the SNMP agent itself, access and trap configuration.

SNMP community strings

SNMP community strings authenticate access to the Management Information Base (MIB). Community strings function as “passwords” embedded in every SNMP packet. The community string must match one of the two community strings configured in the switch for the message to be processed. There are two community strings, one for each of the following type of access:

• read mode gives read access to all the objects in the MIB, but doesn’t allow write access.

• write mode gives read and write access to all objects in the MIB.

get-comm

get-comm {read|write|*}

Displays the SNMP community string for a given access mode (read or write). If the access mode is specified as *, both read and write community strings are displayed.

SYS_console> get-comm * Current read community is: < public >

Current write community is: < private >

Page 40

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

set-comm

set-comm {read|write} <

community-string

Specifies the SNMP community string for each of the two access modes (read and write).

SYS_console> set-comm write password New write community is: < password >

SNMP trap message commands

When the switch detects an irregular event, it generates a trap. A trap is a notification message that can be sent to predefined network management stations. A trap event can be a cold or warm reset, detection of a port link status change, an SNMP authentication failure due to an incorrect community string, or similar event.

The SNMP trap commands let you specify

• whether the Express Switching Hub issues an authentication trap.

• which NMSs (up to five) the SNMP agent sends traps to.

get-auth

Displays the authentication trap setting. By default, authentication trap messages are enabled.

set-auth

set-auth {on|off}

Changes the authentication trap setting. The default is on, meaning the switch generates authentication traps. Specifying off prevents the switch from sending authentication traps.

get-traps

Displays the list of traps receiving stations (their IP address and trap SNMP community string).

Switching database commands

This section contains instructions for managing the switching database with the Console Manager.

The switching database, also called a learn table or address table, consists of 1024 entries. Each active entry contains the information relevant to a network node, identified by its Ethernet MAC address. Each entry contains the following information:

Lock. If on (denoted as a +), the entry is a static entry and isn’t deleted by the switch aging process. If off (denoted as a -), the entry is a dynamic entry that’s automatically deleted if the workstation is not active during the aging time period.

Page 42

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

Self(not user configurable). If on (denoted as a +), the entry is a system address. These are the switch’s individual and group addresses, as well as other addresses added by the management system. If off (denoted as a -), the entry contains the MAC address of a station on the network.

Dport. The destination port where frames from the entry are forwarded. If the MAC address is a custom filter, this doesn’t apply.

Mgmt. If on (denoted as a +), frames from the entry are sent to the management port on the switch.

The first section, “Virtual addresses,” lists commands relevant to standard MAC addresses (for example, determining the behavior of the switch when it sees a particular address). The second section, “Custom filtering,” lists commands pertinent to the custom filtering capabilities of the switch.

This command sends packets from the device with MAC address 00-A0-C9-00-11-11 to port 3. lock-off means the entry is deleted if the device is inactive for 300 seconds (the default aging time).

get-lt-age

Displays the switching database aging time in seconds. This is the amount of time the switch stores a device’s MAC address before clearing it from the database. An entry whose MAC address doesn’t appear in the source field of an incoming packet for this period of time is discarded. The default is 300 seconds.

CHAPTER 2

Intel Express 100BASE-TX Switching Hub

Custom filtering

Custom filters are useful for ensuring that a device can reach other devices regardless of where the device is attached. For example, if you have a laptop computer that acts as a management station, you want to make sure you can reach your servers from any part of your network, even if some segments have security VLAN restrictions.

The custom filter entry for an address is shown onscreen as a matrix. The source (SRC) column lists the available source ports (1 through 7, where ports 1 and 2 may or may not be installed). The other columns each represent an available destination port. A + represents a forwarding path. In the example, each source port (except port 3, because ports don’t forward frames to themselves) forwards frames to port 3.

get-con-matrix

Displays the current connectivity matrix for the switch. The first column is the source port. The other columns are destinations where frames from a given source port can be forwarded. Unlearned addresses (addresses that aren’t in the switching database) are forwarded to all ports marked with a + in the source port’s row. Learned addresses are forwarded to their destinations only if the destination is marked with a + in the source port’s row. Ports don’t need to be forwarded to themselves.

Troubleshooting

If there is an operating problem with the Express Switching Hub, incorrect configuration or cabling is probably the cause. Try the troubleshooting steps below in order:

1 Verify that your cables are wired correctly. This is the most

common problem. Use a UTP crossover cable to directly connect another switch, server, or workstation to the switch. Use a straightthrough cables when connecting to a repeater. See page 8 for more information.

2 Make sure the unit is plugged into a grounded, functioning AC

outlet providing between 90 VAC and 264 VAC at 50/60 Hz.

3 Review the Link LEDs of other devices to ensure that those ports

you believe should be functioning are properly attached to the switch with a Category 5 UTP cable.

4 Review the switch’s Link LEDS to ensure that ports you believe

should be functioning are properly configured, and not disabled or partitioned.

5 If you configured a port for full duplex, make sure the device on

the other end is configured for full duplex and is capable of transmitting in full duplex. Remember, you must have a point-topoint connection for a full-duplex link. Most repeaters aren’t capable of full duplex.

Page 64

CHAPTER 3

Intel Express 100BASE-TX Switching Hub

6 If the FC/FD LED shows excessive activity, see Chapter 1 for

recommendations on dealing with excessive flow control.

7 Make sure that the equipment attached to the switch is properly

configured. If the CLSN LED is on continuously, you may have a problem with an adapter on the segment.

8 Use the Console Manager to check the switch’s status. Use the

sys-stat command to check the overall system status and the getport-cfg command to check the status of each port.

If you encounter any situations or problems you cannot solve, get the following information:

• The serial number of the Express Switching Hub printed on the

back side of the switch.

• The firmware revision number displayed in the Console Manager

sys-stat message.

• The configuration of the equipment connected to the switch.

• The sequence of events leading up to your problem.

• Actions you have already taken. If you call Intel Customer Support, you have 90 days of free support

after your first call. Thereafter, Intel offers several pay-for-support options.

Technical InformationAppendix A

SNMP and MIB Support

The Express Switching Hub contains a built-in SNMP agent running on the SNMP processor board. This allows each Express Switching Hub to be managed from a centralized management station via any SNMP-compliant NMS.

The SNMP agent software complies with the following standards:

• RFC 1155, The Structure of Management Information (SMI) for

TCP/IP Based Internets, 5/90.

• RFC 1556, Management Information Base (MIB) for Network

Managers of TCP/IP Based Internets, 5/90.

• RFC 1557, The Simple Network Management Protocol (SNMP), 5/

90.

• RFC 1213, The Management Information Base II (MIB II), 3/91.

• RFC 1643, Definitions of Managed Objects for the Ethernet-like

Interface Types.

• RFC 1573, Evolution of the Interfaces Group of MIB-II, 1/94.

• RFC 1493, Definitions of Managed Objects for Bridges, 7/93.

• RFC 793, Transmission Control Protocol.

• RFC 854, Telnet Protocol Specification.

• RFC 1055, Nonstandard for transmission of IP datagrams over

serial lines: SLIP, 1/88.

The SNMP agent uses UDP/IP (RFC 768, RFC 950, RFC 1071 and RFC 791) as OSI layers 3 and 4 protocols, and ICMP (RFC 792) and ARP (RFC 826) to complete the UDP/IP protocol suite.

The UDP/IP stack implementation is conformant to:

• RFC 1122, Requirements for Internet hosts, communication layers.

• RFC 1123, Requirements for Internet hosts, application and

support.

The Express Switching Hub may be managed by any SNMP Manager that conforms to the above standards.

The Express Switching Hub implements an Intel Enterprise MIB. Download SWCH1MIB.EXE from the Intel Customer Support World Wide Web site (http://www-cs.intel.com) or Intel’s FTP site (see inside back cover).
