Naming the Interfaces
vMX supports the following interface types:
Gigabit Ethernet (ge)
10-Gigabit Ethernet (xe)
100-Gigabit Ethernet (et)
By default, the interfaces come up as ge interfaces with 1 Gbps bandwidth in the Junos OS configuration. The default port speed values for the interface types are 1 Gbps (ge), 10 Gbps (xe), and 100 Gbps (et). If you do not enable schedulers, the speed is only for display purposes and is not enforced. If you enable schedulers, the transmit rate of the port is limited to the speed unless it is overridden by the shaping rate in the CoS configuration.
To specify the interface types, configure the interface type

hierarchy level.
