By default, Gigabit Ethernet interfaces (both built-in and PIMs) for J-series Services Routers autonegotiate whether to operate at 10 megabits per second (Mbps), 100 Mbps, or 1000 Mbps.
To configure a J-series Gigabit Ethernet interface to operate at 10 Mbps, 100 Mbps, or 1000 Mbps, include the speed statement at the [edit interfaces ge-pim/0/port] hierarchy level:
- [edit interfaces ge-pim/0/port]
-
speed (10m | 100m | 1g);
