Appendix E – Using Out of Band Management
This appendix covers the setting up of a router. The router's console port, for example on a Cisco router, is an asynchronous
serial port configured as data communications equipment (DCE).
Step 1: Configure the Modem for your Country or Region
Configure the modem defaults to match the requirements of the country/region in which it will be used. For information on
how to do this, see “Step 5: Configure the Modem for your Country or Region” in Chapter 2.
Step 2: Configure for Callback Security in Direct Connect Mode
Callback security requires a caller to give a correct password before sending data to the system. If you do not plan to use
this feature, skip to Step 3.
To Turn Direct Connect Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
Using a terminal program such as HyperTerminal, type the command
AT#Sxxxxxxxx
, where
xxxxxxxx
is your
password (1 to 8 characters long; case-sensitive). Press E
NTER
. The modem responds with
OK
if the setup
password is correct and
ERROR
if it is wrong. The default password is
MTSMODEM
. If you wish to change the
password, then type the command
AT#S=xxxxxxxx
, where
xxxxxxxx
is the new password (1 to 8 characters
long; case-sensitive), and press E
NTER
.
Type one of the following commands:
•
To turn on remote callback security only, type
AT#CBS2
and press E
NTER
.
•
To turn on both local and remote callback security, type
AT#CBS1
and press E
NTER
. When local security is
turned on, you must enter the setup password before you can enter any AT command from a local terminal
except the
AT
,
ATIn
, and
AT#Sxxxxxxxx
commands.
Type
AT&W0
to store the above commands to nonvolatile memory.
To Set the Parity of the Callback Security Messages
The modem’s password prompt and messages parity must match the parity of the computer to which the modem is
connected.
1.
The default parity setting for your modem is
no parity
(
AT#CBP0
). To change the modem’s prompt
messages to use even parity, type
AT#CBP2
and press E
NTER
. For odd parity, type
AT#CBP1
and press
E
NTER
.
2.
To store the new parity value, type
AT&W
and press E
NTER
.
To Assign Callback Passwords
To store a callback password for the first callback memory location, type
AT#CBN0=xxxxxxxx
, where
xxxxxxxx
is
the first password. Press E
NTER
. The password must be unique, must be 6 to 10 characters in length and
case-sensitive, and must not contain a
+
or
-
character.
To store a callback password for the second callback memory location, type
AT#CBN1=xxxxxxxx
, where
xxxxxxxx
is the second password, and press E
NTER
. Note that the memory location number in the command is
incremented by one.
Repeat as many times as necessary until all passwords have been entered.
To review your entries, type
AT&V
and press E
NTER
.
To set the modem for direct connect mode, type
AT%H1
and press E
NTER
.
To Call a Modem Configured for Callback Security
1.
Using a terminal program and an originating modem, dial the number of the modem connected to the
Cisco router, which we will call the “remote modem.”
2.
When connection is established, the remote modem responds:
Password>
3.
Type a direct connection password, and press E
NTER
.
You have three attempts or one minute to enter a
valid password.
4.
If the password is valid, the message
OK Connecting
appears and the modems establish a working
connection.
