I'm having an issue with identifying the traffic load on Vlan interface on my N9k FX2 (specifically C93360YC-FX2).. Show interface Vlan XXX displays with the traffic shown as :- ucast: 0 pkts, 0 bytes. Please can someone explain if this is expected behaviour or not?
Many thanks in advance.

Hi,
Seems like not, due to following bug: https://quickview.cloudapps.cisco.com/quickview/bug/CSCvp32970
Symptom: SVI counters do not work on N9K-C93240YC-FX2 even with "hardware profile svi flex-stats-enable" applied. Known Affected Releases 9.2(3) 9.3(1)

Does vlan xxx have an IP associated with? Is the IP the gateway for a user or server vlan traffic?

Thanks, Reza for the response.
Yes, it is having an IP associated (SVI Interface) and used for establishing an eBGP peering having active traffic flow.
********For reference output state as below************
VlanXXX is up, line protocol is up, autostate enabled
Hardware is EtherSVI, address is XXXXX
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive not supported
ARP type: ARPA
Last clearing of "show interface" counters never
L3 in Switched:
ucast: 0 pkts, 0 bytes : >>> This is the part which concern me at this point

Many thanks.

Hi,
Do you see traffic on the physical interface that is peering BGP? If yes, not seeing traffic on the vlan interface may not be an issue.
