Introduction

The 1Gb Intelligent L2 Switch provides two switch modes: The conventional L2 switch mode, and SmartPanel mode. The switch can store up to two different software image, called image1 and image2. Normally, the conventional L2 switch software image is stored in image1, and the SmartPanel software is stored in image2. You can select which software image (image1 or image2) you want to run in switch memory. By default, the switch software is loaded from image1. To run the SmartPanel software, you need to change a software image to image2 and reboot the switch. See additional references for configuration to select a software image.

This guide explains how to configure the switch in running the SmartPanel software. The SmartPanel provides a simple Ethernet interface option for connecting to the network infrastructure. The number and type of configuration options on the SmartPanel are restricted to reduce the initial setup complexity and to minimize the impact on upstream networking devices.

Additional references

Additional information about installing and configuring the switch is available in the following guides, which are attached in this product.

Management Network

The 1Gb Intelligent L2 Switch is a Switch Module within the Blade Enclosure. The Blade Enclosure includes an Enclosure Manager Card which manages the modules and CPU Blades in the enclosure.

The 1Gb Intelligent L2 Switch communicates with the Enclosure Manager Card through its internal management port (port 19). The factory default settings permit management and control access to the switch through the 10/100 Mbps Ethernet port on the Blade Enclosure, or the built-in console port.

The switch management network has the following characteristics:

Port 19 — Management port 19 has the following configuration:

Flow control: both Auto-negotiation Untagged Port VLAN ID (PVID): 4095

VLAN 4095 — Management VLAN 4095 isolates management traffic within the switch. VLAN 4095 contains

only one member port (port 19). No other ports can be members of VLAN 4095.

Interface 256 — Management interface 256 is associated with VLAN 4095. No other interfaces can be

associated with VLAN 4095. The IP address of the management interface is assigned through Dynamic Host Control Protocol (DHCP).

Gateway 4 — This gateway is the default gateway for the management interface.

Connecting to the switch

You can access the command line interface in one of the following ways:

Using a console connection via the console port Using a Telnet connection over the network Using a Secure Shell (SSH) connection to securely log in over a network Using a HTTP connection over the network

Establishing a console connection

To establish a console connection with the switch, you need:

A null modem cable with a female DB-9 connector (See the User’s Guide for more information.) An ASCII terminal or a computer running terminal emulation software set to the parameters shown in the table

below

To establish a console connection with the switch:

1. Connect the terminal to the console port using the null modem cable.

2. Power on the terminal.

3. Press the Enter key a few times on the terminal to establish the connection.

4. You will be required to enter a password for access to the switch. (For more information, see the “Accessing the switch” section later in this chapter.)

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 6

Setting an IP address

NOTE: You can assign the IP address only on the management port 19.

telnet <1Gb Intelligent L2 Switch IP address>

NOTE: It is recommended that you change default switch passwords after initial configuration and as

regularly as required under your network security policies. For more information, see the “Setting passwords”

section in the “First-time configuration” chapter.

To access the switch via a Telnet, an SSH connection, or an HTTP connection, you need to have an Internet Protocol (IP) address set for the switch. You can assign the IP address only to the management interface (interface

256), associated with port 19. The management interface requests its IP address from a Dynamic Host Control

Protocol (DHCP) server on the Enclosure Manager Card. See the User’s Guide of the Enclosure Manager Card for configuration to assign the IP address to the switch modules.

Establishing a Telnet connection

A Telnet connection offers the convenience of accessing the switch from any workstation connected to the network. Telnet provides the same options for user, operator, and administrator access as those available through the console port. By default, Telnet is enabled on the switch. The switch supports four concurrent Telnet connections.

Once the IP parameters are configured, you can access the CLI using a Telnet connection. To establish a Telnet connection with the switch, run the Telnet program on the workstation and enter the telnet command, followed by the switch IP address:

You will then be prompted to enter a password. The password entered determines the access level: administrator, operator, or user. See the “Accessing the switch” section later in this chapter for description of default passwords.

Establishing an SSH connection

Although a remote network administrator can manage the configuration of a switch via Telnet, this method does not provide a secure connection. The Secure Shell (SSH) protocol enables you to securely log into the switch over the network.

As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over the

network is encrypted and secure. In order to use SSH, you must first configure it on the switch. See the “Secure

Shell Server configuration” section in the “Configuration Menu” chapter for information on how to configure SSH.

Establishing an HTTP connection

By default, HTTP is enabled on the switch. You can configure the switch using the Web browser. For more information, see the “Browser-based interface” chapter.

Accessing the switch

To enable better switch management and user accountability, the switch provides different levels or classes of user access. Levels of access to the CLI and Web management functions and screens increase as needed to perform various switch management tasks. The three levels of access are:

User—User interaction with the switch is completely passive; nothing can be changed on the switch. Users

may display information that has no security or privacy implications, such as switch statistics and current operational state information.

Operator—Operators can only effect temporary changes on the switch. These changes will be lost when the

switch is rebooted/reset. Operators have access to the switch management features used for daily switch operations. Because any changes an operator makes are undone by a reset of the switch, operators cannot severely impact switch operation, but do have access to the Maintenance menu.

Administrator—Only administrators can make permanent changes to the switch configuration, changes that

are persistent across a reboot/reset of the switch. Administrators can access switch functions to configure and troubleshoot problems on the switch. Because administrators can also make temporary (operator-level) changes as well, they must be aware of the interactions between temporary and permanent changes.

Access to switch functions is controlled through the use of unique usernames and passwords. Once you are connected to the switch via the local console, Telnet, or SSH, you are prompted to enter a password. The password entered determines the access level. The default user names/password for each access level is listed in the following table. Once you are connected to the switch via HTTP, you are prompted to enter a user account and password.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 7

Table 3 User access levels

User account

Description and tasks performed

user

Browser-based interface

NOTE: JavaScript is not the same as Java™. Be sure that JavaScript is enabled in your Web browser.

Introduction

This chapter explains how to access the switch browser-based interface (BBI) for the SmartPanel and configure the switch.

Requirements

To use the browser-based interface, you need the following:

PC or workstation with network access to the switch Frame-capable Web-browser software, such as the following:

Netscape Navigator 4.7x or higher Internet Explorer 6.0x or higher

JavaScript enabled in your Web browser

Web browser setup

Most modern Web browsers work with frames and JavaScript by default, and require no additional set up.

However, you should check your Web browser’s features and configuration to be sure frames and JavaScript are

enabled.

Starting the BBI

When the switch and browser setup is complete, follow these steps to launch the BBI:

1. Start your Web browser.

2. Enter the switch IP interface address in the Web browser Uniform Resource Locator (URL) field. For example, if the switch IP interface has a network IP address of 192.168.3.70. Using Internet Explorer, you

could enter the following (for secure BBI access, use https://).

If you do not use the default TCP port number (80) for BBI access, you can include the port number when you enter the IP address:

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 9

NOTE: There may be a slight delay while the Port Group Mapping page is initializing. You should not stop the browser while loading is in progress.

If the switch IP interface address has a name on your local domain name server, you can enter the name instead. Using Internet Explorer, you can enter the following:

3. Log in to the switch. If your switch and browser are properly configured, you will be asked to enter a password.

Enter the account name and password for the switch.

4. Allow the BBI Dashboard page to load. When the proper account name and password combination is entered, the BBI Port Group Mapping page is

displayed in the browser viewing area.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 12

Port Group Mapping

NOTE: Cross-connect ports (17-18) are not available in the SmartPanel.

SmartPanel ports can be combined into Port Groups. Up to five Port Groups are available in the SmartPanel. A Spare Ports Group is available for unused ports.

VLANs and Link Aggregation Groups (trunks) are configured automatically for each Port Group. No network loops are allowed in the configuration. All external ports in the Port Group form a trunk group (static trunk or Link Aggregation Group).

Port Group Characteristics

SmartPanel Port Groups must have the following characteristics.

Each Port Group must contain at least one external port (20-24) and one internal server blade port (1-16). All external ports in a Port Group must have the same configuration. Each port in the Port Group is a member of a unique, untagged VLAN. Tagged VLANs (1-4094) can be assigned to each Port Group. Tagged VLANs cannot be configured across

multiple Port Groups.

All external ports in the Port Group form a trunk group.

Port Group configuration

On the BBI, choose Port Group Mapping to select the Port Group for each of the external ports and server blade ports. Click Apply to make the changes active. Click Save to write the configuration to flash memory.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 13

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 15

NOTE: Spare Ports Group for unused ports is assigned a PVID.

NOTE: The SmartPanel does not permit configuration of tagged VLANs across multiple Ports Groups.

VLAN

Virtual LANs (VLANs) are commonly used to split up groups of network users into manageable broadcast domains, to create logical segmentation of workgroups, and to enforce security policies among logical segments. This switch supports up to 1,000 VLANs per switch. Even though the maximum number of VLANs supported at any given time is 1,000, each can be identified with any number between 1 and 4095. VLAN 4095 is used by the management network, which includes the management port 19. VLAN 4095 configuration cannot be modified.

PVID

Each Port Group has a configurable default VLAN number, known as its PVID (Port VLAN ID). All ports are set as untagged members of PVID. By default, all ports except port 19 are configured as Group1. The PVID of Group1 is 1.

The unique value of PVID is assigned to the Port Group, which contains at least one external port and one internal server blade port. For the configuration, see the “Port VLAN ID configuration” section later in this chapter.

802.1Q VLAN Tagging

802.1Q VLAN tagging provides standards-based VLAN support for Ethernet systems. This standard permits

multiple VLANs to be transmitted over a single Ethernet connection. Tagging places the VLAN identifier in the frame header of a packet, allowing each port to belong to multiple VLANs.

For the configuration to add the VLAN ID to the Port Group, see the “Non-Default Virtual LANs” section later in this chapter.

Port VLAN ID configuration

Assign at lease one external port and one internal blade server port to the Port Group to use it and assign a unique value of PVID. On the BBI, choose System settings > Uplink/Group to change the PVID. Edit the value of the following Port VLAN ID. The value of unused Port Group is 0.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 21

NOTE: Because all ports in a Port Group belong to the same trunk group, individual external ports cannot be used as a regular 802.3 link. Do not plug a workstation directly into one of the SmartPanel’s external ports, unless that is the only device plugged into the ports.

Trunking

Trunk groups provide super-bandwidth, multi-link connections between SmartPanel or other trunk-capable devices. A trunk group is a group of ports that act together, combining their bandwidth to create a single, larger virtual link.

SmartPanel trunk groups are static link aggregation groups that are compatible with Cisco’s EtherChannel technology.

The SmartPanel is statically configured to place each Port Group into a separate trunk group.

When using port trunk groups between the SmartPanel and a switch, you can create a virtual link, operating at up to 5 Gigabits per second, depending on how many physical ports are combined.

Statistical Load Distribution

Network traffic is statistically distributed between ports in a trunk group. The SmartPanel uses the source and destination IP address information present in each transmitted IP frame to determine load distribution. If the frame is not an IP frame, then Layer 2 MAC addresses are used.

Each packet’s particular combination of source and destination addresses results in selecting one line in the trunk group for data transmission. If there are enough devices feeding the trunk lines, then traffic distribution becomes relatively even.

Built-In Fault Tolerance

Since trunk groups are comprised of multiple physical links, each trunk group is inherently fault tolerant. As long as one connection is available, the trunk remains active.

Statistical load balancing is maintained whenever a port in a trunk group is lost or returned to service.

Trunk group configuration rules

The trunking feature operates according to specific configuration rules. When working with trunks, consider the following rules that determine how a trunk group reacts in any network topology.

All trunks must originate from one device, and lead to one destination device. Trunking from third-party devices must comply with Cisco® EtherChannel® technology. All external ports in a Port Group must have the same configuration. Only external ports in a Port Group are trunked. For Port Group configuration, see the “Port Group

configuration”.

Link Aggregation Control Protocol

Link Aggregation Control Protocol (LACP) is an IEEE 802.3ad standard for grouping several physical ports into one logical port (known as a dynamic trunk group or Link Aggregation Group) with any device that supports the standard. Please refer to IEEE 802.3ad-2002 for a full description of the standard.

The 802.3ad standard allows standard Ethernet links to form a single Layer 2 link using the Link Aggregation Control Protocol (LACP). Link aggregation is a method of grouping physical link segments of the same media type and speed in full duplex, and treating them as if they were part of a single, logical link segment. If a link in a LACP trunk group fails, traffic is reassigned dynamically to the remaining link/s of the dynamic trunk group.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 22

Trunk Group configuration

On the BBI, choose System Settings > Uplink/Group to enable or disable the Link Aggregation Control Protocol. When enabled, the external ports are configured as a LACP trunk group. When disabled, they are configured as a static trunk group. The default is disabled.

Failover

The primary application for Failover is to support Network Adapter Teaming. With Network Adapter Teaming, the NICs on each server all share the same IP address, and are configured into a team. One NIC is the primary link, and the other is a standby link.

Failover is enabled by default. You can enable or disable Failover on a Port Group. When enabled, Failover works as follows.

If some (or all) of the links fail in the failover trigger, the SmartPanel disables all internal ports of the Port

Group. When the internal ports are disabled, it causes the NIC team on the affected server blade to failover from the primary to the backup NIC. This process is called a failover event.

When the appropriate links return to service, the SmartPanel enables the internal ports of the Port Group.

This causes the NIC team on the affected server blades to fail back to the primary SmartPanel (unless AutoFallback is disabled on the NIC team). The backup processes traffic until the primary’s internal links come up, which takes up to five seconds.

The failover limit lets you specify the minimum number of operational links required within the failover trigger before the trigger initiates a failover event. For example, if the limit is four, a failover event occurs when the number of operational links in the trigger is four or fewer. When you set the limit to all, the SmartPanel triggers a failover event only when no links in the trigger are operational. The default is all.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 23

Failover configuration

On the BBI, choose System Settings > Uplink/Group to configure the Switch Failover and Number of Links to Trigger Failover.

IGMP Snooping

IGMP Snooping allows the SmartPanel to forward multicast traffic only to those ports that request it. IGMP Snooping prevents multicast traffic from being flooded to all ports. The SmartPanel learns which server hosts are interested in receiving multicast traffic, and forwards it only to ports connected to those servers.

On the BBI, choose System Settings > IGMP Snooping to enable IGMP Snooping. The default is disabled.

Description

dot1PortInFrames

The number of frames that have been received by this port from its segment. A frame received on the interface corresponding to this port is counted by this object, if and only if, it is for a protocol being processed by the local bridging function, including bridge management frames.

dot1PortOutFrames

The number of frames that have been transmitted by this port to its segment. A frame transmitted on the interface corresponding to this port is counted by this object, if and only if, it is for a protocol being processed by the local bridging function, including bridge management frames.

dot1PortInDiscards

Count of valid frames received which were discarded (that is, filtered) by the forwarding process.

dot1TpLearnedEntryDiscards

The total number of Forwarding Database entries, which have been or would have been learned, but have been discarded due to a lack of space to store them in the Forwarding Database. If this counter is increasing, it indicates that the Forwarding Database is regularly becoming full (a condition which has adverse performance effects on the sub network). If this counter has a significant value but is not presently increasing, it indicates that the problem has been occurring but is not persistent.

Statistics

Description

dot3StatsAlignmentErrors

A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the Frame Check Sequence (FCS) check. The count represented by an instance of this object is incremented when the alignmentError status is returned by the MAC service to the Logical Link Control (LLC) (or other MAC user). Received frames for which multiple error conditions obtained are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.

dot3StatsFCSErrors

A count of frames received on a particular interface that are an integral number of octets in length but do not pass the Frame Check Sequence (FCS) check. The count represented by an instance of this object is incremented when the frameCheckError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtained are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.

dot3StatsSingleCollisionFrames

A count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the corresponding instance of the dot3StatsMultipleCollisionFrame object.

dot3StatsMultipleCollisionFrames

A count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the corresponding instance of the dot3StatsSingleCollisionFrames object.

dot3StatsLateCollisions

The number of times that a collision is detected on a particular interface later than 512 bit-times into the transmission of a packet. Five hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 Mbit/s system. A (late) collision included in a count represented by an instance of this object is also considered as a (generic) collision for purposes of other collision-related statistics.

dot3StatsExcessiveCollisions

A count of frames for which transmission on a particular interface fails due to excessive collisions.

Table 37 Ethernet statistics for port

Statistics

Description

dot3StatsInternalMacTransmitErrors

A count of frames for which transmission on a particular interface fails due to an internal MAC sublayer transmit error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions object, or the dot3StatsCarrierSenseErrors object. The precise meaning of the count represented by an instance of this object is implementation specific. In particular, an instance of this object may represent a count of transmission errors on a particular interface that are not otherwise counted.

dot3StatsFrameTooLongs

A count of frames received on a particular interface that exceeds the maximum permitted frame size. The count represented by an instance of this object is incremented when the frameTooLong status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtained are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.

dot3StatsInternalMacReceiveErrors

A count of frames for which reception on a particular interface fails due to an internal MAC sublayer receive error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of the dot3StatsFrameTooLongs object, the dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors object. The precise meaning of the count represented by an instance of this object is implementation specific. In particular, an instance of this object may represent a count of received errors on a particular interface that are not otherwise counted.

The total number of input datagrams received from interfaces, including those received in error.

ipInHdrErrors

The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, and so on.

ipInAddrErrors

The number of input datagrams discarded because the IP address in their IP header destination field was not a valid address to be received at this switch. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported classes (for example, Class E). For entities which are not IP gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.

Introduction

The Configuration Menu is only available from an administrator login. It includes submenus for configuring every aspect of the switch. Changes to configuration are not active until explicitly applied. Changes can be saved to nonvolatile memory (NVRAM).

Menu information

Command: /cfg

The following table describes the Configuration Menu options.

Viewing, applying, reverting, and saving changes

As you use the configuration menus to set switch parameters, the changes you make do not take effect immediately. All changes are considered pending until you explicitly apply them. Also, any changes are lost the next time the switch boots unless the changes are explicitly saved.

While configuration changes are in the pending state, you can:

View the pending changes Apply the pending changes Revert to restore configuration parameters set with the last apply command Save the changes to flash memory

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 62

Viewing pending changes

# diff

# diff flash

# apply

NOTE: All configuration changes take effect immediately when applied.

# revert

IMPORTANT: If you do not save the changes, they will be lost the next time the system is rebooted.

# save

# save n

You can view all pending configuration changes by entering diff at any CLI prompt:

You can view all pending configuration changes that have been applied but not saved to flash memory by entering diff flash at any CLI prompt:

Applying pending changes

To make your configuration changes active, you must apply them. To apply configuration changes, enter the following command at any prompt:

Reverting changes

The revert command removes configuration changes that have been made, but not applied. Enter revert apply to remove all changes that have not been saved:

Saving the configuration

In addition to applying the configuration changes, you can save them to flash memory on the switch.

To save the new configuration, enter the following command at any prompt:

When you save configuration changes, the changes are saved to the active configuration block. The configuration being replaced by the save is first copied to the backup configuration block. If you do not want the previous configuration block copied to the backup configuration block, enter the following instead:

You can decide which configuration you want to run the next time you reset the switch. Your options include:

The active configuration block The backup configuration block Factory default configuration block

You can view all pending configuration changes that have been applied but not saved to flash memory using the diff flash command. It is a global command that can be executed from any prompt.

bckdoor enable|disable

Enables or disables the RADIUS back door for telnet/SSH/ HTTP/HTTPS. The default value is disabled. This command does not apply when secure backdoor (secbd) is enabled.

secbd enable|disable

Enables or disables the RADIUS back door using secure password for telnet/SSH/ HTTP/HTTPS. The default value is disabled. This command does not apply when backdoor (bckdoor) is enabled.

Enables the RADIUS server.

off

Disables the RADIUS server. This is the default.

cur

Displays the current RADIUS server parameters.

IMPORTANT: If RADIUS is enabled, you must login using RADIUS authentication when connecting via the console or Telnet/SSH/HTTP/HTTPS.

TACACS+ server configuration

Command: /cfg/sys/tacacs+

TACACS+ (Terminal Access Controller Access Control System) is an authentication protocol that allows a remote access server to forward a user's logon password to an authentication server to determine whether access can be allowed to a given system. TACACS+ and Remote Authentication Dial-In User Service (RADIUS) protocols are more secure than the TACACS encryption protocol. TACACS+ is described in RFC 1492.

TACACS+ protocol is more reliable than RADIUS, as TACACS+ uses the Transmission Control Protocol (TCP) whereas RADIUS uses the User Datagram Protocol (UDP). Also, RADIUS combines authentication and authorization in a user profile, whereas TACACS+ separates the two operations.

TACACS+ offers the following advantages over RADIUS as the authentication device:

TACACS+ is TCP-based, so it facilitates connection-oriented traffic. It supports full-packet encryption, as opposed to password-only in authentication requests. It supports decoupled authentication, authorization, and accounting.

The following table describes the TACACS+ Server Configuration Menu options.

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 68

IMPORTANT: If TACACS+ is enabled, you must login using TACACS+ authentication when connecting via the console or Telnet/SSH/HTTP/HTTPS. Backdoor for console is always enabled, so you can connect using notacacs and the administrator password even if the backdoor (bckdoor) or secure backdoor (secbd) are disabled.

If backdoor is enabled (bckdoor ena), type in notacacs as a backdoor to bypass TACACS+ checking, and use the administrator password to log into the switch. The switch allows this even if TACACS+ servers are available.

If secure backdoor is enabled (secbd ena), type in notacacs as a backdoor to bypass TACACS+ checking, and use the administrator password to log into the switch. The switch allows this only if TACACS+ servers are not available.

Command: /cfg/sys/ssnmp

The switch software supports SNMP-based network management. In SNMP model of network management, a management station (client/manager) accesses a set of variables known as MIBs (Management Information Base) provided by the managed device (agent). If you are running an SNMP network management station on your network, you can manage the switch using the following standard SNMP MIBs:

MIB II (RFC 1213) Ethernet MIB (RFC 1643) Bridge MIB (RFC 1493)

An SNMP agent is a software process on the managed device that listens on UDP port 161 for SNMP messages. Each SNMP message sent to the agent contains a list of management objects to retrieve or to modify.

SNMP parameters that can be modified include: System name System location System contact Use of the SNMP system authentication trap function Read community string Write community string

Introduction

You must be logged in to the switch as the administrator to use the Boot Options Menu. The Boot Options Menu provides options for:

Selecting a switch software image to be used when the switch is next reset. Selecting a configuration block to be used when the switch is next reset. Downloading or uploading a new software image to the switch via FTP or TFTP.

Menu information

Command: /boot

Each of the Boot Options Menu commands is discussed in greater detail in the following sections.

Updating the switch software image

The switch software image is the executable code running on the switch. A version of the image ships with the switch, and comes pre-installed on the device. As new versions of the image are released, you can upgrade the software running on the switch.

Upgrading the software image on the switch requires the following:

Loading the new image onto a FTP or TFTP server on your network Downloading the new image from the FTP or TFTP server to the switch Selecting the new software image to be loaded into switch memory the next time the switch is reset

Downloading new software to the switch

The switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you download new software, you must specify where it should be placed: either into image1, image2, or boot.

By default, the software for conventional Layer2 switch mode is stored in image1 and the software for SmartPanel mode is stored in image2.

To download new software to the switch, you will need the following:

The image or boot software loaded on a FTP or TFTP server on your network The IP address of the FTP or TFTP server The name of the new software image or boot file

When the above requirements are met, use the following procedure to download the new software to the switch.

1. At the Boot Options# prompt, enter:

2. Enter the name of the switch software to be replaced:

3. Enter the IP address of the FTP or TFTP server:

4. Enter the name of the new software file on the server:

6. Enter the password for the FTP server (if prompted):

7. The system then requests confirmation of what you have entered. To have the file uploaded, enter y.

Selecting a configuration block

When you make configuration changes to the switch, you must save the changes so that they are retained beyond the next time the switch is reset. When you execute the save command, your new configuration changes are placed in the active configuration block. The previous configuration is copied into the backup configuration block.

There is also a factory configuration block. This holds the default configuration set by the factory when the switch was manufactured. Under certain circumstances, it may be desirable to reset the switch configuration to the default. This can be useful when a custom-configured switch is moved to a network environment where it will be reconfigured for a different purpose.

Use the following procedure to set which configuration block you want the switch to load the next time it is reset:

1. At the Boot Options# prompt, enter:

2. Enter the name of the configuration block you want the switch to use. The system indicates which configuration block is currently set to be loaded at the next reset, and prompts

you to enter a new choice:
