The Work Before Starting Router
Rounter’s physical Port
Number shall be arranged in the form of <type><slot>/<port>.
The comparison table of type and name is as follows:

The
fixed number is distributed to the value of Slot according to expansion slot
of WIC/VIC from right to left in transverse
direction and from the bottom up longitudinal direction . The fixed number for standard configuration is 0,
WIC expansion slots or VIC expansion slots are numbered in
the aforementioned order
commending from 1.
The
value of port is numbered from right to left, starting from 0. If there is
only one port, the port is numbered 0.
The
number list for the product lines determined on the said numbering rule is as
follows:

The
Work Before Starting Router
The
following steps shall be confirmed befor
starting the Router for Configuration
1.
The
hardares of routes are put in rights places on the reuqirements specified in
the manual
2.
The
simulated program is installed at the terminal of PC
3.
Based
on IP protocal, the following items is determined:
· IP
Addrerss Allocation Planning
· Which kind of WAN Protocol that is to run at the port (such as Frame Relay, HDLC, X.25, etc)
· When a question mark is entered, the list of current usable commands will be available immediately.
Router> ?
· Enter some already known characters, then enter question mark closely (no blank) the command starting with already known characters will be shown.
Router>
s?
·
Enter command, followed closely
by spacebar and question mark, list of command parameter will be available. Router>
show ?
· Press “Up” direction key,
the entered commands will be displayed, and continue to press “Up”
direction key, the more entered commands before will be shown.
Router’s command line interface is classified into multiple models. Each command model permits the different components to be configured with the router. The current usable commands dependents on the chosen command model . The list of current usable commands will be displayed by entering queston mark (?) under each command model. The following table lists the frequently-used command models:
Command

When
powe is on, user enter “aaa” |

|
Use
command “Exit or Quit” |
Management
Model |
Input
command “enter or enable” under user model |
router#
|
Use
command “Exit or Quit” |
Overall
Configuguration Model |
Enter
command “config” under management model |
router_config# |
Use
command “exit” or “quit” or “Ctrl-Z” to restore management
model directly. |
Interface
Configuration Model |
Under
overall configuaratrion model, enter command “interface”, such as
interface s1/0. |
router_config_s1/0# |
Use
command “exit” or “quit” or “Ctrl-Z” to retore management
model directly. |
Port Configuration Model |
Under
global configuration model, enter command “interface”, such as
“interface s1/0” |
router_config_s1/0# |
Restore
to managemen model by using command “exit” or “quit” or
“Ctrl-Z” directly.
|
Each command model prevents using some command subensembles. If trouble occurs after command is entered, the interfece prompt shall be checked and the question mark (?) shall be input for getting the list of usable commands. Maybe a mistake is made in command model or syntax.
In the following examples, the new command model indicated by the changes
in the “Notice” interface prompt shall be observed.
router>
enter
Password:
<enter password>
router#
config
router_config#
interface s1/0
router_config_s1/0#
quit
router_config#
quit
router#
If a
command needs to be cancelled or default attribute needs to be retored, it can
be done by adding key word “no” before most of commands
In
orfer to restore the orignal configuration quickly after the system is
restarted or accidental power down, the changes in the configurations shall be
saved. By using the command “write” under Management Model or Global
Confuguraion Model, the changes in the configuration can be saved.
