To get started, open HyperTerminal and start a
new connection. The terminal session should be
setup using 9600Baud, 8 bit, no Parity, and no Flow
control.
For those who are familiar with the Cisco IOS you
may wish to jump ahead to the commands. For the
rest, keep reading and we’ll walk you through it step
by step.
Along the way we’ll even explain why we use the
commands below so that you have some basic under-
standing of what you are doing. Hopefully you will
walk away with some new found knowledge.
Privileged EXEC Mode
Now that we are connected to the switch let's
login. When logging into a Cisco switch under the
default configuration, you are in user EXEC mode
(level 1). In EXEC mode, you have limited access to
the status of the switch. However, you can't make any
changes or view the running configuration file.
Because of these limitations, you need to type enable to get out of user EXEC
mode. By default, typing enable takes you to “Privileged” EXEC mode (Level 15).
In the Cisco IOS, this level is equivalent to having root privileges in UNIX or
administrator privileges in Windows. In other words, you have full access to the
switch.
Let’s get started on the configuration of your switch. Type “enable” command
at the prompt. When prompted, enter the password and press Enter again. If no
password has been defined just press Enter.
NOTE: The command prompt now ends with “#” indicating you are now at the
Privileged EXEC mode (Level 15).
Global Configuration Mode
To enter the IP address and Subnet Mask for the VLAN or configure the switch
ports you must first enter the configuration mode. To enter the global configuration
mode on the 3750G/3560G type “Config T” and press enter. This places the switch
in Global configuration mode and will allow configuration from the terminal
window for the selected interface. You should now have the switch (config)#
prompt.
Configuring the VLAN Interface
A VLAN is a switched logical network that is segmented based on the function
or application. VLANs are virtual LANs but have the same attributes as the physical
LAN. VLANs allow a user to create a virtual broadcast domain in which traffic can
be isolated to keep it reaching unwanted destinations. Any switch port can belong
to a VLAN, and unicast, broadcast, and multicast packets are forwarded only to
those end stations assigned to that VLAN.
