Hi ,
i'm getting crazy about the problem below.
We aggregate xDSL customers using PPP (PPPoA or PPPoE) over PA-A3 ATM
adapters.
Now, some customers are experiencing very high tcp packet loss but when
we test ATM (with ATM OAM pings) we don't see any packet loss. It is
possible that it is a problem on the router? Only some customers are
experiencing the problem. We tried anything on the router (delete pcv,
change PPP type etc) but problem persist.
I'm pretty sure that problems are on ATM provider, but on ATM side what
i need do check? ATM Buffers? ATM Errors? My ATM provider say that ATM
ping are enough to check that ATM network is working well but I'm sure
that problems are atm related. Maybe a IOS Bug?
Thanks for any help
Mark
