Hello, I have some scenario - I need to connect two switches over 40G ports from Juniper EX4300-24P (Rev.A). Can I use four ports in backside EX4300 for this or this 40G  ports only for VCP?
If I can use it, how I can configure this ports? Because in the configuration I found only 10G interfaces xe-0/0/0. (firmware version 18.3R1.9)

Correct me if I'm wrong: I need to create  et interface  (40G interface)like this?:

set interfaces et-0/0/0 unit 0 family ethernet-switching interface-mode trunk VLAN members all

Re: Configure 40G ports EX4300-24P

By default, the QSFP+/40GE ports on EX4300 are configured for VCP.   You need to delete this setting and then configure ports as standard Ethernet for what you want to do.

 

Google "EX4300 vcp ports" and you'll get many hits for what to do.

 

Good luck
