Configuring Virtual Controller IP Address
You can specify a single static IP address that can be used to manage a multi-AP Instant network. This IP address
is automatically provisioned on a shadow interface on the IAP that takes the role of a Virtual Controller. When an IAP
becomes a Virtual Controller, it sends three Address Resolution Protocol (ARP) messages with the static IP
address and its MAC address to update the network ARP cache.
You can configure the Virtual Controller name and IP address using the Instant UI or CLI.
In the Instant UI
1. Navigate to System>General.
2. Enter the IP address in Virtual Controller IP.
3. Click OK.
In the CLI
To configure the Virtual Controller Name and IP address:
(Instant AP)(config)# virtual-controller-ip <IP-address>
(Instant AP)(config)# end
(Instant AP)# commit apply
Configuring Timezone
You can configure time zone in which the IAP must operate by using the Instant or the CLI.
In the Instant UI
To configure time zone:
1. Navigate to System>General.
2. Select a time zone from the Timezone drop-down list.
You can enable daylight saving time (DST) on IAPs if the time zone you selected supports the daylight
saving time. If the Time Zone selected does not support DST, the Daylight Saving Time option is not
displayed. When enabled, the Daylight saving time ensures that the IAPs reflect the seasonal time
changes in the region they serve.
3. To enable daylight saving time, select the Daylight Saving Time checkbox.
4. Click OK.
In the CLI
To configure time zone:
(Instant AP)(config)# clock timezone <name> <hour-offset> <minute-offset>
(Instant AP)(config)# clock summer-time <timezone> recurring <start-week> <start-day> <start-
month> <start-hour> <end-week> <end-day> <end-month> <end-hour>
(Instant AP)(config)# end
(Instant AP)# commit apply
Configuring an NTP Server
To facilitate communication between various elements in a network, time synchronization between the elements and
across the network is critical. Time synchronization allows you to:
l Trace and track security gaps, network usage, and troubleshoot network issues.
l Validate certificates
l Map an event on one network element to a corresponding event on another.
