Mobility group

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

A mobility group is a configuration grouping that allows wireless LAN controllers to coordinate client roaming across access points they control.

A mobility group lets multiple wireless LAN controllers coordinate client roaming between access points managed by different controllers. section 21.1.2 section 21.4

Distinguish the mobility group from the related RF group:

  • Use the mobility group to support roaming clients across controllers. section 21.1.2
  • Use the RF group to coordinate radio-frequency settings such as power levels and channel selections. section 21.1.2
  • Set the mobility and RF groups separately later through the GUI, although they are usually assigned the same name. section 21.1.2

Initial WLC configuration

During the Cisco Wizard Configuration Tool, enter a shared name at the Mobility/RF Group Name prompt, such as ManningCCNA. This establishes the mobility-group setting while initial WLC parameters are configured. section 21.1.2

Mobility/RF Group Name: ManningCCNA

Inspect the wizard entry used to configure the Mobility/RF Group Name. section 21.1.2

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes
Defines the roaming role and distinguishes RF coordination, but does not provide verification commands or troubleshooting procedures.
Examples
Uses the Cisco configuration wizard prompt with the example group name ManningCCNA.
What it assumes
Assumes familiarity with wireless LAN controllers and access points while defining the mobility-group and RF-group distinction.
What you can do after
Operate/configure a WLC’s mobility-group setting during initial configuration and distinguish it from RF-group configuration.
How it connects
Connects wireless LAN controllers, access points, client roaming, and RF groups.
