Sflow - egress sampling

Hi,

I realized sflow send only the ingress traffic to my collector, not the egress traffic

I have this "issue" on my ERS4950 and VSP (7200, 7400, 8400). Is this a normal behaviour or did I forget something in my config ?

And if it's a limitation, can I hope any improvment on a next firmware on switch model ?

On ERS :

sflow enable
sflow collector 1 address x.x.x.x owner yyy port 9999
interface Ethernet ALL
sflow port 1 sampling-rate ingress 4096
sflow port 1 sampling-rate egress 4096
sflow port 2 sampling-rate ingress 4096
sflow port 2 sampling-rate egress 4096
sflow port 1-2 collector 1

On VSP :

sflow agent-ip z.z.z.z
sflow enable
sflow collector 1 address x.x.x.x
sflow collector 1 owner yyy
sflow collector 1 port 9999

interface GigabitEthernet 1/1

sflow sampling-rate 1024
sflow collector 1

Thanks

Quentin
