Configuring the Switch with the CLI-Based Setup Program

Configuring the Switch with the CLI-Based Setup Program

Accessing the CLI Through Express Setup

You can access the CLI on an unconfigured switch. Set the switch in Express Setup mode and connect a switch Ethernet port to an Ethernet port on your PC or workstation. Follow the steps described in the getting started guide for turning on the switch and using Express Setup.

When the switch is in Express Setup mode, open a Telnet session to the switch by entering the IP address 10.0.0.1. Enter the setup user EXEC command. Enter the information described in IP Settings and Completing the Setup Program.

After you have entered the configuration information for the switch, save it to flash memory by using the write memory privileged EXEC command.


Note


In Express Setup mode, the IP address 10.0.0.1 remains active on the switch until you enter the write memory command. You lose the Telnet connection after entering the write memory command.


Accessing the CLI Through the Console Port

You can access the CLI on a configured or unconfigured switch by connecting the RJ-45 console port or USB console port of the switch to your PC or workstation and accessing the switch through a terminal emulation program.


Note


If you have stacked your switches, connect to the console port of one of the switches in the stack. You can initially configure the entire stack from any member switch.


Connecting the RJ-45 Console Port

Procedure
    Step 1   Connect the RJ-45-to-DB-9 adapter cable to the 9-pin serial port on the PC. Connect the other end of the cable to the switch console port.
    Step 2   Start the terminal-emulation program on the PC or the terminal. The program, frequently a PC application such as HyperTerminal or ProcommPlus, makes communication between the switch and your PC or terminal possible.
    Step 3   Configure the baud rate and character format of the PC or terminal to match the console port default characteristics:
    • 9600 baud
    • 8 data bits
    • 1 stop bit
    • No parity
    • None (flow control)
    Step 4   Power on the switch as described in the switch getting started guide.
    Step 5   The PC or terminal displays the bootloader sequence. Press Enter to display the setup prompt. Follow the steps in Entering the Initial Configuration Information.

                    On a command switch, the host name is limited to 28 characters; on a member switch the name is limited to 31 characters. Do not use -n, where n is a number, as the last character in a host name for any switch.

                    
                    Enter host name [Switch]: host_name
                    
                    
                    Step 3   Enter an enable secret password, and press Return.

                    The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows spaces, but ignores leading spaces. The secret password is encrypted, and the enable password is in plain text.

                    
                    Enter enable secret: secret_password
                    
                    
                    Step 4   Enter an enable password, and press Return.
                    
                    Enter enable password: enable_password
                    
                    
                    Step 5   Enter a virtual terminal (Telnet) password, and press Return.

                    The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces.

                    
                    Enter virtual terminal password: terminal-password
                    
                    
                    Step 6   To configure the country code, enter yes and press Return.
                    
                    Do you want to configure country code? [no]: yes
                    
                    
                    Step 7   Enter the country code, and press Return.
                    
                    Enter the country code[US]:US
                    
                    
                    Step 8   (Optional) Configure Simple Network Management Protocol (SNMP) by responding to the prompts. You can also configure SNMP later through the CLI, Device Manager, or the Network Assistant application. To configure SNMP later, enter no.
                    
                    Configure SNMP Network Management? [no]: no
                    
                    
                    Step 9   Enter the interface name (physical interface or VLAN name) of the connection to the management network, and press Return. For this release, always use vlan1 as that interface.
                    
                    Enter interface name used to connect to the
                    management network from the above interface summary: vlan1
                    
                    
                    Step 10   Configure the interface by entering the switch IP address and subnet mask and pressing Return. The IP address and subnet masks shown are examples.
                    
                    Configuring interface vlan1:
                    Configure IP on this interface? [yes]: yes
                    IP address for this interface: 10.4.120.106
                    Subnet mask for this interface [255.0.0.0]: 255.0.0.0
                    
                    
                    Step 11   Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member switch or as a standalone switch.

                    If you enter N, the switch appears as a candidate switch in the Network Assistant GUI. You can configure the switch as a command switch later through the CLI, Device Manager, or the Network Assistant application. To configure it later, enter no.

                    
                    Would you like to enable as a cluster command switch? [yes/no]: no
                    
                    

                    You have now completed the initial configuration of the switch. This is an example of the configuration output that appears:

                    
                    The following configuration command script was created:
