Is it possible to re-assign the aux line on ISR series?

[jawill47ec]

For the following from a 28xx series ISR;

Tty    Line Typ     Tx/Rx       A Modem  Roty AccO AccI  Uses  Noise Overruns  Int
      0    0   CTY                    -    -            -      -          -     0      0            0/0      -
      1    1   AUX   9600/9600  -    -            -      -          -     0      0            0/0      -
  0/0/0   2   TTY   9600/9600  -    -            -      -          -     3      0            0/0      -

Is it possible to re-assign the AUX port from LINE 1 to another?  I would like to start the async's

at line 1 similiar to how the 25xx series:

   Tty Typ     Tx/Rx        A Modem  Roty AccO AccI   Uses   Noise  Overruns   Int
     0  CTY                     -     -           -       -        -        0       0             0/0       -
     1  TTY   9600/9600    -    -            -       -         -       0       0             0/0       -

If so, is there a link to Cisco documentation that shows how?

thanks,

james

Hello James,

numbering is fixed, however newer ISR routers allow you to refer to a line in two ways:

or by using a single integer or a slot#/port# notation see:

Router# show line 1/22
   Tty Line Typ     Tx/Rx    A Modem  Roty AccO AccI  Uses  Noise Overruns  Int
  1/22   88 TTY   9600/9600  -    -      -    -    -     0      0    0/0      -
Line 1/22, Location: "", Type: ""

as showed in the document linked by Ganesh.

this is line 88 and 1/22 at the same time.

However, if you are going to use it to build a terminal server the TCP port will be 2000+line# so the best thing to do is to to take a sh line and to note the range of line numbers of async ports.

Also from the same document:

>> The "Line" column displays the actual line number. The actual line           number associated with each interface is determined by complicated  equations           that vary according to the hardware setup (such as a network module,  interface           card or interface card in a network module).

On these platforms, the line numbers have limited significance. The           same can be used in the reverse telnet process. Ideally, rotary under  the line           configuration should be widely used for reverse telnet           applications.

To be noted older routers had aux port as the last one and so its number changed depending on what was installed on it.

With C3600  a fixed numbering (up to 32 lines per network slot position) has been introduced.

Hope to help
