On Huawei VRP, Advanced IPv4 ACLs (which can match source IP, destination IP, and L4 port numbers) use the 3000–3999 numbering range.

2000–2999 = Basic IPv4 ACL (matches source IP only).

3000–3999 = Advanced IPv4 ACL (matches source/destination IP, protocol, ports).

4000–4999 = Layer 2 (MAC) ACL.

5000–5999 = User-defined/other ranges, not the standard advanced IPv4 range.

Therefore, to match IPs and ports, select 3000–3999.

Huawei GPON service provisioning supports mapping upstream/downstream service flows to GEM Ports using multiple classifiers, including MAC address, physical port (PORT), VLAN ID, and 802.1p (priority). These classifiers are configured in line/service templates (and pushed via U2000) to ensure precise flow-to-GEM binding.

In IP multicast, only one copy per multicast group (program) is forwarded upstream, regardless of how many users are watching it. Replication happens downstream at the access/edge, not toward the core. Therefore the upstream traffic equals the number of active multicast groups × per-group bitrate:

20 programs × 2 Mbit/s = 40 Mbit/s.

This behavior is consistent with Huawei’s multicast feature descriptions and general multicast principles (IGMP/PIM), which explain that multicast traffic is sent as a single flow per group and replicated only where branching occurs, not multiplied by user count.
