Cisco Switch Setup Wizard Execution
If you unpack your switch and plug it in, you will be running the generic factory configuration, the setup wizard. This configuration is enough to allow you to use the switch on the default VLAN — vlan 1 — and will have all auto options enabled for each port.
There will not be a management interface for Telnet or SSH; but once a management IP is configured, you can connect with Telnet and the web browser to make configuration changes. The complete configuration is shown here:
Switch1>enable Switch1#show running-config Building configuration... Current configuration : 723 bytes ! version 12.1 no service pad service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Switch ! ! ip subnet-zero ! ! spanning-tree mode pvst no spanning-tree optimize bpdu transmission spanning-tree extend system-id ! ! interface FastEthernet0/1 ! interface FastEthernet0/2 ! (Omitted for brevity) ! interface FastEthernet0/11 ! interface FastEthernet0/12 ! interface Vlan1 no ip address no ip route-cache shutdown ! ip http server ! line con 0 line vty 5 15 ! ! end
When you first unpack a new switch or if you have erased the configuration, when the switch boots for the first time, it will automatically enter setup. If your switch does not, you have the option of running setup from Privileged EXEC mode. Here is the basic setup process; within just a few minutes, you can have the management interface on your switch up and running:
Switch>enable Switch#setup --- System Configuration Dialog --- Continue with configuration dialog? [yes/no]: yes At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets ''. Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system Would you like to enter basic management setup? [yes/no]: yes Configuring global parameters: Enter host name [Switch]: Switch1 The enable secret is a password used to protect access to privileged EXEC and configuration modes. This password, after entered, becomes encrypted in the configuration. Enter enable secret: secretpass The enable password is used when you do not specify an enable secret password, with some older software versions, and some boot images. Enter enable password: enablepass % Please choose a password that is different from the enable secret Enter enable password: enable The virtual terminal password is used to protect access to the switch over a network interface. Enter virtual terminal password: termpass Configure SNMP Network Management? [no]: Current interface summary Interface IP-Address OK? Method Status Protocol Vlan1 unassigned YES unset administratively down down FastEthernet0/1 unassigned YES unset up up FastEthernet0/2 unassigned YES unset up up FastEthernet0/3 unassigned YES unset up up FastEthernet0/4 unassigned YES unset down down FastEthernet0/5 unassigned YES unset down down FastEthernet0/6 unassigned YES unset down down FastEthernet0/7 unassigned YES unset down down FastEthernet0/8 unassigned YES unset up up FastEthernet0/9 unassigned YES unset up up FastEthernet0/10 unassigned YES unset up up FastEthernet0/11 unassigned YES unset up up FastEthernet0/12 unassigned YES unset up up Enter interface name used to connect to the management network from the above interface summary: vlan1 Configuring interface Vlan1: Configure IP on this interface? [no]: yes IP address for this interface: 192.168.1.241 Subnet mask for this interface [255.255.255.0] : Class C network is 192.168.1.0, 24 subnet bits; mask is /24 Would you like to enable as a cluster command switch? [yes/no]: no The following configuration command script was created: hostname Switch1 enable secret 5 $1$HXb6$RZPOXPyDvYuOWOhvYUP1d. enable password enablepass line vty 0 15 password termpass no snmp-server ! ! interface Vlan1 no shutdown ip address 192.168.1.241 255.255.255.0 ! interface FastEthernet0/1 ! interface FastEthernet0/2 ! (Omitted for brevity) ! interface FastEthernet0/11 ! interface FastEthernet0/12 ! end  Go to the IOS command prompt without saving this config.  Return back to the setup without saving this config.  Save this configuration to nvram and exit. Enter your selection:  Building configuration... [OK] Use the enabled mode 'configure' command to modify this configuration. Switch1# 00:09:12: %LINK-3-UPDOWN: Interface Vlan1, changed state to up 00:09:13: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up (Omitted for brevity) Switch1#
Notice how little information you need to enter to get basic management access to your switch over the network. This includes Telnet access to switch.
After the setup wizard is complete, enter Configuration mode to update your configuration to disable Telnet in favor of SSH (as a secure option) and configure your other network interfaces.
