cisco asr1000 aux-port

Hi. I have a Cisco ASR 1006 Router, with the the aux-port connected but i can´t configure the "line aux 0".. the line does not exist in the running config. 

http://www.cisco.com/c/en/us/td/docs/routers/asr1000/install/guide/asr1routers/asr1higV8/asr1_hw2.html

In the related link Cisco says "The AUX port is a diagnostics access port". 

I need to connect Cisco ASR1000 Aux-port with a Cisco CRS Console-Port as a second remote control method.
I Wish to confirm this before deploy several sites in the same way.

Thanks

Long time ago question indeed

Long time ago question indeed, but, as they say better late than never:

If you are unable to see the 'aux' option under the line:

Router(config)#line ?
<0-5> First Line number
console Primary terminal line
vty Virtual terminal

Router(config)#

This is mostly because of this:

Router#show romvar
ROMMON variables:
PS1 = rommon ! >
BOOT_PARAM = root=/dev/ram rw console=ttyS1,9600 max_loop=64
CONFIG_FILE =
BOOTLDR =
IM_ACTIVATE = 00
MCP_STARTUP_TRACEFLAGS = 00000000:00000000
IOSXE_DUAL_IOS = 0
LICENSE_SUITE =
LICENSE_ACTIVE_LEVEL = adventerprise,all:asr1001;
THRPUT =
ISSU_BOOTED_IMAGE =
? = 1
LICENSE_BOOT_LEVEL = adventerprise,all:asr1001;
EULA_ACCEPTED = TRUE
CRASHINFO = bootflash:crashinfo_RP_01_00_20161209-043916-UTC
BOOT =
RET_2_RTS = 16:36:17 IST Thu Jan 19 2017
BSI = 0
RET_2_RCALTS =
RANDOM_NUM = 1297175823
Router#

You have to go to the rommon mode of the router by configuring the router config-reg to '0x0'. Write the configuration, and then reload the router. Then do the following:

rommon>unset BOOT_PARAM

rommon>sync

rommon>reset

Then finally boot the router with the image of your choice. Once the device is up, you should be able to see aux option:

Router(config)#line ?
<0-5> First Line number
aux Auxiliary line
console Primary terminal line
vty Virtual terminal

Router(config)#

Hope this helps. Kindly do rate the response, if helpful.

Thanks,

Aries
