How to Use IOS Commands
How to Use IOS Commands
LANBIRD command mode overview
Lanbird IOS is divided into several command modes and the commands which can be
used by mode are defined in each mode.
The command mode mainly consists of the following three layers.
User mode →Root mode →Configuration mode
When the connection to the system is done initially, the user mode is active. Only the
commands, which enable only basic management of the system, can be used in this
mode.
It is possible to enter the root mode from the user mode by using the "root"
command. In the root mode, it is possible to convert to the configuration mode in
which the system configuration can be changed and to use all the commands for the
system management.
It is possible to enter the configuration mode from the root mode by using the "config"
command. In the configuration mode, it is possible to change all the configuration
values of the system.
Entering question mark (?) on the system prompt will display all the commands which
can be used in the current mode.Also, there are on-line helps for all commands.
Whenever it is desired to know how to use commands, enter question mark in the
middle of a command. Then, the types of the commands which can be entered in the
current status and their descriptions will be displayed. The following example shows
the on-line help functions.

User mode
If a connection is made through console without any password or the connection to a
router is made by entering the login password in the network, the default is the user
mode. In this mode, only part of root mode commands are available. In general, the
commands through which one can view the router status are provided. The prompt
ends with ">" as shown next.
LANBIRD>

How to Use IOS Commands
The prompt of the initial product is LANBIRD and it is possible to change it by using
the "prompt" command in the root mode. To exit from the user mode, use the "exit"
command.
Root mode
Because the user can easily change the system configuration in the root mode,
password should be used to access this mode. To enter the root mode, use the "root"
command as shown below. The prompt ends with "#".
LANBIRD> root
Password: *******
LANBIRD#
In this mode, the user can use all the commands and enter the configuration mode to
change the system configuration. To exit the root mode, use the "exit" command as
shown below.
LANBIRD# exit
LANBIRD>
Configuration mode
The user can enter this mode, in which the user can change the router’s configuration,
by using the "config" command. The prompt ends with "(config)#".
LANBIRD# config
LANBIRD(config)#
To exit the configuration mode, use the "end" or "exit" command.
LANBIRD(config)# exit
LANBIRD#

How to Use IOS Commands
Two types of password
* Login password
- Used to make a connection to a router through telnet.
- Password of the initial products: lanbird <-- small letters
- If the login is performed properly, the default after the connection to the router is the
user mode.
* Root password
- Used to move to the root mode after the connection to the router through console
and telnet.
- Root password for the initial products: lanbird <-- small letters

Interface Configuration Management
Interface Configuration Management
Interface number
Lanbird routers use interface numbers in each command. The interface numbers and
corresponding interfaces are shown below.
Interface number Description
0 Ethernet interface 0
1 Serial interface 1
2 Serial interface 2
Ethernet interface configuration
A separate configuration is unnecessary because Ethernet automatically searches 10
Mbps or 100 Mbps interface.
Serial interface configuration
Lanbird routers support various Wide Area Network (WAN) interface protocols.
Especially, Point to Point Protocol (PPP) and Cisco High level Data Link Control
(HDLC) automatic detection function are very convenient because they do not
necessitate a separate configuration of the line protocol in the general router
environment. The following shows how to configure the line protocol of the serial
interface.
Command Description
line-protocol ifnum {autodetect|ppp|hdlc|frame-relay} Configure the line protocol.
As a default of a router, the autodetect in the above table is to automatically detect
PPP or HDLC.
