Describe the purpose of the service port on a Cisco WLC.
The service port allows for Out-Of-Band management via SSH or HTTPS.
Also referred to as a data management interface.
What port on a Cisco WLC is used to enable HA operations?
The redudancy port.
The data Ethernet port on a Cisco WLC is referred to as?
The distribution system ports.
What type of EtherChannel configuration is supported for the WLC’s distribution (Ethernet) ports?
A static LAG (Link Aggregation Group).
What type of interface is used to map a WLAN to a VLAN on the wireless controller?
The dynamic interface.
What layer do dynamic interfaces operate at on an IOS-XE wireless controller?
Layer 2
What layer do dynamic interfaces operate at on an AireOS wireless controller?
Layer 3
What configuration(s) are required on a dynamic interface on an AireOS controller?
IP Address, Subnet Mask, Default Gateway and a DHCP Server
Describe the purpose of the Wireless Management Interface (WMI) on a Cisco WLC.
Both IOS-XE and AireOS use WMIs for the same purpose:
- Terminating CAPWAP tunnels
- RADIUS authentications
- WLC to WLC communications
- SSH, NTP, and SNMP
What interface on a WLC uses a unique non-routable address and is used for specific client facing operations?
For example, relaying DHCP requests to a DHCP server.
The virtual interface
What is the maximum amount of WLANs that can be configured on a Cisco WLC?
512
What is the maximum amount of WLANs that can be active at one time on a Cisco WLC?
16
Each WLAN is advertised via their own unique ____.
Beacon.
How many active WLANs are recommened in a single area?
5 or fewer, but 3 maximum is best.
What are the 3 categories (tags) of AP operation on an IOS-XE controller?
Policy, Site, and RF.

Describe the purpose of the Policy category on an IOS-XE controller.
Policies define the WLANs and their security policies
Describe the purpose of the Site category on an IOS-XE controller.
Settings for the AP controller and CAPWAP/FlexConnect behavior on a per-site basis.
Describe the purpose of the RF category on an IOS-XE controller.
Settings for wireless bands and transmission.
