vpn interface speed—Set the speed of the interface. Configure the interface speed, for use when the remote end of the connection does not support autonegotiation.

On all vEdge router models, all interfaces support 1-Gigabit Ethernet SFPs. These SFPs can either be copper or fiber. For fiber SFPs, the supported speed is 1 Gbps full duplex. For copper SFPs, the supported speeds are 10/100/1000 Mbps and half/full duplex. By default, the router autonegotiates the speed and duplex values for the interfaces.

To use a fixed speed and duplex configuration for interfaces that do not support autonegotiation, you must disable autonegotiation and then use the speed and duplex commands to set the appropriate interface link characteristics.
