Hoi, I have seen that message, but it is not related to the Linux CP plugin, and it seems benign -- that is to say, Linux CP and VPP work just fine even though the error is emitted. Without Linux CP enabled, the same message appears when adding an IP address to a sub-int. I didn't look in to it very long, but the error is emitted in src/vnet/interface.c:1583 for function vnet_hw_interface_add_del_mac_address() which occurs only in a few places:
src/plugins/lldp/lldp_cli.c: vnet_hw_interface_add_del_mac_address (lm->vnet_main, src/plugins/lldp/lldp_cli.c: vnet_hw_interface_add_del_mac_address (lm->vnet_main, src/plugins/vrrp/vrrp.c: error = vnet_hw_interface_add_del_mac_address src/vnet/interface_api.c: error = vnet_hw_interface_add_del_mac_address (vnm, hi->hw_if_index, src/vnet/mfib/mfib_itf.c: vnet_hw_interface_add_del_mac_address (vnet_get_main(), src/vnet/bonding/device.c: error = vnet_hw_interface_add_del_mac_address (vnm, s_hi->hw_if_index, src/vnet/bonding/device.c: vnet_hw_interface_add_del_mac_address (vnm, s_hi->hw_if_index, src/vnet/bonding/cli.c: vnet_hw_interface_add_del_mac_address (vnm, s_hwif->hw_if_index, src/vnet/interface_cli.c: vnet_hw_interface_add_del_mac_address (vnm, si->hw_if_index, mac, is_add); If you're curious, you could take a look at these call sites. One other place you might look is ip6_add_del_interface_address() and ip4_add_del_interface_address() which are the functions that get called when you issue the CLI 'set interface ip address' command. But it would also be okay to ignore the error for now -- maybe others have a recollection of how vnet_hw_interface_add_del_mac_address() does its business. groet, Pim On Mon, Jan 17, 2022 at 9:27 AM Petr Boltík <petr.bol...@gmail.com> wrote: > Hello, > > did you notice this error message from systemctl? > > Message from systemctl status vpp-dataplane: > vnet[2526]: interface: hw_add_del_mac_address: > vnet_hw_interface_add_del_mac_address: Secondary MAC Addresses not > supported for interface index 0 > Jan 17 03:16:05 stredni vnet[2526]: interface: hw_add_del_mac_address: > vnet_hw_interface_add_del_mac_address: Secondary MAC Addresses not > supported for interface index 0 > > Vpp run in separated netns.
