Hi,
I know this bug is not for Catalyst C9500 and C9300, but I am experiencing the same issue in 17.6.4 and 17.6.5. But it is fine in 17.6.3. Can anyone in TAC test this out and issue a fix? My PCs cannot ping their gateway SVIs if they swap between private VLANs until i recreate the SVI or reboot the switch. No IP Sticky ARP is configured already.
