Which is the POS port?
I read the juniper-interface pos, there seems have no introduce of it.
I have a Juniper-EX4200 interfaces picture:
The front:
The back:
There I do not find a interface named POS port, so, who can explain for me?

I really doubt an ethernet switch can do SONET.– Teun VinkCommented Jul 31, 2018 at 14:39

the manual has the POS port configuration.– qg_java_17137Commented Aug 1, 2018 at 4:45

which manual would that be? I can understand if the JunOS manual has it (since some of the other platforms do support SONET), I really doubt the EX series (which is positioned as a datacenter switch) supports this, I don't see SONET, SDH or POS mentioned in the datasheet: juniper.net/assets/us/en/local/pdf/datasheets/1000215-en.pdf– Teun VinkCommented Aug 1, 2018 at 4:55

I think should have a optical fiber convertor.– qg_java_17137Commented Aug 1, 2018 at 6:13

That has nothing to do with POS. The 'network ports' on the front can have fiber ports (SFP), depending on the exact model of EX4200 you have, as you can see on juniper.net/documentation/en_US/release-independent/junos/…– Teun VinkCommented Aug 1, 2018 at 6:18

posis a packet over SONET interface.
In the picture that you are attaching there is not a SONET interface, they look like this:
It's a fiber optics interface able to use SONET as signaling and pos is a definition that permits to transport packets over SONET.
