From 7ed018cddf88ac1c5a92f71fa5e421e66d259bc0 Mon Sep 17 00:00:00 2001 From: Ross Brattain Date: Wed, 18 Oct 2017 18:14:13 -0700 Subject: NSB: fix trex config to use dpdk port number From some reason Heat/Neutron is now creating interfaces such that xe0 and xe1 are swapped. xe0 fa:16:3e:38:c7:66 0000:00:05.0 xe1 fa:16:3e:2f:f3:e2 0000:00:03.0 this causes the DPDK port numbering to be swapped. xe0 is DPDK port 1 because it has higher PCI address xe1 is DPDK port 0 because it has lower PCI address. The VNF is configured correctly because it uses DPDK port numbers, whereas TRex was using interface list ordering. Modify trex_cfg.yaml to use DPDK port ordering. This also requires running generate_cfg() after setup() in instantiate() +------------------------------------+-------------------+------------------------------+--------+ | Name | MAC Address | Fixed IP Addresses | Status | +------------------------------------+-------------------+------------------------------+--------+ | vnf_0.yardstick-af5ccb47-xe0-port | fa:16:3e:66:a5:e4 | ip_address='10.1.0.7', | ACTIVE | | vnf_0.yardstick-af5ccb47-mgmt-port | fa:16:3e:fa:98:fe | ip_address='10.0.1.10', | ACTIVE | | tg_0.yardstick-af5ccb47-xe1-port | fa:16:3e:2f:f3:e2 | ip_address='10.1.1.9', | ACTIVE | | vnf_0.yardstick-af5ccb47-xe1-port | fa:16:3e:f3:1d:f5 | ip_address='10.1.1.4', | ACTIVE | | | fa:16:3e:e3:8c:65 | ip_address='10.0.1.1', | ACTIVE | | | fa:16:3e:ff:d1:b7 | ip_address='11.191.14.110', | N/A | | tg_0.yardstick-af5ccb47-xe0-port | fa:16:3e:38:c7:66 | ip_address='10.1.0.8', | ACTIVE | | | fa:16:3e:ff:53:5f | ip_address='11.191.14.101', | DOWN | | | fa:16:3e:23:5d:2c | ip_address='10.0.1.2', | ACTIVE | | tg_0.yardstick-af5ccb47-mgmt-port | fa:16:3e:7a:df:4e | ip_address='10.0.1.5', | ACTIVE | | | fa:16:3e:22:65:36 | ip_address='11.191.14.109', | N/A | +------------------------------------+-------------------+------------------------------+--------+ /sys/devices/pci0000:00/0000:00:03.0/virtio0/net/ens3/address:fa:16:3e:2f:f3:e2 /sys/devices/pci0000:00/0000:00:05.0/virtio2/net/ens5/address:fa:16:3e:38:c7:66 Change-Id: Iaef2c7d9a5af7f45bd805a8ad6ee545ce0495cb1 Signed-off-by: Ross Brattain --- .../network_services/vnf_generic/vnf/sample_vnf.py | 3 ++- .../network_services/vnf_generic/vnf/tg_trex.py | 25 ++++++++++++---------- 2 files changed, 16 insertions(+), 12 deletions(-) diff --git a/yardstick/network_services/vnf_generic/vnf/sample_vnf.py b/yardstick/network_services/vnf_generic/vnf/sample_vnf.py index b5cf03477..08ec44f65 100644 --- a/yardstick/network_services/vnf_generic/vnf/sample_vnf.py +++ b/yardstick/network_services/vnf_generic/vnf/sample_vnf.py @@ -924,8 +924,9 @@ class SampleVNFTrafficGen(GenericTrafficGen): def instantiate(self, scenario_cfg, context_cfg): self.scenario_helper.scenario_cfg = scenario_cfg - self.resource_helper.generate_cfg() self.resource_helper.setup() + # must generate_cfg after DPDK bind because we need port number + self.resource_helper.generate_cfg() LOG.info("Starting %s server...", self.APP_NAME) name = "{}-{}-{}".format(self.name, self.APP_NAME, os.getpid()) diff --git a/yardstick/network_services/vnf_generic/vnf/tg_trex.py b/yardstick/network_services/vnf_generic/vnf/tg_trex.py index fe435f63e..458f1b844 100644 --- a/yardstick/network_services/vnf_generic/vnf/tg_trex.py +++ b/yardstick/network_services/vnf_generic/vnf/tg_trex.py @@ -49,30 +49,33 @@ class TrexResourceHelper(ClientResourceHelper): SYNC_PORT = 4501 def generate_cfg(self): - ext_intf = self.vnfd_helper.interfaces + port_names = self.vnfd_helper.port_pairs.all_ports vpci_list = [] port_list = [] - trex_cfg = { - 'interfaces': vpci_list, - 'port_info': port_list, - "port_limit": len(ext_intf), - "version": '2', - } - cfg_file = [trex_cfg] - for interface in ext_intf: + port_nums = sorted(self.vnfd_helper.port_nums(port_names)) + for port_num in port_nums: + interface = self.vnfd_helper.find_interface_by_port(port_num) virtual_interface = interface['virtual-interface'] - vpci_list.append(virtual_interface["vpci"]) dst_mac = virtual_interface["dst_mac"] + # why skip?, ordering is based on DPDK port number so we can't skip if not dst_mac: continue - + # TRex ports must be in DPDK port number, so order of append matters + vpci_list.append(virtual_interface["vpci"]) local_mac = virtual_interface["local_mac"] port_list.append({ "src_mac": mac_address_to_hex_list(local_mac), "dest_mac": mac_address_to_hex_list(dst_mac), }) + trex_cfg = { + 'interfaces': vpci_list, + 'port_info': port_list, + "port_limit": len(port_names), + "version": '2', + } + cfg_file = [trex_cfg] cfg_str = yaml.safe_dump(cfg_file, default_flow_style=False, explicit_start=True) self.ssh_helper.upload_config_file(os.path.basename(self.CONF_FILE), cfg_str) -- cgit 1.2.3-korg
