Lost of packets in LAN

Hi my friends,

I am studying for CCIE Lab R&S, but a problem at my work is getting me
nervous this days.

Topology:

7200 - fastethernet 0/1 (100Mbps FULL) <--------------> 6500 - fastethernet
5/48 (100Mbps FULL)

Every time that I started a ping of 1000 packets of 100 bytes, I lost ALWAYS
1% of the total of packets sent.

It is a strange behavior because I am in LAN .

Does anyone get a similar problem?

7200 fa0/1 is configured with encapsulation dot1q with 2 VLANS and 6500 side
is configured with trunk .

We have tried to change cable, port...

The utilization in fa0/1 7200 port is average 40Mbps to 50Mbps.

There aren4t errors in this interfaces.

Thanks for anyone can helps

Rodrigo
