Page 15: Switch Management
Connecting to the Switch Configuration Options The TigerSwitch 10/100 SMC6750L2 includes a built-in network management agent. The agent offers a variety of management options, including SNMP, RMON and a Web-based interface. A PC may also be connected directly to the switch for configuration and monitoring via a command line interface (CLI).
Page 16: Required Connections
Set broadcast storm control on any port • Display system information and statistics Required Connections The switch provides an RS-232 serial port that enables a connection to a PC or terminal for monitoring and configuring the switch. A null-modem console cable is provided with the switch.
Page 17 Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the switch. You can use the console cable provided with this package, or use a null-modem cable that complies with the wiring assignments shown in Appendix B.

Page 23: Enabling Snmp Management Access
The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as EliteView. You can configure the switch to (1) respond to SNMP requests or (2) generate SNMP traps. When SNMP management stations send requests to the switch (either to return information or to set a parameter), the switch provides the requested data or sets the specified parameter.
Page 24: Community Strings
Community strings are used to control management access to SNMP stations, as well as to authorize SNMP stations to receive trap messages from the switch. You therefore need to assign community strings to specified users or user groups, and set the access level.
Page 25: Saving Configuration Settings
“community-string” is the string associated with that host. Press <Enter>. 2. In order to configure the switch to send SNMP notifications, you must enter at least one snmp-server enable traps command. Type “snmp-server enable traps type,” where “type” is either authentication or link-up-down.
Page 26: Managing System Files
See “Upgrading Firmware via the Serial Port” on page A-2. Due to the size limit of the flash memory, the switch supports only two operation code files. However, you can have as many diagnostic code files and configuration files as available flash memory space allows.
Page 27: System Defaults
System Defaults The switch’s system defaults are provided in the configuration file “Factory_Default_Config.cfg.” To reset the switch defaults, this file should be set as the startup configuration file. See “Setting the Startup Configuration File” on page 2-19. The following table lists some of the basic system defaults.

ONFIGURING THE WITCH Setting Broadcast Storm Thresholds 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 complete halt.
Page 59: Configuring Port Mirroring
Configuring 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.
Page 60: Address Table Settings
Setting Static Addresses A static address can be assigned to a specific interface on this switch. Static addresses are bound to the assigned interface and will not be moved. When a static address is seen on another interface, the address will be ignored and will not be written to the address table.
Page 61: Displaying The Address Table

Page 73 VLAN-unaware device). VLAN Classification – When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns the frame to an associated VLAN (based on the PVID of the receiving port.
Page 74: Forwarding Tagged/Untagged Frames
Forwarding Tagged/Untagged Frames If you want to create a small port-based VLAN for devices attached directly to a single switch, you can assign ports to the same untagged VLAN. However, to participate in a VLAN group that crosses several switches, you need to create a VLAN for that group and enable tagging on all ports.

Page 81: Configuring Vlan Behavior For Interfaces
Acceptable Frame Type – Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. If only tagged frames are accepted, the switch will only accept frames if the frame tag matches a VLAN to which this interface has been assigned.
Page 82 • GVRP Status – Enables/disables GVRP for the interface. GVRP must be globally enabled for the switch before this setting can take effect. (See “Displaying Bridge Extension Capabilities” on page 2-20.) When disabled, any GVRP packets received on this port will be discarded and no GVRP registrations will be propagated from other ports.

Data packets in a port’s high-priority queue will be transmitted before those in the lower-priority queues. You can set the default priority for each interface, and configure the mapping of frame priority tags to the switch’s priority queues. LASS OF...
Page 84: Setting The Default Priority For Interfaces
WITCH Setting the Default Priority for Interfaces You can specify the default port priority for each interface on the switch. All untagged packets entering the switch are tagged with the specified default port priority, and then sorted into the appropriate priority queue at the output port.
Page 85: Mapping Cos Values To Egress Queues
Console(config-if)#switchport priority default 5 Mapping CoS Values to Egress Queues This switch processes Class of Service (CoS) priority tagged traffic by using four priority queues for each port, with service schedules based on Weighted Round Robin (WRR). Up to eight separate traffic priorities are defined in IEEE 802.1p.
Page 86 The priority levels recommended in the IEEE 802.1p standard for various network applications are shown in the following table. However, you can map the priority levels to the switch’s output queues in any way that benefits application traffic for your own network.
Page 87 Web – Click Priority/Traffic Classes. Assign priorities to the output queues, then click “Apply.” CLI – The following example shows how to map CoS values 0, 1 and 2 to CoS priority queue 0, value 3 to CoS priority queue 1, values 4 and 5 to CoS priority queue 2, and values 6 and 7 to CoS priority queue 3.
Page 88: Setting The Service Weight For Traffic Classes
WITCH Setting the Service Weight for Traffic Classes This switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each priority queue. As described in “Mapping CoS Values to Egress Queues” on page 2-55, the traffic classes are mapped to one of the four egress queues provided for each port.
Page 89: Mapping Layer 3/4 Priorities To Cos Values
Because different priority information may be contained in the traffic, this switch maps priority values to the output queues in the following manner: • The precedence for priority mapping is IP Port Priority, IP Precedence or DSCP Priority, and then Default Port Priority.
Page 90: Mapping Ip Precedence
ONFIGURING THE WITCH CLI – The following example globally enables IP Precedence service on the switch. Console(config)#map ip precedence Console# Mapping IP Precedence The Type of Service (ToS) octet in the IPv4 header includes three precedence bits defining eight different priority levels ranging from highest priority for network control packets to lowest priority for routine traffic.
Page 91 Precedence/DSCP Priority Status menu. CLI – The following example globally enables IP Precedence service on the switch, maps IP Precedence value 1 to CoS value 0 on port 5, and then displays all the IP Precedence settings for that port.
Page 92: Mapping Dscp Priority
ONFIGURING THE WITCH Mapping DSCP Priority The DSCP is six bits wide, allowing coding for up to 64 different forwarding behaviors. The DSCP replaces the ToS bits, and it retains backward compatibility with the three precedence bits so that non-DSCP compliant, ToS-enabled devices, will not conflict with the DSCP mapping.
Page 93 CLI – The following example globally enables DSCP Priority service on the switch, maps DSCP value 1 to CoS value 0 on port 5, and then displays all the DSCP Priority settings for that port. Console(config)#map ip dscp Console(config)#interface ethernet 1/5...
Page 94: Mapping Ip Port Priority
ONFIGURING THE WITCH Mapping IP Port Priority You can also map network applications to Class of Service values based on the IP port number (i.e., TCP/UDP port number) in the frame header. Some of the more common TCP service ports include: HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.
Page 95 CLI – The following example globally enables IP Port Priority service on the switch, maps HTTP traffic on port 5 to CoS value 0, and then displays all the IP Port Priority settings for that port. Console(config)#map ip port Console(config)#interface ethernet 1/5...
Page 96: Port Trunk Configuration
You can enable LACP on any port that is not already a member of a static trunk. If LACP is also enabled for the connected ports on another device, the switch and the other device will automatically create a trunked link. Besides balancing the load across each port in the trunk, the other ports provide redundancy by taking over the load if a port in the trunk fails.
Page 97: Dynamically Configuring A Trunk With Lacp
Dynamically Configuring a Trunk with LACP Web – Click Trunk/LACP Configuration. Select any of the switch ports from the scroll-down port list and click “Add.” After you have completed adding ports to the member list, click “Apply.” CLI – The following example enables LACP for ports 17 and 18.

Page 99: Configuring Snmp
Configuring SNMP 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.
Page 100: Specifying Trap Managers
Console(config)#snmp-server community spiderman rw Console(config)# Specifying Trap Managers You can specify up to five management stations that will receive authentication failure messages and other trap messages from the switch. Command Usage • You can enable or disable authentication messages via the Web interface.
Page 101: Multicast Configuration
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.
Page 102: Configuring Igmp Parameters
Configuring IGMP Parameters You can configure the switch to forward multicast traffic intelligently. Based on the IGMP query and report messages, the switch forwards traffic only to the ports that request multicast traffic. This prevents the switch from broadcasting the traffic to all ports and possibly disrupting network performance.
