Configuration Options

For advanced management capability, the TigerSwitch 1000 management agent provides a menu-driven system configuration program. This program can be accessed by a direct or modem connection to the serial port on the rear panel (out-of-band), or by a Telnet connection over the network (in-band).

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

The management agent also includes an embedded HTTP Web agent. This Web agent can be accessed using a standard Web browser from any computer attached to the network.

The system configuration program and the SNMP agent support managem ent func tio ns such as:

• Enable/disable any port

• Set the communication mode for any port

• Configure SNMP parameters

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

• Restart the system

WITCH MANAGEMENT

Required Connections

Console Port (Out-of-Band) Connections

Attach a VT100 compatible terminal or a PC running a terminal emulation program to the serial port on the switch’s rear panel. Use the null-modem cable provided with this package, or use a null modem connection that complies with the wiring assignments shown in Appendix B of this guide.

When attaching to a PC, set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, and 19200 bps (for initial configuration). Also be sure to set flow control to “none.” (Refer to “Configuring the Serial Port” on page 2-14 for a complete description of configuration options.)

Remote Management via the Console Port

Configure the Switch Site

Connect the switch’s DB9 serial port to the modem’s serial port using standard cabling. For most modems which use a 25-pin port, you will have to provide an RS232 cable with a 9-pin connector on one en d an d a 25- pin co nnector on the other end. Set th e mo dem at the switch’s site to force auto-answer mode. The following is a sample initialization string: “ATQ1S0=1&D0&K0&W” as defin ed belo w:

Q1 : Inhibit result codes to DTE S0=1 : Auto answer on first ring D0 : Don’t care DTR K0 : Disables DTE/DCE flow control W : Write command to modem memory

WITCH MANAGEMENT

1-3

Configure the Remote Site

At the remote site, connect the PC’s COM port (COM 1~4) to the modem’s serial port. Set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, 19200 bps and no flow control.

In-Band Connections

Prior to accessing the management agent via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using an out-of-band connection or the BOOTP protocol.

Note: By default BOOTP is disabled. To enable BOOTP, see “IP

Configuration” on page 2-11.

Telnet Connection

Prior to accessing the management agent via an in-band Telnet connection, you must first configure it with a valid IP address, subnet mask, and default gateway using an out-of-band connection or BOOTP protocol. After configuring the switch’s IP parameters, you can access the on-board configuration program from anywhere within the attached network.

Note: Use the Network Configuration menu to specify the

maximum number of simultaneous Telnet sessions that are supported by the system (up to four).

WITCH MANAGEMENT

1-4

In-Band Network Connection

The on-board configuration program can be accessed using Telnet from any computer attached to the network. The switch can also be managed by any computer using a Web browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above), or from a network computer using network management software such as EliteView.

Note: The on-board 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 SMC’s free EliteView software.

Using the Spanning Tree Algorithm

The Spanning Tree Algorithm can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network. For a more detailed description of how to use this algorithm, refer to “Spanning Tree Algorithm” in Chapter 4.

Using a Mirror Port for Analysis

You c an mirr or traffic fr om any source por t to a target port for real-time analysis. You can then attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner. When mirroring port traffic, note that the target port must be included in the same VLAN as the source port. (See “C on fig ur in g Virtual LANs” on page 2-45.)

You can use the Mirror Port Configuration screen to designate a single Gigabit port pair for mirroring as shown below.

IGMP Multicast Filtering

Multicasting is used to support real-time applications such as video conferencing or streaming audio. A multicast server does not have to establish a separate connection with each client. It merely broadcasts its service to the network, and any hosts which want to receive the multicast register with their local multicast switch/ router. Although this approach reduces the network overhead required by a multicast server, the broadcast traffic must be carefully pruned at every multicast switch/router it passes through to ensure that traffic is only passed on the hosts which subscribed to this service.

This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts who want to receive a specific multicast service. The switch looks up the IP Multicast Group used for this service and adds any port which received a similar request to that group. It then propagates the service request on to any neighboring multicast switch/router to ensure that it will continue to receive the multicast service. (For more information, see “IGMP Snooping and IP Multicast Filtering” on page 4-6.)

Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the switch to any of up to 16 LAN groups. In conventional networks with routers, broadcast traffic is split up into separate domains. Switches do not inherently support broadcast domains. This can lead to broadcast storms in large networks that handle traffic such as IPX or NetBeui. By using IEEE 802.1Q compliant VLANs, yo u ca n or gani ze any group of netw or k n odes in to separate broadcast domains, confining broadcast traffic to the originating group. This also provides a more secure and cleaner netwo rk envi ro nm ent. For mo re in for ma tio n on h ow to use VLANs, see “Vi rtual LANs” on page 4-3.

Web-Based Configuration and Monitoring

As well as the menu-driven system configuration program, the switch provides an embedded HTTP Web agent. This agent can be accessed by any computer on the network using a standard Web browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above).

Using the Web browser management interface you can configure a switch and view statistics to monitor network activity. The Web interface also provides access to a range of SNMP management func tio ns wi th i ts MIB and RMON br owser utilities.

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

1. Configure it with a valid IP address, subnet mask, and default gateway using an out-of-band serial connection or BOOTP pro toc ol.

2. Set the Administrator user name and password using an out-of-band serial connection. Access to the Web agent is controlled by the same Administrator user name and password as the on-board configuration program.

Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled. The range is 0 - 255.

(Path) Cost 100/19/4 This parameter is used by the STA algorithm to

The Fast STA Mode enables end-node workstations and servers to overcome time-out problems when the Spanning Tree Algorithm is implemented in a network. Therefore, the Fast STA Mode should only be enabled for ports that are connected to an end-node device.
