Timeout on LCP connections

I'm trying to find out why LCP messages from debug are sending TIMEout and droping the call, here the debug messages:

Re: Timeout on LCP connections

The router sends LCP: TIMEout, because it didn't receive the LCP response for its previous LCPREQ packet from client in timely manner (2 secs). You need to configure the router so that it gives milliseconds level time for debug using followinf commands in global config

service timestamps debug datetime msec

service timestamps log datetime msec

So you can see that the initial "O CONFREQ [Closed] id 34" from router to client didn't get replied by client in 2 secs, so router got "TIMEout: Time 0x73A0C State REQsent" and sent another "O CONFREQ [REQsent] id 35 len 25" with id 35.

Re: Timeout on LCP connections

I tried changing those lines and didn't work.

Thanks.

Re: Timeout on LCP connections

After the modem layer comes up, ppp exchange starts between the peers.

What we see here is that this end is sending a LCP req which is not being responded (or if responded by peer not understood maybe due packet corruption)...it will be interesting to see the same debugs on the remote end too.

1)Need to know the remote end node this end is calling into?

2)What modem are we using at both ends? I assume it's external modem on the aux port (line 65).

deb ppp nego on both end will be useful.

Thanks, Mak.

Re: Timeout on LCP connections

As mentioned above, the debug shows that the router is not receiving

a reply from the other device.

This indicates a speed mismatch. Try setting the correct speed under "line " or you can try using "modem autoconfigure discovery" and remove the speed command.

Hope this helps.

Re: Timeout on LCP connections

I'm using the following line aux config:

line aux 0

password 7 ?????????

script dialer DBU

login

modem InOut

modem autoconfigure discovery

transport input all

speed 115200

flowcontrol hardware

This is the standard config I'm using on 50 equipment, only 4 are not working and send the LCP timeout.

Re: Timeout on LCP connections

At remote end (caller) we're using codex3460 modem, at local end using an AS5300 mica modem.

Here the debug ppp neg at remote end

When using modem autoconfigure discovery. you have to remove the

speed command because it should be automatically negotiated.

(note: autoconfigure doesn't only negotiate the speed parameter)

So you should remove the line "speed 115200".

Another option is to try setting the correct speed of the modem

connected to the remote end under line aux 0.

(But don't use it simultaneously with modem autoconfigure)

Has the remote end made a successful connection before?

If not, try removing some commands from your line aux 0.

Something like:

line aux 0

modem inout

modem autoconfigure discovery

transport input all

stopbits 1

autoselect ppp

flowcontrol hardware

Goodluck!

Re: Timeout on LCP connections

Thanks!

I can't remove speed statement, I tried removing lines but still having timeout. I tried also setting the speed removing modem autoconfigure statement, but no luck,

This connection used to be working before, in fact I have other 46 equipment with this config on them:

line aux 0

password 7 (deleted)

script dialer DBU

login

modem InOut

modem autoconfigure discovery

transport input all

speed 115200

flowcontrol hardware

Thanks!

Re: Timeout on LCP connections

If it has been working before, and assuming no changes were made in the

router and on the AS5300, I would try performing some hardware/line isolations.

There are a number of isolations to be done but you should not go beyond

layer 2 because the problem lies between L1-L2,

If it is possible, I hope you could try the following isolations (1-by-1):

1. Replace the cable (router-to-modem).

2. Use another line.

3. Use another modem (preferably the one used in other routers, if possible)

Is it also possible if you could post the output of "show line aux 0"?

Thanks.

Re: Timeout on LCP connections

Thanks!

Let me tell you that we have made this and also we have changed the router itself, we are going to work again with other line and other modem but the modem it's the same for all 50 sites Motorola (Telenetics) 3640.

I'm also posting the sh line aux 0, I heve never used this command before.

rtrSUB04484#sh line aux 0

Re: Timeout on LCP connections

The show line aux 0 simply shows the parameters of the

terminal or line you are using for dialin or dialout.

As you can see from the output, the speed "115200" that

you have configured on the command line was used

to set the speed of line aux 0. Also, the stopbits was

set to 2. I can't comment further about your modem settings

because you mentioned you have used it in many sites.

But If I'm going to compare this with my experience on

this kind of setup, I usually configure line aux 0 with

the exact modem speed capability and a stopbits of 1.

I tried to look for some info about the Telenetics 3460

and I think this modem supports up to 33.6kbps, please

correct me if I'm wrong.

I'm wondering why you can't change the speed command.

Would it be possible if you try, again, using the ff speed:

- 38400

- 33600

- 28800

Try using the "txspeed " and "rxspeed " commands

instead of the "speed " command.

Also, is it possible for you to compare the show line aux 0

of this router to other routers? There kinds of output would

ne useful:

1. show line aux 0 from a working router currently connected

2. show line aux 0 from another working router (not connected)

Thanks and regards.

Re: Timeout on LCP connections

Thanks for your interest.

I already have the exact same configuration on three routers and here the differences:

The one not working:

Noise 3

Overrruns 45/0

The one disconnected but it works:

Noise 0

Overrruns 384/7453

The one connected and working:

Tty A 65

Overruns 2/0

Status: Ready, Active, No Exit Banner, Async Interface Active Modem Detected

Modem state: Ready

Line is running PPP routing for address "ip address"

0 output packets queued, 1 input packets.

Modem hardware state: CTS* DSR* DTR RTS, Modem Configured

About the speed I have configured on the working ones modem autoconfigure discovery but someone (maybe you) suggested removing that line and set the right speed or remove the speed statemet, I'm able to modify speed statement but I cannot delete it to set the default. I tried setting the speeds but I couldn't set 33600, I set 38400 and 28800 but still doesn't work.

About the telenetics 3460 it supports 33.6Kbps.

Thanks

Re: Timeout on LCP connections

Thanks for your help, I tried removing modem autoconfigure discovery statement and again reviewing the speed at modem we fixed to 38400 and it works. I will try the same on the other 3 sites.

Thanks for your help and interest.

Re: Timeout on LCP connections

That's good news. Actually, I was thinking of other possible causes yesterday.

It would be better if you could clear the line aux first after changing any parameters on it prior to performing a dial-up test.

Goodluck!
