 Hi,

Is this interface connecting to a hub or some other switch ?

LAN environment , may be some NIC doing unwanted broadcast ?

Try to put a sniffer on the LAN network and see what's happening ?

Ethereal is a great software.

Cheers

Vishal

Subject: Strange show interface output

The following is show interface output. I noticed the txload is extremely
high. The 5 minute output rate is also rediculous high. My users are
complaining about the slow performance. I wonder what the problem is.
Thanks. Yoshi
