Basic Software Configuration

You must enter privileged mode to perform most of the tasks described in this publication. Enter the enable command to enter privileged mode.

To connect to the switch via the console port and enter privileged mode, perform these steps:

Task	Command
Step 1 Make sure the terminal connected to the console port is configured as follows: 9600 baud, 8 data bits, no parity, 1 stop bit.	-
Step 2 Power up the switch. Output from the bootup script appears on the terminal screen.	-
Step 3 At the Enter Password prompt, press Return.	-
Step 4 Enter privileged mode.	enable
Step 5 At the Enter Password prompt, press Return.	-

This example shows how to assign an IP address and default gateway to the switch, verify the configuration, and check connectivity to a remote host:

Console> (enable) set interface sc0 10.1.1.50/255.0.0.0
Interface sc0 IP address and netmask set.
Console> (enable) set interface sc0 100
Interface sc0 vlan set.
Console> (enable) set ip route default 10.1.1.1
Route added.
Console> (enable) show interface

Console> (enable) ping 10.1.1.100
10.1.1.100 is alive
Console> (enable)

To set the port configuration on Ethernet ports, perform these steps in privileged mode:

Task	Command
Step 1 On 10/100-Mbps Fast Ethernet ports, set the port speed. Use the auto keyword to configure the port to autonegotiate both port speed and duplex mode with the connected port.	set port speed mod_num/port_num {10 | 100 | auto}
Step 2 On Ethernet or Fast Ethernet ports, set the port duplex mode. Use the auto keyword to configure the port to autonegotiate duplex mode1.	set port duplex mod_num/port_num {full | half | auto}
Step 3 Enable the port, if necessary.	set port enable mod_num/port_num
Step 4 Set the port name, if desired.	set port name mod_num/port_num name_string
Step 5 Verify the port configuration.	show port mod_num/port_num

1On 10/100-Mbps Fast Ethernet ports, you cannot change the duplex mode manually if the port speed is set to auto.

This example shows how to configure a 10/100-Mbps Fast Ethernet port to autonegotiate speed and duplex, set the port name, and verify the port configuration:

Console> (enable) set port speed 2/12 auto
Port 2/12 speed set to auto detect.
Console> (enable) set port name 2/12 NT Server 12
Port 2/12 name set.
Console> (enable) show port 2/12
Port  Name               Status     Vlan       Level  Duplex Speed Type
----- ------------------ ---------- ---------- ------ ------ ----- ------------
 2/12 NT Server 12       connect    1          normal a-half a-100 10/100BaseTX

To configure the global system settings, perform these steps in privileged mode:

Task	Command
Step 1 Set the system name.	set system name name_string
Step 2 Set the current date and time.	set time mm/dd/yy hh:mm:ss
Step 3 Set the system prompt. (By default, if the system name is set, it is used as the prompt. Use this command to override the default name.)	set prompt prompt_string
Step 4 Set the console password (used to access the switch CLI).	set password
Step 5 Set the enable password (used to access privileged configuration mode).	set enablepass

This example shows how to configure the global system settings:

Console> (enable) set system name Catalyst 6000
System name set.
Catalyst 6000> (enable) set time 08/18/98 10:08:00
Sat Apr 18 1998, 10:08:00
Catalyst 6000> (enable) set password
Enter old password:
Enter new password:
Retype new password:

Catalyst 6000> (enable) set enablepass
Enter old password:
Enter new password:
Retype new password:
Password changed.
