S S W W I I T T C C H H M M A A N N A A G G E E M M E E N N T T 1.Connecting to the Switch Configuration Options The FMG-24K PLANEX COMMUNICATIONS INC 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 6 The switch’s CLI configuration program, Web interface, and SNMP agent allow you to perform the following management functions: > Set user names and passwords for up to 16 users > Set an IP interface for a management VLAN > Configure SNMP parameters >...
Page 7 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. Attach a VT100-compatible terminal, or a PC running a terminal emulation pro- gram to the switch.
Page 8 Remote Connections Prior to accessing the switch’s onboard agent via a network connection,you must first configure it with a valid IP address, subnet mask, and default gateway using a console connection, DHCP or BOOTP protocol. The IP address for this switch is assigned via 192.168.0.1 by default. To manual- ly configure this address or enable dynamic address assignment via DHCP or BOOTP, see “Setting an IP Address”...
Page 9: Basic Configuration
2.Basic Configuration Console Connection The CLI program provides two different command levels — normal access level (Normal Exec) and privileged access level (Privileged Exec).The commands available at the Normal Exec level are a limited subset of those available at the Privileged Exec level and allow you to only display information and use basic util- ities.
Page 10 1. Open the console interface with the default user name and password “admin” to access the Privileged Exec level. 2. Type “configure” and press <Enter>. 3. Type “username guest password 0 password,” for the Normal Exec level, where password is your new password. Press <Enter>. 4.
Page 11 > Manual Configuration — You can manually assign an IP address to the switch. You may also need to specify a default gateway that resides between this device and management stations that exist on another network segment. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods.
Page 12 Dynamic Configuration If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp restart” command to start broadcasting service requests. Requests will be sent periodically in an effort to obtain IP configuration information.

Page 15 Saving Configuration Settings Configuration commands only modify the running configuration file and are not saved when the switch is rebooted. To save all your configuration changes in nonvolatile storage, you must copy the running configuration file to the start-up configuration file using the “copy” command. To save the current configuration settings, enter the following command: 1.
Page 16: Managing System Files
3.Managing System Files The switch’s flash memory supports three types of system files that can be man- aged by the CLI program, Web interface, or SNMP. The switch’s file system allows files to be uploaded and downloaded, copied, deleted, and set as a start- up file.
Page 17: System Defaults
4.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 2-18). The following table lists some of the basic system defaults. Function Parameter Default...

Page 20: Configuring The Switch
CONFIGURING THE SWITCH 1.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).
Page 21 3. After you enter a user name and password, you will have access to the sys- tem configuration program. 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 to improve the switch’s response time to management commands issued through the Web interface (see “Managing STA Interface Settings”...
Page 22: Navigating The Web Browser Interface
2.Navigating the Web Browser Interface To access the Web-browser interface you must first enter a user name and pass- word. The administrator has Read/Write access to all configuration parameters and statistics. The default user name and password for the administrator is “admin.”...
Page 23 If this is your first time to access the management agent, you should define a new Administrator user name and password, record them and put them in a safe place. Select Security from the Main Menu, and then enter a new user name and password for the Administrator.

Page 47 > Trunk – Indicates if a port is a member of a trunk. To create trunks and select port members, see “Port Trunk Configuration” on page 2-61. Autonegotiation must be disabled before you can configure or force the interface to use the Speed/Duplex Mode or Flow Control options.
Page 48 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 49 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 50: Address Table Settings
9.Address Table Settings Switches store the addresses for all known devices. This information is used to route traffic directly between the inbound and outbound ports. All the addresses learned by monitoring traffic are stored in the dynamic address table. You can also manually configure static addresses that are bound to a specific port.
Page 51 CLI – This example adds an address to the static address table, but sets it to be deleted when the switch is reset. Console(config)#bridge 1 address 00-e0-29-94-34-de vlan 1 forward ethernet 1/1 delete-on-reset 3-79 Console(config)# Displaying the Address Table The Dynamic Address Table contains the MAC addresses learned by monitoring the source address for traffic entering the switch.
Page 52 CLI – This example also displays the address table entries for port 11. Console#show bridge 1 ethernet 1/11 3-80 Interface Mac Address Vlan Type --------- ----------------- ---- ----------------- Eth 1/11 00-10-b5-62-03-74 1 Learned Console# Changing the Aging Time You can set the aging time for entries in the dynamic address table. Command Usage The range for the aging time is 17 - 2184 seconds.
Page 53: Spanning Tree Protocol Configuration
10.Spanning Tree Protocol Configuration 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.
Page 54 > Spanning Tree State – Enable/disabled this switch to participate in a STA- compliant network. > 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.
Page 55 Displaying the current global settings for STA Web – Click STA/STA Information. CLI – This command displays global STA settings, followed by the settings for each port. Console#show bridge group 1 3-90 Bridge-group information -------------------------------------------------------------- Spanning tree protocol :ieee8021d Spanning tree enable/disable :enable Priority :32768...
Page 56 The current root port and current root cost display as zero when this device is not con- nected to the network. Configuring the global settings for STA Web – Click STA/STA Configuration. Modify the required attributes, click “Apply.” CLI – This example enables Spanning Tree Protocol, and then sets the indicated attributes.
Page 57 Managing STA Interface Settings You can configure STA attributes for specific interfaces, including port priority, path cost, and fast forwarding. You may use a different priority or path cost for ports of same media type to indicate the preferred path. Command Attributes The following global attributes are read-only and cannot be changed: >...
Page 58 The following interface attributes can be configured: > 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 pri- ority (i.e., lowest value) will be configured as an active link in the Spanning Tree.
Page 59 Web – Click STA/STA Port Information or STA Trunk Information. CLI – This example shows the STA attributes for port 5.

Page 62: Vlan Configuration
11.VLAN Configuration 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.
Page 63 Assigning Ports to VLANs Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port (that is, a port attached to a VLAN-aware device) if you want it to carry traffic for one or more VLANs and if the device at the other end of the link also supports VLANs.
Page 64 Automatic VLAN Registration – GVRP (GARP VLAN Registration Protocol) defines a system whereby the switch can automatically learn the VLANs to which each endstation should be assigned. If an endstation (or its network adapter) supports the IEEE 802.1Q VLAN protocol, it can be configured to broadcast a message to your network indicating the VLAN groups it wants to join.
Page 65: Displaying Basic Vlan Information

Page 70 Adding Interfaces Based on Static Membership Command Attributes > Interface – Port or trunk identifier. > Member – VLANs for which the selected interface is a tagged member. > Non-Member – VLANs for which the selected interface is not a tagged mem- ber.
Page 71 Configuring VLAN Behavior for Interfaces You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP timers. Command Usage > GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in order to automatically register VLAN members on interfaces across the network.
Page 72 > GARP Leave Timer – The interval a port waits before leaving a VLAN group. This time should be set to more than twice the join time. This ensures that after a Leave or LeaveAll message has been issued, the applicants can rejoin before the port actually leaves the group.
Page 73 Web – Click VLAN/VLAN Port Configuration or VLAN Trunk Configuration. Fill in the required settings for each interface, click “Apply.” CLI – This example sets port 1 to accept only tagged frames, assigns PVID 3 as the native VLAN ID, enables GVRP, sets the GARP timers, and then sets the switchport mode to hybrid.
Page 74: Class Of Service Configuration
12.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 four priority queues for each port. Data packets in a port’s high-priority queue will be transmitted before those in the lower-priority queues.
Page 75 Web – Click Priority/Default Port Priority or Default Trunk Priority. Modify the default priority for any interface, then click “Apply.” CLI – This example assigns a default priority or 5 to port 3. Console(config)#interface ethernet 1/3 3-68 Console(config-if)#switchport priority default 5 3-118...
Page 76 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 8 separate traffic priorities are defined in IEEE 802.1p. The default priority levels are assigned according to recommendations in the IEEE 802.1p standard as shown in the following table.
Page 77 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 78 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 2-53, the traffic classes are mapped to one of the four egress queues provided for each port.
Page 79 CLI – The following example shows how to assign WRR weights of 1, 4, 16 and 64 to the CoS priority queues 0, 1, 2 and 3. Console(config)#queue bandwidth 1 4 16 64 3-119 Console(config)#exit Console#show queue bandwidth 3-122 Queue ID Weight -------- ------ Console#...
Page 80 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. The default IP Precedence values are mapped one-to-one to Class of Service values (i.e., Precedence value 0 maps to CoS value 0, and so forth).
Page 81 Web – Click Priority/IP Precedence Priority. Select “IP Precedence” from the IP Precedence/DSCP Priority Status menu. Select an IP Precedence value from the IP Precedence Priority Table by clicking on it with your cursor, enter a value in the Class of Service Value field, and then click “Ap pl y. ” CLI –...
Page 82 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 compatibili- ty with the three precedence bits so that non-DSCP compliant, ToS-enabled devices, will not conflict with the DSCP mapping.
Page 83 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. (Note that the setting is global and applies to all ports on the switch.) Console(config)#map ip dscp 3-125...
Page 84: Port Trunk Configuration
13.Port Trunk Configuration Ports can be combined into an aggregate link to increase the bandwidth of a net- work connection where bottlenecks exist or to ensure fault recovery. You can create up to six trunks at a time, with any single trunk containing up to four ports. The switch supports both static trunking and dynamic LACP (Link Aggregation Control Protocol).
Page 85 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 89: Configuring Snmp
14.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. Access rights to the onboard agent are controlled by community strings.
Page 90 Web – Click SNMP/SNMP Configuration. Enter a new string in the Community String box and select the access rights from the Access Mode drop-down list, then click “Add.” CLI – The following example adds the string “spiderman” with read/write access.

Page 92: Multicast Configuration
15.Multicast Configuration 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 that want to receive the multicast register with their local multicast switch/router.
Page 93 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. Command Usage >...
Page 94 Command Attributes > IGMP Status — When enabled, the switch will monitor network traffic to deter- mine which hosts want to receive multicast traffic. This is also referred to as IGMP Snooping.

Page 96: Interfaces Attached To A Multicast Router
Interfaces Attached to a Multicast Router Multicast routers use the information obtained from IGMP Query, along with a multicast routing protocol such as DVMRP, to support IP multicasting across the Internet. These routers may be dynamically discovered by the switch or statically assigned to an interface on the switch.

Page 98 Displaying Port Members of Multicast Services You can display the port members associated with a specified VLAN and multi- cast IP address. Command Attribute > VLAN ID – Selects the VLAN in which to display port members. > Multicast IP Address – The IP address for a specific multicast service >...
Page 99 Adding Multicast Addresses to VLANs Multicast filtering can be dynamically configured using IGMP Snooping and IGMP Query messages as described in “Configuring IGMP Parameters” on page 2-68. For certain application that require tighter control, you may need to statical- ly configure a multicast service on the switch. First add all the ports attached to participating hosts to a common VLAN, and then assign the multicast service to that VLAN group.
Page 100 CLI – This example assigns a multicast address to VLAN 1, and then displays all the known multicast services supported on VLAN 1. Console(config)#ip igmp snooping vlan 1 static 224.0.0.12 ethernet 1/12 3-109 Console(config)#exit Console#show bridge 1 multicast vlan 1 3-111 VLAN M'cast IP addr.

Page 106: Entering Commands
2.Entering Commands This section describes how to enter CLI commands. Keywords and Arguments A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command “show interfaces status ethernet 1/5,” show interfaces and status are keywords, ethernet is an argument that specifies the interface type, and 1/5 specifies the unit/port.
Page 107 Getting Help on Commands You can display a brief description of the help system by entering the help com- mand. You can also display command syntax by using the “?” character to list keywords or parameters. Showing Commands If you enter a “?” at the command prompt, the system will display the first level of keywords for the current command class (Normal Exec or Privileged Exec) or configuration class (Global, Interface, Line, or VLAN Database).
Page 108 The command “show interfaces ?” will display the following information: Console>show interfaces ? counters Information of interfaces counters status Information of interfaces status switchport Information of interfaces switchport Partial Keyword Lookup If you terminate a partial keyword with a question mark, alternatives that match the initial letters are provided.
Page 109 Understanding Command Modes The command set is divided into Exec and Configuration classes. Exec com- mands generally display information on system status or clear statistical coun- ters. Configuration commands, on the other hand, modify interface parameters or enable certain switching functions. These classes are further divided into differ- ent modes.
