CCNA LAB Practice - Ethernet CABLES

noreply@blogger.com (Knowledge for You) — Fri, 29 Apr 2011 10:02:00 +0000

Ethernet CABLES

Objective

This lab demonstrates how to make an Ethernet Cables.

The types of Ethernet cables are:

1) Straight-through cable

2) Crossover cable

3) Rolled cable

i. Straight-Through Cable

The straight-through cable is used to connect

1) Host to switch or hub

2) Router to switch or hub

Four wires are used in straight-through cable to connect Ethernet devices. It is relatively

simple to create ; Figure shows the four wires used in a straight-through Ethernet

cable.

Diagram

Notice that only pins 1, 2, 3, and 6 are used. Just connect 1 to 1, 2 to 2, 3 to 3, and 6 to 6. However, remember that this would be an Ethernet-only cable and wouldn’t work with Voice, Token Ring, ISDN, etc.

ii. Crossover Cable Cable

The crossover cable can be used to connect

1) Switch to switch

2) Hub to hub

3) Host to host

4) Hub to switch

5) Router direct to host

The same four wires are used in this cable as in the straight-through cable; we just connect different pins together. Figure shows how the four wires are used in a crossover

Ethernet cable.

Notice that instead of connecting 1 to 1, etc., here we connect pins 1 to 3 and 2 to 6 on each side of the cable.

Diagram

iii. Rolled Cable

Although rolled cable isn’t used to connect any Ethernet connections together, you can use a rolled Ethernet cable to connect a host to a router console serial communication (com) port.

If you have a Cisco router or switch, you would use this cable to connect your PC running HyperTerminal to the Cisco hardware.

Eight wires are used in this cable to connect serial devices, although not all eight are used to send information, just as in Ethernet networks. Figure shows the eight wires used in a rolled cable.

Diagram

This is probably the easiest cable to make, because you just cut the one end off on one side of a straight-through cable and reverse the other end.

Once you connect the cross cable from your PC to the Cisco router or switch, you can start HyperTerminal to create a console connection and configure the device

Procedure

Enable the port Security of the Interfaces.
Define the Max Mac Addresses on the Interfaces.
Verifying the Port Security of the Interfaces by the command.
Define the permanent entry of the both Hosts on the switch.
Ping from Host ‘A’ to Host ‘B’.
Change the interfaces of the Hosts & verifying the Results by the ping command.

Configuration

Step 1: Enable the port Security of the Interfaces.

1900-SWA(config)#int Ethernet 0/1

1900-SWA(config-if)#port secure

1900-SWA(config)#int Ethernet 0/2

1900-SWA(config-if)#port secure

Step 2: Define the Max Mac Addresses on the Interfaces.

1900-SWA(config)#int Ethernet 0/1

1900-SWA(config-if)#port secure max-mac-count 1

1900-SWA(config)#int Ethernet 0/2

1900-SWA(config-if)#port secure max-mac-count 1

Step 3: Verifying the Port Security of the Interfaces by the command.

1900-SWA#show mac-address-table security

Action upon address violation : Suspend

Interface Addressing Security Address Table Size Clear Address

-------------------------------------------------------------------------------------------

Ethernet 0/1 Enabled 1 No

Ethernet 0/2 Enabled 1 No

Ethernet 0/3 Disabled N/A No

Ethernet 0/4 Disabled N/A No

Step 4: Define the permanent entry of the both Hosts.

1900-SWA(config)#mac-address-table permanent 0050.DA23.C9DD e0/1

1900-SWA(config)#mac-address-table permanent 0001.0262.FCC4 e0/2

Step 5: Ping from Host ‘A’ to Host ‘B’.

D:\>ping 10.0.0.2

CCNA LAB Practice - Verification Of Spanning Tree Operation in PVST Mode

noreply@blogger.com (Knowledge for You) — Fri, 29 Apr 2011 06:20:00 +0000

Verification Of Spanning Tree Operation in PVST Mode

Since, it is known that Cisco catalyst switches are running in PVST mode, by-default. It means that each spanning tree instance is used for each VLAN. The Root Switch can be different for every VLAN.

Diagram

Procedure

Make a VLAN 5 on both switches.
Set the spanning tree priority on 2950-SWB switch to become a Root Switch for VLAN 5. Otherwise, the default Root of VLAN 5 will be 2950-SWA.
Verified the results on 2950-SWA.
Verified the results on 2950-SWB.

Configuration

Step 1: Make a VLAN 5 on both switches.

2950-SWB(config)#vlan 5

2950-SWB(config-vlan)#name vlan-5

Note:- Commands will be same on 2950-SWA switch.

Step 2: Set the spanning tree priority on 2950-SWB switch to become a Root

Switch for VLAN 5. Otherwise, the default Root of VLAN 5 will be 2950-

SWA.

2950-SWB(config)#spanning-tree vlan 5 priority 28672

Step 3(A): Verified By Show command on 2950-SWB Switch for VLAN 1.

CCNA LAB Practice - Password Recovery

noreply@blogger.com (Knowledge for You) — Fri, 29 Apr 2011 06:07:00 +0000

Password Recovery

Objective

This lab demonstrates how to recover the password of 2500 series Routers. Password Recovery procedure allows you to regain administrative control over the device.

Diagram

Procedure

Attach a PC with terminal emulation software to the Router’s Console port.
Turn off the Router, and turn it on and press the Break Key on the PC within 60 seconds of turning on the Router.
Enter the command to By-Pass the NVRAM on the > prompt and initialize the Router by command.
Enter no in response to the System Configuration dialog prompts.
Enter into the Router and copy the configuration from the NVRAM, change the password & change the value of the configuration register & save the configuration into NVRAM again and reload the Router.

Configuration

Step 1: Attach a PC with terminal emulation software to the Router’s Console

Port.

The configuration register value is 0x2102 by-default. It’s mean that whenever the Router boots, it will read the contents of the NVRAM. So, we need to by-pass the NVRAM at the time of startup for the password recovery.

Step 2: Turn off the Router, and turn it on and press the Break Key on the PC

within 60 seconds of turning on the Router.

The > prompt with no Router name appears at the Router screen.

Step 3: Enter the command to By-Pass the NVRAM on the > prompt and

initialize the Router by command.

> o/r 0x2142 (to boot from flash)

> i (initialize the Router)

Step 4: Enter no in response to the System Configuration dialog prompts until the

following message appears.

Press RETURN to get started!

Step 5: Enter into the Router and copy the configuration from the NVRAM,

change the password & change the value of the configuration register &

save the configuration into NVRAM again and reload the Router.

Router>enable

Router#copy stratup-config running-config

Router#config t

Router(config)#no enable password

Router(config)#enable password cisco

Router(config)#configuration-register 0x2102

Router(config)#end
