Hi All,
We are seeing some really strange behavior on a Cisco 1721 CPE. It
acts like we are having a connectivity problem with packet loss or
very high latency. There is about 86Kbps to 350Kbps of traffic on it.
It has WIC-1DSU-T1 card and is doing just basic static routes with a
Full T1. There are no errors on the T1. If I log into the router and
try to send say 1000 icmp packets to something on the other end of the
T1, it will go for few packets and then pause for about 15 to 20
seconds before continuing right where it stopped. It never drops any
packets, just freezes and then continues. It does this about every
minute or 2. Has anyone seen this before?
Nothing shows up in the logs and we have rebooted it with no
resolution to the problem. Pings to and through the router from
outside never stop or drop when this happens either, but it is causing
problems with QoS for VoIP. CPU load is nothing and RAM is fine.
#sh proc cpu
CPU utilization for five seconds: 0%/0%; one minute: 1%; five minutes:
2%
#sh mem
Head Total(b) Used(b) Free(b) Lowest(b)

Processor 80A9C858 3134376 1932072 1202304

I/O D99C00 2515976 1661620 854356
854356 854300
Anyone have any ideas?
Thanks.
