Requirement:
This article was tested on Aruba OS 6.4. on a master-standby-local setup.
Solution:
We need to configure AP specific from the master controller. If the AP is on one of local controllers, we need to push the configuration to local controller by giving a "write memory" command.
Configuration:
Below, we have three controller in Master-standby-local configuration:
(master) (config) #show switches
All Switches
------------
IP Address Name Location Type Model Version Status Configuration State Config Sync Time (sec) Config ID
---------- ---- -------- ---- ----- ------- ------ ------------------- ---------------------- ---------
10.17.171.6 master Building1.floor1 master Aruba7210 6.4.3.7_53990 up UPDATE SUCCESSFUL 0 3
10.17.171.3 standby Building1.floor1 standby Aruba3200 6.4.4.5_54063 up UPDATE SUCCESSFUL 11 3
10.17.171.4 local-5 Building1.floor1 local Aruba3600 6.4.3.7_53990 up UPDATE SUCCESSFUL 6 3
Total Switches:3
We have two APs, one on the master, other on the local controller:
(master) (config) #show ap database
AP Database
-----------
Name Group AP Type IP Address Status Flags Switch IP Standby IP
---- ----- ------- ---------- ------ ----- --------- ----------
00:0b:86:ee:65:14 default 205H 10.17.171.29 Up 3h:49m:31s 2 10.17.171.6 10.17.171.3
AP-B default 135 10.150.2.251 Up 5m:6s 2 10.17.171.4 0.0.0.0
Total APs:2
Both the APs are in default group which makes them broadcast SSID names SSID-A. Below we see the BSS table of AP on local controller:
(local-5)#show ap bss-table

Both of these these APS are in default group which has VAP "SSID-A-VAP" responsible for SSID-A
(master) (config) # show ap-group default
AP group "default"
------------------
Parameter Value
--------- -----
Virtual AP SSID-A-VAP
802.11a radio profile default
802.11g radio profile default
Ethernet interface 0 port configuration default
Ethernet interface 1 port configuration default
Now, if we want to add another SSID SSID-B on AP-B on local controller without creating a new group and reprovisioning the AP, we need to Execute the "ap-name" command on the master:
(master) (config) #ap-name AP-B
(master) (AP name "AP-B") #virtual-ap SSID-B-VAP
(master) (AP name "AP-B") #write memory
Now when we check on the local controller, we see:
(master) (AP name "AP-B") #
(local-5) (config) #show ap-name
AP name List
------------
Name Profile Status
---- --------------
AP-B
Total:1
(local-5) (config) #show ap-name AP-B
AP name "AP-B"
--------------
Parameter Value
--------- -----
Virtual AP SSID-B
<truncated output>
Verification
We can see that AP on local controller has started broadcasting the SSID SSID-B in the bss table.
(local-5) (config) #show ap bss-table

We can remove the config from the master:
(master) (config) # no ap-name AP-B
(master) (config) #write memory
On the local controller, we can see that the AP is no longer broadcasting SSID-B:
(local-5) (config) # show ap-name
