Release Information
Statement introduced in JUNOS Release 9.5.
Description
On MX-series platforms with Combo Line Rate DPCs and Tri-Rate Copper SFPs you can set auto-negotiation of speed. To specify the auto-negotiation speed, use the speed ( < auto | 1Gbps | 100Mbps | 10Mbps> ) statement under the [edit interface ge-/fpc/pic/port] hierarchy level. The < auto> option will attempt to automatically match the rate of the connected interface. To set port speed negotiation to a specific rate, set the port speed to either 1Gbps, 100Mbps, or 10Mbps.

Note: If the negotiated speed and the interface-speed do not match, the link will not be brought up. Half duplex mode is not supported. |
You can disable auto MDI/MDIX using the < no-auto-mdix> statement option under the [edit interface ge-/fpc/pic/port gigether-options] hierarchy level.
Options
-
You can specify the speed as either < auto> (autonegotiate), 1Gbps (1 Gbps), 100Mbps (100 Mbps), or 10Mbps (10 Mbps).
