Hello all, I have network whose architecture is as shown below. As there are loops in the network ,I'm running STP on the controller which is RYU. But the problem is that even though the openvswitches receive the bpdu configuration packets,they are being disabled. Also the openvswitches are running on three different pc's and not on mininet. When the same topology is run on mininet, everything works flawlessy.
c0(Ryu) | ------------switch-------------- | (normal switch) | | | | | -------- ovs1----------- | | | | | Host1--------Ovs2 ---------------------- ovs3----host2 The ovs version is 2.3.1. Does ovs just drop bpdu packets when stp is disabled? I have also modified the ports to receive-stp. I'm also attaching the port data and the bridge configuration : ovs-vsctl list bridge _uuid : 1e4df0df-fb73-4f49-8311-9a0daa88a84f controller : [7af3325d-754a-4bf7-9949-f6b15d5c095e] datapath_id : "00000010f33acafb" datapath_type : "" external_ids : {} fail_mode : secure flood_vlans : [] flow_tables : {} ipfix : [] mirrors : [] name : "s1" netflow : [] other_config : {disable-in-band="true"} ports : [49c14788-b49e-4c39-ba7b-e3a24c11abbd, b9542e30-5bd0-49c0-b6c3-b0556e33f988, eacc4c3d-a10d-4ded-905f-5976ce42d4a7] protocols : ["OpenFlow13"] sflow : [] status : {} stp_enable : false ovs-ofctl -O openFlow13 dump-flows s1 OFPST_FLOW reply (OF1.3) (xid=0x2): cookie=0x0, duration=2793.242s, table=0, n_packets=1046, n_bytes=62760, priority=65535,dl_dst=01:80:c2:00:00:0e actions=CONTROLLER:65535 cookie=0x0, duration=9125.242s, table=0, n_packets=288482, n_bytes=17308920, priority=65535,dl_dst=01:80:c2:00:00:00 actions=CONTROLLER:65535 cookie=0x0, duration=2793.439s, table=0, n_packets=2014, n_bytes=474412, priority=0 actions=CONTROLLER:65535 cookie=0x0, duration=50.026s, table=0, n_packets=0, n_bytes=0, priority=65534,in_port=3 actions=drop cookie=0x0, duration=40.161s, table=0, n_packets=0, n_bytes=0, priority=65534,in_port=1 actions=drop cookie=0x0, duration=601019.436s, table=0, n_packets=0, n_bytes=0, priority=65535,dl_dst=01:80:c2:00:00:0e,dl_type=0x88cc actions=CONTROLLER:65535 ovs-ofctl -O openFlow13 dump-ports-desc s1 OFPST_PORT_DESC reply (OF1.3) (xid=0x2): 1(p1p1): addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN state: 0 current: 1GB-FD COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG speed: 1000 Mbps now, 1000 Mbps max 3(p4p1): addr:a0:36:9f:44:3f:2c config: NO_PACKET_IN state: 0 current: 1GB-FD COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG AUTO_PAUSE supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG AUTO_PAUSE speed: 1000 Mbps now, 1000 Mbps max LOCAL(s1): addr:00:10:f3:3a:ca:fb config: 0 state: 0 speed: 0 Mbps now, 0 Mbps max root@cocosdem3:/home/cocos# ovs-ofctl snoop s1 OFPT_PORT_STATUS (OF1.3) (xid=0x0): MOD: 1(p1p1): addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN state: 0 current: 1GB-FD COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG speed: 1000 Mbps now, 1000 Mbps max OFPT_PORT_MOD (OF1.3) (xid=0x1868f4ee):port: 1: addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN mask: PORT_DOWN NO_RECV NO_FWD NO_PACKET_IN advertise: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG OFPT_FLOW_MOD (OF1.3) (xid=0x1868f4ef): ADD priority=65534,in_port=1 out_port:0 actions=drop OFPT_PACKET_OUT (OF1.3) (xid=0x1868f4f0): in_port=CONTROLLER actions=output:1 data_len=52 metadata=0,in_port=0,vlan_tci=0x0000,dl_src=00:10:f3:3a:ca:fb,dl_dst=01:80:c2:00:00:0e,dl_type=0x05ff OFPT_PORT_STATUS (OF1.3) (xid=0x0): MOD: 1(p1p1): addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN state: LINK_DOWN current: COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG speed: 0 Mbps now, 1000 Mbps max OFPT_PORT_STATUS (OF1.3) (xid=0x0): MOD: 1(p1p1): addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN state: 0 current: 1GB-FD COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG speed: 1000 Mbps now, 1000 Mbps max OFPT_PORT_MOD (OF1.3) (xid=0x1868f4f1):port: 1: addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN mask: PORT_DOWN NO_RECV NO_FWD NO_PACKET_IN advertise: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG OFPT_FLOW_MOD (OF1.3) (xid=0x1868f4f2): ADD priority=65534,in_port=1 out_port:0 actions=drop OFPT_PACKET_OUT (OF1.3) (xid=0x1868f4f3): in_port=CONTROLLER actions=output:1 data_len=52 metadata=0,in_port=0,vlan_tci=0x0000,dl_src=00:10:f3:3a:ca:fb,dl_dst=01:80:c2:00:00:0e,dl_type=0x05ff OFPT_PORT_STATUS (OF1.3) (xid=0x0): MOD: 1(p1p1): addr:00:10:f3:3a:ca:fb config: NO_PACKET_IN state: LINK_DOWN current: COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG speed: 0 Mbps now, 1000 Mbps max OFPT_PORT_STATUS (OF1.3) (xid=0x0): MOD: 1(p1p1): addr:00:10:f3:3a:ca:fb config: NO_PACKET_In state: 0 If anyone has any insights please let me know.
