One management sever IP can be mapped to only one kind of mgmt-server profile. The management server could be the Mobility Master itself or in addition to Mobility Master, an user may add an AirWave server as well.
Just configuring the Mobility Master as the management server primary-server and using profile will suffice to start sending stats and other information from the managed device to the Mobility Master, such as the managed device details, client info, APs and so on.
Its recommended to use managed devices to the Mobility Master. The reason being, if you decide to point your managed device to AirWave (AMP AirWave Management Platform. AMP is a network management system for configuring, monitoring, and upgrading wired and wireless devices on your network.) as well, then you would add another line of configuration for managed devices to point to the AMP AirWave Management Platform. AMP is a network management system for configuring, monitoring, and upgrading wired and wireless devices on your network.'s IP and use profile as the management-server profile. This helps in quickly identifying that the line using in it, is pointing managed devices to the Mobility Master and the other is pointing managed devices to AMP AirWave Management Platform.

Master-controller, Master-local, and Standalone are getting ARM Adaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. . Mobility Master will get AirMatch.
RFProtect is still controller-wide, so all APs on a controller still need all licenses relevant to their configuration.
Yes.
APs will not come up.
For deployments larger than 10k, multiple Mobility Masters are required. We hope to increase that scalability in the near future, but for now this is our ceiling.
Mobility Master can be configured to manage multi-tenant deployments, but is not configured to allow multi-tenancy admin logins. Right now, admin sees everything in the Mobility Master.
Licenses should be migrated from the LMS Local Management Switch. In multi-controller networks, each controller acts as an LMS and terminates user traffic from the APs, processes, and forwards the traffic to the wired network. to transfer the controller licenses to the Mobility Master. Additionally, new licenses can be purchased and activated on the Mobility Master, but the Mobility Master will not automatically inherit the controller licenses.
No, the Mobility Master is not terminating any APs and is not part of the datapath. IAP-VPN Virtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network.

In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. probing is done in the following scenarios:
When the peers in the cluster are moved to L3 connected state, VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. probing is triggered.
Probe is done when exclude VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. list is modified.

A special ether-type of 0x88b5 is used for vlan Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. probe packets.
When there is only node in the cluster, that node is the cluster leader. As more nodes are added, the cluster leader is elected based on the highest effective priority derived from configured priority, platform value, and the MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the device.
