In OPNFV we found the following problem when using UCS NIC. The UCS fabric seems to set a VLAN tag on untagged packets. Any thoughts from DPDK and VPP folks would be appreciated. http://dpdk.org/doc/guides-16.07/nics/enic.html https://jira.opnfv.org/browse/APEX-333 It is currently deploying DPDK 16.04 and OVS 2.5.90 I could not find a user accessible setting to do this that would work. The workaround for now we came up with is to set a flow in OVS to strip the tag. https://gerrit.opnfv.org/gerrit/#/c/23315/ Another solution is to set the nic to strip the vlan in rte eth code or write a DPDK "app" to set the nic. http://dpdk.org/doc/guides-16.07/nics/enic.html --TFH -- *Thomas F Herbert* SDN Group Office of Technology *Red Hat*
