Configuring MAPs 219

For example, suppose the Mobility Domain has two WX switches, with the capacities and loads listed in Table 15.

Table 15 Example WX1200 MAP Capacities and Loads

	WX1200 A	WX1200 B
Maximum Configured	30	30
Maximum Active	12	12
Number Currently Configured	25	20
Number Currently Active	8	12

For WX1200 A:

„The Number of MAPs that can be configured on the switch, minus the number that are configured, is 30 - 25 = 5.

„The Number of MAPs that can be active on the switch, minus the number that are active, is 12 - 8 = 4.

„The lesser of the two values is 4. The switch can have up to 4 more MAPs.

For WX1200 B:

„The Number of MAPs that can be configured on the switch, minus the number that are configured, is 30 - 20 = 10.

„The Number of MAPs that can be active on the switch, minus the number that are active, is 12 - 12 = 0.

„The lesser of the two values is 0. The switch can have no more MAPs.

WX1200 A has the capacity to add 4 more MAPs, whereas WX1200 B cannot add any more MAPs. Therefore, the WX contacted by the MAP sends WX1200 A’s IP address to the MAP. The MAP then requests a software image file and configuration from WX1200 A. WX1200 A sends the software image and sends configuration parameters based on the Auto-AP profile.

Configured MAPs Have Precedence Over Unconfigured MAPs

When a WX determines the WX IP address to send to a booting MAP, the WX gives preference to MAPs that are already configured, over unconfigured MAPs that require an Auto-AP profile. The WX can direct a configured MAP to a WX that has active MAPs configured using the Auto-AP profile, even if the WX does not have capacity for more active MAPs. In this case, the WX randomly selects a MAP using the Auto-AP profile to disconnect, and accepts a connection from the configured MAP in its place.
