Controller Based WLANs

How can we do AP specific configuration from the commandline in ArubaOS?

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
Aruba AP BSS Table
------------------
bss                ess    port  ip            phy    type  ch/EIRP/max-EIRP  cur-cl  ap name            in-t(s)  tot-t       mtu   acl-state  acl  fm
---                ---    ----  --            ---    ----  ----------------  ------  -------            -------  -----       ---   ---------  ---  --

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

9c:1c:12:a8:3a:11  SSID-B  N/A   10.150.2.251  a-HT  ap    44+/21.5/22       0       AP-B     0        3m:47s  1570  -          2    T

 

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

----  --------------

Total:0

(local-5) (config) #show ap bss-table
