After rebooting the Nexus switch have to ping locally in order to make traffic working

Hi Experts

I have Cisco Nexus 3000 configured with VPC domain, port channel and vrrp.

Whenever I reboot the switches the traffic dont get through until and unless I issue the ping myself locally on the Switch.

Once ping is issued the first packet of ping drops and then success.After which the traffic starts flowing.

I would like to know are there any known issue similar to that?

How can I solve it? Any comments will be valuable.

I am using Nexus 300o with System version: 5.0(3)U5(1c)

Below are some of the configurations from both switches.
