Hi, WDNJSQ.
The ACL configured on the VLANIF interface of the Cisco switch filters packets forwarded at Layer 3 (forwarding based on the Layer 3 routing table) but does not filter packets forwarded at Layer 2 (forwarding based on the MAC address table). Huawei switches do not support ACL-based packet filtering on VLANIF interfaces, but support packet filtering on VLANs. Packets forwarded at both Layer 2 and Layer 3 are filtered out on Huawei switches. Therefore, packets that are not permitted are filtered out. The configuration does not permit the packets between users on the same network segment. As a result, users in VLAN 100 cannot communicate with each other.
You can add an ACL rule to allow the communication between the network segments of the VLAN. For example: rule 15 permit ip source 192.168.1.0 0.0.0.255 destination 192.168.1.0 0.0.0.255.
Hope to help you!
