

Configuration Overview



This section describes the initial device configuration and includes:

lInitial Device Bootup

lPreliminary Configuration Requirements

lConfiguring Stacking



After all the device external connections are in place, a terminal must be connected to the device to monitor the boot and other procedures. The order of

installation and configuration procedures are illustrated in the following flowchart:



Instructions for setting up the device and hardware are provided in the preceding sections. For a first-time installation, the standard device installation is

performed. There are other special functions which can be performed, but this suspends the installation process and results in a system reboot. This option is

described later in this section.

General Configuration Information



Dell™PowerConnect™3324/3348isprovidedwithpre-defined implemented features and setup configuration.



Auto-Negotiation



Auto-negotiation allows a device to advertise modes of operation and share information with another device that shares a point-to-point link segment. This

automatically configures both devices to take maximum advantage of their abilities.



Auto-negotiation is performed completely within the physical layers during link initiation, without any additional overhead to either the MAC or higher protocol

layers. Auto-negotiation allows the ports to do the following:

lAdvertise their abilities.

lAcknowledge receipt and understanding of the common modes of operation that both devices share.

lReject the use of operational modes that are not shared by both devices.

lConfigure each port for the highest-level operational mode that both ports can support.



If connecting a port of the switch to the network interface controller (NIC) of a workstation or server that does not support auto-negotiation or is not set to

auto-negotiation, both the switching port and the NIC must be manually set with the Web browser interface or CLI commands to the same speed and duplex

mode.



Switching Port Default Settings



The following table describes the Port default settings.

Port Default Settings 

The following is an example for changing the port speed on port 1/e5 using CLI commands:



console> enable



console# configure



Console (config)# interface ethernet 1/e5



Console (config-if)# speed 100



The following is an example for enabling flow control on port 1/e5 using CLI commands:



NOTICE: If the station on the other side of the link attempts to auto-negotiate with a port that is manually configured to full duplex, the auto-

negotiation results in the station attempting to operate in half duplex. The resulting mismatch may lead to significant frame loss. This is inherent in the

auto-negotiation standard.

l2400

l4800

l9600

l19,200

l38,400

l57,600

l115,200



console# configure



console(config)# line console



console(config-line)# speed 9600



NOTE: The default baud rate is 9600.

NOTE: Closing the device does not return the default baud rate. It must be specifically configured.

NOTE: In order to enter configuration mode, you must specify administrative level 15 privileges.

console(config-if)# exit



console(config)# exit



Terminal Connection Configuration



The PowerConnect 3324/3348 requires the following Terminal Connection parameters for configuration:

lno parity

lone stop bit

l8 data bits



Other Configuration Requirements



The following is required for downloading embedded software and configuring the device:

lASCII terminal (or emulation) connected to the Serial port in the back of the unit.

lAssigned IP address for PowerConnect 3324/3348 for device remote control using with Telnet, SSH, etc.



Booting the Device



When power is turned on with the local terminal already connected, a device goes through POST (Power On Self Test). This built-in power-on test runs every

time the device is initialized. The POST checks hardware components to determine if the device is fully operational before completing boot up.



If a critical problem is detected, the program flow stops. If POST passes successfully, the code is decompressed into the RAM memory.



The POST messages are displayed on the terminal and indicate test success or failure.



To boot the device:

1. Ensure the ASCII cable is connected to the terminal.

2. Connect the power supply to the device; the device begins booting up. The boot-up test first counts the device memory availability and then continues

to boot-up. The following screen is an example of the displayed POST test:



The auto-boot message that appears at the end of the POST (see the last lines) indicates that no problems were encountered during boot.



At this point, a user input can be entered to get the Startup menu if it is necessary to run special procedures that can be invoked from this menu. To enter the

Startup menu, the <Esc> or <Enter> keys must be pressed within the first two seconds after the auto-boot message appears. For details regarding the

Startup menu, see Startup Menu Functions.



If no user input is entered, the system continues operation by decompressing the code into RAM. The code starts running from RAM and the list of available

port numbers and their states (up or down) are displayed.

After the device has been booted successfully, the system prompt appears (console>) and the configuration process can be started. The local terminal can be

used for configuration.



Device Configuration Introduction



There are two types or levels of configuration. The initial configuration describes basic configuration functions with basic security considerations. The advanced

configuration includes dynamic IP configuration and more advanced security considerations.



console> enable



console# copy running-config startup-config



Initial Configuration



Initial configuration starts after the device has booted successfully. The initial configuration scope for the device includes:

lStatic IP address and Subnet Mask

lDefault gateway

lUser name and privilege level must be configured to allow remote management.



If the device is to be managed from an SNMP-based management station, SNMP community strings must also be configured.



Static IP Address and Subnet Mask



In PowerConnect 3324/3348 devices, IP interfaces can be configured on each port and no limitation on the number of IP interfaces is imposed. After entering

the configuration command, it is recommended to check if a port was configured with the IP address by entering the "show ip interface" command.



To configure an interface on a VLAN, enter the commands at the system prompt as shown in the following configuration example:



console> enable



console# configure



console(config)# interface vlan 1



console(config-if)# ip address 100.1.1.1 /8



console(config-if)# exit



console(config)# exit

NOTICE: After making any configuration changes, the new configuration must be saved before rebooting. To save the configuration, enter:

NOTICE: Only one VLAN can be assigned an IP address. If you assign an address to any other VLAN, the new address overrides the original IP

address.

To configure an interface on a port, enter the commands at the system prompt as shown in the following configuration example:



console> enable



console# configure



console(config)# interface ethernet 1/e1



console(config-if)# ip address 10.1.1.1 255.0.0.0



Default Gateway



To manage a PowerConnect 3324/3348 device from a remote network, a default gateway, which is the gateway that a device uses if a specific gateway is not

specified, must be configured. The configured gateway IP address must belong to the same subnet as one of the device IP interfaces.



To configure a default gateway, enter the command at the system prompt as shown in this configuration example:



console> enable



console# configure



console(config)# ip default-gateway 100.1.1.100



console(config)# exit



User Name, Password, and Privilege Level



IMPORTANT: To manage a device from a remote terminal or Web Management Interface, a user name, a password, and the highest privilege level (15)

must be entered. (The highest level provides access to the CLI configure context.) For details about the privilege level, see the CLI Reference Guide.



The configured user name is entered as a login name for remote management sessions. To configure user name and privilege level, enter the command at the

system prompt as shown in the configuration example:



console> enable



console# configure



console(config)# username admin password admin level 15



console(config)# exit
