Mobility controller discovery
The wireless mobility feature defines a mobility domain, which is an interconnection
between multiple controllers for the purpose of exchanging mobility information on wireless
users. For more information, see Chapter 9: Mobility traffic manager.
For the controllers to interconnect, each must have the Mobility controller discovery
option enabled. In addition, one controller must be defined as the primary mobility
controller. It acts as the central site for distribution of mobility information.
There can only be one primary controller for each mobility domain. On all other controllers
set IP address of primary controller to the IP address of the primary controller.
Note All controllers in the mobility domain must be running the same software version. This
means that the first two numbers in the software revision must be the same. For example:
All controllers running 5.4.x, or all controllers running 5.5.x.
Discovery automatically takes place on both the LAN port and Internet port. VLANs are
not supported.
Network requirements
The network that interconnects the controllers and APs that make up a mobility domain must
not block any of the following ports/protocols:
UDP port 1194
UDP port 12141
UDP port 3000
UDP port 3001
UDP port 3518
TCP port 5432
Internet protocol number 47 (GRE)
