Captive Portal Aruba Running very slowly ….


Hari ini ini saya mendapati kejadian susah sekali dalam mengakses halaman captive portal login dari SSID Wifi@UNILA Aruba,  susah akses login terutama ketika jam sibuk antara pukul 08.00 – 14.00,  asumsi awal saya sepertinya ada masalah redirect web login page di controller ketika user akan membuka url/web tertentu, browse sana sini, googling sana sini, akhirnya nemu url berikut http://community.arubanetworks.com/t5/Unified-Wired-Wireless-Access/Captive-portal-slow/td-p/33715 , ada yang menyarankan cek status web-server di controller. Dari saran ini langsung meluncur ke controller dan cek status dari web server, rupanya nilai default dari controller saya adalah 65, ini artinya concurrent client yg bisa dilayani rupanya hanya 65 … hadeh… :-(  , berdampak pada load CPU/Memory controller yg sangat rendah.

(CTRL-MASTER-UNILA-XXX01) #show web-server
Web Server Configuration
------------------------
Parameter                                      Value
---------                                      -----
Cipher Suite Strength                          high
SSL/TLS Protocol Config                        xxx xxx
Switch Certificate                             xxx
Captive Portal Certificate                     xxx
Management user's WebUI access method          xxx
User session timeout <30-3600> (seconds)       900
Maximum supported concurrent clients <25-320>  65
Enable WebUI access on HTTPS port (443)        false
Web Lync Listen Protocol/Port Config           N/A

(CTRL-MASTER-UNILA-XXX01) #show cpuload
user 10.0%, system 10.1%, idle 79.9%

Setelah ditunning, naikkan nilainya kebatas maksimal yaitu 320, maka sekarang load CPU/Memory  sudah naik, akses captive-portal disisi user juga sudah berjalan normal.

(CTRL-MASTER-UNILA-XXX01) #show cpuload UNILA-01) #
show cpuload user 26.7%, system 32.2%, idle 41.1%

Demikian sekilas info catatan Ngoprek siang ini. Mudah-mudahan ada gunanya.
