Starting a Cisco MDS 9020 Fabric Switch

The following procedure is a review of the tasks you should have completed during hardware
installation, including starting up the switch. These tasks must be completed before you can configure
the switch.

Before you can configure a switch, follow these steps:

Step 1 Verify the following physical connections for the new Cisco MDS 9020 Fabric Switch:

• The console port is physically connected to a computer terminal (or terminal server).

• The management 10/100 Ethernet port (mgmt0) is connected to an external hub, switch, or router.

Refer to the Cisco MDS 9020 Fabric Switch Hardware Installation Guide for more information.

Tip Save the host ID information for future use (for example, to enable licensed features). The host

ID information is provided in the Proof of Purchase document that accompanies the switch.

Step 2 Verify that the default console port parameters are identical to those of the computer terminal (or

terminal server) attached to the switch console port:

• 9600 baud

• 8 data bits

• 1 stop bit

• No parity

Step 3 Power on the switch. The switch boots automatically and the switch# prompt appears in your terminal

window.

Initial Setup Routine

The first time that you access a Cisco MDS 9020 Fabric Switch, it runs a setup program that prompts
you for the IPaddressandotherconfigurationinformation necessary for the switch to communicate over
the Ethernet interface. This information is required to configure and manage the switch.

Note The IP address can be configured from the CLI only. When you power up the switch for the first time,

assign the IP address. After you perform this step, the Cisco Fabric Manager can reach the switch
through the Ethernet port.

Preparing to Configure the Switch

Before you configure a Cisco MDS 9020 Fabric Switch for the first time, you need the following
information:

• Administrator password, including:

–

Creating a password for the administrator (required).

–

Creating an additional login account and password (optional).

• IP address for the switch management interface. The management interface is an out-of-band

Ethernet interface.

• Subnet mask for the switch's management interface (optional).

• IP addresses, including:

–

Destination prefix, destination prefix subnet mask, and next hop IP address, if you want to
enable IP routing. Also, provide the IP address of the default network (optional).

–

Otherwise, provide an IP address of the default gateway (optional).

• SSH service on the switch—Toenable this optional service, select the SSH key (rsa) and the number

of key bits (768 to 2048).

• Default domain name (optional).

• NTP server IP address (optional).

• SNMP community string (optional).

• Switch name—This is your switch prompt (optional).

Note Be sure to configure the IP route, the IP default network address, and the IP default gateway address to

Default Login

enable SNMP access. If IP routing is enabled, the switch uses the IP route and the default network IP
address. If IP routing is disabled, the switch uses the default gateway IP address.

The Cisco MDS 9020 Fabric Switch has the network administrator as a default user (admin). Youcannot
change the default user at any time. (See the “Role-Based Authorization” section on page 9-5.)

You must explicitly configure a strong password for the Cisco MDS 9020 Fabric Switch. If a password
is trivial (short, easy-to-decipher), your password configurationis rejected. Be sure to configure a strong
password. (See “Configuring User Accounts” section on page 9-6.) If you configure and subsequently
forget this new password, you have the option to recover this password. (See the “Recovering the

Administrator Password” section on page 9-10.)

Setup Options

The setup scenario differs based on the subnet to which you are adding the new switch. You must
configurea Cisco MDS 9020 Fabric Switch with an IP address to enable management connections from
outside of the switch. Figure 3-1 shows a switch that is managed out-of-band over a connection to the
network through an Ethernet port.

Assigning Setup Information

This section describes how to initially configure the switch for both out-of-band and in-band
management.

Note Press Ctrl-C at any prompt to skip the remaining configuration options and proceed with what is

configureduntil that point. Entering the new password for the administrator is a requirement and cannot
be skipped.

Tip If you do not wish to answer a previously configured question, or if you wish to skip answers to any

questions, press Enter. If a default answer is not available (for example, switch name), the switch uses
previously configured value and skips to the next question.

Configuring Out-of-Band Management

To configure the switch for first time out-of-band access, follow these steps:

Step 1 Power on the switch. The Cisco MDS 9020 Fabric Switch boots automatically.
Step 2 Enter the password for the administrator.

Enter the password for admin: admin123

Step 3 Enter yes to enter the setup mode.

---- Basic System Configuration Dialog ---­This setup utility will guide you through the basic configuration of
the system. Setup configures only enough connectivity for management
of the system.

*Note: setup is mainly used for configuring the system initially,
when no configuration is present. So setup always assumes system
defaults and not the current system configuration values.

Press Enter if you want to skip any dialog. Use ctrl-c at anytime
to skip all remaining dialogs.

Would you like to enter the basic configuration dialog (yes/no): yes

The setup utility guides you through the basic configuration process. Press Ctrl-C at any prompt to end
the configuration process.
