Description

Ingress QOS settings that worked in Stream 2026.02 fail to commit in Stream 2026.03.
(Note, these also *do* work in recent nightly builds.)

Here are the configuration commands:

set qos policy shaper INGRESS-SHAPING bandwidth '400mbit'
set qos policy shaper INGRESS-SHAPING default bandwidth '400mbit'
set qos policy shaper INGRESS-SHAPING default burst '15k'
set qos policy shaper INGRESS-SHAPING default queue-limit '1024'
set qos policy shaper INGRESS-SHAPING default queue-type 'fq-codel'

commit

set qos interface ifb0 egress 'INGRESS-SHAPING'
set interfaces ethernet eth0 redirect 'ifb0'
set interfaces input ifb0

commit

Here is the error message I get in Stream 2026.03:

[ interfaces ethernet eth0 ]
Can not use QoS together with mirror/redirect!
[[interfaces ethernet eth0]] failed
[ qos ]
dependent interfaces_ethernet_eth0: Can not use QoS together with

c-po closed this task as a duplicate of T8413: redirect/QoS: Issue in duplex shaping (redirect to input interface).

This is a duplicate which has been fixed in 1.5.0 LTS and also rolling. A subsequent fix will be present in the next stream release, too.
