EFERENCE
If a Gigabit Ethernet switching module port has autonegotiation
enabled with the port enabled, but the remote end of the connection
has autonegotiation enabled with the port disabled, the enabled port
goes on-line and the port LED lights green. The disabled port stays
off-line.
To avoid such problems, 3Com recommends that you always set the
connected port pairs to the same mode, in one of the following ways:
Enable autonegotiation at both ends of the connection.
Disable autonegotiation at both ends of the connection and statically
configure each endpoint identically.
Either way prevents mismatches and the associated errors.
