thanks for the answer.
It's 10 G interface.
If I put:
qfx# set interfaces xe-0/0/46 unit 400 family inet address 10.10.10.1/24
{master:0}[edit]
qfx# commit
[edit interfaces xe-0/0/46]
'unit 400'
Only unit 0 is valid for this encapsulation
I am trying to replicate the configuration from another device, is configured like that:
qfx2> show configuration | display set | match 0/0/50
set interfaces xe-0/0/50 disable
set interfaces xe-0/0/50:0 vlan-tagging
set interfaces xe-0/0/50:0 encapsulation flexible-ethernet-services
