IR1101 - outgoing console via async port

[dieter.lievens]

Hi all,

I am trying to establish an outgoing console over the async port of a IR1101. I am getting a bit stuck, I'm afraid.

I am trying to establish a outgoing serial connections towards another cisco switch over the async interface of the router. The relevant config is:

interface Async0/2/0
no ip address
encapsulation relay-line

line 0/0/0
no exec
transport input all
line 0/2/0
no exec
transport input all

I tried with stopbits, with straight and roll-over cable. No luck.

I simply get this:

XXXXX1#telnet 172.31.244.4 2050 /vrf OOB
Trying 172.31.244.4, 2050 ... Open

I can succesfully login, but the console is not giving me anthing.

Is what I am trying to do possible? Indeed, it's for a out of band solution

Hi, Anybody has resolved this issue? Thank you

Hello,

the only bit of information I could find is that apparently you need to configure this as well:

IR1101(config)#relay line 0/2/0 0/0/0

Then again, the connection with the switch is made. What port on the switch is the async interface connecting to ?

I'm experiencing a similar issue:

We're trying to create a terminal server to be reached over cellular.  We have an IR1101 with an attached IRM-1100-4A2T, offering 4 Async ports 0/4/0 through 0/4/3.  Going through the documentation, I have created the following configuration to reach a switch's console port through as0/4/0, but it doesn't seem to be working, and I don't really know where to go from here.  When I telnet to the loopback on the port, I telnet into the router instead of bringing up the console port connected to the switch.  Any direction would be appreciated.

Hi,

I got it working with the configuration below, but the important part was the cable. I had to build my own. See table 2 on " Connecting and Troubleshooting IoT Devices Using Asynchronous Serial Interfaces White Paper - Cisco ".

line 0/2/0

 exec-timeout 15 0

 transport preferred none

 transport input all

 transport output none

line 0/3/3

 exec-timeout 15 0

 transport input all

 transport output none

interface Async0/2/0

 no ip address

 encapsulation relay-line

interface Async0/3/3

 no ip address

 encapsulation relay-line

 media-type rs232

telnet <loopback-ip> 20xx (xx = line number)

thank you for posting this. I'm currently evaluating something similar but need 16+ async ports.
