Juniper EX9214 Hardware Guide

NOTE: Note the following when you congure rate selectability on an EX9200-12QS line card:
• When you boot the line card:
• If rate selectability is not congured, all ports of the line card operate at the default speed
as four 10-Gigabit Ethernet interfaces.
• If rate selectability is congured with invalid port speeds, all ports for which invalid speeds
were congured operate at the default speed.
• If valid port speeds are congured, the ports operate at the congured speeds.
• When you change an exisng port-speed conguraon, for the conguraon to take eect,
you must do either of the following:
• Reset the PICs to which the congured ports belong, by using the request chassis pic pic-
slot pic-slot-number fpc-slot fpc-slot-number (online | offline) command. Because reseng
the line card takes several minutes and because it aects all the Packet Forwarding
Engines, use this command to apply your conguraon changes quickly.
• Reset the line card
An alarm is generated indicang the change in port-speed conguraon.
• When you change an exisng port-speed conguraon to an invalid port-speed conguraon
and commit the conguraon, an alarm is generated indicang that the port-speed
conguraon is invalid. The port connues to operate at the exisng port speed.
• You cannot congure rate selectability at the PIC level and the port level simultaneously. Error
messages are displayed when you try to commit such conguraons.
• If you congure rate selectability at the port level, logical interfaces are created only on the
congured ports. No logical interfaces are created on the other ports.
