How do you associate AP with WLC?
Manually Configure Lightweight AP to join WLC
- Configure a temporary WLC with the same name and IP Address of the WLC I want my APs to join.
- Utilise DHCP Option 43 to ensure a cross-subnet discovery is available.
- Manually set the Controller IP address via the CLI.
What is lag mode in WLC?
LAG is a partial implementation of the 802.3ad port aggregation standard. It bundles all the ports of the controller into a single 802.3ad port channel. The controller manages redundancy and load balancing of all the APs across the ports.
What is the recommended maximum RTT between an AP and the WLC?
D. The RTT between the AP and WLC should not exceed 300 ms.
How do I enable LAG in WLC?
Config required on WLC:
- Login to the WLC.
- Click Controller.
- Click General.
- Set “LAG Mode on next reboot” to “enabled”.
- Save Configuration and Reboot.
How do we prevent loops on the WLC?
You can enable STP on the WLC to prevent loops. From the WLC GUI click Controller, then navigate to the Advanced submenu located on the left side of the application. Click the Spanning Tree option, and choose Enable for Spanning Tree Algorithm located on the right side of the application.
What is required to use the service port on a WLC?
The service port is used for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. It is important to note that the service port does not support VLAN trunking or VLAN tagging and is therefore required to connect to an access port on the switch.
What is FlexConnect in WLC?
FlexConnect is a wireless solution for branch office and remote office deployments. From a central Wireless LAN Controller (WLC), hopefully in your Data Centre with a redundant WLC not too far away, you can configure, control and manage access points in a branch or remote office.
How does a AP discover WLC?
The WLC validates the AP and then sends an LWAPP join response to the AP. The AP validates the WLC to complete the discovery and join process. The validation on both the AP and WLC is a mutual authentication mechanism. An encryption key derivation process is subsequently initiated.
Why would an AP that successfully discovers a WLAN controller be denied from joining that WLC?
Explanation: A WLC will deny an AP from joining it if the maximum number of lightweight APs already joined to it has already been reached.
What protocol does the WLC use to learn about the AP?
Control and Provisioning of Wireless Access Points (CAPWAP) is a standard and interoperable protocol that enables a Wireless LAN Controller (WLC) to manage access points (AP) or wireless termination points (WTP). CAPWAP is based on the Lightweight Access Point Protocol (LWAPP).
Does link aggregation increase latency?
This method allows for simple implementation in switches and servers. Because it does not require additional buffers, no latency increases are attributable to link aggregation.
What are two types of LAGs?
Two types of LAGs are supported:
- Static—The ports in the LAG are manually configured.
- Dynamic—A LAG is dynamic if LACP is enabled on it.
- By MAC Addresses—Based on the destination and source MAC addresses of all packets.
What is one reason to implement LAG on Cisco WLC?
LAG removes the requirement for supporting multiple AP-manager interfaces. When you enable LAG, all dynamic AP-manager interfaces and untagged interfaces are deleted, and all WLANs get mapped to the management interface.
How can switching loops be prevented?
Switching loops can be prevented using Spanning Tree Protocol (STP). The purpose of Spanning Tree Protocol is to select the fastest network path if there are redundant links in the network.
