The problem was happened in vlan mp-ify.
I fixed this problem by the following patch in my environment.
Could you apply the patch and check it?

Hello,
The interface counters of vlan interface do not count:
bash-4.4# ifconfig -v vlan8
vlan8: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=7ff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx>
capabilities=7ff80<TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Rx>
capabilities=7ff80<TCP6CSUM_Tx,UDP6CSUM_Rx,UDP6CSUM_Tx,TSO6>
enabled=0
vlan: 8 parent: ixg0
address: a0:36:9f:d4:3c:08
input: 1966263 packets, 273676300 bytes, 66058 multicasts
output: 1238957 packets, 0 bytes
inet6 fe80::a236:9fff:fed4:3c08%vlan8/64 flags 0x0 scopeid 0x1a
inet6 xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx flags 0x0
The output byte counter shows 0. With netbsd-7 all worked fine.
So it is not longer possible to record traffic data via snmp.
I test s-yamaguchi's patch and minor fixes which I received locally.
# He is my co-worker :)
The patch fixes the problem correctly, so I commit that as if_vlan.c:r1.99.
I will send pullup request to netbsd-8 branch. Could you retry after
pulled up?
Thanks,
