Preference to an IAP with Non-Default IP
The Master Election Protocol prefers an IAP with non-default IP, when electing a Virtual Controller for the Instant
network during initial startup. If there are more than one IAP with non-default IPs in the network, all IAPs with default
IP will automatically reboot and the DHCP process is used to assign new IP addresses.
Viewing Master Election Details
To verify the status of an IAP and master election details, use the following commands:
(Instant AP)# show election statistics
(Instant AP)# show summary support
Manual Provisioning of Master IAP
In most cases, the master election process automatically determines the best IAP that can perform the role of Virtual
Controller, which will apply its image and configuration to all other IAPs in the same AP management VLAN. When
the Virtual Controller goes down, a new Virtual Controller is elected.
Provisioning an IAP as a Master IAP
You can provision an IAP as a master IAP by using the Instant UI or CLI.
In the Instant UI
1. In the Access Points tab, click the IAP to modify. The edit link is displayed.
2. Click the edit link. The edit window for modifying IAP details is displayed.
3. Select Enabled from Preferred master drop-down. This option is disabled by default.
