When a port enables ingress checking and VLAN trunking, the ingress checking will not work. This is because the VLAN trunking has a higher priority. Blew is an example. The port 1 enables ingress check and VLAN trunking, and the switch does not have VLAN 100. However, the switch can still forward the packets from unknown VLANs.
