Hi

Are you seeing drop when you reach the vip?
I remember there was a bug. Can you upgrade your ios release which is old by the way and test it again?

thanks your reply

but i can't upgrade and test again

could you share your knowledge about like IOS version or symptom?

Hi,

What is HSRP status while you faced packet drop? is Physical interface IP addresses are also facing packet drop?

Share the show commands output. 

I know it was an issue in 16.1.x (something) version that when pinging HSRP address configured on the switch, intermittent packet loss can be observed. The issue is not observed when the physical address is being pinged.

I checked the BUG of 3.3(5)SE same like CSCUX39091

thanks~
