Ethernet VLAN identifiers provide a practical limit of about 4K per broadcast domain. As user counts and services grow toward this boundary, Huawei recommends dual-layer VLAN (QinQ) to extend scale and maintain service isolation. Hence the planning threshold is ~4K.

The ONT details pane in eSight displays access-port attributes (admin/state, type), Ethernet rate/speed/duplex, and PON optical module telemetry such as temperature and Tx/Rx optical power for condition monitoring and troubleshooting.

For IPv4 multicast, the MAC mapping uses 01-00-5E followed by the low-order 23 bits of the multicast IP address. Because an IPv4 multicast address has 28 variable bits (224/4), 5 bits are not mapped to the MAC. Therefore, 2⁵ = 32 distinct multicast IP addresses can map to the same multicast MAC address.
