HP Unified Wireless: R3507P22 includes Apple Bonjour gateway

HP has released firmware R3507P22 for the Unified wireless controller portfolio (830/850/870 appliance controllers and 20G module).

Sample of the 870 controller:

Several new features have been included, 2 interesting new features are:

  • Support for vlan-pool at the AP-group configuration level
  • Includes an Apple Bonjour gateway proxy and filtering solution

VLAN-Pool feature

This is a sample configuration for an education topology with 2 campus locations, which takes advantage of the new vlan-pool feature on an AP group. (vlan-pool was already supported, but had to be set per AP).

The example assumes:

  • APs in CampusA have an IP Address in the  10.1.20.0/23 range
  • APs in CampusB have an IP Address in the 10.1.30.0/23 range
  • An open SSID is configured in this example (just to keep the example simple)
  • All traffic will be centrally forwarded by the controller
  • APs from CampusA will be auto-assigned to the AP-group CampusA when they come online for the first time.
  • APs from CampusB will be auto-assigned to the AP-group CampusB when they come online for the first time.
  • Students in CampusA will be distributed to a vlan pool StudentsA (VLAN21-29)
  • Students in CampusB will be distributed to a vlan pool StudentsB (VLAN31-39)
  • The Service template is bound to a virtual Layer2 interface with PVID VLAN 20. This PVID will be used to assign to wireless users in case an AP from another site gets the service template (without a vlan or vlan pool binding)
  • Assuming each VLAN is configured with a /24, it can handle about 240-250 users. About 2000 wireless users (240*9) per campus can be handled based on this config, all distributed in /24 ip subnets.

Apple Bonjour Gateway

The new release also includes support for an Apple Bonjour Gateway.

The Apple Bonjour protocol supports only local VLAN/IP Subnet discovery of services, which is annoying in case an Apple TV and Apple iPads are connected through different VLANs on the wireless network (like previous VLAN pool example)

The Bonjour gateway allows the AC to forward Bonjour requests to remote VLANs, and cache the resulting responses.

It can also apply service filtering through Bonjour policies, so the network administrator can control which users can use which services on which location.

For example, the Teachers on a wireless network may be allowed to access the Apple TV services, while the students can only access the printer services.

    Hm, I´m asking myself whether I can put that HP controller behind my existing non HP wifi controller and use it for Apple Bonjour only…?
