Notice that as soon as I pressed Enter, the hostname of the switch appeared.
Remember that from global configuration mode, which you enter by using the
config
t command, the running-config is changed. Any changes you make in
this mode take effect immediately.
Setting IP Information
You do not have to set any IP configuration on the switch to make it
work. You can just plug in devices and they should start working, just like
they would on a hub. There are two reasons why you would set the IP address
information on the switch: so you can manage the switch via Telnet or other
management software, or if you wanted to configure the switch with different
VLANs and other network functions. VLANs are discussed in Chapter 6.
The Catalyst 1900 switch has some default settings already configured on
the switch from the factory. The default settings on the switch are as follows:
IP address and default gateway
0.0.0.0
CDP
Enabled
Switching mode
FragmentFree
100BaseT ports
Auto-negotiate duplex mode
10BaseT ports
Half duplex
