The Gigabit Ethernet ports on the router have the capacity to work as a 1 or 10-Gigabit
Ethernet interface, depending on the type of small form-factor pluggable (SFP)
transceiver inserted. When you insert an SFP+ transceiver, the interface works at the
10-Gigabit speed. When you insert an SFP transceiver, the interface works at the 1-Gigabit
speed. Configuration is not required because the speed is determined automatically
based on the type of inserted SFP transceiver. The dual-speed interface is automatically
created with the xe prefix, for example, xe-4/0/0.
The same configuration statements are used for both speeds and CoS parameters are
scaled as a percentage of the port speed. To configure a dual-speed Gigabit Ethernet
interface, include the interface xe-fpc/pic/port statement at the [edit interfaces] hierarchy
level. To display the interface speed and other details, issue the show interfaces command.
NOTE: You need to use industrial grade of SFP below 0dC for ACX 1100 and
ACX 2100 boards.
