Hi I've used following commands to span packets of vlan sub_interface to a tap interface, but nothing captured on tap interface in Linux.
vpp_api_test> create_vlan_subif GigabitEthernet3/0/0 vlan 2100 vppctl> set interface state GigabitEthernet3/0/0 up set interface state GigabitEthernet3/0/0.2100 up set interface state GigabitEthernetb/0/0 up set interface ip address GigabitEthernet3/0/0.2100 192.168.111.1/24 set interface ip address GigabitEthernetb/0/0 192.168.222.1/24 tap connect test set interface state tapcli-0 up set interface span GigabitEthernet3/0/0.2100 both destination tapcli-0 In the bash: #> tcpdump -nn -e -i test Do you have any idea? Cheers, Berna
