What is AP array
Slave

Master
• AP array is a function aimed at simplifying configuration. • Allows Administrator to create a set of devices on a network that are
organized into a single group in order to increase ease of management. • If some configuration needs be changed in those APs in the same group, the
administrator just need to change the configure in Master unit, and the change will be applied to Backup Master and other slave units automatically, and no need to apply the change one-by-one in the same group.
Change Config in Master Unit

How AP array works
• Master check configuration Slave and Backup• Master sync configuration Slave and Backup• Master configure Slave and Backup• AP array works on Ethernet and it should in the same network• Max connected number: 8*APs in a group

Typical AP Array Application
• IT deployed wireless network on each floor but if the device did not support AP array: IT will take a lot of time to configure each AP one-by-one.
• Now, the device supports AP array: IT just configured Master and the others are configured automatically.

AP Array Configuration Terms
• Enable AP Array: check this box to enable the AP array function. The three modes that available are master, backup master, and slave. APs in the same array will use the same configuration.
• The configuration will sync the Master AP to the Slave AP and the Backup Master AP when a Slave AP and a Backup Master AP join the AP array
• AP Array Name: enter a name for the AP array you have created• AP Array Password: enter a password that will used to access the AP
array you have created.• Scan AP Array list: click the button to initiate a scan of all the available
APs on the network.• Connection Status: this displays the status of the current AP array.

Configure Example
Objective:1. Configure AP Array Group, in one Master unit, and Slave Units.2. Change some configure in Master unit (eg, SSID), and check if the change will be synced to Slave unit(s) AUTOMATICALLY.
Configure Example – At Master Unit
• Check “Enable AP Array”• Select “Master”• Configure your own AP array name and password, for example,
AP Array Name = d-link AP Array Password = d-link
Configure Example – At Slave or Backup Master
• Check “Enable AP Array”• Select “Slave”• Configure your own AP array name and password to the same one as
configured in Master Unit, for example, AP Array Name = d-link AP Array Password = d-link
• Change something in master, for example, SSID from original “dlink” to new “howToVerifyAParray”
• Check slave whether the config will be “synced” with master automatically• Check the result by Telnet or Web (to Master and Slave units)
Configure Example – Test Result
Master Before:WAP-> get arrayrAP array role is master(current role is master)WAP->WAP-> get ssidSSID:dlinkWAP->WAP-> get arraycfgAP array cfg verion: 1WAP->
Master Change Configure:WAP-> set ssid howToVerifyAParraySSID:howToVerifyAParrayWAP->WAP-> set apply#!/bin/shlimitedadmin.sh...#!/bin/shpingctl.sh...WAP->WAP-> get arraycfgAP array cfg verion: 2
Slave Before Change:WAP-> get arrayrAP array role is slave(current role is slave)WAP->WAP-> get ssidSSID:dlinkWAP->WAP-> get arraycfgAP array cfg verion: 1WAP->
Slave Synced by Master:WAP-> get ssid SSID:howToVerifyAParrayWAP-> get arraycfgAP array cfg verion: 2WAP->
The Master configure will sync to Slave units automatically.
AP Array Behaviors - I
• If fake Master joins into this group, what will happen?• This fake Master will not affect to this group.

• If one Slave leaved and then joined into this group, what will happen?• It will connect with Master each other. • Master will sync configuration version with the Slave

AP Array Behaviors - II
• If Master leaved and then Backup became the Master in this group, after a while, Master back to this group, what will happen?
• Backup Master will change its role from Mater to Backup Master.
