"dialer idle-timeout" command

[delahais]

As you can see in my configuration, i use "dialer idle-timeout 300" command :

interface BRI1/0

no ip address

encapsulation ppp

isdn switch-type basic-net3

isdn incoming-voice modem

no cdp enable

ppp authentication pap

interface Group-Async1

ip unnumbered FastEthernet0/0

encapsulation ppp

dialer in-band

dialer pool-member 1

async mode dedicated

ppp authentication pap

group-range 65 76

!

interface Dialer170

ip unnumbered FastEthernet0/0

encapsulation ppp

dialer pool 1

dialer remote-name xxxx

dialer idle-timeout 300

dialer-group 1

no cdp enable

ppp authentication pap

dialer-list 1 protocol ip permit

For me, everything is fine.

My customer tells me that every 5 minutes, the connection goes down in spite of interesting traffic occurs.

I do not understand, what is happen ?

It seems to me that is not the first time that i see theses troubles with this command.

My release is 12.2(13a).

If on the remote end you are connecting to a dialer interface with a dialer-group applied, it is possible that there is no interesting traffic passing across this interface causing the dialer counter o count down on the remote end, hence ending the session .

You really do not need the side that receives the call to be a dialer interface

you have 2 options

1. remove the dialer statement or

2. remove the dialer-group

3. change the dialer-list to permit any

You can do a couple things to verify everything is ok on your side.

1) When the connection is up issue "show caller" this will show you current connections and timeout values.

2) Run debug ppp neg and debug modem to see who sends the disconnect frame.

you are right :

3640A#show caller timeouts

Session Idle Disconnect

Line User Timeout Timeout User in

tty 66 arche - 05:00:00 04:59:56

vty 130 - - 00:05:00 00:04:59

As66 arche - 00:05:00 00:03:56

that works.

I do not understand, why we do not have this information with "show status active" :

3640A#sh isdn active
