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.
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, 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,
