CHAPTER 1 INTRODUCTION This switch provides a broad range of features for Layer 2 switching. It includes a management agent that allows you to configure the features listed in this manual. The default configuration can be used for most of the features provided by this switch. However, there are many options that you should configure to maximize the switch’s performance for your particular network environment.
INTRODUCTION 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.
DESCRIPTION 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.
INTRODUCTION 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. System Defaults The following table lists some of the basic system defaults. Function Parameter Default IP Settings IP Address 0.0.0.0 Subnet Mask 0.0.0.
SYSTEM DEFAULTS Function Parameter Default Spanning Tree Protocol Status Enabled (Defaults: All values based on IEEE 802.

CHAPTER 3 CONFIGURING THE SWITCH 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.
CONFIGURING THE SWITCH Navigating the Web Browser Interface To access the Web-browser interface you must first enter a user name and password. The administrator has Read/Write access to all configuration parameters and statistics. The default user name and password for the administrator is “admin.” Home Page When your Web browser connects with the switch’s Web agent, the home page is displayed as shown below.
PANEL DISPLAY Configuration Options Configurable parameters have a dialog box or a drop-down list. Once a configuration change has been made on a page, be sure to click on the “Apply” button to confirm the new setting. The following table summarizes the Web page configuration buttons. Button Action Apply Sets specified values to the system for the displayed page. Default Cancels specified values and restores current values prior to pressing “Apply.
CONFIGURING THE SWITCH Main Menu Using the onboard Web agent, you can define system parameters, manage and control the switch, or monitor network conditions. The following table briefly describes the selections available from this program.
MAIN MENU Menu Description VLAN Configuration Basic Port VID Page 3-27 Configures VLAN groups, including name, identifier, and if limited to a specific protocol 3-28 3-29 Sets port VID and ingress filters 3-32 Spanning Tree Configures global bridge and port settings for STP; also displays current port status 3-34 Port Sniffer Sets the source and target ports for mirroring 3-39 SNMP 3-40 System Options Provides basic system description, including contact information 3-40 Community Strings
CONFIGURING THE SWITCH 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.
GLOBAL 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.
CONFIGURING 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.
CONSOLE PORT SETTINGS bound for low-priority packets if required, select the priority tags that will be processed by the high-priority queue, and then click Apply. Console Port Settings If you have access to the Web interface, but are having problems connecting to the console port, you can display the current connection parameters via the Console Information page, and adjust the settings for the PC or terminal connected to this port.
CONFIGURING THE SWITCH Port Configuration Displaying Connection Status Use the Port Status page to display the current connection status, including link state, auto-negotiation, speed/duplex mode, and flow control. Notes: 1. To set the port status, use the Port Control page as described under “Configuring Interface Connections” on page 3-11. 2. The “Config” field shows the configured settings, and the “Actual” field shows the current operational status.
PORT CONFIGURATION Configuring Interface Connections Use the Port Controls pages to enable/disable an interface, set auto-negotiation, or manually set the speed and duplex mode, and flow control parameters. Field Attributes • State – Allows you to manually disable an interface. You can disable an interface due to abnormal behavior (e.g., excessive collisions), and then reenable it after the problem has been resolved. You may also disable an interface for security reasons.
CONFIGURING THE SWITCH Showing Port Statistics You can display standard statistics on network traffic from the Interfaces Group MIB, Ethernet-like MIB, and RMOM MIB. These statistics display errors on the traffic passing through each port. This information can be used to identify potential problems with the switch (such as a faulty port or unusually heavy loading). All values displayed have been accumulated since the last system reboot, and are shown as counts per second.
TRUNK CONFIGURATION Web – Click Port Statistics. You can use the Reset button at the bottom of the page to update the screen. Trunk Configuration The switch supports both static trunking and dynamic Link Aggregation Control Protocol (LACP). You can create multiple links between devices that work as one virtual, aggregate link. A port trunk offers a dramatic increase in bandwidth for network segments where bottlenecks exist, as well as providing a fault-tolerant link between two devices.
CONFIGURING THE SWITCH • The ports at both ends of a trunk must be configured in an identical manner, including communication mode (i.e., speed, duplex mode and flow control), VLAN assignments, and CoS settings. • All the ports in a trunk have to be treated as a whole when moved from/ to, added or deleted from a VLAN. • The same STP, VLAN, and IGMP settings must be configured for all the ports in a trunk. Configuring Static Trunks You can manually assign specific ports to a static trunk.
TRUNK CONFIGURATION Web – Click Administrator=>Trunking=>Aggregator Setting. Select the group ID and click the Get button to display the settings for the specified group. Set LACP to “Disable.” Use the Add and Remove buttons to assign port members, and then click Apply. Click Administrator=>Trunking=>Aggregator Information to display currently configured static trunks and group members.
CONFIGURING THE SWITCH Configuring Dynamic Trunks Ports configured for LACP can automatically negotiate a trunked link with LACP-configured ports on another device. Command Usage • To avoid creating a loop in the network, be sure you enable LACP before connecting the ports; also disconnect the ports before disabling LACP.
TRUNK CONFIGURATION Aggregator Setting Field Attributes • System Priority – A value used to select the device that initiates an LACP trunk. The device with the lowest value has the highest priority and will be selected as the active LACP partner. • Group ID – Specifies the LACP trunk group. • LACP – Set this field to “Enable” when configuring a dynamic trunk. • Work Ports – Assigns port members to the dynamic trunk. (Range: 1-8) The number of active ports can also be specified in this field (i.
CONFIGURING THE SWITCH Aggregator Information Field Attributes Static Trunks • Group Key – Displays static trunks. • Port No – The port members assigned to the trunk. Dynamic Trunks • Actor – The device that initiated the trunk. • Partner – The device that responded to a link initialization request. • Priority – The priority used to select the device that initiates the trunk if both ends of the link are set to the LACP State of “Active.” This is the same as System Priority on the Aggregator Setting page.
TRUNK CONFIGURATION Web – Click Administrator=>Trunking=>Aggregator Information to display currently configured trunks and group members.
CONFIGURING THE SWITCH State Activity Set the port members to actively or passively initiate an LACP trunk. Field Attributes • Port – Lists all ports that can be configured as LACP trunk members. • LACP State Activity – When set to Active, a port can automatically initiate a trunk if an LACP partner is detected at the other end of the link. Web – Click Administrator=>Trunking=>State Activity. Specify the ports which can actively initiate an LACP trunk, and click Apply.
FORWARDING AND FILTERING Forwarding and Filtering This switch supports the following types of traffic filtering: • Multicast Filtering – This switch can forward multicast traffic to host devices that request to join a multicast service, and filter multicast traffic for all other ports which do not require multicast services. • Static MAC Address – Binds a physical address to a specific port and VLAN.
CONFIGURING THE SWITCH The purpose of multicast filtering is to optimize a switched network’s performance, so multicast packets will only be forwarded to those ports containing multicast group hosts or multicast routers/switches, instead of flooding traffic to all ports in the subnet. You can enable IGMP Snooping and Query via the Switch Settings menu, and display information about multicast traffic being forwarded by the switch via the Filtering Database menu as shown below.
FORWARDING AND FILTERING Click Administrator=>Filtering Database=>IGMP Snooping.
CONFIGURING THE SWITCH Setting Static Addresses A static address can be assigned to a specific interface on this switch. Traffic sent from devices listed in the static address table will only be accepted on the specified interface. If any packets with a source address listed in this table enter another interface, they will be dropped. When you add a static MAC address, it remains in the switch's address table, regardless of whether the device is physically connected to the switch.
FORWARDING AND FILTERING Configuring Port Security If you enable port security, the switch will stop learning new addresses on the specified port. Only incoming traffic with source addresses already stored in the dynamic address table will be accepted. The MAC addresses already in the address table will be retained and will not age out. This can be used to prevent unauthorized access to the switch.
CONFIGURING THE SWITCH Configuring Address Filtering You can drop traffic from unwanted stations based on the source MAC address (and associated VLAN if tagged VLANs are enabled). Field Attributes • MAC Address – Source MAC address. • Vlan ID – ID of configured VLAN (1-4094). This option is only available if IEEE 802.1Q tagged VLANs are enabled (page 3-29). Web – Click Administrator=>Filtering Database=>MAC Filtering. Enter a MAC address and associated VLAN, then click Apply.
VLAN CONFIGURATION VLAN Configuration Overview In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This also provides a more secure and cleaner network environment.
CONFIGURING THE SWITCH Port-based VLANs Port-based VLANs are typically used to reduce broadcast traffic and to increase security. A group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the switch. Packets are forwarded only between ports that are designated for the same VLAN. Port-based VLANs can be used to manually isolate user groups or subnets. However, you should use IEEE 802.
VLAN CONFIGURATION Tag-based VLANs An IEEE 802.1Q VLAN is a group of ports located anywhere in the network, but communicate as though they belong to the same physical segment by using frame tags to indicate VLAN membership. Tagged VLANs can help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections.
CONFIGURING THE SWITCH not overlap, but still need to communicate, you can connect them by using a Layer-3 router or switch. Protocol VLANs – This switch also supports VLANs based on specific protocol types, such as IPX and AppleTalk. When a protocol is bound to a VLAN, the switch will only forward packets carrying the specified protocol tag. However, regardless of the protocol type, remember that traffic must still be passed though a router to reach a different subnet.
VLAN CONFIGURATION Creating Tagged VLANs Web – Click Administrator=>Switch Settings=>Advanced. Set VLAN Operation Mode to 802.1Q with or without GVRP, then click Apply. Click Administrator=>VLAN Configuration=>Basic. Click Add to create a group. Enter the VLAN Name (1-15 characters) and Group ID (2-4094). Select a protocol type if you want to create a protocol based VLAN. Use the Add or Remove buttons to configure port members, then click Next.
CONFIGURING THE SWITCH Set each port to transmit tagged or untagged frames, then click Apply. Configuring the PVID and Ingress Filters You also need to configure the default port VLAN ID (PVID), ingress filtering, and acceptable frame types. Field Attributes • PVID – VLAN ID assigned to untagged frames received on the port.
VLAN CONFIGURATION Web – Click Administrator=>VLAN Configuration=>Port VID. Set the PVID and Ingress Filtering rules, then click Apply.
CONFIGURING THE SWITCH Spanning Tree Protocol Configuration The Spanning Tree Protocol (STP) detects and disables network loops and provides backup links between switches, bridges, and routers to ensure that only one route exists between any two stations on the network. The backup links automatically take over when a primary link goes down. Enabling STP To configure STP, first enable the protocol as shown below. Web – Click Administrator=>Switch Settings=>Advanced. Enable STP Protocol, and click Apply.
SPANNING TREE PROTOCOL CONFIGURATION 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. - Default: 20 - Minimum: The higher of 6 or [2 x (Hello Time + 1)] - Maximum: The lower of 40 or [2 x (Forward Delay - 1)] • Hello Time – Interval (in seconds) at which the root device transmits a configuration message.
CONFIGURING THE SWITCH Displaying Information About the Root Bridge The root bridge of the spanning tree is selected whenever the network is reconfigured. The root bridge is uniquely identified in the spanning tree by its priority and MAC address. The maximum age, hello time, and forward delay currently used by all bridges in the spanning tree are set to those values configured on the root bridge. (See the preceding page for a description of these parameters.
SPANNING TREE PROTOCOL CONFIGURATION Field Attributes • Priority – Defines the priority used for this port in the Spanning Tree Protocol. 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. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol is detecting network loops.
CONFIGURING THE SWITCH Displaying Port Status for STP You can display the current STP settings and state for each port. Field Attributes • Port State – Displays the current state of this port in the Spanning Tree: - Disabled - No link has been established on this port. Otherwise, the port has been disabled by the user or has failed diagnostics. - Blocking - Port receives STP configuration messages, but does not forward packets.
PORT MIRRORING Port Mirroring You can mirror traffic from any source port 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. Command Usage • Monitor port speed should match or exceed source port speed, otherwise traffic may be dropped from the monitor port. • All mirror sessions must share the same destination port.
CONFIGURING THE SWITCH Simple Network Management Protocol The switch includes an onboard agent that continuously monitors the status of its hardware, as well as the traffic passing through its ports, based on the Simple Network Management Protocol (SNMP). A network management station can access this information using software such as EliteView. Access rights to the onboard agent are controlled by community strings.
SIMPLE NETWORK MANAGEMENT PROTOCOL Field Attributes • Community String – A community string acts as a password and permits access to the SNMP protocol. • RO – Specifies read-only access. Authorized management stations are only able to retrieve MIB objects. • RW – Specifies read/write access. Authorized management stations are able to both retrieve and modify MIB objects. Web – Click Administrator=>SNMP. Enter a new string in the text box and select the access rights, then click Add.
CONFIGURING THE SWITCH User Authentication The administrator has write access for parameters governing the onboard agent. You should therefore assign a password as soon as possible, and store it in a safe place. (If your password is lost, reload the system firmware as described in Appendix B.) The default administrator name is “admin” with the password “admin.” Note that the user name and password controls access to both the Web interface and the console menu.
FIRMWARE AND CONFIGURATION SETTINGS Firmware and Configuration Settings Downloading System Software from a Server You can download firmware from a TFTP server. Field Attributes • TFTP Server IP Address – The IP address of a TFTP server. • Destination File Name – The file name should not contain slashes (\ or /), the leading letter of the file name should not be a period (.), and the maximum length for file names is 25 characters. (Valid characters: A-Z, a-z, 0-9, “.
CONFIGURING THE SWITCH Saving or Restoring Configuration Settings You can upload/download configuration settings to/from a TFTP server. The configuration file can be later downloaded to restore the switch’s settings. Field Attributes • TFTP Server IP Address – The IP address of a TFTP server. • Destination File Name – The configuration file name should not contain slashes (\ or /), the leading letter of the file name should not be a period (.), and the maximum length for file names is 15 characters.

SWITCH STATIC CONFIGURATION MENU Miscellaneous Configuration Menu Use the Misc Configuration menu to configure the features listed in the following table. TigerSwitch 10/100 : ===================== Misc Configuration Port Security MAC Age Interval Broadcast Storm Filtering Max bridge transmit delay bound Previous Menu Configurate the port security.
CONSOLE INTERFACE Configuring Port Security Use the Port Security page to lock the address table for specified ports. If you enable port security, the switch will stop learning new addresses on the specified port. Only incoming traffic with source addresses already stored in the dynamic address table will be accepted. The MAC addresses already in the address table will be retained and will not age out. This can be used to prevent unauthorized access to the switch.
SWITCH STATIC CONFIGURATION MENU Configuring Address Aging Use the MAC Age Interval page to set the address 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.
CONSOLE INTERFACE Configuring Broadcast Storm Control Use the Broadcast Storm Filtering page to set the broadcast threshold. 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.
SWITCH STATIC CONFIGURATION MENU Configuring the Transmit Delay Bound Use the “Max bridge transmit delay bound” page to set the maximum queuing delay. Field Attributes • Max bridge transmit delay bound – Limits the time packets can be queued in switch. If enabled, packets queued beyond the specified time will be dropped. (Range: OFF, 1, 2, 4 seconds; Default: OFF) • Enable Delay Bound – Enables a transmit delay for packets in the low-priority queue.
CONSOLE INTERFACE Protocol Related Configuration Menu Use the Protocol Related Configuration menu to configure the items listed in the following table. TigerSwitch 10/100 : ===================== Protocol Related Configuration STP SNMP GVRP LACP Previous Menu Configure the Spanning Tree Protocol.
PROTOCOL RELATED CONFIGURATION MENU Spanning Tree Protocol Menu Use the STP menu to configure the Spanning Tree Protocol. STP detects and disables network loops and provides backup links between switches, bridges, and routers to ensure that only one route exists between any two stations on the network. The backup links automatically take over when a primary link goes down.
CONSOLE INTERFACE Enabling STP To configure STP, first enable it using the STP Enable/Disable page. Console – Click Protocol Related Configuration=>STP=>STP Enable/ Disable. Enable the STP Protocol, and save your settings. TigerSwitch 10/100 : ===================== STP Enabled/Disabled Configuration STP :Enabled actions-> Select the action menu.
PROTOCOL RELATED CONFIGURATION MENU If there is no root port, then this switch has been accepted as the root device of the Spanning Tree network. • Maximum Age – 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.
CONSOLE INTERFACE Configuring Global STP Settings Use the System Configuration page to configure global settings for STP which apply to the entire switch. Field Attributes • Priority – Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device.
PROTOCOL RELATED CONFIGURATION MENU • Forward Delay Time – 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.
CONSOLE INTERFACE Configuring Port STP Settings Use the Perport Configuration page to set STA attributes for specific ports, including port priority and path cost. You can use a different priority or path cost for ports of the same media type to indicate the preferred path. Field Attributes • Priority – Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e.

CONSOLE INTERFACE Simple Network Management Protocol Menu Use the SNMP menu to configure basic information and management access settings for the Simple Network Management Protocol. The switch includes an onboard agent that continuously monitors the status of its hardware, as well as the traffic passing through its ports, based on the SNMP. A network management station can access this information using software such as EliteView. Access rights to the onboard agent are controlled by community strings.
PROTOCOL RELATED CONFIGURATION MENU Configuring System Information Use the System Options page to identify the system by providing a descriptive name, location, and contact information. Field Attributes • System Name – Name assigned to the switch system. • System Location – Specifies the system location. • System Contact – Administrator responsible for the system. Console – Click Protocol Related Configuration=>SNMP=>System Options.
CONSOLE INTERFACE Setting Community Access Strings You can use the Community Strings page to configure up to five community strings authorized for management access. For security reasons, you should consider removing the default strings. Field Attributes • Community Name – A community string acts as a password and permits access to the SNMP protocol. • Write Access - Restricted – Specifies read-only access. Authorized management stations are only able to retrieve MIB objects.
PROTOCOL RELATED CONFIGURATION MENU Specifying Trap Managers You can use the Trap Managers page to specify up to five management stations that will receive authentication failure messages and other trap messages from the switch. Field Attributes • IP – IP address of trap manager. • Community Name – A community string acts as a password and allows the trap manager to receive trap messages via the SNMP protocol. Console – Click Protocol Related Configuration=>SNMP=>Trap Managers.
CONSOLE INTERFACE GVRP Configuration GARP VLAN Registration Protocol (GVRP) defines a method for switches to exchange VLAN information in order to register VLAN members on ports across the network. VLANs are dynamically configured based on join messages issued by host devices and propagated throughout the network. Use the GVRP page to enable automatic VLAN registration, and to support VLANs which extend beyond the local switch.
PROTOCOL RELATED CONFIGURATION MENU Link Access Control Protocol Menu Use the LACP menu to configure dynamic trunking whereby the switch will automatically negotiate a trunked link with LACP-configured ports on another device. Command Usage • To avoid creating a loop in the network, be sure you enable LACP before connecting the ports; also disconnect the ports before disabling LACP.
CONSOLE INTERFACE Configuring the Aggregator Setting First use the Port Configuration page to create trunk groups (page 4-16), and then use the Aggregator Setting page to enable LACP and specify the maximum number of active ports. Field Attributes • Group – Specifies the LACP trunk group. • LACP – Set this field to “Enabled” when configuring a dynamic trunk. • LACP Work Port Num – Specifies the number of active ports.
PROTOCOL RELATED CONFIGURATION MENU Setting the State Activity Use the State Activity page to set the port members to actively or passively initiate an LACP trunk. Field Attributes • Port – Lists all ports that can be configured as LACP trunk members. • State Activity - Active – A port can automatically initiate a trunk if an LACP partner is detected at the other end of the link. - Passive – A port can only create a trunk if an LACP partner at the other end of the link sends a request to initiate the trunk.
