3 Ethernet interface configuration
Nortel Secure Router 8000 Series
Configuration - LAN Access and MAN Access
This command configures the speed of the FE electrical interface.
• Run:
speed { 100 | negotiation }
This command configures the speed of the GE electrical interface on the Secure Router
8012 Routing Process Unit (RPU).
CQ NOTE
• The default speed for FE and GE electrical interfaces is autonegotiation. You can change the speed,
but it must be consistent with that of the peer device.
• A speed of 1000 Mbit/s and half-duplex mode cannot be configured simultaneously on a GE
electrical interface.
• You do not need to configure the speed of an optical interface.
