What is a mobility group?

What is a mobility group?

A mobility group is a set of controllers, identified by the same mobility group name, that defines the realm of seamless roaming for wireless clients. With this information, the network can support inter-controller wireless LAN roaming and controller redundancy.

What is Mobility Group and mobility domain?

So the Mobility Group name is defined in the Mobility Domain field. Any entities that are not in the same group name, but are listed in the Mobility List will have a different Mobility Group name defined. This means they are simply in a different Mobility Group. Roaming can occur within and between Mobility Groups.

What is WLC mobility?

Mobility Anchor, also referred to as Guest tunneling or Auto Anchor Mobility, is a feature where all the client traffic that belongs to a WLAN (Specially Guest WLAN) is tunneled to a predefined WLC or set of controllers that are configured as Anchor for that specific WLAN.

What is inter xTR?

In SDA, xTR stands for an access-switch that is a fabric edge node. When a client on a fabric enabled WLAN, roams from an access point to another access point on a different access-switch, it is called Inter-xTR.

How many mobility domains can a controller be a member of?

A controller can be part of multiple mobility domains, although Aruba recommends that a controller belong to only one domain. The controllers in a mobility domain do not need to be managed by the same master controller.

What is wireless anchor?

Cisco defines mobility anchoring as: Mobility Anchor, also referred to as Guest tunneling or Auto Anchor Mobility, is a feature where all the client traffic that belongs to a WLAN (Specially Guest WLAN) is tunneled to a predefined WLC or set of controllers that are configured as Anchor for that specific WLAN.

What is mobility domain?

A mobility domain is a cluster of APs forming a continuous radio frequency space, where the Pairwise Master Key (PMK) can be synchronized, and fast roaming can be enabled for 802.11r (Fast Transition) or 802.11i (WPA).

What is an anchor controller?

In auto-anchor mobility mode, a subset of a mobility group is specified as the anchor controllers for a WLAN. You can use this feature to restrict a WLAN to a single subnet regardless of a client’s entry point into the network. Usually this is used for service guests in a corporate network.

What is Cisco Ircm?

Inter-Release Controller Mobility (IRCM) supports seamless mobility and services across different wireless LAN controllers that runs on different software and controllers. This document specifically covers the IRCM support between catalyst 9800 wireless controllers and interoperability with AireOS controllers.

What is mobility MAC address?

MAC mobility describes the scenario where a host moves from one Ethernet segment to another segment in the EVPN network. Provider Edge (PE) devices discover the host MAC address from its local interfaces or from remote PE devices.

What is mobility domain ID?

A Mobility Domain ID is used by 802.11r to define a scope of the network in which an 11r fast roam is supported. Master keys are shared within the Mobility Domain, allowing clients to support a fast roam.

What is mobility anchoring in LTE?

It handles user handovers between neighboring eNBs. A PGW is a user plane component, which forwards packets between the LTE network and other packet networks. It is controlled through the S5/S8 interface by the SGW. Moreover, PGW is a mobility anchor for end users.
