Hi , We have created 19 vfs per interface on the host side.
cat /sys/class/net/eth2/device/sriov_numvfs 19 cat /sys/class/net/eth1/device/sriov_numvfs 19 ethtool -i eth2 driver: ixgbe version: 4.4.0-k firmware-version: 0x80000843 expansion-rom-version: bus-info: 0000:09:00.1 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: no kernel version : 4.9.249 and x86_64 architecture. We launch 18 pods and each pod will have 2 interfaces eth1 and eth2 mapped from these 38 virtual sriov interfaces. Inside each pod , we are creating vlans from the range[2 to 4094], when this creation is happening parallelly on all the pods , we see that vlans creation is failing randomly on all the pods with RTNETLINK answers: Permission denied Error. command used to create the vlan in all the 18 pods is ip link add link eth2 name mPlaneVlanX type vlan id X -> X is range(2.4094) Could you please let us know if there are any limitations with the numbers of vlans that can be created on the VF interfaces, or is it any known issue ? Could you please help me on this. Regards, Rajesh.
