标记接口没有接收数据包？

69我的接口上有一个 VLAN ID，enp101s0f0但是没有接收到任何数据包：

enp101s0f0.69: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
    inet 10.15.2.5  netmask 255.255.255.248  broadcast 10.15.2.7
    inet6 fe80::20f:53ff:fe56:2390  prefixlen 64  scopeid 0x20<link>
    ether 00:0f:53:56:23:90  txqueuelen 1000  (Ethernet)
    RX packets 0  bytes 0 (0.0 B)

但是未标记的接口正在接收带有 VLAN ID 标记的数据包69：

enp101s0f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::20f:53ff:fe56:2390  prefixlen 64  scopeid 0x20<link>
        ether 00:0f:53:56:23:90  txqueuelen 1000  (Ethernet)
        RX packets 5814204  bytes 485470187 (462.9 MiB)

如图所示tcpdump：

[root@box-04 ~]# tcpdump -i enp101s0f0 -nn -e vlan
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on enp101s0f0, link-type EN10MB (Ethernet), capture size 262144 bytes

我认为路由表设置正确：

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         10.15.0.1       0.0.0.0         UG    0      0        0 eno1
10.15.0.0       0.0.0.0         255.255.255.0   U     0      0        0 eno1
10.15.2.0       0.0.0.0         255.255.255.248 U     0      0        0 enp101s0f0.69

这可能是什么问题？

ip -s -s -d link show dev这两个接口的情况如下：

[root@box-04 ~]# ip -s -s -d link show dev enp101s0f0

从输出的第三行可以看出ip -s -s -d link show dev enp101s0f0.69，此接口的 vlan id 是698， 不是69。所以，这只是一个配置错误或打字错误。
