Connecting to a Cisco Router Console Port
The console port on the Cisco IOS® router is an asynchronous serial port configured as data
communications equipment (DCE). For Cisco 1000, 1600, 2500, 2600, and 3600 series routers, the console
port uses an RJ-45 connector.
WARNING: Do not connect the modem to the Cisco router’s auxiliary port. This procedure and document apply only
to the Cisco router’s console port.
Step 1: Configure the Modem for your Country
Configure the modem defaults to match the requirements of the country in which it will be used. For
information on how to do this, see “Step 5: Configure the Modem for your Country” 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. Note: Setting the modem for callback security in direct
connect mode disables the remote configuration feature of the modem.
To Turn Direct Connect Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
1.
Using a terminal program such as HyperTerminal, type the command AT#Sxxxxxxxx, where
xxxxxxxx is your password (1 to 8 characters long). 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), and press E
NTER.
2.
Type one of the following commands:
· To turn on remote callback security only, type AT#CBS2 and press ENTER.
· To turn on both local and remote callback security, type AT#CBS1 and press ENTER. 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.
3.
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 ENTER.
To Assign Callback Passwords
1. 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 must not contain a + or - character.
2.
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.
3.
Repeat as many times as necessary until all passwords have been entered.
4.
To review your entries, type AT&V and press ENTER.
5.
To set the modem for direct connect mode, type AT%H1 and press ENTER.
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>
