A. B. C. D. E. F.BCD.
The Cisco WiSM (Wireless Services Module) controllers have multiple interface types, each of which serves a specific purpose. Below are the explanations for the three true statements about the interface types of the controllers:
A. The service-port interface is the default interface for in-band management of the controller. The service-port interface is used for out-of-band management of the controller. It is the default interface for in-band management of the controller. When the service-port interface is configured, it takes precedence over the other interfaces for management traffic.
B. If the service port is in use, then the management interface must be on a different subnet than the service port. If the service-port interface is already in use, then the management interface must be on a different subnet than the service port. This is because the service port and management interface share the same MAC address.
C. You cannot ping the AP-manager interface. The AP-manager interface is used to communicate with the access points (APs) and is typically on a different subnet than the management interface. However, you cannot ping the AP-manager interface as it is designed to receive traffic only from the APs.
D. The virtual gateway interface is used to support mobility management. The virtual gateway interface is used to support mobility management. It is responsible for providing a virtual IP address to the APs, which allows them to roam between different controllers without interrupting the client's connection.
E. The management interface is used as the source IP address for all Layer 3 communications between the controller and the lightweight APs. The management interface is used as the source IP address for all Layer 3 communications between the controller and the lightweight APs. This is true even when the APs are connected to the AP-manager interface.
F. On the Cisco WiSM, the management interface is used to synchronize the supervisor engine and the Cisco WiSM. The management interface is used to synchronize the supervisor engine and the Cisco WiSM on the Cisco WiSM controller. The synchronization process ensures that the configuration is consistent across all the WiSMs in the system.
