Stacking Overview

PowerConnect 3424/P and PowerConnect 3448/P stacking provides multiple switch management through a single point as if all stack members are a single unit. All stack members are accessed through a single IP address through which the stack is managed. The stack is managed from a:

• Web-based interface

• SNMP Management Station

• Command Line Interface (CLI)

PowerConnect 3424/P and PowerConnect 3448/P devices support stacking up to six units per stack, or can operate as stand-alone units.

During the Stacking setup, one switch is selected as the Stack Master and another stacking member can be selected as the Backup Master. All other devices are selected as stack members, and assigned a unique Unit ID.

Switch software is downloaded separately for each stack members. However, all units in the stack must be running the same software version.

Switch stacking and configuration is maintained by the Stack Master. The Stack Master detects and reconfigures the ports with minimal operational impact in the event of:

• Unit Failure

• Inter-unit Stacking Link Failure

• Unit Insertion

• Removal of a Stacking Unit

22 Introduction

Page 23

Understanding the Stack Topology

The PowerConnect 3400 series operates in a Ring topology. A stacked Ring topology is where all devices in the stack are connected to each other forming a circle. Each device in the stack accepts data and sends it to the device to which it is attached. The packet continues through the stack until it reaches its destination. The system discovers the optimal path on which to send traffic.

Figure 1-3. Stacking Ring Topology

Ring Topology

Most difficulties incurred in Ring topologies occur when a device in the ring becomes nonfunctional, or a link is severed. With the PowerConnect 3424/P and PowerConnect 3448/P stack, the system automatically switches to a Stacking Failover topology without any system downtime. An SNMP message is automatically generated, but no stack management action is required. However, the stacking link or stacking member must be repaired to ensure the stacking integrity.

After the stacking issues are resolved, the device can be reconnected to the stack without interruption, and the Ring topology is restored.

Stacking Failover Topology

If a failure occurs in the stacking topology, the stack reverts to Stacking Failover Topology. In the Stacking Failover topology, devices operate in a chain formation. The Stack Master determines where the packets are sent. Each unit is connected to two neighboring devices, except for the top and bottom units.

Stacking Members and Unit ID

Stacking Unit IDs are essential to the stacking configuration. The stacking operation is determined during the boot process. The operation mode is determined by the Unit ID selected during the initialization process. For example, if the user selected the stand-alone mode, the device boots in the boot-up process as a stand-alone device.

The device units are shipped with a default Unit ID of the stand-alone unit. If the device is operating as a stand-alone unit, all stacking LEDs are off.

Introduction 23

Page 24

Once the user selects a different Unit ID, it is not erased, and remains valid, even if the unit is reset.

Unit ID 1 and Unit ID 2 are reserved for Master enabled units. Unit IDs 3 to 6 can be defined for stack members.

When the Master unit boots or when inserting or removing a stack member, the Master unit initiates a stacking discovering process.

NOTE: If two members are discovered with the same Unit ID the stack continues to function, however

only the unit with the older join time joins the stack. A message is sent to the user, notifying that a unit failed to join the stack.

Removing and Replacing Stacking Members

www.dell.com | support.dell.com

Unit 1 and Unit 2 are Master enabled units. Unit 1 and Unit 2 are either designated as Master Unit or Backup Master Unit. The stack Master assignment is performed during the configuration process. One Master enabled stack member is elected as Master, and the other Master enabled stack member is elected as Backup Master, according to the following decision process:

• If only one Stack Master enabled unit is present, it is elected as the Master.

• If two Master enabled stacking members are present, and one has been manually configured as the Stack Master, the manually configured member is elected as Stack Master.

• If two Master enabled units are present and neither has been manually configured as the Master, the one with the longer up-time is elected as the Stack Master.

• If two Master enabled units are present and both have been manually configured as the Master, the one with the longer up-time is elected as the Stack Master.

• If the two Master enabled stacking members are the same age, Unit 1 is elected as the Stack Master.

For example, Unit 2 is inserted in the first minute of a ten-minute cycle, and Unit 1 is inserted in fifth minute of the same cycle, the units are considered to be the same age. If there are two Master enabled stack members that are the same age, then Unit 1 is elected master.

The Stack Master and the Backup Master maintain a Warm Standby. The Warm Standby ensures that the Backup Master takes over for the Stack Master if a failover occurs. This guarantees that the stack continues to operate normally.

During the Warm Standby, the Master and the Backup Master are synchronized with the static configuration only. When the Stacking Master is configured, the Stack Master must synchronize the Stacking Backup Master. The Dynamic configuration is not saved, for example, dynamically learned MAC addresses are not saved.

Each port in the stack has a specific Unit ID, port type, and port number, which are part of both the configuration commands and the configuration files. Configuration files are managed only from the device Stack Master, including:

24 Introduction

NOTE: Two stacking member are considered the same age if they were inserted within a

ten minute interval.

Page 25

• Saving to the FLASH

• Uploading Configuration files to an external TFTP Server

• Downloading Configuration files from an external TFTP Server

NOTE: Stack configuration for all configured ports is saved, even if the stack is reset and/or the

ports are no longer present.

Whenever a reboot occurs, topology discovery is performed, and the Master learns all units in the stack. Unit IDs are saved in the unit and are learned through topology discovery. If a unit attempts to boot without a selected Master, and the unit is not operating in stand-alone mode, the unit does not boot.

Configuration files are changed only through explicit user configuration. Configuration files are not automatically modified when:

• Units are Added

• Units are Removed

• Units are reassigned Unit IDs

• Units toggle between Stacking Mode and Stand-alone Mode

Each time the system reboots, the Startup Configuration file in the Master unit is used to configure the stack.

If a stack member is removed from the stack, and then replaced with a unit with the same Unit ID, the stack member is configured with the original device configuration. Only ports which are physically present are displayed in the PowerConnect OpenManage Switch Administrator home page, and can be configured through the web management system. Non-present ports are configured through the CLI or SNMP interfaces.

Exchanging Stacking Members

If a stack member with the same Unit ID replaces an existing Unit ID with the same Unit ID, the previous device configuration is applied to the inserted stack member. If the new inserted device has either more or fewer ports than the previous device, the relevant port configuration is applied to the new stack member. For example,

• If a PowerConnect 3424/P replaces PowerConnect 3424/P, all port configurations remain the same.

• If a PowerConnect 3448/P replaces the PowerConnect 3448/P, all port configurations remain the same.

Switching from the Stack Master to the Backup Stack Master

The Backup Master replaces the Stack Master if the following events occur:

• The Stack Master fails or is removed from the stack.

• Links from the Stack Master to the stacking members fails.

• A soft switchover is performed with either via web interface or the CLI.

Switching between the Stack Master and the Backup Master results in a limited service loss. Any dynamic tables are relearned if a failure occurs. The running configuration file is synchronized between Stack Master and the Backup Master, and continues running on the Backup Master.

Features Overview

This section describes the device features. For a complete list of all updated device features, see the latest software version

Power over Ethernet

Power over Ethernet (PoE) provides power to devices over existing LAN cabling, without updating or modifying the network infrastructure. PoE removes the need for placing network devices next to power sources. PoE can be used in the following applications:

• IP Phones

• Wireless Access Points

www.dell.com | support.dell.com

• IP Gateways

•PDAs

• Audio and video remote monitoring

For more information about Power over Ethernet, see "Managing Power over Ethernet".

Head of Line Blocking

Head of Line (HOL) blocking results in traffic delays and frame loss caused by traffic competing for the same egress port resources. HOL blocking queues packets, and the packets at the head of the queue are forwarded before packets at the end of the queue.

Flow Control Support (IEEE 802.3X)

Flow control enables lower speed devices to communicate with higher speed devices, by requesting that the higher speed device refrains from sending packets. Transmissions are temporarily halted to prevent buffer overflows.

For information on configuring Flow Control for ports or LAGs, see "Defining Port Configuration" or "Defining LAG Parameters."

Release Notes

Back Pressure Support

On half-duplex links, the receiving port prevents buffer overflows by occupying the link so that it is unavailable for additional traffic.

For information on configuring Flow Control for ports or LAGs, see "Defining Port Configuration" or "Defining LAG Parameters."

Virtual Cable Testing (VCT)

VCT detects and reports copper link cabling occurrences such as open cables and cable shorts. For more information on testing cables, see "Running Cable Diagnostics".

28 Introduction

Page 29

MDI/MDIX Support

The device automatically detects whether the cable connected to an RJ-45 port is crossed or straight through, when auto-negotiation is enabled.

Standard wiring for end stations is hubs and switches is known as

For information on configuring MDI/MDIX for ports or LAGs, see "Defining Port Configuration" or "Defining LAG Parameters."

Media-Dependent Interface

Media-Dependent Interface with Crossover

(MDI) and the standard wiring for

(MDIX).

Auto Negotiation

Auto negotiation allows the device to advertise modes of operation. The auto negotiation function provides the means to exchange information between two devices that share a point-to-point link segment, and to automatically configure both devices to take maximum advantage of their transmission capabilities.

The PowerConnect 3400 series enhances auto negotiation by providing port advertisement. Port advertisement allows the system administrator to configure the port speeds that are advertised.

For more information on auto-negotiation, see "Defining Port Configuration" or "Defining LAG Parameters."

MAC Address Supported Features

MAC Address Capacity Support

The device supports up to 8K MAC addresses. The device reserves specific MAC addresses for system use.

Static MAC Entries

MAC entries can be manually entered in the Bridging Table, as an alternative to learning them from incoming frames. These user-defined entries are not subject to aging, and are preserved across resets and reboots.

For more information, see "Defining Static Addresses."

Self-Learning MAC Addresses

The device enables automatic MAC address learning from incoming packets. The MAC addresses are stored in the Bridging Table.

Automatic Aging for MAC Addresses

MAC addresses, from which no traffic is received for a given period, are aged out. This prevents the Bridging Table from overflowing.

For more information on configuring the MAC Address Age Out Time, see "Viewing Dynamic Addresses."

Introduction 29

Page 30

VLAN-aware MAC-based Switching

The device always performs VLAN-aware bridging. Classic bridging(IEEE802.1D) is not performed, where frames are forwarded based only on their destination MAC address. However, a similar functionality can be configured for untagged frames. Frames addressed to a destination MAC address that is not associated with any port are flooded to all ports of the relevant VLAN.

MAC Multicast Support

Multicast service is a limited broadcast service, which allows one-to-many and many-to-many connections for information distribution. Layer 2 Multicast service is where a single frame is addressed to a specific Multicast address, from where copies of the frame are transmitted to the relevant ports.

www.dell.com | support.dell.com

For more information, see "Assigning Multicast Forward All Parameters."

Layer 2 Features

IGMP Snooping

IGMP Snooping examines IGMP frame contents, when they are forwarded by the device from work stations to an upstream Multicast router. From the frame, the device identifies work stations configured for Multicast sessions, and which Multicast routers are sending Multicast frames.

For more information, see "IGMP Snooping."

Port Mirroring

Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from a monitored port to a monitoring port. Users specify which target port receives copies of all traffic passing through a specified source port.

For more information, see "Defining Port Mirroring Sessions."

Broadcast Storm Control

Storm Control enables limiting the amount of Multicast and Broadcast frames accepted and forwarded by the device.

When Layer 2 frames are forwarded, Broadcast and Multicast frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes connected on all ports.

For more information, see "Enabling Storm Control."

30 Introduction

Page 31

VLAN Supported Features

VLAN Support

VLANs are collections of switching ports that comprise a single broadcast domain. Packets are classified as belonging to a VLAN based on either the VLAN tag or based on a combination of the ingress port and packet contents. Packets sharing common attributes can be grouped in the same VLAN.

For more information, see "Configuring VLANs."

Port Based Virtual LANs (VLANs)

Port-based VLANs classify incoming packets to VLANs based on their ingress port.

For more information, see "Defining VLAN Ports Settings."

Full 802.1Q VLAN Tagging Compliance

IEEE 802.1Q defines an architecture for virtual bridged LANs, the services provided in VLANs, and the protocols and algorithms involved in the provision of these services.

GVRP Support

GARP VLAN Registration Protocol (GVRP) provides IEEE 802.1Q-compliant VLAN pruning and dynamic VLAN creation on 802.1Q trunk ports. When GVRP is enabled, the device registers and propagates VLAN membership on all ports that are part of the active underlying

Protocol Features"

topology.

For more information, see "Configuring GVRP Parameters."

"Spanning Tree

Private VLANs

Private VLAN ports, a Layer 2 security feature, provide isolation between ports within the same Broadcast domain.

For more information on Private VLANs, see "Configuring Private VLANs".

Spanning Tree Protocol Features

Spanning Tree Protocol (STP)

802.1d Spanning tree is a standard Layer 2 switch requirement that allows bridges to automatically prevent and resolve L2 forwarding loops. Switches exchange configuration messages using specifically formatted frames and selectively enable and disable forwarding on ports.

For more information, see "Configuring the Spanning Tree Protocol."

Introduction 31

Page 32

Fast Link

STP can take up to 30-60 seconds to converge. During this time, STP detects possible loops, allowing time for status changes to propagate and for relevant devices to respond. 30-60 seconds is considered too long of a response time for many applications. The Fast Link option bypasses this delay, and can be used in network topologies where forwarding loops do not occur.

For more information enabling Fast Link for ports and LAGs, see "Defining STP Port Settings"

Defining Static Addresses."

IEEE 802.1w Rapid Spanning Tree

Spanning Tree can take 30-60 seconds for each host to decide whether its ports are actively forwarding traffic. Rapid Spanning Tree (RSTP) detects uses of network topologies to enable faster

www.dell.com | support.dell.com

convergence, without creating forwarding loops.

For more information, see "Defining Rapid Spanning Tree."

IEEE 802.1s Multiple Spanning Tree

Multiple Spanning Tree (MSTP) operation maps VLANs into STP instances. MSTP provides differing load balancing scenario. Packets assigned to various VLANs are transmitted along different paths within MSTP Regions (MST Regions). Regions are one or more MSTP bridges by which frames can be transmitted. The standard lets administrators assign VLAN traffic to unique paths.

For more information, see "Configuring the Spanning Tree Protocol".

Link Aggregation

Up to eight Aggregated Links may be defined, each with up to eight member ports, to form a single Link Aggregated Group (LAG). This enables:

• Fault tolerance protection from physical link disruption

• Higher bandwidth connections

• Improved bandwidth granularity

• High bandwidth server connectivity

LAG is composed of ports with the same speed, set to full-duplex operation.

For more information, see "Defining LAG Parameters."

Link Aggregation and LACP

LACP uses peer exchanges across links to determine, on an ongoing basis, the aggregation capability of various links, and continuously provides the maximum level of aggregation capability achievable between a given pair of devices. LACP automatically determines, configures, binds, and monitors the port binding within the system.

For more information, see "Aggregating Ports."

32 Introduction

Page 33

BootP and DHCP Clients

DHCP enables additional setup parameters to be received from a network server upon system startup. DHCP service is an on-going process. DHCP is an extension to BootP.

For more information on DHCP, see "Defining DHCP IP Interface Parameters."

Quality of Service Features

Class Of Service 802.1p Support

The IEEE 802.1p signaling technique is an OSI Layer 2 standard for marking and prioritizing network traffic at the data link/MAC sub-layer. 802.1p traffic is classified and sent to the destination. No bandwidth reservations or limits are established or enforced. 802.1p is a spin-off of the 802.1Q (VLANs) standard. 802.1p establishes eight levels of priority, similar to the IP Precedence IP Header bit-field.

For more information, see "Configuring Quality of Service."

Device Management Features

SNMP Alarms and Trap Logs

The system logs events with severity codes and timestamps. Events are sent as SNMP traps to a Trap Recipient List.

For more information on SNMP Alarms and Traps, see "Defining SNMP Parameters

SNMP Versions 1, 2 and 3

Simple Network Management Protocol (SNMP) over the UDP/IP protocol controls access to the system, a list of community entries is defined, each of which consists of a community string and its access privileges. There are 3 levels of SNMP security read-only, read-write, and super. Only a super user can access the community table.

For more information, see "Defining SNMP Parameters".

Web Based Management

With the web based management, the system can be managed from any web browser. The system contains an Embedded Web Server (EWS), which serves HTML pages, through which the system can be monitored and configured. The system internally converts web-based input into configuration commands, MIB variable settings and other management-related settings.

Configuration File Download and Upload

The device configuration is stored in a configuration file. The Configuration file includes both system wide and port specific device configuration. The system can display configuration files in the form of a collection of CLI commands, which are stored and manipulated as text files.

For more information, see "Managing Files."

Introduction 33

Page 34

TFTP Trivial File Transfer Protocol

The device supports boot image, software, and configuration upload/download via TFTP.

Remote Monitoring

Remote Monitoring (RMON) is an extension to SNMP, which provides comprehensive network traffic

monitoring capabilities (as opposed to SNMP which allows network device management and monitoring). RMON is a standard MIB that defines current and historical MAC-layer statistics and control objects, allowing real-time information to be captured across the entire network.

For more information, see "Viewing Statistics."

Command Line Interface

www.dell.com | support.dell.com

Command Line Interface (CLI) syntax and semantics conform as much as possible to common industry practice. CLI is composed of mandatory and optional elements. The CLI interpreter provides command and keyword completion to assist user and shorten typing.

Syslog

Syslog is a protocol that enables event notifications to be sent to a set of remote servers, where they can be stored, examined and acted upon. The system sends notifications of significant events in real time, and keeps a record of these events for after-the-fact usage.

For more information on Syslog, see "Managing Logs."

SNTP

The Simple Network Time Protocol (SNTP) assures accurate network Ethernet Switch clock time synchronization up to the millisecond. Time synchronization is performed by a network SNTP server. Time sources are established by Stratums. Stratums define the distance from the reference clock. The higher the stratum (where zero is the highest), the more accurate the clock.

For more information, see "Configuring SNTP Settings."

Domain Name System

Domain Name System (DNS) converts user-defined domain names into IP addresses. Each time a domain name is assigned the DNS service translates the name into a numeric IP address. For example, www.ipexample.com is translated to 192.87.56.2. DNS servers maintain domain name databases and their corresponding IP addresses.

For more information, see "Configuring Domain Name Systems".

Traceroute

Traceroute discovers IP routes that packets were forwarded along during the forwarding process. The CLI Traceroute utility can be executed from either the user-exec or privileged modes.

34 Introduction

Page 35

Security Features

SSL

Secure Socket Layer (SSL) is an application-level protocol that enables secure transactions of data through privacy, authentication, and data integrity. It relies upon certificates and public and private keys.

Port Based Authentication (802.1x)

Port based authentication enables authenticating system users on a per-port basis via an external server. Only authenticated and approved system users can transmit and receive data. Ports are authenticated via the Remote Authentication Dial In User Service (RADIUS) server using the Extensible Authentication Protocol (EAP).

For more information, see "Configuring Port Based Authentication."

Locked Port Support

Locked Port increases network security by limiting access on a specific port only to users with specific MAC addresses. These addresses are either manually defined or learned on that port. When a frame is seen on a locked port, and the frame source MAC address is not tied to that port, the protection mechanism is invoked.

For more information, see "Configuring Port Security."

RADIUS Client

RADIUS is a client/server-based protocol. A RADIUS server maintains a user database, which contains per-user authentication information, such as user name, password and accounting information.

For more information, see "Configuring RADIUS Settings."

SSH

Secure Shell (SSH) is a protocol that provides a secure, remote connection to a device. SSH version 2 is currently supported. The SSH server feature enables an SSH client to establish a secure, encrypted connection with a device. This connection provides functionality that is similar to an inbound telnet connection. SSH uses RSA and DSA Public Key cryptography for device connections and authentication.

TAC ACS+

TACACS+ provides centralized security for validation of users accessing the device. TACACS+ provides a centralized user management system, while still retaining consistency with RADIUS and other authentication processes.

For more information, see "Defining TACACS+ Settings."

Introduction 35

Page 36

Password Management

Password management provides increased network security and improved password control. Passwords for SSH, Telnet, HTTP, HTTPS, and SNMP access are assigned security features. For more information on Password Management, see "Managing Passwords".

Additional CLI Documentation

The CLI Reference Guide, which is available on the Documentation CD, provides information about the CLI commands used to configure the device. The document provides information about the command description, syntax, default values, guidelines, and examples.

Stack ID Button

The device front panel contains a Stack ID button used to manually select the Unit ID for the Stack Master and members.

The Stack Master and members must be selected within 15 seconds of booting the device. If the Stack Master is not selected within 15 seconds, the device is booted in stand-alone mode. To select a Unit ID for the device, reboot the device.

The Stack Master receives the Unit ID of 1 or 2. If both Unit 1 and Unit 2 are present, the unit that is not elected functions as the Backup Master. Stack members receive a separate Unit ID (3-6). For example, if there are four units in a stack, the Master unit is either 1 or 2, the backup Master is either 1 or 2 depending on the Unit ID of the Master unit, the third member is 3, and the fourth Stack member is 4.

NOTE: The device does not automatically detect a stand-alone unit. If a Unit ID has already been

selected, press the Stack ID button several times until no stacking LED is lit.

Reset Button

The PowerConnect 3424/P and PowerConnect 3448/P switches have a reset button, located on the front panel, for manual reset of the device. If the Master device is reset, the entire stack is reset. If only a member unit is reset, the remain stacking members are not reset.

The single reset circuit of the switch is activated by power-up or low-voltage conditions.

Ventilation System

The PowerConnect 3424/P and PowerConnect 3448/P switches with the PoE feature have five built-in fans. The non-PoE PowerConnect 3424 and PowerConnect 3448 devices have two built-in fans. Operation can be verified by observing the LED that indicates if one or more fans is faulty.

Each PowerConnect 3400 series stack contains a single Master unit, and may have a Master Backup unit, while the remaining units are considered stacking Members.

54 Installing the PowerConnect 3424/P and PowerConnect 3448/P

Page 55

PowerConnect 3400 series switches use the RJ-45 Gigabit Ethernet ports (G3 and G4) for stacking. This enables added stacking capabilities to the devices without adding additional device accessories. To stack the devices together, insert a standard Category 5 cable into port G3 in the uppermost device in the stack, and into port G4 of the device immediately below it in the stack. Repeat this process until all devices are connected. Connect the bottommost device’s port G3 in the stack to port G4 of the uppermost device in the stack.

Figure 3-5. Stacking Cable Diagram

NOTE: In stacking mode ports designated as G3 and G4 are not displayed in the EWS. The effect is of not

being present on the device. This is because the ports receive a different index for stacking.

Stack unit identification is performed on the device front panel using the Stack ID button.

Installing the PowerConnect 3424/P and PowerConnect 3448/P 55

Page 56

Figure 3-6. Stacking Configuration and Identification Panel

www.dell.com | support.dell.com

Each stack device has a unique identifying unit ID that defines the unit’s position and function in the stack. If the device is a stand-alone unit, the Stack LED is not illuminated. The default setting is stand-alone.

The unit ID is manually configured by using the Stack ID button. The unit ID is indicated by the Stack ID LEDs. Unit ID 1 and 2 are reserved for the Master and Backup Master unit, and unit ID 3 to 6 are for Member units.

Unit ID Selection Process

The unit ID selection process is as follows:

Ensure that the stand-alone/Master device Console port is connected to a VT100 terminal device or VT100 terminal emulator via the RS-232 crossover cable.

Locate an AC power receptacle.

Deactivate the AC power receptacle.

Connect the device to the AC receptacle.

Activate the AC power receptacle.

When powering up, the configured LED number (corresponding to the previously saved unit ID) begins to flash. The LED flashes for 15 seconds. During this period, select a specific Stack ID by pressing the Stack ID button until the appropriate Stack ID LED is illuminated.

Stacking LEDs

Stack ID Button

56 Installing the PowerConnect 3424/P and PowerConnect 3448/P

Selection Process

— To advance the stacking ID LED number, continue pressing the Stack ID button. When LED 6 is flashing, pressing the Stack ID button results in the device being configured as a stand-alone. Pressing the Stack ID button again advances the Stack ID to 1. Unit 1 and Unit 2 are master-enabled units. See "Stacking Overview" master-election process.

End selection process

— The unit ID selection process is completed when the 15-second flashing period has transpired. The Stack ID button becomes unresponsive and the unit ID is set to the LED ID flashing at the end of the period.

NOTE: These steps should be performed one unit at a time until all stack members are powered up and

their Stack IDs are selected. Performing the steps one unit at a time will allow for sufficient time to select the Stack ID for each unit. However, the entire stack should be cabled as per the "Stacking Cable Diagram" before powering up the devices.

Booting the Switch

When the power is turned on with the local terminal already connected, the switch goes through power-on self-test (POST). POST runs every time the device is initialized and checks hardware components to determine if the device is fully operational before completely booting. If a critical problem is detected, the program flow stops. If POST passes successfully, a valid executable image is loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure.

The boot process runs approximately 30 seconds.

Advanced Configuration

This section provides information about dynamic allocation of IP addresses and security management based on the Authentication, Authorization, and Accounting (AAA) mechanism, and includes the following topics:

• Configuring IP Addresses through DHCP

• Configuring IP Addresses through BOOTP

• Security Management and Password Configuration

When configuring/receiving IP addresses through DHCP and BOOTP, the configuration received from these servers includes the IP address and may include subnet mask and default gateway.

Retrieving an IP Address From a DHCP Server

When using the DHCP protocol to retrieve an IP address, the device acts as a DHCP client. When the device is reset, the DHCP command is saved in the configuration file, but the IP address is not. To retrieve an IP address from a DHCP server, perform the following steps:

Select and connect any port to a DHCP server or to a subnet that has a DHCP server on it, in order to retrieve the IP address.

Enter the following commands to use the selected port for receiving the IP address. In the following example, the commands are based on the port type used for configuration.

• Assigning Dynamic IP Addresses:

console# configure

console(config)# interface ethernet 1/e1

console(config-if)# ip address dhcp hostname powerconnect

console(config-if)# exit

console(config)#

• Assigning Dynamic IP Addresses (on a VLAN):

console# configure

console(config)# interface ethernet vlan 1

console(config-if)# ip address dhcp hostname device

console(config-if)# exit

console(config)#

Configuring PowerConnect 3424/P and 3448/P 65

The interface receives the IP address automatically.

To verify the IP address, enter the in the following example.

console# show ip interface

IP Address I/F Type

------------- ------ -------

100.1.1.1/24 vlan 1 dynamic

www.dell.com | support.dell.com

NOTE: It is not necessary to delete the device configuration to retrieve an IP address for the

DHCP server.

NOTE: When copying configuration files, avoid using a configuration file that contains an instruction to

enable DHCP on an interface that connects to the same DHCP server, or to one with an identical configuration. In this instance, the device retrieves the new configuration file and boots from it. The device then enables DHCP as instructed in the new configuration file, and the DHCP instructs it to reload the same file again.

NOTE: If you configure a DHCP IP address, this address is dynamically retrieved, and the ip address

dhcp command is saved in the configuration file. In the event of master failure, the backup will again

attempt to retrieve a DHCP address. This could result in one of the following:

• The same IP address may be assigned.

• A different IP address may be assigned, which could result in loss of connectivity to the

management station.

• The DHCP server may be down, which would result in IP address retrieval failure, and possible loss of connectivity to the management station.

show ip interface

command at the system prompt as shown

Receiving an IP Address From a BOOTP Server

The standard BOOTP protocol is supported and enables the device to automatically download its IP host configuration from any standard BOOTP server in the network. In this case, the device acts as a BOOTP client.

To retrieve an IP address from a BOOTP server:

Select and connect any port to a BOOTP server or subnet containing such a server, to retrieve the IP address.

At the system prompt, enter the Configuration from flash.

The device reboots with no configuration and in 60 seconds starts sending BOOTP requests. The device receives the IP address automatically.

Page 67

NOTE: When the device reboot begins, any input at the ASCII terminal or keyboard automatically

cancels the BOOTP process before completion and the device does not recieve an IP address from the BOOTP server.

The following example illustrates the process:

console> enable

console# delete startup-config

console# reload

To verify the IP address, enter the

show ip interface

command.

The device is now configured with an IP address.

Security Management and Password Configuration

System security is handled through the Authentication, Authorization, and Accounting (AAA) mechanism that manages user access rights, privileges, and management methods. AAA uses both local and remote user databases. Data encryption is handled through the SSH mechanism.

The system is delivered with no default password configured; all passwords are user-defined. If a user-defined password is lost, a password recovery procedure can be invoked from the menu. The procedure is applicable for the local terminal only and allows a one-time access to the device from the local terminal with no password entered.

Configuring Security Passwords

The security passwords can be configured for the following services:

• Terminal

• Telnet

• SSH

•HTTP

•HTTPS

NOTE: Passwords are user-defined.

Startup

Configuring PowerConnect 3424/P and 3448/P 67

Page 68

NOTE: When creating a user name, the default priority is 1, which allows access but not configuration

rights. A priority of 15 must be set to enable access and configuration rights to the device. Although user names can be assigned privilege level 15 without a password, it is recommended to always assign a password. If there is no specified password, privileged users can access the Web interface with any password.

NOTE: Passwords can be secured by using password management commands to force aging-out of

passwords, or expiration of passwords. For more information, see "Security Management and Password Configuration".

Port Default Settings

The general information for configuring the device ports includes the short description of the auto-negotiation mechanism and the default settings for switching ports.

Auto-Negotiation

Auto-negotiation enables automatic detection of speed, duplex mode and flow control on all switching 10/100/1000BaseT ports. Auto-negotiation is enabled per port by default.

Auto-negotiation is a mechanism established between two link partners to enable a port to advertise its transmission rate, duplex mode and flow control (the flow control default is disabled) abilities to its partner. The ports then both operate at the highest common denominator between them.

www.dell.com | support.dell.com

If connecting a NIC that does not support auto-negotiation or is not set to auto-negotiation, both the device switching port and the NIC must be manually set to the same speed and duplex mode.

If the station on the other side of the link attempts to auto-negotiate with a device 100BaseT port that is configured to full duplex, the auto-negotiation results in the station attempting to operate in half duplex.

MDI/MDIX

The device supports auto-detection of straight through and crossed cables on all switching 10/100/1000BaseT ports. The feature is part of the Auto-negotiation and is enabled when Auto-negotiation is enabled.

When the MDI/MDIX (Media Dependent Interface with Crossover) is enabled, the automatic correction of errors in cable selection is possible, thus making the distinction between a straight through cable and a crossover cable irrelevant. (The standard wiring for end stations is known as MDI (Media Dependent Interface), and the standard wiring for hubs and switches is known as MDIX.

Flow Control

The device supports 802.3x Flow Control for ports configured with the Full Duplex mode. By default, this feature is disabled. It can be enabled per port. The flow control mechanism allows the receiving side to signal to the transmitting side that transmission must temporarily be halted to prevent buffer overflow.

Back Pressure

The device supports back pressure for ports configured with the half duplex mode. By default, this feature is disabled. It can be enabled per port. The back-pressure mechanism prevents the sender from transmitting additional traffic temporarily. The receiver may occupy a link so it becomes unavailable for additional traffic.
