Basic Cisco configuration commands

1.      Connect PC Ethernet port and Cisco router Ethernet port  by using: Cross-over UTP cable  (cable with pin 1 connected to pin 6 and pin 2 connected to pin 6, both on RJ45 connector) or by using: HUB and two straight UTP cables. 2.      Power on the router and look at the massages appearing on the screen, while the router is booting Part 1 BASIC COMMANDS Using the commands on the router: show version show ip interface brief (or show interface) Answer the following questions: 1. Router name: 2. Router type: 3. IOS version: 4. Memory amount: 5. Flash ROM amount: 6. Number and types of interfaces:

Part 2

Part 3 Set up a new  IP address, mask and Default Gateway  on each  WG PC Each WG should decide which IP addresses will be used (from each subnet) for PC to router connection and for router to router connection .  Start -> Settings -> Control panel -> Network -> TCP/IP Ethernet… -> Properties -> IP address and Gateway Part 4 Displaying the configurations       Enter privilege mode (enable)      Display the configuration saved in NVRAM (show config)      Display the running configuration (show running-config) Setting and changing the configuration       Enter the configuration mode (conf term)      Change the router name (hostname)      Exit the privilege mode (CTRL-Z), you are back in Privileged mode!      Save the configuration (copy running-config startup-config) Setting the passwords (REMEMBER YOUR PASSWORD)       Enter the configuration mode (conf term)      Specify virtual terminal lines you would like to configure (line vty 0 4)      Request login authentication (login)      Set a password for the exec mode (password my_password)      Set a password for the privileged (enable secret my_password)      Exit the privilege mode (CTRL-Z), you are back in Privileged mode! Configuring the interface      Enter the configuration mode (conf term)      Select first ethernet interface       (interface ethernet - you got all the types of interfaces from part 1 task – for example Interface Ethernet0/0)      Select the ip address and subnet mask (ip address your_IP_address  mask )      Enable the interface (no shut)      Exit the privilege mode (CTRL-Z), you are back in Privileged mode! Checking router status and IP connectivity       Check host connectivity (ping connected_PC_ip_address)      Check host reachability (trace connected_PC_ip_address)      Check status of an interface (show interface eth?)      Display debug information (debug ip icmp)      Disable debug information (undebug all) Part 5  Establishing router to router connectivity:  Configuring the Serial interface:   Enter the configuration mode (conf term)      Select first Serial interface      (interface Serial - you got all the types of interfaces from part 1 task – for example Interface Serial0)      Select the ip address and subnet mask (ip address your_IP_address  mask )       Find out which Serial interface got connected DCE and which DTE CISCO cable ·        DTE (Data Terminal Equipment – MALE conector) ·        DCE (Data Communication Equipment – FEMALE connector)       On Serial Interface with DCE cable enable line CLOCK by entering the command: ·        clock rate 1000000       Enable the interface (no shut)      Exit the privilege mode (CTRL-Z), you are back in Privileged mode!   Connect DTE and DCE cable   Checking router status and IP connectivity       Check neighbor router connectivity (ping connected_router_ip_address)      Check status of an interface (show interface serial?)  Provide routers  with info where other (not directly connected) subnets  are by configuring static routes on each router:  The command is:  ip route  ·         is the subnet used for router-to-PC connection on the neighbor router or the subnet between next two routers ·         is IP address of  serial interface on the neighbor router  Check  connectivity  (ping) from your PC to all other PC’s in your WG ·        open DOS window  (Start -> Programs -> DOS) ·        ping host_ip_address  Check  reachibility (traceroute) from your PC to all other PS’s in your WG ·        open DOS window (Start -> Programs -> DOS) ·        tracert host_ip_address Part 6  (optional)  Connect your network to other WG network (by Ethernet or Serial connection): ·        decide which subnet will be used for interconnection ·        configure static routes to other subnets ·        Check  connectivity  (ping) from your PC to all other PC’s (in others WG) ·        Check  reachibility (traceroute) from your PC to all other PS’s (in others WG)
