'copy system:/running-config'
Address or name of remote host [192.168.64.46]?
Source filename [acl2]?
Configure using tftp://192.168.64.46/acl2? [confirm]
We will take a closer look at using this option in the section
"Configuring Your Router with and TFTP" later in this chapter.
The configuration EXEC commands use a tiered command structure,
which is apparent when you use the CLI mode.
When you first enter the configuration EXEC CLI, you are in global
configuration mode. Global mode commands are used to set most of
the router's global operational parameters and basic network protocol
services. Some examples of these settings are the following:
• Time and date settings
• Security privileges and enable passwords
• User accounts and authentication
• Configuration register settings
• Boot parameters
From global mode, you can enter an interface or process-specific
subcommand mode. Subcommand modes are used for configuring
specific interfaces and router processes. Each mode has a command
set specific to its subprocess and/or a process-specific subset of the
global configuration command set. The most commonly used
subcommand modes are the following:
Async Async interface
BVI Bridge-group virtual interface
Dialer Dialer interface
Ethernet IEEE 802.3
FDDI ANSI X3T9.5
Fast Ethernet Fast Ethernet IEEE 802.3
Port-channel Ethernet channel of interfaces
Group-Async Async group interface
Serial Serial
Loopback Loopback interface
