Configuration Options

For advanced management capability, the TigerStack 100 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 management functions such as:

• Enable/disable any port

• Set the communication mode for any port

• Configure SNMP parameters

• Configure VLANs or multicast filtering

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

• Restart the system

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 2-17 for a complete description of configuration options.)

Note: If the default settings for the management agent’s serial port have

been modified and you are having difficulty making a console connection, you can display or modify the current settings using a Web browser as described under “Console Configuration” on page 3-5.

EQUIRED CONNECTIONS

In-Band Connections

Prior to accessing the Network Management Module 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.

After configuring the switch’s IP parameters, you can access the on-board configuration program from anywhere within the attached network. The on-board configuration program can be accessed using Telnet from any computer attached to the network. The switch and stack can also be managed by any computer using a Web browser (Internet Explorer 4.0, or Netscape Navigator 4.0 or above), or from a network computer using network management software such as EliteView.

Notes: 1. By default BOOTP is disabled. To enable BOOTP, see “IP

Configuration” on page 2-13.

2. Use the Network Configuration menu to specify the maximum number of simultaneous Telnet sessions that are supported by the system (up to four).

3. 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.

Assigning SNMP Parameters

Use the SNMP Configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP). The switch includes an on-board SNMP agent which monitors the status of its hardware, as well as the traffic passing through its ports. A computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the on-board agent are controlled by community strings. To communicate with the switch, the NMS must first submit a valid community string for authentication. The options for configuring community strings and related trap functions are described in the following sections.

Note: MT-RJ ports operate at 100 Mbps and support full- and

half-duplex mode. 100BASE-FX module ports operate at 100 Mbps, full-duplex only. 1000BASE-SX and 1000BASE-LX ports are fixed at 1000 Mbps, but auto-negotiate duplex mode and flow control. 1000BASE-T ports auto-negotiate speed (1000/100/10 Mbps), duplex mode and flow control.

Flow Control Disabled Used to enable or disable flow control. Flow control

can eliminate frame loss by “blocking” traffic from end stations or segments connected directly to the switch when its buffers fill. IEEE 802.3x flow control is used for full duplex. Note that flow control should not be used if a port is connected to a hub.

Speed and Duplex

100_FULL Used to set the current port speed and duplex mode.

The MT-RJ ports have a default setting of 100_FULL. Auto-negotiation is the default setting for 1000BASE-T, 1000BASE-SX and 1000BASE-LX; but is not available for 100BASE-FX.

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

Max (Message) Age

20 The maximum time (in seconds) a device can wait

without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to the network.

The minimum value is the higher of 6 or [2 x (Hello Time + 1)].

The maximum value is the lower of 40 or [2 x (Forward Delay - 1)].

Forward Delay 15 The maximum time (in seconds) the root device will

wait before changing states (i.e., listening to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result.

The maximum value is 30.

Priority 128 Defines the priority for the use of a port in the STA

algorithm. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e., lowest value) will be configured as an active link in the Spanning Tree. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled. The range is 0 - 255.

Page 56

Note: Fast Forwarding enables end-node workstations and servers to

overcome time-out problems when the Spanning Tree Algorithm is implemented in a network. Therefore, Fast Forwarding should only be enabled for ports connected to an end-node device.

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

determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. (Path cost takes precedence over port priority.)

The default and recommended range is: Ethernet: 100 (50~600) Fast Ethernet: 19 (10~60) Gigabit Ethernet: 4 (3~10) The full range is 1 - 65535.

Status

Displays current state of this port within the Spanning Tree:

No Link No link has been established on this port.

Disabled Port has been disabled by the user or has failed

diagnostics.

Blocking Port receives STA configuration messages, but

does not forward packets.

Listening Port will leave blocking state due to topology

change, starts transmitting configuration messages, but does not yet forward packets.

Learning Port has transmitted configuration messages for

an interval set by the Forward Delay parameter without receiving contradictory information. Port address table is cleared, and the port begins learning addresses.

Forwarding The port forwards packets, and continues

learning addresses.

The rules defining port status are:

• A port on a network segment with no other STA compliant bridging device is always forwarding.

• If two ports of a switch are connected to the same segment and there is no other STA device attached to this segment, the port with the smaller ID forwards packets and the other is blocked.

• All ports are blocked when the switch is booted, then some of them change state to listening, to learning, and then to forwarding.

Configuring Port Trunks

Port trunks can be used to increase the bandwidth of a network connection or to ensure fault recovery. You can configure up five trunk connections (combining 2~4 ports into a fat pipe) between any two standalone SMC6924MT switches, or up to 12 for an entire stack. However, before making any physical connections between devices, use the Trunk Configuration menu to specify the trunk on the devices at both ends. When using a port trunk, note that:

• The ports used in a trunk must all be of the same media type (MT-RJ, 100 Mbps fiber, 1000 Mbps fiber, or 10/100/1000 Mbps RJ-45). The ports that can be assigned to the same trunk have certain other restrictions as described on page 2-47.

• Ports can only be assigned to one trunk.

• The ports at both ends of a connection must be configured as trunk ports.

• The ports at both ends of a trunk must be configured in an identical manner, including speed, duplex mode, and VLAN assignments.

• None of the ports in a trunk can be configured as a mirror source port or mirror target port.

• All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from a VLAN.

• The Spanning Tree Algorithm will treat all the ports in a trunk as a whole.

• Enable the trunk prior to connecting any cable between the switches to avoid creating a loop.

• Disconnect all trunk port cables or disable the trunk ports before removing a port trunk to avoid creating a loop.

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 Protocol” on page 4-7.)

Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the switch to any of up to 256 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, you can organize any group of network nodes into separate broadcast domains, confining broadcast traffic to the originating group. This also provides a more secure and cleaner network environment. For more information on how to use VLANs, see “Virtual LANs” on page 4-3. The VLAN configuration screens are described in the following sections.

802.1Q VLAN Current Table Information

This screen shows the current port members of each VLAN and whether or not the port supports VLAN tagging. Ports assigned to a large VLAN group that crosses several switches should use VLAN tagging. However, if you just want to create a small port-based VLAN for one or two switches, you can assign ports to the same untagged VLAN. The current

configuration is shown in the following screen.

MAX Supported VLANs Maximum number of VLANs that can be configured

on this switch.

Current Number of VLANs Configured

The number of VLANs currently configured on this switch.

802.1Q VLAN Static Table Configuration

Use this screen to create a new VLAN or modify the settings for an existing VLAN. You can add/delete port members for a VLAN from any unit in the stack as a tagged or untagged member. Or you can prevent a port from being automatically added to a VLAN by the GVRP protocol.

The switch supports an overlapping VLAN feature that allows any port to be configured as a member of multiple VLANs. This enables inter-switch links to carry traffic from VLANs that cross the network. Also, shared resources, such as servers, can be connected to a port that is configured as a tagged member of multiple VLANs.

Note: Overlapping VLANs on a port connected to another device

requires that device, switch or server, including network card and operating system, to be VLAN tag aware.

Web-Based Configuration and Monitoring

As well as the menu-driven system configuration program, the agent module 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 functions with access to the switch’s MIB and RMON database.

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 protocol.

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.

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

If this is your first time to access the management agent, you should define a new Administrator password, record it and put it in a safe place. From the Main Menu, select Security and enter a new password for the Administrator. Note that passwords can consist of up to 11 alphanumeric characters and are not case sensitive.

Note: Based on the default configuration, a user is allowed three attempts

to enter the correct password; on the third failed attempt the current connection is terminated. See “Console Login Configuration” on page 2-22.
