Experiment 15.1

	Chapter 15
15.2		15.3

Your task in this experiment depends, of course, on the specific hardware that you have to work with. "vendor's documentation" is usually not well known for its clarity, so in the interest of reducing obfuscation, here is how you configure a Cisco 1605R router.

You will need a cable with a DB9 to RJ45 adapter. Begin with the router off.

Connect the cable from a com port on a linux box to the console port of the router.

On the box type minicom -s.

Choose "Serial Port Setup".

Choose "E (Bps/Par/Bits)".

Choose "E (9600)".

Choose "Save setup as dfl".

Choose "Exit".

Turn on the router.

To the question "Initial Config Dialoque?" answer "yes".

To the question "Basic Management Setup" answer "yes".

Enter a hostname and three passwords. Password 1 is the "enable secret" password. It protects access to privileged execution and configuration modes. Password 2 is used when you do not specify an enable secret password. It is mainly used with some older software versions. Password 3 is the virtual terminal password used to protect access to the router over a network interface.

On the interface menu type "ethernet0" and enter an ip address.

Do the same for ethernet1.

Choose [2] Save this configuration to nvram and exit.
One additional item: in the configuration dialogue you should be given the opportunity to configure SNMP. You should do that at this point in time (I did not and regretted it later). This involves little more than choosing an RO, read-only, community string and an RW, read-write, community string. The former will have to be set for use in Experiment 17.4 to get information from the router. It is worth thinking about what you could do with read-write access to a router.
