Duplicate MAC addresses across VLAN's in E810 cards

[Balaji_G]

Hi All,

          I am using E810 NIC cards in my client & server.  I have 5 virtual interfaces [ ens2f0np0.5 to ens2f0np0.9 ] with the same MAC address in the client & 5 virtual interfaces [eth8.5 to eth8.9] with the same MAC on the server. 

So, my test recreates all the virtual interfaces everytime & tries to ping those IPV6 IP's from the host.

When i have 5 virtual interfaces on the client, i am able to ping the corresponding target IP's but

the issue happens when i have more than 5 virtual interfaces on the client. i.e when i increase the virtual interfaces count in the client by 1 then , none of the virtual interfaces are pinging from the host.

So, the question here is:

a) Can duplicate MAC address across VLAN in E810 NIC is accepted ???

b) Are there any limits on the num of duplicate MAC address  per port ?
