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.

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)
2)
3)
4)
5)
Switch to switch
Hub to hub
Host to host
Hub to switch
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.

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.
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.

To make, just cut the one side like a straight-through cable and reverse the other end.
Once you connect the cable from your PC to the Cisco router or switch, you can start
HyperTerminal to create a console connection and configure the device

Access Control List
Objective
Understanding the Packet Filtering capabilities of Router. Router can pass or filter the ip
traffic as per required.
The demonstrations include:
1. Standard Access List (1-99).
2. Extended Access List (100-199).
i. STANDARD ACL
•
Standard IP lists (1-99) test conditions of all IP packets from source addresses.
•
In this lab scenario, initially both the Hosts ’A’ & ‘B’ are accessing the Web &
Ftp services but then apply the Standard ACL so that the Host ‘A’ could not
access the Web & Ftp Services.
•
It is recommended that place the Standard ACL near the destination.

Procedure
1. Configuring & Assigning the IP addresses on the routers R1 & R2.
2. Check the routing table on both the routers.
3. Enable the routing protocol on both routers so that hosts on the both routers can
communicate with each other.
4. Check the routing table on both the routers after enabling the routing protocol on
both sides.
5. Make web & FTP servers.
6. Defines a pool of global addresses to be allocated as needed.
7. Defines a standard IP access list permitting those inside local addresses that are to
be translated.
8. Establishes dynamic source translation, specifying the access list defined in the
prior step along with the keyword “overload”.
9. Marks the interface as connected to the inside & outside networks.
10. Verifying the Standard Dynamic translation by commands.

Step 3(A): Verifying the Frame Relay Operation by commands.
FR Client
The show frame-relay pvc command displays the status of each configured connection,
as well as traffic statistics.
The show frame-relay map command displays the DLCI-protocol address map entries,
as well as information about the connection.
The show frame-relay lmi command displays LMI traffic statistics.
FR Switch
The show frame-relay route command displays the status of each configured virtual
circuit connection, as well as their status and route to other interface.

Roll Over Cable
Procedure
1. Attach a PC with terminal emulation software to the Router’s Console port.
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.
3. Enter the command to By-Pass the NVRAM on the > prompt and initialize the
Router by command.
4. Enter no in response to the System Configuration dialog prompts.

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.
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.
