AIM-CUE Session

AIM-CUE Session

We’ve covered so far a bunch of very interesting topics on our journey to familiarize ourselves with the AIM-CUE, things like, unpackaging, physical installation, logical connection, IP addressing, IP Unnumbered and also IP Routing using an static route, we are ready to move forward to the next step, opening our very first session, let’s do that.

First let’s double check we do have proper connectivity:

  • ping 172.16.1.103
vgw#ping 172.16.1.103
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.103, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
vgw#

Opening a session

You’ll see that at the end of the day, opening a new session with our CUE is just like going from one device to the other using telnet, see the CLI command we have to use below:

  • service-module Service-Engine 0/1 session
vgw#
vgw#
vgw#service-module service-Engine 0/1 session
Trying 172.16.1.1, 2386 ... Open
SYSTEM ONLINE
CUE-751> 
CUE-751> 
CUE-751>

Congratulations! You are finally inside the Cisco AIM-CUE for the very first time, awesome! job well done!

Returning to the original (router) session

Permanently

Once we are done with whatever we were doing on our AIM-CUE and we want to go back to the router, closing permanently the current connection with CUE, we must use for these cases, the “exit” CLI command, see below:

CUE-751> exit

[Connection to 172.16.1.1 closed by foreign host]
vgw#

Briefly, wanting to resume the session

Because we are just opening a new telnet session with our CUE, as you can imagine, we can also use the very well known key combination (Ctrl-Shift-6-X) to get back to the original session, but leaving the possibility to resume the current CUE session by just pressing Enter.

ctrl shift 6 x
Press Ctrl+Shift+6, then release all (three) keys, and then press “X”

See below the effect of pressing “Enter” immediately after the key combination.

vgw#
[Resuming connection 1 to 172.16.1.1 ... ]
CUE-751> 
CUE-751>

As you can see, the shell resumes the CUE session, and that is very useful for cases where configuring the CUE we have to wait for it to complete a given task.

We don’t have to just sit in front of the computer waiting for CUE to complete its task, what we can do instead, is to go back to router to do other things meanwhile, knowing that we can quickly resume the CUE session, because it was left intentionally open.

Show sessions currently open

From the original (router) session we can check if there is any open session, see command below:

  • show sessions
vgw#show sessions 
Conn Host                Address             Byte  Idle Conn Name
*  1 172.16.1.1          172.16.1.1           0      0  172.16.1.1

vgw#>

Disconnect Session

The output of the “show sessions” command is necessary to get the session ID, in the example above that number is “1”, you’ll use the session ID number to close that particular session, see command below:

  • disconnect 1
vgw#disconnect 1
Closing connection to 172.16.1.1 [confirm]
vgw#

The “Good Old” question mark symbol

Now that we are finally inside our CUE for the very first time, we can ask for help using the old good question mark symbol, you can see a list of the available options below:

Where to go from here

I think we have now a lot of “home-work” to do, many options to check and the opportunity to finally get to know ALL about our AIM-CUE, let’s continue with a few more “show” CLI commands then.
