  • Page 19: Image-Based License In A Stack

    Image-Based License in a Stack In a Cisco Catalyst 3850 Switch stack, all switches must be at the same image-based license (IP Services/IP Base/LAN Base) level. The active switch license level is considered the reference, and the member switch licenses are compared to it. If there is a mismatch, the active switch displays a syslog message saying that the stack configuration was unsuccessful.

  • Page 20: Ap-Count License In A Stack

    AP-Count license is available only with IP Base and IP Services licenses. A Cisco Catalyst 3850 Switch stack can support a maximum of 50 access points. An AP-Count license is required only if a Cisco Catalyst 3850 Switch is configured as both a mobility controller and a mobility agent. An AP-Count license is not needed if the Cisco Catalyst 3850 Switch is configured only as an mobility agent, which is the default configuration.
  • Page 21 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: ●...

  • Page 22: License Migration Between Switches

    By default the Cisco Catalyst 3850 Switch stack is configured as a mobility agent. In the wireless licensing model, a mobility agent is the access point count enforcement point.

  • Page 33: Converged Access With The Cisco Catalyst 3850 Switch

    Converged Access with the Cisco Catalyst 3850 Switch The Cisco Catalyst 3850 Switch can serve as an integrated wireless LAN controller for up to 50 directly attached Cisco access points and 2000 clients per stack. The Cisco Catalyst 3850 Switches can form the basis of a deployment that supports up to 250 Cisco access points and 16,000 clients.

  • Page 34: Logical Hierarchical Groupings Of Roles

    Because it performs these important functions, a mobility controller is a mandatory element in the converged access deployment. The mobility controller software function resides in the active member of a Cisco Catalyst 3850 Switch stack and can be assumed by the standby switch if the active switch fails. The active switch in a stack can host both the mobility controller function and the mobility agent function for all the locally connected Cisco access points.
