Today I am going to talk about the Aruba
Access point Instant overview and how to configure the NTP server on the Aruba
Instant. First of all we need to understand about the Aruba Instant.
What is Aruba
Instant ?
Aruba Instant virtualizes Aruba Mobility
Controller abilities on 802.11n access points (APs), generating a feature-rich
enterprise-grade wireless LAN (WLAN) that associates affordability and
configuration ease.
Aruba Instant is a easy way to deploy and
turn-key WLAN solution comprising of one or more access points. An Ethernet
port with routable connectivity to the internet or a self-enclosed network, is
used to position an Instant Wireless Network.
An Instant Access Point (IAP) can
be connected at a single site or positioned through multiple geographically detached
localities. Planned precisely for easy positioning, and proactive management of
networks, Instant is perfect for small customers or remote locations without
any on-site IT administrator.

Aruba Instant comprises of an Instant
Access Point (IAP) and a Virtual Controller (VC). The Virtual Controller dwells
within one of the access points. In an Aruba Instant positioning only the first
IAP requirements to be designed. After the first IAP is deployed, the succeeding
IAPs get all the essential data from the Virtual Controller.
The NTP server is set to pool.ntp.org by default. To configure the NTP server on
Aruba Instant, perform the following steps.
- Navigate to the Settings tab in the top right corner of the Instant UI.
- In the General tab, enter the IP address or the URL (domain name) of the NTP server in the NTP
- Server text box and click OK.
- Select the time zone from the Time zone drop-down list. This indicates the time returned by the NTP server.

Aruba Instant does not need an exterior
controller to control and achieve the Wi-Fi network. Any IAP in the Aruba
Instant network vigorously takes up the role of a Virtual Controller (VC)
without disturbing the existing network. It directs, stores, and allots all the
sets needed to deliver a centralized functionality to control and manage the
Wi-Fi network.
The Virtual Controller also functions like any other AP with
full RF scalability. It also deeds as a node, managing DHCP address allotment
for network address translated clients guaranteeing mobility of the clients
when they wander between diverse IAPs.
