Hi Suresh,

You need to configure modem related configs under an AUX line. Find the AUX line you have by issuing the command show line

Assuming that your AUX line is 1. then the config may looks as below

line 1

Speed xxxx (you need to run a debug in order to know the exact speed)

stopbits 1

flowcontrol hardware

modem InOut

transport input all

You may know need to determine the modemcap. You may use the below link to debug

Hi Suresh,

Are you just looking for reverse telnet to aux port? Or you have a modem with PSTN line to perform OOB mgmt?

Thanks

Hi Suresh babu,

Please use following process...

1: Connect the cable from the AUX port of the router to the modem,

2: # show line

3: you get the result like as mentioned below

#show line

   Tty Typ    Tx/Rx    A Modem Roty AccO AccI  Uses  Noise  Overruns  Int

*    0 CTY                  -    -     -    -    -     0      0     0/0      -

    65 AUX  9600/9600  -    -     -    -    -     0      1     0/0      -

    66 VTY                  -    -     -    -    -     0      0     0/0      -

    67 VTY                  -    -     -    -    -     0      0     0/0      -

4: Use the following commands to configure the router AUX line:

We have previously verified that the AUX port is on line 65:

#line 65

(config-line)#modem inout

(config-line)#speed 115200

(config-line)#transport input all

(config-line)#flowcontrol hardware

(config-line)#login

(config-line)#password cisco

Optional Configuration: If the router does not have an enable secret password,

incoming connections will not be able to enter the enable mode. To allow incoming calls to enter enable mode,

use the enable secret password command to setup the enable secret password.

Use the reverse telnet method on the modem to configure the appropriate initialization string.

#Telnet 172.22.53.145 2065

The IP address 172.22.53.145 is the Ethernet address on the router.

2065 represents 2000+line 65.

Trying 172.22.53.145, 2065 ... Open

    OK
