Configuring Autonegotiation Speed on MX Series Routers
MX Series routers with Combo Line Rate DPCs and Tri-Rate Copper SFPs support
autonegotiation of speed. The autonegotiation specified interface speed is propagated
to CoS, routing protocols, and other system components. Half-duplex mode is not
supported.
To specify the autonegotiation speed, use the

Displaying Autonegotiation Status
To display Gigabit Ethernet interface details, including the autonegotiation status,
use the operational mode command
Table 77 on page 799 and Table 78 on page 801 provide information about the
autonegotiation status on local and remote routers with fiber interfaces. The status
of the link and LED can vary depending on the level of autonegotiation set and the
transmit and receive fiber status.
