It is a requirement of the GigE standard to do autonegotiation. Turning it off would be a violation of the standard. Besides, when was the last time you saw a GigE PHY that supported Half-Duplex? Autonegotiation on GigE is more about flow-control settings than duplex settings. I assume the situation with 10GE is similar. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
