[j-nsp] Sflow on non-zero units for ELS style switches (EX4300)

[Paul S.]

Hi,

In the past, I used to deploy similar configs on non-ELS switches, and 
they mostly worked just fine with sflow.

sw# show interfaces xe-0/2/0
ether-options {
     802.3ad ae1;
}

{master:0}[edit]
sw# show interfaces ae1
description "Trunked to <>";
vlan-tagging;
aggregated-ether-options {
     minimum-links 1;
     link-speed 10g;
}
unit 20 {
     vlan-id 20;
     family inet {
         address <>;

     }
     family inet6 {
         address <>;

     }
}

Nothing but a port that's been trunked through another L2 switch.

You could turn on sflow for this using `set protocols sflow interface 
xe-0/2/0.20` and that would be the end of it.

Now though, it says that enabling sflow on any other unit than 0 is "not 
allowed."

[edit protocols sflow]
   'interfaces xe-0/2/0.20'
     sFlow can only be run on .0 interfaces
error: configuration check-out failed

I'm running the Juniper recommended version of code on this one.

Model: ex4300-48t
JUNOS EX  Software Suite [13.2X51-D30.4]

Having it on unit 0 produces no sflow datagrams (as expected, to be honest)

Collector         Udp-port    No. of samples
  address
10.100.10.100   6343        0

What are my options to make this switch work with the current way it is 
set up, and have sflow exporting enabled?

Thanks for reading!
