Hello,
I'm currently working with Ryu and pica8 switches, the working topology can be appreciated in the picture: [cid:f20c714b-3461-4cf9-a454-b445b7746302] In the internal switch, the ports 2 and 1 are patch interfaces. In transport-switches the ports 1 and 2 are pica8 physical interfaces (i.e. "ge-1/1/x") while the interfaces going towards the internal switches (i.e. ports 3 and 4) are patch interfaces. Packets originate from host towards port 1 in transport-switch-1 and is forwarded to internal switch using port 4. Internal switch sends the packet back to transport-switch-1 using port 1. The main issue is that in transport-switch-1 there is a flow for packets entering in port 3 to be tagged with a 1234 vlan tag and forwarded on port 2, towards transport-switch-2. The rule looks like the following: flow_id=4448, cookie=0x0, duration=1.584s, table=1, n_packets=n/a, n_bytes=0, priority=32770,in_port=3 actions=push_vlan:0x8100,set_field:1234->vlan_vid,output:2 Incoming packets in interface 3 are successfully forwarded towards transport-switch-2, but there is no vlan added. In the beginning I thought the problem is occurring because of the patch interfaces, but I replaced port 1 in internal switch and port 3 in transport-switch-1 with pica8 physical interfaces but the problem persists. I would like to kindly ask you to help with this situation, I've been stuck for a couple of days. Thank you. Best regards, Felipe Rodriguez
