The total AP-Count license of a Cisco Catalyst 3850 Switch stack is equal to the sum of all the individual member
AP-Count licenses, up to a maximum of 50 AP-Counts. The total AP-Count license of the stack is affected when
stack members are added or removed:
●
When new members are added to the stack, the total AP-Count license of the stack is automatically
recalculated.
●
When members are removed from the stack, the AP-Count license contributed by the removed switch is
decremented from the total available AP-Count license in the stack.
●
If more AP-Counts are connected than the available AP-Count license, a syslog warning message indicates
this fact without disconnecting the excess connected AP-Counts until a stack reload.
●
After the stack reload, the surplus AP-Count s are removed from the total AP-Count. The following
examples explain the process.
Stack member addition example: A Cisco Catalyst 3850 Switch stack includes 3 switches, each with an AP-
Count license that allows 10 AP-Counts, for a total of 30 supported AP-Counts. When a new Cisco Catalyst 3850
Switch (switch 4) is added to the stack with an AP-Count license allowing 25 AP-Counts, the stack supports a total
of 50 AP-Counts because the total number of 55 access points (30+25) exceeds the stack limit.
Stack member removal example: In the preceding example, if switch 4 is removed from the stack, the AP-Count
license remains at 50 AP-Counts until the stack is reloaded, if 50 AP-Counts are connected and active in the stack.
After reload, the stack returns to its original value of 30 AP-Counts.
When the AP-Count for a stack exceeds 50, a syslog message appears in the active and member switches to
indicate the excess AP-Count:
