intermittent problem atm interfaces

I have installed a connection point to point G. HDSL with ATM interfaces,
and every so often 4 or 5 days, the interfaces be longer ping and services that go through that experience intermittent link, the only thing that is not affected VoIP

and when both routers reboot resolves the problem points, but after days back and I passed.

that might be?

I need help

en español:

Tengo instalado una conexion punto a punto G.HDSL con interfaces ATM,
y cada cierto tiempo 4 o 5 dias, las interfaces dejan de darse ping y los servicios que pasan por ese enlace sufren intermitencia, lo unico que no se afecta es VoIP

y cuando reinicio los routers de ambos puntos se resuelve el problema, pero al cabo de dias vuelve y me pasa. 

que podria ser?

Necesito ayuda

Try loading 12.4(5B)on the 2851 as well.

Re: intermittent problem atm interfaces

I have in my router Core

Cisco 2851 (revision 53.51

With IOS

C2800NM-ADVENTERPRISEK9-M Version 12.4(15)T5 release Software (fc4)

remote router

C2801-ADVIPSERVICESK9-M Version 12.4(5B) release Software (fc2)


I have other connections to that router and other points of that type to another atm card with another service provider

and that connection only gives me problems

Re: intermittent problem atm interfaces

Try resetting one only in the attempt to find which side has a buggy IOS.

I discovered that by simply restarting the core router  Cisco 2851has IOS

C2800NM-ADVENTERPRISEK9-M Version 12.4(15)T5 release Software (fc4) . the issue is resolved.

we have asked our service provider we Rebic physical lines for the problem is presented and tested and are fine.

they say it can be a problem iIn Trasnportes protocol, we have configured EIGRP.

Thank you very much for the help you've given me so far ..

Re: intermittent problem atm interfaces

Greetings, has had returned to give feedback of what you suggested because I suggested it could be an EIGRP protocol error, which disables yconfigure static routing, but after several days the problem occurs again.

I wanted to ask before doing what you suggested, if a problem with the router IOS does not affect others because G. HDSL links that I have configured on that router. ???

Re: intermittent problem atm interfaces

Sorry, I do not understand your question.

Your problem is buggy IOS.
