Idle time out disconnects dispite being set to 0

I was hoping this was a simple config, but a fault has thrown me a little, am I missing something?

Dispite the idle timer being set to never timeout, the router (803) still becomes disconnected.

Here is the config...

interface BRI0

description connected to Internet

no ip address

encapsulation ppp

dialer pool-member 1

isdn switch-type basic-net3

no cdp enable

!

interface Dialer1

description connected to Internet

ip address *

ip nat outside

encapsulation ppp

no ip split-horizon

dialer pool 1

dialer idle-timeout 0

dialer string *

dialer load-threshold 2 either

dialer-group 1

no peer default ip address

no cdp enable

ppp authentication pap callin

ppp pap sent-username * password 7 *

ppp multilink

crypto map clientmap

The dialer shows me the following:

BRI0:1 - dialer type = ISDN

Idle timer (never), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is data link layer up

Dial reason: ip (s=*, d=*)

Interface bound to profile Di1

Current call connected 00:06:46

Connected to * (*)

BRI0:2 - dialer type = ISDN

Idle timer (never), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is multilink member

Dial reason: Multilink bundle overloaded

Interface bound to profile Di1

Current call connected 00:06:36

Connected to * (*)

Di1 - dialer type = DIALER PROFILE

Load threshold for dialing additional calls is 2

Idle timer (never), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is physical layer up

Number of active calls = 2

Dial String Successes Failures Last DNIS Last status

* 384 0 00:06:44 successful Default

Any help would be greatly appreciated.

Thanks for your time in advance.

yes you are correct these command are pretty much the same , using an acl you can add the key word 'log' to the end , this will let you know what ip is initiating the dialing

What does the remote end look like ? If you have a dialer interface on the remote end this interface could be counting down the dialer idle timer .

The remote end is actually an ISP that I dial direct. It is apparently a permanently nailed up connection.

Re: Idle time out disconnects dispite being set to 0

If they have a dialer-group configured on that router if no interesting traffic passes over that interface during the idle-timeout period , the connection will drop , to be prudent I would check with the ISP on exactly how that interface is configured .

I see where your coming from.

Great advice, thanks for taking the time to respond.

Re: Idle time out disconnects dispite being set to 0

Can you explain the difference between these commands please? I applied the second set to the router and the connection has not dropped (2 1/2 hours continual connection up to yet).

1: dialer-list 1 protocol ip permit

2: access-list 101 permit ip any any

dialer-list 1 protocol ip list 101

I'm under the impression that they both do the same thing, so why does one work and not the other?

Re: Idle time out disconnects dispite being set to 0

It appears that you were indeed correct, the ISP I was using had a default idle timeout option set on the line. This has now been removed and the fault cleared. Please respond to this post so that I may indicate it contains the resolution.

Thank you again for you time and effort.
