VTY line passwords.

You can add an IP address to an interface with the ip address com-
mand. You need to get into interface configuration mode first; here is
an example of how you do that:
config t
int e0 (you can use int Ethernet 0 too)
ip address 1.1.1.1 255.255.0.0
no shutdown
Notice the IP address (1.1.1.1) and subnet mask (255.255.0.0) are con-
figured on one line. The no shutdown (or no shut for short) command
is used to enable the interface. All interfaces are shut down by default.
13.
You can add identification to an interface by using the description
command. This is useful for adding information about the connection.
Only administrators see this, not users. Here is an example:
config t
int s0
ip address 1.1.1.2 255.255.0.0
no shut
description Wan link to Miami

You can add the bandwidth of a serial link as well as the clock rate
when simulating a DCE WAN link. Here is an example:
config t
int s0
bandwidth 64
clock rate 64000
