When I removed "speed 10g" from chassis section
admin@mx1> show configuration |compare rollback 1
[edit chassis fpc 0 pic 1]
- port 4 {
- speed 10g;
- }
and bounced FPC 0, interface not found.
admin@mx1> show interfaces xe-0/1/4
error: device xe-0/1/4 not found
In documentation we can read that 10g is default. It’s seems not.
When I removed "speed 1G” from gigether-options section, interface is found,
but is DOWN.
Any Idea? :)
