Ingress qdisc does not work anymore in 1.3-rolling-202101 snapshot
Closed, ResolvedPublicBUG


here is brief configuration that does not work in 1.3-rolling-202101 snapshot

interfaces {

hw-id XX:XX:XX:XX:XX:20
vif 60 {
  description INET-DMZ
vif 408 {
  description BEELINE-INET-BGP
  firewall {
    local {
      name IN
  redirect ifb408
  traffic-policy {
vif 1099 {
  description Mgmt
  vrf Mgmt-vrf
input ifb408 {
 traffic-policy {


  1. input traffic does not redirected to desired ifb interface. /opt/vyatta/sbin/ terminates with error at line 344.
  2. as a consequence vlans at eth0 do not initialized during boot.

i tried to reproduce commands manually
zotov@ttylog:~$ sudo tc qdisc del dev eth0 ingress
zotov@ttylog:~$ sudo /sbin/tc qdisc add dev $dev handle fffe: ingress
zotov@ttylog:~$ /sbin/tc filter add dev $dev parent fffe: protocol all prio 10 u32 match u32 0 0 flowid 1:1 action mirred egress redirect dev ifb0
Error: Parent Qdisc doesn't exists.
We have an error talking to the kernel, -1

changing fffe to ffff in eliminated the problem.

@Dmitry @a952637635. It seems that, I changed the handle address to avoid conflict. I don't know if it will conflict

Viacheslav changed Is it a breaking change? from Unspecified (possibly destroys the router) to Perfectly compatible.
Viacheslav added a project: VyOS 1.3 Equuleus.
Viacheslav added a project: VyOS 1.4 Sagitta.

Now the problem should be solved
