[j-nsp] MX204 port 1G

[Łukasz Trąbiński]

When I removed "speed 10g" from chassis section


admin at mx1> show configuration |compare rollback 1 
[edit chassis fpc 0 pic 1]
-     port 4 {
-         speed 10g;
-     }

and bounced FPC 0, interface not found.

admin at 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?  :)

BTW, on MX204, neither should needed.  FPC does not need speed setting (default supports 1/10) and auto should work fine at interface config. If you needed fixed speed for working with remote device, then set speed at interface level only.  If you are going to do both, make them equal, although I am guess chassis fpc only has 10G as option.
