[Knowledge Sharing] Configuration Synchronization

Hello all,

I wanted to talk today about configuration synchronization, a feature that was added in V2R7C20 of AC6005 and AC6605. Wireless configuration synchronization allows configuring WLAN services on only one of the two ACs, ensures that these configurations are automatically synchronized to the other AC, and so greatly reduces the configuration workload. In addition, this function facilitates configuration maintenance because all configurations are synchronized between the two ACs.
In order to have configuration sync between two ACs you will first need to establish HSB between them.
HSB stands for Hot-standby backup and is used for data synchronization and traffic switching. Data synchronization is performed to ensure consistent information on the master and backup devices when the two devices are working normally. Traffic switching is performed to ensure non-stop service forwarding when the master device fails or recovers.
After HSB is configured you can configure the configuration synchronization between the two ACs, but before that you will first need to know that not all configuration lines will be copied from AC1 to AC2, there are two types of configuration lines, public configuration and private, the synchronization will be done only on the public configuration part.
Common public configurations include:
§  Configurations of roaming and wireless services including radio,SSID, WLAN security, radio resource management, and positioning.
§  Configurations of NAC and AAA, including MAC authentication,802.1x authentication, external Portal authentication, AAA authentication,RADIUS authentication, and TACACS authentication, excluding access userconfiguration and built-in Portal configuration used for local authentication.
§  Configurations required by wireless services, including VLANpool, time-range, ACL, free-rule, QoS, and passthrough-domain.
§  URL filtering, signature database upgrade, intrusion prevention,antivirus, and Smart Application Control (SAC) configurations.

Common private configurations include:
§  VLAN, interface, IP address, routing, DHCP, DNS, and IPSecconfigurations.
§  Wired configurations including basic configuration, device management, interface management, network interconnection, and network management configurations.
§  Wireless configuration synchronization, CAPWAP, backup, and online parameter configurations.
§  Access user configuration and built-in Portal authentication used for local authentication.
§  AP upgrade configurations, including the upgrade file, mode, and task, FTP server, SFTP server, and maximum number of APs that can be concurrently upgraded.
