Connecting to an Ethernet Port
Cisco 1900 IOS Configuration Commands 573
The Catalyst 1900 series of switches have fixed port types. They are not
modular like the 5000 series switches. The 1900 switches use only 10BaseT
ports for workstations and 100BaseT or FX for uplinks. Each switch has
either 12 (model 1912) or 24 (model 1924) 10BaseT switch ports, each having
one or two FastEthernet uplinks. The 100BaseX ports are referred to as
ports A and B. To connect the ports to another switch as an uplink, you must
use a crossover cable. It would be nice if they had a button for this function,
but they don’t.
When connecting devices like workstations, servers, printers, and routers to
the switch, you must use a straight-through cable. Connecting between
switches uses a crossover cable.
When a device is connected to a port, the port-status LED light comes on
and stays on. If the light does not come on, the other end might be off, or
there might be a cable problem. Also, if a light goes on and off, there is a possible
auto-speed and duplex problem. I’ll show you how to check that in the
next section. If you do not have a device connected to the switch, the port
light will come on when booted, and then it will turn off.

In this section, I will show you how to configure the basics on the 1900
Catalyst switch. I will show you how to
� Set the passwords
� Set the hostname
� Configure the IP address and subnet mask
� Identify the interfaces
� Set a description on the interfaces
� Define the duplex of a port
� Verify the configuration
