[j-nsp] MX204 port 1G

[Richard McGovern]

Correct.  Unlike EX/QFX where for 1/10 capable interfaces the name will match the insert Optic.  1G Optic shows as ge, 10G Optic shows as xe.  Both ge/xe names allowed.

For MX/SRX (and I assume PTX and maybe ACX - don't much deal with those products ) xe is ONLY name allowed, and is used to indicate the interface is 10G capable.  For show interface info, the interface will show the correct speed.

NOTE: Please don't ask me the why.  Tried to fight that battle, this will NOT be changed.

As for William original question why are you hard coding 1G in the config, and setting 10G in the HW (chassis stanza)?  From initial look, that is first place to look.  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.

Did you have issue with auto for interface, which is default setting?
