Adding ONT Huawei EchoLife HG8010 to Huawei SmartAX MA5683T

Suppose you configured OLT as I wrote in this article Configuring the Huawei SmartAX MA5683T through the console.
Now connect via telnet or console to the Huawei SmartAX MA5683T.
After entering the login and password, we will go into configuration mode by typing the command:

Limiting access to management of Huawei SmartAX MA5600

For example, to allow to connect to the Huawei SmartAX MA5600 series via telnet only to the specified IP address ranges and we will connect to the device and go into the configuration mode:


And execute the following commands (for non-specified IP access is immediately prohibited):

sysman ip-access telnet
sysman ip-access telnet
sysman firewall telnet enable

Similarly for SSH:

sysman ip-access ssh
sysman firewall ssh enable

And SNMP for example for one IP:

sysman ip-access snmp
sysman firewall snmp enable

To deny access to the specified subnet, we specify ip-refuse instead of ip-access, for example:

sysman ip-refuse telnet
sysman firewall telnet enable

On the test, I performed the settings for Huawei SmartAX MA5683T, they are essentially the same for the entire MA5600 series.

Reason for messages “Failure: System is busy, please retry after a while” on Huawei OLT

Once when executing commands in the Huawei SmartAX console, the MA5683T began to notice often the message:

Failure: System is busy, please retry after a while

As it turned out, the reason in my case was Zabbix, which every hour received SNMP levels ONT and drew graphics. SNMP requests from him were packed with packets of 30-50, separately for each port. I solved the problem by increasing the timeout in the Zabbix server configuration and the verification period for more hours, because OLT was slowly issuing information, Zabbix was not available, considered it inaccessible, paused briefly and sent requests again.
Also, in the settings of the Zabbix node, you need to uncheck “Use bulk requests”.
