NOTE:
•
When you configure the Tri-Rate Ethernet copper interface to operate at
1 Gbps, autonegotiation must be enabled.
•
On ACX Series Universal Access Routers, when the autonegotiation is
disabled, the speed has to be explicitly configured to 10–100 Mbps.
•
On T4000 routers, the auto-negotiation command is ignored for interfaces
other than Gigabit Ethernet.
