lguohan commented 3 years ago

unknown mac only failed for dscp 3, 4, 8.

bingwang-ms commented 3 years ago

The issue was also observed on SN4600 T0 testbed. But the error is a little bit different. For dscp 3 and dscp 4, the packets were dropped, but drop counter didn't increase as expected. For dscp 8, the packet was forwarded according to FDB table before clear, and drop counter didn't show packet drop either.
