[cisco-nas] AS5350 Connection Problems

[Francisco (fxdomin2)]

We're running into something similar, however, it's on
AS5300's with 12.2-2.XB11
Our network provider who "manages" these units says that
it's due to the existence of several viruses (mblast and
nachi) on the internet causing ICMP related issues.
Apparently, the Cisco Advanced Network Services Engineers
(ANS) is working on the issue for the last three weeks, but,
they haven't found a workaround.

If anyone has seen this or is experiencing this, have a fix,
etc. please let us know (Dennis, have you seen this?).

Currently we need to have our as5300's reloaded every 2
hours to bring the unit back to a useable state (all 25 of
them). If left too long before rebooting, no traffic will
pass (so no telnet etc.), users get stuck, and we regularly
get fast busy signals. From a financial standpoint, this is
killing our business.

	We seem to have a spuratic problem with users connecting,
but then
not being able to send/receive any data. The call will start
like normal,
then after about 8K of data, sessions just stops sending or
receiving
anything. I experienced it myself Sunday afternoon from my
dial-up
connection. Since this is a production enviroment I am
having trouble
tracking the problem. Even pings from my dialup computer to
our local
severs will stop. I could ping the AS5300, but nothing on
the ethernet
side. I switched to my laptop and it did the same thing. I
drove to the
office and everything was fine. I drove home, the problem
was gone. I have
in the past told yours to reboot, that windows was causing
the problem but
this is not the case. I think rebooting is just buying time
until the
problem goes away. This seems to come and go, but lately I
am
hearing more and more complaints. Where do we go from here?
Phone
conditions seem normal, no excessive retrains or noise.

2 AS5350's, not sure if one or both are doing it. Both are
less than 1
year old.

IOS 12.2-2.XB11

One has beening running XB11 for several weeks, the other 2
days. Before
that we were using XB8. The problem was present before the
upgrade.

Any suggestions would be greatly appreciated.

Thank You,
John McKinney
