Ha Configuration; Ha Configuration Overview - H3C S7500 Series Operation Manual

Operation Manual – VRRP-HA
H3C S7500 Series Ethernet Switches
The configuration file of the slave board is copied from the master board in real time,
which can ensure that the slave system continues to operate in the same configuration
as that of the original active system after the master/slave switchover. S7506R
supports automatic synchronization of the configuration file. The active system stores
its configuration file and backs up the configuration file to the slave system
simultaneously when the master's configuration file is modified, so as to ensure the
consistency of the configurations of the active system and slave system. And you can
also use command to manually synchronize the configuration file of the master and
slave board.
Besides, the system can monitor the power supply and the operating environment of
the system and give timely alarms to avoid the escalation of failures and ensure safe
operation of the system.

2.2 HA Configuration

2.2.1 HA Configuration Overview

Complete the following tasks to configure HA:
Setting the Slave Board Restart Manually
Performing the Master/slave Switchover Manually
Enabling Automatic Synchronization
Synchronizing the Configuration File of the System Manually
Note:
When the S7506R starts, if you log in to the slave board, it will take about 3 minutes
before you can see the system prompt. During the 3 minutes, the slave board does
not respond to any operation. This is system protective design for avoiding
switching shake.
You cannot execute any command on the slave board until the slave board switches
to the master.
The master board will back up the configuration to slave board step by step as soon
as the system is up, which is a quick process. In this process, the system will give a
prompt on both master board and slave board if you press the "enter" key on the
terminal, at the time, you cannot execute any command on the master board. After
the block backup, the master board keeps doing the real-time backup with the slave
board and you can execute all commands on the master board.
You must keep the consistency of the version of the master and slave board.
