From the customer:
Dear VyOS team,
we wanted to test the new ipfix feature for VPP on VyOS rolling. Unfortunately we encountered a bug. Once you set a bond interface as direction and flow-variant like this:
```
set vpp ipfix active-timeout ‘20’
set vpp ipfix collector 185.27.180.68 path-mtu ‘1450’
set vpp ipfix collector 185.27.180.68 port ‘2100’
set vpp ipfix collector 185.27.180.68 source-address ‘192.168.181.209’
set vpp ipfix collector 185.27.180.68 template-interval ‘20’
set vpp ipfix flowprobe-record ‘l3’
set vpp ipfix inactive-timeout ‘120’
set vpp ipfix interface bond1 direction ‘both’
set vpp ipfix interface bond1 flow-variant ‘ipv4’
```
the bond1 interface will not be translated to VPP interface BondEthernet1 and therefore it does not add the feature inside VPP.
It should look like this:
```
#vppctl show flowprobe feature
BondEthernet1 ip4 rx tx
```
but instead it shows nothing. Only if you use a single ethernet interface `set vpp ipfix interface eth1 direction both` it will show up (I guess because kernel interface eth1 is named the same as in VPP interface naming). So the mapping seems to be not correct. Adding it manually via sudo vppctl flowprobe feature add-del BondEthernet1 ip4 both works as intended.
This is our VPP config:
```
set vpp interfaces bonding bond1 hash-policy ‘layer3+4’
set vpp interfaces bonding bond1 kernel-interface ‘vpptun0’
set vpp interfaces bonding bond1 member interface ‘eth4’
set vpp interfaces bonding bond1 member interface ‘eth5’
set vpp interfaces bonding bond1 mode ‘802.3ad’
set vpp kernel-interfaces vpptun0 address ‘192.168.181.209/25’
set vpp kernel-interfaces vpptun0 mtu ‘1500’
set vpp settings buffers buffers-per-numa ‘65536’
set vpp settings cpu main-core ‘0’
set vpp settings cpu workers ‘4’
set vpp settings interface eth4 dpdk-options num-rx-queues ‘4’
set vpp settings interface eth4 driver ‘dpdk’
set vpp settings interface eth5 dpdk-options num-rx-queues ‘4’
set vpp settings interface eth5 driver ‘dpdk’
set vpp settings lcp netlink rx-buffer-size ‘536870912’
set vpp settings memory main-heap-size ‘4G’
set vpp settings statseg size ‘256M’
