Using the Remote CCNA Bundle

Updated 25 October 2008

Contents

The following document attempts to explain the procedures to using the remote bundles for the CCNA course.

Port numbers on Blackbox switch

The following port number to router numbers are used on the black box switch Pod1

Pod 1
03 = Router1
04 = Router2
05 = Router3
06 = WKS1
07 = WKS2
08 = WKS3
Pod 2
09 = Router1
10 = Router2
11 = Router3
12 = WKS1
13 = WKS2
14 = WKS3

Currently we have

In order for you to have access to the Remote Bundle, you will need to do a telnet connection to the IP address 134.7.43.171 or to the hostname cavibundle.ath.cx.  (Please ensure that you download a proper telnet client like Terraterm as the default telnet client on Windows fails!)  With Tera Term, make sure to change the radio button to Telnet, as SSH will not work. This connects to a BlackBox switchbox.

You will need to enter in the appropriate passwords depending on which remote bundle you are using.

Pod1 CCNA Router Bundle
Password: netacad1

Pod2 CCNA Router Bundle
Password: netacad2

CCNA Switch Bundle
Password: ccna3

When you have logged into the Blackbox, you get a list of equipments that you can connect to.  There will be port numbers that associates to every device that is available.

Topology

Pod 1 contains 2620(x2)/2621(x1) series routers, one has dual fast Ethernet, and 2950 switches. Pod 2 contains 2811 routers and 2950 switches. The switch pod uses 2950 switches as well.

Router Topology

There are 3 routers, 3 workstations and 3 switches.
Router 1 connects to WKS01 (via unmanaged switch) on FA0/0.
router 1 connects on s0/0 DCE to router2 s0/0.
Router 2 connects to WKS02 (via unmanaged switch) on FA0/0.
Router 2 s0/1 DCE connects to router 3 s0/1.
Router 3 connects to WKS03 (via unmanaged switch) on FA0/0.
Router 3 s0/0 connects to router1 s0/1 DCE.

Switch Topology

Topology contains 1 router and 2 switches.
The router FA0/1 is connected to switch 1 Fa0/8.
Switch 1 is connected to WKS01 on Fa0/3.
Switch 1 Fa0/1 connects to switch 2 Fa0/1.
Switch 1 Fa0/2 connects to switch 2 Fa0/2. (Note there are 2 links)

Linux Workstations

The Linux workstations can be logged in by using the following username and password.

Username: root
Password: netacad

Please do not change the password!

To configure IP addresses for the Linux Workstation, you will need to use the ifconfig command.

ifconfig eth0 ip.ip.ip.ip netmask nm.nm.nm.nm

For example:

ifconfig eth0 172.16.0.2 netmask 255.255.255.0

Note that if the netmask is not specified, the netmask will default to the class of the IP address in question. For the above example, the netmask would default to 255.255.0.0 if left unspecified.

To configure the default gateway, you will need to use the route command.

route add default gw gw.gw.gw.gw

For Example:

route add default gw 172.16.0.1

FTP, HTTP and TFTP servers should already be installed and enabled on the machines.

Lynx should be used as a text based browser to test http connections.

Switch Bundle

The Switch Bundle is accessed a bit differently to the Router Bundle.  The Switch Bundle is connected to Port 15 of the Blackbox switchbox.

So in order to connect to the Switch Bundle,

CMS> /c 15
You are now connected to the Switch Bundle.
Switch-Bundle>

The enable password is netacad.

Switch-Bundle> enable
Password: netacad
Switch-Bundle#

All the devices in the Switch Bundle are configured with a name.

switch1 – For Switch 1
switch2 – For Switch 2
router – For Router
wks1 – For Workstation 1
wks2 – For Workstation 2

For example, this will connect us to Switch 1

Switch-Bundle> switch1

To exit from the connection, you will need to use the standard Cisco break sequence.

Ctrl-Shift-6 and X

This will bring you back to the Switch-Bundle> console.

The show session command will show you all the sessions that are established to the different devices

Switch-Bundle>show session
Conn Host                Address             Byte  Idle Conn Name
*  1 switch1             192.168.0.1            0     0 switch1

To disconnect totally from the devices, you will need to use the disconnect command together with the connection number.

Switch-Bundle>disconnect 1
Closing connection to switch1 [confirm]

In some cases, the lines might not connect properly and this will involve you clearing the tty lines to the devices.  This is done by the following command:

Switch-Bundle# clear line tty line_number

Switch1 – Line Nunber 1
Switch2 – Line Nunber 2
Router – Line Nunber 3
Wks1 – Line Nunber 4
Wks2 – Line Nunber 5

When you have finished ..

Please ensure that you erase all configurations and reload the router and switches.  Also reboot the workstations that you have used.

Remote Power Manager is in place.

Telnet 134.7.43.171 or cavibundle.ath cx.
password is power
connect with /c16
then the power manager ask you to enter password as well
For pod1 enter netacad1
For Pod2 enter netacad2
For Switch bundle enter ccna3

Then you can turn on, off and boot the devices.

/Boot   Boot Plug n
/On     Turn On Plug n
/Off    Turn Off Plug n

Performing a password recovery

Sometimes, a router will be configured with a password on it that another student has inadvertently set to the wrong value.

the default passwords should be cisco for line console and vty passwords, and class for the enable secret.

Here is how to do a password recovery on the routers in the bundle:

Note that you will need 2 copies of Tera Term open, both connected to
cavibundle.ath.cx.

In the first copy connect to the bundle you are using, i.e. netacad1 or netacad2.

in the second copy connect to the power manager section of the serial switch by using the password power

Enter

/c 16

to connect to the power manager

once connected to the power manager you will be asked for the password for the bundle you wish to control, key in netacad1 or netacad2

This will show a list of routers and their power status.

To perform a password recovery do the following:

alt-tab into your power manager control screen, the prompt should be

RPM>

turn off the router you need to reset the password on.
for example to turn off router 1:

/off 1
confirm this by pressing y then return.

wait about 20 seconds for everything to settle and power up the router.

/on 1

confirm your action.

Once you have powered on the router you have aproximately 45 seconds to alt tab to your other terminal window and press alt-b to send a break.
If you are successful, you should end up at

rommon2>

which is the rom monitor mode on the router

If you miss the bootup window of opportunity you will have to power cycle the router again from the power manager screen.

Once in rommon mode, you need to set the configuration register to bypass the startup configuration.
execute the following command:

confreg 0x2142

now execute the reset command to reboot the router:

reset

once the router comes up you should be asked whether or not to enter the initial configuration dialog. say no.

now enable in order to change configuration.
If you do not care about the existing configuration do the following:

erase startup-config
config t
config 0x2102
end

now execute reload answering yes to both confirm prompts.

If you care about the configuration in the router you will have to do the following:

copy startup-config running-config
config t

Now you MUST reset the enable secret and other passwords to known values before dropping out of enable mode, otherwise you'll be locked out again!

don't forget to use the

config 0x2102
command to reset the configuration register.
Failure to do this will result in the router continuously bypassing the startup configuration.

reload your router when finished.

When the reset is complete disconnect from the remote power manager.
