Hi
We need to update DSCP value on gtp output traffic (inside and outside of
the tunnel too ).
I'm creating GTP tunnel :
...
vppctl set in state GigabitEthernet0/9/0 up
vppctl create sub-interfaces GigabitEthernet0/9/0 5 dot1q 100 exact-match
vppctl set interface state GigabitEthernet0/9/0.5 up
vppctl set int ip address GigabitEthernet0/9/0.5 22.22.2.2/24
vppctl create gtpu tunnel src 22.22.2.2 dst 22.22.2.4 teid 13 tteid 14
encap-vrf-id 0 decap-next ip4
vppctl set interface ip table gtpu_tunnel0 22
vppctl set in state gtpu_tunnel0 up
vppctl set int ip address gtpu_tunnel0 50.50.50.1/24
and I tried to mark packet on gtp interface :
vppctl qos egress map id 0 [ip][0]=30
vppctl qos egress map id 1 [ip][1]=31
vppctl qos mark ext gtpu_tunnel0 id 0
vppctl qos mark ext GigabitEthernet0/9/0.5 id 1
Example from Trace :
04:16:56:227608: ip4-qos-mark
source:ext qos:30 used:no
04:16:56:227611: gtpu4-encap
GTPU encap to gtpu_tunnel0 tteid 14
Result is that packets are not updated . Is QOS mark feature supported on
GTP interface and on sub-interfaces ? Can you advise me how to do it?
Martin
