They can all use for home and SOHO users, indoor optical network terminal (ONT)
 
The difference:
1 Ports:
HG8240 Ports: 2POTS + 4GE
HG8245 Ports: 2POTS + 4GE + 1USB + 1Wi-Fi
HG8247 Ports: 2POTS + 4GE + 1USB + 1CATV + 1Wi-Fi
 
2 As the ports shown in above, the HG8240 no WI-FI and IPTV function, just works as a light cat.
 
3 HG8245 and HG8247 with the wireless WIFI and IPTV function, can connect to the spare battery unit and USB storage devices.
 
4 HG8247 has the CATV coaxial cable port, can directly connect to TV, while the HG8245 can only use the cable connection to achieve this function.

Configuring and Activating an MST Region - Basic MSTP Functions

How to configure basic MSTP functions on Huawei router, configuring and activating an MST region, at the network time, I use the router AR3200AR1200 most.
 
Context
An MST region contains multiple switching devices and network segments. These switching devices are directly connected and have the same region name, same VLAN-to-instance mapping, and the same configuration revision number after MSTP is enabled. One switching network can have multiple MST regions. You can use MSTP commands to group multiple switching devices into one MST region.
 
NOTE
Two switching devices belong to the same MST region when they have the same:
l Name of the MST region
l Mapping between VLANs and MSTIs
l Revision level of the MST region
Perform the following steps on a switching device that needs to join an MST region.
 
Procedure

Users Cannot Communicate After VLAN Mapping Is Configured ?

I Cannot Communicate After VLAN Mapping Is Configured ? I use the switch S5700-28C-SI most time on the network.

This section describes the troubleshooting flowchart and provides a step-by-step troubleshooting procedure to use when users cannot communicate after VLAN mapping is configured.
 
Common Causes
Users in VLAN 6 need to communicate with users in VLAN 5 over
an ISP network. The carrier assigns VLAN 10 as the stack VLAN (S-VLAN). Single-tag VLAN mapping is configured on GE0/0/1 of SwitchC and SwitchD to map customer VLANs (CVLANs) 5 and 6 to S-VLAN 10.

 
After VLAN mapping is configured on the interfaces, users in different VLANs cannot
communicate with each other. This fault is commonly caused by one of the following:
1 The translated VLAN (specified by map-vlan) has not been created.

How to Do If the Root Password of Huawei MA5600 Is Lost

Question:
How to do if the root password of a device is lost, for Huawei MA5600 series, such as MA5680T ?
 
Answer:
After using the device, the user may change the default user name and password. If all the users forget their password, resolve the problem by using the following method 1. If any other user can log in to the device, resolve the problem by using the following method 2.
 
Method 1: Load the empty database matched the device again. After restarting the device, log in to the system by using the default root password admin(OLT) or mduadmin(MDU).
This method will lead to loss of data configurations and the user needs to configure the data again.
 
Method 2: If the device is managed by the NMS (Network Management Server), modify
the configuration file on the NMS as follows:
