AP with Flag ID

Jump to Best Answer
  • 1.  AP with Flag ID

    Posted Jul 03, 2014 08:33 AM

    Hello need some help.


    I have a Master and Local controller. Which initally had AP's split equally 50/50.

     

    However due to circumstances I needed to send all AP's that had been connected on the Local to the Master.

    So re-provisioned them to use the Master IP address.

     

    Since doing so all the AP's that had been on the Local controller still have the "Switch IP" as the Local IP address and they all have the flags ID. Although the flags seem to come and go depedning on how often I refresh the page......

     

    Basically those AP's that had been on the Local AP do not allow clients to connect.

     

    Regards,

    Red.

    That means inactive, dirty config. On the controller, can you run show profile errors

    Hi Thank you for the quick response.

    There was no messages  form "show profile-errors" see below-

    The D flag is usually temporary. If its persistent, you should call TAC. The I flag can be caused by a number of things, but most of them show up under profile-errors. Check to make sure you have the AP group created on the controller. The APs store the name of their AP group in flash and then try to join that same group. If it doesn?t exist, the AP will be ?I? flagged. It will also be I flagged if you don?t have any VAPs assigned to the AP group the AP joins. It might also be due to CPSec being disabled, but the VAPs assigned to the AP group are in bridge mode.

    Another big one? if you use VLAN pool names in the VAP, make sure that name exists on the controller where the AP is trying to terminate.

    How are your APs discovering the controller ?

    Do you have enough licenses on your master ?

    How do you have configured the AP system profile ? Are you using VRRP ?

    Try running the show log system all | include <ap Mac >
    Show ap debug status ap-name <ap name>
    this will give some idea why your are getting that flag

    show log system all | inc <ap MAC>

     Jul 3 08:50:48 :311004:  <WARN> |AP Burton-1stFlr-24:de:c6:c4:d4:da@10.41.11.4 sapd|  Missed 8 heartbeats; rebootstrapping

     

    Which suggests it keeps loosing sight on the Master controller?!!

    That's is correct , those APs are having issues reaching the master controller so they keep going back and forth between the master / local

    If the AP's are losing heartbeat to the controller.... Why does it only effect those AP's that had been configured with the Local as the primary LMS?

     

    All AP's now have the Master LMS profile and have been reprovisioned.

    Q: How are AP's discovering controller?

     A: Via IP address manually set when initially configured by console. E.g. Some AP's with Master IP, then some with Local IP.

       Since then I tried re-provisioning to set them all to the Master conrtollers IP address.

     

    Q: Do you have enough licenses?
     A: 145 License on each controller. 76 AP's deployed in totoal.

     

    Q: How is AP system profile configured? VRRP?
     A: VRRP is not used. We have a Primary and a Backup LMS specified

      e.g. Master AP with Primary IP as Master and backup as Local.
                Local AP had Primary IP as Local and Master as backup.

     

    The Master has a AP-profile and the Local a different one.

    So im at the point now where I want all APs to use the Mater AP proflile and the Master Switch. Which I set on re-provisioning.

     

    I've not had much time on this and being thrown in at the deep end....

     

    Thank you for your help.

    What do you mean a different profile on each controller ?


  • 13.  RE: AP with Flag ID

    Posted Jul 03, 2014 09:51 AM

    Each has a different AP system Profile.

     

    So When assigned to the Master or Local controller the appropriate AP has the correct controller as its primary/backup LMS.

    Do you have other APs that are the IP segment join to the master controller with no issues ?

    Under the AP provisioning settings what do you have configured ? Can you remove any manual settings and allow the APs to find the controller based on the ap system profile ?

    Hi Victor,

     

    Q: Do you have other APs that are the IP segment join to the master controller with no issues?

    •  A: Yes, I have a site which has 6 AP's. Two of which are newly deployed AP's and I set via console on my desk with the serverip and master as the "MASTER" IP address. The already installed AP's orignally had the Local IP set as both server and master IP as the Local address.
    • The newly deployed AP's work as expected. The AP's previously configured to use the local do not.
    • Regards, Red.

    Why do you assign the controller manually that way ?

    You should implement either dhcp option 43 or DNS Aruba-master for APs to discover your controller.

    To get to the bottom of this you should probably open a TAC they will be able to look at your environment and determine what's causing this issue

    Hi Victor,

     

    We only have two controllers and the IP's are static and not going to change so it was our preference to use static IP.

     

    Thankyou for your help.

    Hello All,

     

    Just wanted to update this post with a solution.

     

    To recap..... We have two controllers

       North-(Local (Backup))   &   South-(Master)

     

    We originally configured (via console) our AP's according to which controller was the closest e.g.

     

    Northern-AP                                              Southern-AP

      setenv ipaddr 10.3.1.1                          10.2.1.1
      setenv netmask 255.255.0.0               255.255.0.0
      setenv gatewayip 10.3.0.1                    10.2.0.1
      setenv serverip 192.168.1.10             192.168.0.10
      setenv master 192.168.1.10               192.168.0.10

     

    Everything was working until.....

    We then needed to change (re-provision) all Northern AP's to use the Southern controller.

    Doing this via the GUI lead to the Northern AP's constatnly flapping between both controllers and showing/flapping the flags D (Dirty) & I (inactive).

     

    The solution-

    Disbale ADP on the Northern-(Local) controller.

    Although configured manually we found that ADP was not helping our setup.

    This fixed the majority of re-provisioned AP's

     

    Next for those stuborn AP's  that still kept falpping. We re-re-provisioned with a new IP in the same range.

    E.g for an AP that had IP 10.3.1.1 we moved it to 10.3.1.10.

     

    All AP's are now using the Southern-(Master) controller.
