[QFX] Commit error occurs when sflow is enabled on Layer 3 VLAN-tagged interface



Article ID: KB36076 KB Last Updated: 11 Jul 2020Version: 1.0

This article describes the behavior of sflow when it is enabled on Layer 3 VLAN-tagged interface. This is applicable to QFX10k only.


When sflow is enabled on Layer 3 VLAN-tagged interface, the following commit error occurs:

root@QFX10k# show protocols sflow
interfaces et-0/0/2.1;
interfaces et-0/0/2.2;
root@QFX10k# commit
[edit protocols sflow]
'interfaces et-0/0/2.2'
only one ifl is allowed  <---
error: configuration check-out failed

QFX10k is supports sflow on L3 VLAN-tagged interfaces, but does not support enabling sflow on multiple sub interfaces on the same port.


Please configure sflow on one of the sub interfaces for Layer 3 VLAN-tagged interface. Then sflow will be enabled for other sub interfaces as well.

Note: You cannot enable sflow on one of sub interfaces only.
