Enable IGMP-snooping at Layer 2. When the switch port receives an IGMP join message, it snoops the message and adds the corresponding port to the multicast group.

OLT can perform traffic shaping through service virtual ports (service-ports).

GPON system DBA scheduling is only for upstream traffic and cannot schedule downstream traffic.

In eSight's zero-configuration deployment of ONTs, when incrementally configuring an OLT, do not preconfigure the OLT.

When configuring multicast services, the VLAN that supports the group service must be consistent with the ID of the unicast VLAN.

The Traffic-suppress function of the MA5680T uplink port only suppresses unknown multicasts.

EA5800/MA5800 only supports IGMP-PROXY, not IGMP-Snoopin.

Generally speaking, the lower the suppression level of the OLT broadcast message, the more obvious the protection effect of the port/board on the broadcast traffic.

OLT has powerful rogue ONU control capabilities and can detect and isolate rogue ONUs in any scenario.

Link aggregation LACP only supports load sharing aggregation mode.

The traffic suppression function can work for unicast and multicast messages, but since broadcast messages are generally sent in the early stages of device communication, in order...

10G GPON, FEC is enabled by default and does not occupy downstream bandwidth.

During the evolution of EPON to 10G EPON, WDM modules are added at the central office to achieve a smooth transition and coexist with ODN.

EA5800/MA5800 only supports IGP-proxy, not IGMP-snooping

SIART type VLAN, by default, service virtual ports of the same VLAN cannot directly communicate with each other at Layer 2.

SNMPv2c version can encrypt user passwords.

GPON and 10G GPON use the same ODN network, but GPON and 10G GPON are two independent and non-interference channels that exist and work at the same time; each has its own exclusive...

Deploying Ethernet port protection groups in the upstream direction of the OLT can improve uplink reliability and uplink bandwidth.

The member ports in the LACP aggregation group send LACP packets to inform the other end of their system priority, system IP, port priority, port number, operation Key and other in...

Unlike the U2000, the eSight network management system cannot view the ONU ranging results, but it is suitable for viewing basic ONU information, such as luminous power.

The SIP protocol is an asymmetric protocol, and all actions of the SIP phone require the SIP server to issue control instructions.

When the OLT device forwards data, only user data that is not on the firewall blacklist can be forwarded normally. If the source IP address in the user message is on the firewall b...

The FTTH ODN network topology is generally a star-shaped networking structure.

In Type B protection mode, the Standby side port only receives light but does not emit light. When no upstream light is detected for four consecutive DBA allocation cycles, an upst...

After setting alarm customization for a certain alarm in the NCE system, the alarm reported from different devices will be modified before being put into the library.

Both XGS-PON and GPON have asymmetric upstream and downstream rates.

After the SIP voice service is activated in GPON, the status of the user port is queried and is Normal1, indicating that the status is normal.

When activating the SIP voice service, the configuration on the ONU and ONT sides is the same.

PON equipment can implement multiple 00s strategies such as A, flow classification, marking, traffic regulation, and congestion management in the FITX network.

NCE can configure alarm reporting filters for access devices, allowing access devices to selectively report alarm information.

In the NGN network, the H.248 protocol uses IP addresses for registration and authentication, while the SIP protocol uses terminal IDs to identify users.

There are three basic functional modules for optical cable splicing: splicing modules, patching modules, and integrated splicing and patching modules. The splicing, dispatching, an...

In the GPON system, OLT can use 512-bit AES encryption algorithm to protect data security.
