    Type in some of the following commands to get a basic config on the switch:

    Switch Config
    -------------

    [Basic]
    -------
    enable
    conf t
    hostname
    [Configure Virtual Interface]
    int vlan 1
    ip address 192.168.1.254 255.255.255.0
    no shut
    exit
    [Configure Default Gateway]
    ip default-gateway 192.168.1.1
    end
    sh int vlan 1
    wr
    sh run

    [Security]
    ----------
    [protect privilege mode]
    conf t
    enable secret XXXXXXX
    no enable password
    service password-encryption

    [Protect Console Port Access]
    line con 0
    password XXXXXXX
    login

    [Protect Line VTY Access]
    line vty 0 4
    password XXXXXXX
    login

    [Login Banners]
    conf t
    banner motd @
    **********************************
    Unauthorized Access is Prohibited
    **********************************

    @
    end

    [Enable SSH]
    conf t
    username YYYYYY password XXXXXX
    ip domain-name xyz.co.uk
    crypto key generate rsa
    <1024>
    ip ssh version 2
    line vty 0 4
    tranport input ssh
    end

    [General Commands]
    [sh ip int brief]
    terminal monitor (shows all messages to VTY screen)
    sh mac address-table
    do ? (i.e. do sh run). runs the command from global conf mode

    [Switch Optimization]
    conf t
    line con 0
    logging synchronous
    exec-timeout 30 0
    no ip-domain lookup
    line vty 0 4
    logging synchronous (Retypes line automatically when messages are logged to monitor)
    exec-timeout 30 0 (Idle timeout)
    no ip-domain lookup
    end

    [Setting up aliases]
    conf t
    alias exec s show ip int brief (where: exec=mode, s=alias command for "show ip int brief")


    [Port Security]
    conf t
    int fastethernet 0/5
    switchport mode access (hardcoded as access port - connected to end device. Alternative is trunk!)
    switchport port-security
    switchport port-security max 1 (max 1 mac address)
    switchport port-security violation ?
    protect (allows max mac & blocks the rest)
    restict (allows max mac, blocks the rest & logs violation in Security Violation Count (see sho port security int fa 0/5)
    shutdown (shuts down port)
    switchport port-security mac-address ? (hardcoded mac or sticky)
    end
    sh port security int fa 0/5

    [To configure a range]
    int range fastethernet 0/2 - 24
    switchport port-security

    [Configure Speed & Duplex on Ports]
    conf t
    int fa 0/2
    duplex half | full
    speed 10 | 100
    end

    - Check settings using: show interface fa 0/2, etc

    To start with the basics of configuring a switch,

    then hopefully if I can learn that, start using it and get it up and running, just for experience

    started a topic Cisco 3750g ps-e

    Cisco 3750g ps-e

    Whilst on contract my manager has allowed me to play & learn with a CISCO switch.

    Where do I start ? I've never done anything with a cisco switch.

    I have it hooked up to a laptop and connected to a terminal session, but thats as far as I have gone with it.

    There is no GUI it's all command line stuff

    any ideas where I can start and learn with this.

    It's not needed at work it's purely for my own development.

Working...
