Nexus 3548 subinterface statistics missing

[raitech12]

I am trying to get statistics for subinterfaces on a Cisco Nexus3500 C3548P-10GX switch.

The subinterface is configured for a port channel as shown below.

interface port-channel3.1802
  encapsulation dot1q 1802
  ip address 192.168.1.165/30

There is nothing shown as statistics for VLAN or subinterface.

NEXUS(config)# sh interface port-channel3.1802
port-channel3.1802 is up
admin state is up,, [parent interface is port-channel3]
  Hardware: Port-Channel, address: xxxx.xxxx.7641 (bia xxxx.xxxx.7608)
  Description: vlan for internet
  Internet Address is 192.168.1.165/30

  Encapsulation 802.1Q Virtual LAN, Vlan ID 1802, medium is broadcast
  Auto-mdix is turned off
  Switchport monitor is off
  EtherType is 0x8100

NEXUS(config)# sh interface vlan 1802
Vlan1802 is up, line protocol is up, autostate enabled

  Last clearing of "show interface" counters never

For other interfaces, I have these statistics:

show version:

Software
  BIOS: version 5.3.1
  NXOS: version 7.0(3)I7(7)
  BIOS compile time:  06/04/2019
  NXOS image file is: bootflash:///nxos.7.0.3.I7.7.bin
  NXOS compile time:  8/28/2019 16:00:00 [08/29/2019 00:41:42]

Is there any way to enable statistics for subinterfaces?
