IS this IMA? If so there is a bug where you will see this stuff. An IOS
upgrade will fix this. The bug ID is dr22203 I think.
Also make sure you carrier is using Ascend and not 3Com. There is a
problem with the way Cisco talks to 3Com on the ATM side.

yes - call your telco and complain long and loud. they have a problem
and
they should fix it.
if I were to guess, I would say the problem is at the frame/ATM
interface.
There can be issues with ATM switch code or with frame switch code, or
both,
that are causing this intermittent problem.

Subject: Problem of ATM to Frame Relay connections [7:20239]
Hi all,
Our company is using ATM to Frame Relay connections to connect the head
office to some remote offices. The head office is using Cisco 7200 (ATM)
and
the remote office is using Cisco 2500 (Frame Relay). Some of the offices
are
using T1 Framelink while some of the offices are using 256k Framelink to
the
head office.
Head office
Cisco 7200 (ATM port)
||
||
[ ATM/Frame Relay Cloud ]
| | | |
| | | |
T1 T1 256k 256k
Off1 Off2 Off3 Off4
There was no any problems in the connections. However, at the log file
of
the Cisco 7200 (ATM router), it always show that the line protocol of
the
256k subinterfaces (i.e. Off3 and Off4) are DOWN for several seconds
and
then UP again. e.g.
XXX XXX Line protocol on Interface ATM0/0.4, changed state to down
XXX XXX Line protocol on Interface ATM0/0.4, changed state to up
When I used "show ip eigrp neighbors", it shows that Uptime of Off3 and
Off4
were only several minutes
I had tried to PING the remote offices from the head office and it show
that
there was no any packet lost although the Cisco 7200 log file show the
line
protocol down and up.
Can anyone help me?
Regards.
