duplicate mac addres when I create svi 16 and 22 on C-9300

[sebastianc08]

Hello community!!

I have a problem with 2 Cisco Catalyst 9300 in stack.

When I create the interface vlan 16 and the interface vlan 22, both interface have the same mac address.

I workaround the situation, setting the mac addres under the interface command, but I would like to know if this behavior is a bug or not. Really I need fix it.

I make a test with another catalyst 9300 and the situation was the same. 

Anyone, can you help me with it?

Hi,

Having the same MAC address for multiple SVIs should not be an issue. For more info refer to this document:

have not see this problem any time before.

1. if this stack - check the stack ring having any issue.

2. check the SN again cisco inventory 

or may be bug, update to 17.64 and check
