I dont' really understand what does that mean....
I dont see any disconnects on my eth0 but mii-diag sees ones...
eth0 is serving about 400 clients and stale transfer is about 11 mbit...
Is my hardware bad ? the other side is a big backbone catalyst..
Any CRC errors in ifconfig ?
Has the Cisco ever been rebooted while the Linux box stayed up?
(Instant errors there...)
Can you look at the error counters on your port in the Cisco or get
someone else to send them to you?
Check that both sides are hard-coded to 100/Full or whatever you're
using. Autonegotiation can be problematic between some manufacturers.
Smells like a bad cable.
