Re: [vpp-dev] Ping reply packets reaching vnet interface with correct vlan tags are not seen in VPP for VLAN interface.

Hi, We have an observation that if we change the device type of our interface from virtio to e1000 or we keep device type virtio as is and set promiscuous on for the parent interface of vlan interface, we could get our end to end packet flow working with VLAN interfaces configured, for both

Hi, We are trying to debug this issue and we have a question regarding this that If the packet is seen on the vnet interface of the VM hosting VPP, and not seen in VPP packet trace, can we debug something at VPP level? Thanks and Regards, Chinmaya Agarwal. -=-=-=-=-=-=-=-=-=-=-=- Links: You

Hi, After applying IP and link state from linux (as per my previous post), we actually see IP and state being copied to VPP as well. vpp# show interface address GigabitEthernet0/8/0 (up): GigabitEthernet0/8/0.1400 (up): L3 24.24.10.101/24 L3 2001:24:10:a111::101/64 local0 (dn): tap1 (up):

Hoi, You have to (for now) apply the IP and link state both in Linux and in VPP by hand - they will not copy back and forth until Linux CP is fully committed. if you type 'show interface address' in VPP, you are not likely to see the addresses show up there, right? So add a bit of vppctl set

Hi, We have two VMs running on Centos 8.4 and base server running on Centos 7.8. VM1 is running VPP(v21.06) and VM2 is a normal linux machine. VM1 is connected to VM2 on GigabitEthernet0/8/0 interface. We created a VLAN interface (with VLAN id 1400) on both the VMs and we are trying to ping
