Connecting to the Switch

Configuration Options

The TigerAccess Extended Ethernet (EE) Switch 7724M/VSW 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).

Note: The IP address for the switch is assigned via DHCP by default. To

change this address, see “Setting an IP Address” on page 1-7.

The switch’s HTTP Web agent allows you to configure switch parameters, monitor port connections, and display statistics graphically using a standard Web browser such as Netscape Navigator version 6.2 and higher or Microsoft IE version 5.0 and higher. The switch’s Web management interface can be accessed from any computer attached to the network.

The switch’s management agent is based on SNMP (Simple Network Management Protocol.) This SNMP agent permits the switch to be managed from any system in the network using management software, such as SMC’s free EliteView software.

The CLI program can be accessed by a direct connection to the RS-232 serial console port on the switch, or remotely by a Telnet connection over the network.

The switch’s CLI configuration program, Web Interface, and SNMP agent allow you to perform the following management functions:

ONNECTING TO THE SWITCH

1-3

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 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 of this guide.

To connect a terminal to the console port, complete the following steps:

1. Connect the console cable to the serial port on a terminal, or a PC running terminal emulation software, and tighten the captive retaining screws on the DB-9 connector.

2. Connect the other end of the cable to the RS-232 serial port on the switch.

3. Make sure the terminal emulation software is set as follows:

• Select the appropriate serial port (COM port 1 or COM port 2).

• Set the data rate to 9600 baud.

• Set the data format to 8 data bits, 1 stop bit, and no parity.

• Set flow control to none.

• Set the emulation mode to VT100.

• When using HyperTerminal, select Terminal keys, not Windows keys.

WITCH MANAGEMENT

1-4

Notes: 1. When using HyperTerminal with Microsoft® Windows® 2000,

make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.

2. Refer to “Line Commands” on page 3-58 for a complete description of console configuration options.

3. Once you have set up the terminal correctly, the console login screen will be displayed.

For a description of how to use the CLI, see “Using the Command Line Interface” on page 3-1. For a list of all the CLI commands and detailed information on using the CLI, refer to “Command Groups” on page 3-10.

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 is assigned via DHCP by default. To manually configure this address, see “Setting an IP Address” on page 1-7.

Note: The switch supports four concurrent Telnet sessions.

After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network.

ASIC CONFIGURATION

1-5

The onboard 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 5.0 or above, or Netscape Navigator 6.2 or above), or from a network computer using network management software such as EliteView.

Note: The onboard 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 EliteView.

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 utilities. To fully configure switch parameters, you must access the CLI at the Privileged Exec level.

Access to both CLI levels are controlled by user names and passwords. The switch has a default username and password for each level. To log into the CLI at the Privileged Exec level using the default user name and password, perform these steps:

1. To initiate your console connection, press <Enter>. The “User Access Verification” procedure starts.

2. At the Username prompt, enter “admin.”

3. At the Password prompt, also enter “admin.” (The password characters are not displayed on the console screen.)

4. The session is opened and the CLI displays the “Console#” prompt indicating you have access at the Privileged Exec level.

WITCH MANAGEMENT

1-6

Setting Passwords

Note: If this is your first time to log into the CLI program, you should

define new passwords for both default user names using the “username” command, record them and put them in a safe place.

Passwords can consist of up to 8 alphanumeric characters and are case sensitive. To prevent unauthorized access to the switch, set the passwords as follows:

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. Type “username admin password 0 password,” for the Privileged Exec level, where password is your new password. Press <Enter>.

Username: admin Password: CLI session with the host is opened. To end the CLI session, enter [Exit]. Console#configure Console(config)#username guest password 0 [password] Console(config)#username admin password 0 [password] Console(config)#

ASIC CONFIGURATION

1-7

Setting an IP Address

You must establish IP address information for the switch to obtain management access through the network. This can be done in either of the following ways:

Manual — You must input the information, including IP address and subnet mask. If your management station is not in the same IP subnet as the switch, you will also need to specify the default gateway router.

Dynamic — The switch sends IP configuration requests to BOOTP or DHCP servers on the network.

Note: Only one VLAN interface can be assigned an IP address (the

default is VLAN 1.) This defines the management VLAN, the only VLAN through which you can gain management access to the switch. If you assign an IP address to any other VLAN, the new IP address overrides the original IP address and this becomes the new management VLAN.

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. Anything outside this format will not be accepted by the CLI program.

Note: The IP address for the switch is assigned via DHCP by default.

WITCH MANAGEMENT

1-8

Before you can assign an IP address to the switch, you must obtain the following information from your network administrator:

• IP address for the switch

• Default gateway for the network

• Network mask for this network

To assign an IP address to the switch, complete the following steps:

1. From the Privileged Exec level global configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.

2. Type “ip address ip-address netmask,” where ip-address is the switch IP address and netmask is the network mask for the network. Press <Enter>.

3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.

4. To set the IP address of the default gateway for the network to which the switch belongs, type “ip default-gateway gateway,” where gateway is the IP address of the default gateway. Press <Enter>. In the screen below, the IP addresses given are merely examples.

Console(config)#interface vlan 1 Console(config-if)#ip address 192.168.1.5 255.255.255.0 Console(config-if)#exit Console(config)#ip default-gateway 192.168.1.254 Console(config)#

ASIC CONFIGURATION

1-9

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. (BOOTP and DHCP values can include the IP address, subnet mask, and default gateway.)

If the “bootp” or “dhcp” option is saved to the startup-config file, then the switch will start broadcasting service requests as soon as it is powered on.

To automatically configure the switch by communicating with BOOTP or DHCP address allocation servers on the network, complete the following steps:

1. From the Privileged Exec level global configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.

2. At the interface-configuration mode prompt, use one of the following commands:

• To obtain IP settings through DHCP, type “ip address dhcp” and press <Enter>.

• To obtain IP settings through BOOTP, type “ip address bootp” and press <Enter>.

3. Type “exit” to return to the global configuration mode. Press <Enter>.

4. Type “ip dhcp restart” to begin broadcasting service requests. Press <Enter>.

5. Wait a few seconds and then check the IP configuration settings by typing the “show ip interface” command. Press <Enter>.

WITCH MANAGEMENT

6. Save your configuration changes by typing “copy running-config startup-config.” Enter the startup file name and press <Enter>.

Enabling SNMP Management Access

The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as SMC’s 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. The switch can also be configured to send information to SNMP managers (without being requested by the managers) through trap messages that inform the manager that certain events have occurred.

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.

The default strings are:

• public - with read-only access. Authorized management stations are

only able to retrieve MIB objects.

Console(config)#interface vlan 1 Console(config-if)#ip address dhcp Console(config-if)#exit Console#ip dhcp restart Console#show ip interface IP interface vlan IP address and netmask: 10.1.0.54 255.255.255.0 on VLAN 1, and address mode: User specified. Console#copy running-config startup-config Startup configuration file name []: startup

Console#

ASIC CONFIGURATION

1-11

• private - with read-write access. Authorized management stations are able to both retrieve and modify MIB objects.

Note: If you do not intend to use SNMP, it is recommended that you

delete both of the default community strings. If there are no community strings, then SNMP management access to the switch is disabled.

To prevent unauthorized access to the switch via SNMP, it is recommended that you change the default community strings.

To configure a community string, complete the following steps:

1. From the Privileged Exec level global configuration mode prompt,

type “snmp-server community string mode,” where string is the community access string and mode is rw (read/write) or ro (read only). 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. Press <Enter>.

Saving Configuration Settings

Configuration commands only modify the running configuration and are not saved when the switch is rebooted. To save all your configuration changes in nonvolatile storage, you must copy the running configuration to the start-up configuration file using the “copy” command.

To save the current configuration settings, enter the following command:

1. From the Privileged Exec mode prompt, type “copy running-config startup-config” and press <Enter>.

2. Enter the name of the start-up file. Press <Enter>.

Managing System Files

The switch’s file system supports three types of system files that can be managed by the CLI program, Web Interface, or SNMP. The files can be uploaded and downloaded, copied, deleted, and set as a start-up file.

The three types of files are:

• Configuration — These files store system configuration information

and are created when configuration settings are saved. Saved

Console(config)#snmp-server enable traps link-up-down Console(config)#

Console#copy running-config startup-config Startup configuration file name []: startup

Console#

YSTEM DEFAULTS

1-13

configuration files can be selected as a system start-up file or can be uploaded via TFTP to a server for backup. A file named “Factory_Default_Config.cfg” contains the system default settings and cannot be deleted from the system.

• Operation Code — System software that is executed after boot-up, also known as run-time code. This code runs the switch operation and provides the CLI, Web and SNMP management interfaces.

• Diagnostic Code — Software that is run during system boot-up, also known as POST (Power On Self-Test). This code also provides a facility to upload firmware files to the system directly through the console port.

Due to the size limit of the flash memory, the switch supports only two operation code files, and two diagnostic code files. However, you can have as many configuration files as available flash memory space allows.

In the system flash memory, one file of each type must be set as the start-up file. During a system boot, the diagnostic and operation code files set as the start-up file are run, and then the start-up configuration file is loaded.

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.

ONFIGURING THE

WITCH

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: The current firmware does not support stacking, so in all

references to “units” and “ports”, the Unit ID will always be 1.

You can also use the Command Line Interface (CLI) to manage the switch over a serial connection to the console port or via Telnet. For more information on using the CLI, refer to Chapter 3, “Command Line Interface”

Prior to accessing the switch from a Web browser, be sure you have first performed the following tasks:

1. Configure the switch with a valid IP address, subnet mask, and default

gateway using an out-of-band serial connection, BOOTP, or DHCP protocol. (See “Setting the IP Address” on page 2-11.)

2. Set a user name and password using an out-of-band serial connection.

Access to the Web agent is controlled by the same user name and password as the onboard configuration program. (See “Configuring the Login Password” on page 2-14.)

3. 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 Interface Settings” on page 2-41.)

4. After you enter the user name and password, you will have access to the system configuration program.

Setting the IP Address

An IP address may be used for management access to the switch over your network. By default, the switch uses DHCP to assign IP settings to VLAN 1 on the switch. If you wish to manually configure IP settings, you need to set the IP address and netmask to values that are compatible with your network. You may also need to a establish a default gateway between the switch and management stations that exist on another network segment.

You may also need to a establish a default gateway between this device and management stations that exist on another network segment.

Fields and Attributes

• Management VLAN – This is the only VLAN through which you can gain management access to the switch. By default, all ports on the switch are members of VLAN 1, so a management station can be connected to any port on the switch. However, if other VLANs are configured and you change the Management VLAN, you may lose management access to the switch. In this case, you should reconnect the management station to a port that is a member of the Management VLAN.

• IP Address Mode – Specifies whether IP functionality is enabled via manual configuration (Static), Dynamic Host Configuration Protocol (DHCP), or Boot Protocol (BOOTP.) If DHCP/BOOTP is enabled, IP will not function until a reply has been received from the server. Requests will be broadcast periodically by the switch for an IP address. (DHCP/BOOTP values can include the IP address, subnet mask, and default gateway.)

• IP Address – Address of the VLAN interface that is allowed management access. Valid IP addresses consist of four numbers, 0 to 255, separated by periods.

• Subnet Mask – This mask identifies the host address bits used for routing to specific subnets.

ONFIGURING THE SWITCH

• Gateway IP Address – IP address of the gateway router between this device and management stations that exist on other network segments.

• MAC Address – The MAC address of this switch.

Renewing DCHP

DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to another network segment, you will lose management access to the switch. In this case, reboot the switch or submit a client request to restart DHCP service.

Web Interface

If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the Web Interface. You can only restart DHCP service via the Web Interface if the current address is still available.

Command Line Interface

Enter the following command to restart DHCP service.

Security

Configuring the Login Password

The guest only has read access for most configuration parameters. However, 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.

Notes: 1. If you log into the Web interface as guest (Normal Exec level),

you can view page information but only change the guest password. If you log in as admin (Privileged Exec level), you can apply changes on all pages.

2. If your password is lost, contact your local supplier for assistance.

The default guest name is “guest” with the password “guest.” The default administrator name is “admin” with the password “admin.” Note that user names can only be assigned via the CLI.

Configuring Radius Logon Authentication

Remote Authentication Dial-in User Service (RADIUS) is a system that uses a central server running RADIUS software to control access to RADIUS-aware switches on the network. A RADIUS server can be used to create a database of multiple user name/password pairs with associated privilege levels for each user or group that require management access to a switch using the console port, Telnet, or Web.

Fields and Attributes

• Authentication – select the authentication type, or authentication sequence required.

• Server IP Address – the IP address of the RADIUS server.

• Server Port Number – the UDP port number used by the RADIUS server.

• Secret Text String – the text string that is shared between the switch and the RADIUS server.

Configuring Interface Connections

Use the Port Configuration and Trunk Configuration pages to enable/disable an interface, manually set the speed and duplex mode, set flow control, and set auto-negotiation parameters.

Fields and Attributes

• Name – Allows you to label an interface. (Range: 1-64 characters)

• Admin – 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.

• Speed/Duplex – Allows manual selection of port speed and duplex mode (i.e., with auto-negotiation disabled.)

• Flow Control – Allows automatic or manual selection of 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. When enabled, back pressure is used for half-duplex operation and IEEE 802.3x for full-duplex operation.

• Flow control should not be used if a port is connected to a hub.

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 a complete halt.

You can protect your network from broadcast storms by setting a threshold for broadcast traffic for all ports. Any broadcast packets exceeding the specified threshold will then be dropped.

Fields and Attributes

• Broadcast Storm Control default is 500 packets per second.

• Broadcast control does not affect IP multicast traffic.

Web Interface

Click Port/Port Broadcast Control. Set the threshold for all ports (Range: 500 to 262,143 packets per second), and then click “Apply.”

Command Line Interface

Specify the required interface, then enter “Port Security.” To disable this feature enter “No Port Security.”

Address Table Settings

The switch stores the addresses of known devices. This information is used to route traffic directly between the inbound and outbound ports. The addresses learned by monitoring traffic are stored in the dynamic address table. You may also manually configure static addresses that are bound to a specific port.

Displaying the Address Table

The Dynamic Address Table contains the MAC addresses learned by monitoring the source address of traffic entering the switch. When the destination address for inbound traffic is found in the database, packets intended for that address are forwarded directly to the associated port. Otherwise, the traffic is broadcast to all ports.

Command Usage

• Display entries in the dynamic address table by selecting an interface (either port or trunk), MAC address, or VLAN.

• Sort the information displayed based on interface (port or trunk), MAC address, or VLAN.

Web Interface

Click Address Table/Dynamic Addresses. Specify the search type (i.e., Interface, MAC Address, or VLAN), the method of sorting the displayed addresses, and then click “Query.”

PANNING TREE PROTOCOL CONFIGURATION

2-37

Spanning Tree Protocol Configuration

The Spanning Tree Algorithm (STA) detects and disable 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.

Managing Global Settings

Global setting apply to the entire switch.

Fields and Attributes

The following global attributes are read-only and cannot be changed:

• Bridge ID – The priority and MAC address of this device.

• Designated Root – The priority and MAC address of the device in the Spanning Tree that this switch has accepted as the root device.

• Root Port – The number of the port on this switch that is closest to the root. This switch communicates with the root device through this port. If there is no root port, then this switch has been accepted as the root device of the Spanning Tree network.

• Root Path Cost – The path cost from the root port on this switch to the root device.

• Configuration Changes – The number of times the Spanning Tree has been reconfigured.

• Last Topology Change – The time since the Spanning Tree was last reconfigured.

• Hold Time – The minimum interval between the transmission of consecutive Configuration BPDUs. (CLI only.)

The following global attributes can be configured:

• Spanning Tree State – Enable/disable this switch to participate in an STA-compliant network.

ONFIGURING THE SWITCH

2-38

• 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.

• Default: 32768

• Range: 0 - 65535

• Hello Time – Interval (in seconds) at which the root device transmits a configuration message.

•Default: 2

• Minimum: 1

• Maximum: The lower of 10 or [(Max. Message Age / 2) -1]

• 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. 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. (References to “ports” in this section means “interfaces,” which includes both ports and trunks.)

•Default: 20

• Minimum: The higher of 6 or [2 x (Hello Time + 1)]

• Maximum: The lower of 40 or [2 x (Forward Delay - 1)]

• Forward Delay – 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.

•Default: 15

• Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]

•Maximum: 30

Managing Interface Settings

You can configure STA attributes for specific interfaces, including port priority, path cost, and fast forwarding. Use a different priority or path cost for ports of the same media type to indicate the preferred path.

Fields and Attributes

• STA State – Displays the current state of this port within 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 STA configuration messages, but does

not forward packets.

• Listening - Port will leave blocking state due to a topology

change, start transmitting configuration messages, but

will 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 - Port forwards packets, and continues learning

addresses.

• Broken - Port is malfunctioning or no link has been established.

• 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.

Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.

• Default: 128

• Range: 0 - 255

ONFIGURING THE SWITCH

2-42

• Path Cost – This parameter is used by the STA 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.)

•Range:

- Ethernet: 50-600

- Fast Ethernet: 10-60

- Gigabit Ethernet: 3-10

•Default:

- Ethernet - half duplex: 100; full duplex: 95; trunk: 90

- Fast Ethernet - half duplex: 19; full duplex: 18; trunk: 15

- Gigabit Ethernet - full duplex: 4; trunk: 3

• Fast Forward – Since end-nodes cannot cause forwarding loops, they can pass directly through to the forwarding state. Fast Forward can achieve quicker convergence for end-node workstations and servers, and also overcome other STA related timeout problems. (Remember that Fast Forward should only be enabled for ports connected to an end-node device.)

ONFIGURATION

2-45

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. This also provides a more secure and cleaner network environment.

An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but communicate as though they belong to the same physical segment.

VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections. VLANs can be easily organized to reflect departmental groups (such as Marketing or R&D), usage groups (such as e-mail), or multicast groups (used for multimedia applications such as videoconferencing.)

VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN.

• Up to 255 VLANs based on the IEEE 802.1Q standard

• Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol

• Port overlapping, allowing a port to participate in multiple VLANs

• End stations can belong to multiple VLANs

• Priority tagging

ONFIGURING THE SWITCH

2-46

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. Then assign the port at the other end of the link to the same VLAN(s.) However, if you want a port on this switch to participate in one or more VLANs, but the device at the other end of the link does not support VLANs, then you must add this port as an untagged port (that is, a port attached to a 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. If the frame is tagged, the switch uses the tagged VLAN ID to identify the port broadcast domain of the frame.

Port Overlapping – Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by using a Layer-3 router or switch.

Port-based VLANs – Port-based (or static) VLANs are manually tied to specific ports. The switch’s forwarding decision is based on the destination MAC address and its associated port. Therefore, to make valid forwarding or flooding decisions, the switch must learn the relationship of the MAC address to its related port—and thus to the VLAN—at run-time. However, when GVRP is enabled, this process can be fully automatic.

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

VLAN C

ONFIGURATION

2-47

groups it wants to join. When this switch receives these messages, it will automatically place the receiving port in the specified VLANs and forward the message to all other ports. When the message arrives at another switch that supports GVRP, it will also place the receiving port in the specified VLANs and pass the message on to all other ports. VLAN requirements are propagated in this way throughout the network. This allows GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests.

To implement GVRP in a network, you must first configure the static VLANs required on switches that are connected to PCs, servers, and other devices, so that these VLANs can be propagated across the network (Web - VLAN/VLAN Static Membership.) For other core switches in the network, enable GVRP on the links between these devices. (Web - VLAN/Port Configuration or Trunk Configuration.)

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.

Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is therefore capable of passing tagged or untagged frames. To forward a frame from a VLAN-aware device to a VLAN-unaware device, the switch first decides where to forward the frame, and then strips off the VLAN tag. However, to forward a frame from a VLAN-unaware device to a VLAN-aware device, the switch first decides where to forward the frame, and then inserts a VLAN tag reflecting this port’s default VID.

ONFIGURING THE SWITCH

2-48

Enabling or Disabling GVRP (Global Setting)

GARP VLAN Registration Protocol (GVRP) defines a way 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. GVRP must be enabled to permit automatic VLAN registration, and to support VLANs which extend beyond the local switch. (Default: Enabled.)

Configuring VLAN Behavior for Interfaces

You can configure VLAN behavior for specific interfaces, including 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.

• GARP – Group Address Registration Protocol is used by GVRP to register or deregister client attributes for client services within a bridged LAN. The default values for the GARP timers are independent of the media access method or data rate. These values should not be changed unless you are experiencing difficulties with GVRP registration/deregistration.

Fields and Attributes

• PVID – The VLAN ID assigned to untagged frames received on the interface. If the (CLI) switchport mode is set to trunk (see page 3-99), the PVID will be inserted into all untagged frames sent from a tagged port. (Default: 1.)

• Acceptable Frame Type – Sets the interface to accept all frame types 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. (Default: All.)

• Ingress Filtering – If ingress filtering is enabled, incoming frames for VLANs which do not include this ingress port in their member set will be discarded at the ingress port. This will not affect VLAN independent BPDU frames, such as GVRP or STP. (Default: Disabled.)

• 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 2-22) When disabled, any GVRP packets received on this port will be discarded and no GVRP registrations will be propagated from other ports. (Default: Enabled.)

• GARP Join Timer – The interval between transmitting requests/ queries to participate in a VLAN group. (Default: 20 centiseconds) (Range: 20-1000 centiseconds; Default: 20 centiseconds)

- Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer.

• 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. (Range: 60-3000 centiseconds; Default: 60 centiseconds)

- Timer settings must follow this rule: 2 x (join timer) < leave timer <leaveAll timer.

• GARP LeaveAll Timer – The interval between sending out a LeaveAll query message for VLAN group participants and the port leaving the group. This interval should be considerably larger than the Leave Time to minimize the amount of traffic generated by nodes rejoining the group. (Range: 500-18000 centiseconds; Default: 1000 centiseconds.)

- Timer settings must follow this rule: 2 x (join timer) < leave timer <leaveAll timer.

• Trunk Member – Indicates if a port is a member of a trunk. To add a trunk to the selected VLAN, use the last table on the VLAN Static Table page.

ONFIGURING THE SWITCH

2-58

• Mode – Indicates VLAN membership mode for a port. (Configure via CLI, see page 3-99.)

• Trunk – Specifies a port as an end-point for a VLAN trunk. A

trunk is a direct link between two switches, so the port transmits and receives tagged frames that identify the source VLAN.

• Hybrid – Specifies a hybrid VLAN interface. The port may

receive or transmit tagged or untagged frames. Any frames that are not tagged will be assigned to the default VLAN.

Web Interface

Click VLAN/VLAN Trunk Configuration or VLAN Port Configuration. Fill in the required settings for each interface, click “Apply.”

Command Line Interface

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.

Configuring Private VLANs

A Private VLAN allows modification of the default VLAN to provide port-based security and isolation between ports within the VLAN. Data traffic on downlink ports can only be forwarded to, and from, uplink ports. Private VLANs and normal VLANs can exist simultaneously within the same switch. Both individual ports and port trunks can be configured as downlink or uplink interfaces.

Enabling Private VLANs

Use the Private VLAN Status page to enable/disable the Private VLAN function.

Web Interface

Click Private VLAN/Private VLAN Status, then select Enabled/Disabled to enable or disable the Private VLAN function.

Command Line Interface

This example enables private VLANs.

Configuring Uplink and Downlink Ports

Use the Private VLAN Status and Private VLAN Status Link pages to enable/disable the Private VLAN function and to configure port groups as downlink or uplink ports.

When one port in a group is configured as a downlink or uplink port, all other ports in that group are also configured as downlink or uplink ports. The Web and Command Line Interface however, will only display the explicitly configured port as a downlink or uplink port.

Console(config)#pvlan 3-105 Console(config)#

ONFIGURING THE SWITCH

Downlink ports and uplink ports can only be configured in certain

groups.

For example, on the Web screen shown on the following page, only trunk 1 displays as a downlink interface. However, since ports 9 and 17 are members of trunk 1, ports 9-24 would all be configured as downlink ports.

Fields and Attributes

• Private VLAN Status – Enables/disables the Private VLAN function.

• Uplink – Configures the port as an uplink port.

• Downlink – Configures the port as a downlink port.

• None – If selected, the port does not belong to the private VLAN.

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. You can set the default priority for each interface, and configure the mapping of frame priority tags to the switch’s priority queues.

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.

Command Usage

• This switch provides four priority queues for each port. It uses Weighted Round Robin to prevent head-of-queue blockage.

• The default priority applies if the incoming frame is an untagged frame received from a VLAN trunk or a static-access port. This priority does not apply to IEEE 802.1Q VLAN tagged frames. If the incoming frame is an IEEE 802.1Q VLAN tagged frame, the IEEE 802.1p User Priority bits will be used.

• If the output port is an untagged member of the associated VLAN, these frames are stripped of all VLAN tags prior to transmission.

Fields and Attributes

• Default Priority – The priority that is assigned to untagged frames received on the specified port. (Range: 0 - 7, Default: 0.)

• Number of Egress Traffic Classes – The number of queue buffers provided for each port.

Mapping Priority Classes to Egress Queues

This switch supports Class of Service by using four priority queues, with Weighted Round Robin Queuing for each port. Eight traffic classes 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

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.

Note that the mapping of CoS priorities to switch output queues for any single port then applies to all ports on the switch.

Queue Scheduling

In the Queue Scheduling page, you can configure Weighted Round Robin (WRR) queueing for the switch. Note that setting weight values for traffic classes for any single port then applies to all the ports on the switch.

Mapping Layer 3/4 Priorities to CoS Values

This switch supports several common methods of prioritizing layer 3/4 traffic to meet application requirements. Traffic priorities can be specified in the IP header of a frame, using the priority bits in the Type of Service (ToS) octet or the number of the TCP/UDP port. If priority bits are used, the ToS octet may contain three bits for IP Precedence or six bits for Differentiated Services Code Point (DSCP) service. When these services are enabled, the priorities are mapped to a Class of Service value by the switch, and the traffic then sent to the corresponding output queue.

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.

• IP Precedence and DSCP Priority cannot both be enabled. Enabling one of these priority types will automatically disable the other.

ONFIGURING THE SWITCH

2-70

Mapping IP Precedence

The Type of Service (ToS) octet in the IPv4 header includes three precedence bits defining eight priority levels ranging from highest priority for network control packets to lowest priority for routine traffic. Bits 6 and 7 are used for network control, and the other bits for various application types. The ToS bits are defined in the following table.

Fields and Attributes

• IP Precedence/DSCP Priority Status – Selects IP Precedence, DSCP, or disables both priority services.

• IP Precedence Priority Table – Shows the IP Precedence to CoS map.

• Class of Service Value – Maps a CoS value to the selected IP Precedence value. Note that “0” represents low priority and “7” represents high priority.
