So I'm trying to connect the AUX ports of 2 2610's back to back. I am
following a known procedure on CCO where you can connect 2500's AUX ports
back to back.
http://www.cisco.com/warp/public/793/access_dial/auxback.html
So I follow exactly what they do. But it doesn't work. Maybe the problem
is that 2600's don't do back2back aux ports (the CCO example was for
2500's). But that doesn't make much sense, because why not? Anyway, has
anybody ever gotten AUX 2600's (or any router for that matter) to connect
back to back?
For example, here is the Async config on one of the 2610's.
interface Async65
ip address 192.168.10.1 255.255.255.0
no ip directed-broadcast
encapsulation ppp
async dynamic routing
async mode dedicated
Here is the aux line config:
ine aux 0
modem InOut
transport input all
speed 38400
flowcontrol hardware
So I believe that everything is good, it's exactly like the CCO config.
Yet, the async interface just keeps bouncing up and down. For example:
r1#
1d19h: %LINK-5-CHANGED: Interface Async65, changed state to reset
r1#
1d19h: %LINK-3-UPDOWN: Interface Async65, changed state to up
r1#
1d19h: %LINK-5-CHANGED: Interface Async65, changed state to reset
Here's what happens when I debug async packet
r1#debug async packet
Async packet I/O debugging is on
r1#
1d19h: %LINK-5-CHANGED: Interface Async65, changed state to reset
r1#
1d19h: %LINK-3-UPDOWN: Interface Async65, changed state to up
r1#
1d19h: APPP65: Output packet, len = 24, header = FF 3 C0 21
1d19h: APPP65: Output packet, len = 24, header = FF 3 C0 21
1d19h: APPP65: Output packet, len = 24, header = FF 3 C0 21
r1#
1d19h: APPP65: Output packet, len = 24, header = FF 3 C0 21
1d19h: APPP65: Input packet, len = 24, header = FF 3 C0 21
1d19h: APPP65: Output packet, len = 24, header = FF 3 C0 21
r1#
Here's what happens when I debug async framing
r1#debug async framing
Async interface framing debugging is on
r1#
1d19h: %LINK-5-CHANGED: Interface Async65, changed state to reset
r1#
1d19h: Async65: Reset PPP framing on TTY65
r1#
1d19h: Async65: Setup PPP framing on TTY65
1d19h: As65 PPP: Processed packet cached during autoselect
r1#
1d19h: %LINK-3-UPDOWN: Interface Async65, changed state to up
r1#
