  • 1.  AP135 Up and Down problem

    Posted Oct 14, 2013 05:39 AM

    Hello,

     

    I am currently facing these Aruba AP model 135 problem. There are 310 units of them serving by 2 units of 3600 Controllers on Master/Local mode. The 135APs are provisioning into Remote APs with certificate. 

    1st unit of controller has 56 license, 2nd unit of controller has 256 license. So i should provision the 310 units of them to 56 units pointing to master, and 254 units pointing to local correct?

     

    Another problem i am facing is, some of the APs are down and up randomly, they were up for a few hours or few days then they went down and the other unit came up.

     

    I took a look at the controller's process log it shows something like this:

    Oct 15 13:31:00 sapd[836]: <404074> <WARN> |AP APR-246@10.100.100.98 sapd| AM 6c:f3:7f:56:a3:a0: ARM - increasing power cov-index 8/0 tx-power 3 new_rra 6/4

    The master controller sometime shows this:

    Oct 14 21:49:21 sapd[836]: <404069> <WARN> |AP APR-9407@10.100.100.98 sapd| AM 6c:f3:7f:56:bd:00: ARM Channel Interference Trigger new 11-120 old 6-163 new_rra 11/6 TCI 10

     

    May i know what is the issue that causing these?

    The switches that are connected by APs are PoE+ supported.

     

    Thanks for help

    Hi :smileyhappy:

    YES. (u may also consider using AOS 6.3.X with centralized licensing.All depends on your configuration,needs,and network topology)

     

    Another problem i am facing is, some of the APs are down and up randomly, they were up for a few hours or few days then they went down and the other unit came up.

     

    The logs u sent..arent relevant...your only copied ARM logs....

    if your ap units goes up and down..you should connect console for one of those units and u will be able to see the reboot reason.... Or u can search via cli " show log all | include reboot "
