Feature Description
Branch Controllers W-7000 Series controllers support distributed enterprises through the
following features designed specifically for branch and remote offices:
l Zero-touch provisioning
l Authentication survivability, which allows controllers to provide
authentication and authorization survivability when remote
authentication servers are not accessible.
l Integration with existing Palo Alto Networks Firewalls.
l Policy-based routing on each uplink interface, which allows you
specify the next hop to which packets are routed. This feature
supports multiple nexthop lists, ensuring connectivity if a device is
unreachable.
l Uplink and VPNredundancy, and per-interface bandwidth contracts to
limit traffic for individual applications (or categories of applications)
either sent from or received by a selected interface.
l Packet compression between Dell devices.
l Virtual APs for WAN link failure.
l A WAN health-check feature to measure WAN availability and latency
on each uplink.
AMON Messages Size
Changes on the Controller
The AMON message size change feature caps the AMON packet size at a
default value of 1500 bytes to reduce the amount of fragmentation and
message loss that typically occurs in larger packet sizes. Message size is
capped at 1400 bytes to allow for the addition of AMON and PAPI/UDP/IP
headers. This feature allows Dell controllers and W-AirWave servers to
communicate data using the faster, more reliable, and scalable AMON
model instead of the SNMPmodel.
Anyspot Client Probe Request
Suppression
The anyspot client probe suppression feature decreases network traffic
by suppressing probe requests from clients attempting to locate and
connect to other known networks. By reducing the frequency at which
these messages are sent, this feature frees up network resources and
improves network performance.
AP Scanning Optimization The AP scanning optimization feature enables APs to effectively visit and
monitor channels. By increasing the frequency of channel visits, the APis
able to gather the required data on time and input this information to the
client match algorithm.
BPDUGuard The Bridge Protocol Data Unit (BPDU) Guard feature protects port from
receiving STP BPDUs. The BPDUfeature is configured at the
port/interface level and enabled on edge ports.
Bluetooth-based Discovery
and AirGroup
AirGroup supports only mDNS-based device discovery and does not
support Bluetooth-based device discovery mechanism.
BSS Transition Management
Support
The BSS transition management support feature allows Client Match to
seamlessly steer devices using 802.11v BSS transition management
standards for continuous wireless connectivity.
