Configuration Options

For advanced management capability, the on-board management agent provides a menu-driven system configuration program. This program can be accessed by a direct 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

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 2-16 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 “Configuring the Serial Port” on page 3-6.

In-Band Connections

Prior to accessing the switch’s on-board 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.

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 can also be managed by any computer using a Web browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0

EQUIRED CONNECTIONS

or above), or from a network computer using network management software such as

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

“IP Configuration” on page 2-12.

2. Up to four simultaneous Telnet sessions are supported by this switch.

3. The on-board program only provides access to basic configuration functions. To access the full range of SNMP management functions, you must use SNMPbased network management software, such as SMC’s free EliteView software.

Configuring Port Trunks

Ports can be combined into an aggregate link to increase the bandwidth of a network connection or to ensure fault recovery. You can configure trunks between any two SMC6724L2 or SMC6724L3 switches. Ports 1-24 on this switch can be grouped into a trunk consisting of two, four or eight ports, creating an aggregate bandwidth up to 400, 800 or 1600 Mbps when operating at full duplex. Ports 25-26 (extender module ports) can be trunked together creating an aggregate bandwidth up to 2 Gbps (see page 2-34). The ports that can be assigned to the same trunk are listed on page 2-33. Besides balancing the load across each port in the trunk, the additional ports provide redundancy by taking over the load if another port in the trunk fails. However, before making any physical connections between devices, use the Port Trunking Configuration menu to specify the trunk on the devices at both ends. When using a port trunk, remember that:

• 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 communication mode, and VLAN assignments.

• 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.

The Bridge menu is used to configure settings for the Spanning Tree Algorithm, as well as the global bridge settings for GMRP (GARP Multicast Registration Protocol) and GVRP (GARP VLAN Registration Protocol), traffic class priority threshold, and address aging time.

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, and provide backup links which automatically take over when a primary link goes down. For a more detailed description of how to use this algorithm, refer to “Spanning Tree Algorithm” on page 4-4.

EVICE CONTROL MENU

Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the switch to any of up to 256 Virtual 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, thus 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 4-5. The VLAN configuration screens are described in the following sections.

VLAN Port Configuration

You can use the VLAN Port Configuration screen to configure GARP, the default VLAN identifier, default port priority, VLAN tagging on outgoing frames, GVRP and GMRP status, and filtering of incoming frames for VLAN groups to which this port does not belong.

2. This switch supports Quality of Service (QoS) by using two priority

queues, with Weighted Fair Queuing for each port. Inbound frames that do not have VLAN tags are tagged with the input port’s default ingress user priority, and then placed in the appropriate priority queue at the output port. The default priority for all ingress ports is zero. Therefore, any inbound frames that do not have priority tags will be placed in the low priority queue of the output port. (Note that if the output port is an untagged member of the associated VLAN, these frames are stripped of all VLAN tags prior to transmission.)

Rx All: Accepts all frames, tagged or

Rx Tag: Only accepts tagged frames. The

switch will only accept frames if the PVID and frame tag are the same.

Tx All: If the PVID and frame tag are the

same, sends a tagged frame, otherwise sends an untagged frame.

Tx Untag: Sends only untagged frames.

3. If you want to create a small port-based VLAN for just one or two

switches, you can assign ports to the same untagged VLAN (and use a separate connection where a VLAN crosses the switches). However, to participate in a VLAN group that extends beyond this switch, we recommend using the VLAN ID for that group, by VLAN tagging. For Layer 2 switching, ports assigned to a large VLAN group that crosses several switches must use VLAN tagging.

Configuring IGMP Snooping

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 filtered at every multicast switch/router it passes through to ensure that traffic is only passed on to the hosts which subscribed to this service.

This switch uses IGMP (Internet Group Management Protocol) Snooping to monitor any attached hosts which want to receive a specific multicast service. It looks up the IP Multicast Group used for this service, and adds to it any port that received a similar request.

It may then be disabled as a security feature to ensure that frames from any station with an unknown MAC address are

Web-Based Configuration and Monitoring

In addition to the menu-driven system configuration program, this switch also 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 4.0 or above, or Netscape Navigator 4.0 or above).

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 a user name and password using an out-of-band serial connection (page 2-21). Access to the Web agent is controlled by the same user name and password as the onboard configuration program.

Note: 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 (see page 3-34) to improve the switch’s response time to management commands issued through the Web interface.

Assigning SNMP Parameters

Use the SNMP Configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP). The switch includes an onboard 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 agent module 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 figures and table.
