WS5000 Series Switch System Reference Guide
WFQ uses one queue for each classification group, up to eight queues total, and one queue for all other data.
For example, if the network has only one classification group for VoIP and no others, then WFQ automatically
uses 2 queues: one for VoIP and the other for "all other data"—data not defined in a classification group. Each
additional classification group uses another queue and keeps one queue open for "all other data".
The allocation setting determines the percentage of available network bandwidth for data from a classification
group. For example, if the WFQ allocation for VoIP data is set to 80%, then four packets of VoIP data are sent
for every one packet of other data during periods of network congestion.
WFQ is implemented for the different types of traffic on the same ESSID and Access Port (AP) as well as
between different ESSIDs on the same AP. This implementation shares voice and non-voice traffic across
different network paths, thereby balancing the traffic load. A large volume of non-voice traffic on one ESSID
doesn't starve voice traffic on another ESSID on the same AP. WFQ is enabled and disabled in a network output
policy.

1.3.9 Simple Network Management Protocol (SNMP) Overview

SNMP defines the method for obtaining information about network operating characteristics as well as router
and gateway behaviors. This application-layer protocol initiates the exchange of configuration and
management information between network devices. The SNMP architecture allows a variety of relationships
among network entities.
The Wireless Switch GUI and CLI permit enabling and disabling of certain SNMP features. Disabling these
features ("hardening" of the switch) helps manage security. Hardening of the KDC only is also permitted.
SNMP is also managed by the SNMP manager through a third-party SNMP client, software permitting the
manipulation and configuration of SNMP components. There are three elements in this process:
• Management Stations – Software managing SNMP protocol parameters and communicating with
SNMP Agents. The SNMP manager is responsible for this element.
• SNMP Agent – Local to the Wireless Switch, this SNMP server provides the network device
information. It processes information requests from the SNMP manager via the management station
using SNMP.
• Management Information Base (MIB) – The storage area for network-management information. It
consists of collections of managed objects, such as SNMP parameters and events. These objects
describe the state of a particular network device.

1.3.10 Accessing and Configuring the Switch Software

To access and configure the WS5000 Series Switch administration controls and options, the administrator can
access a CLI through a Telnet session, or log into a Web-based graphical user interface.
The command line interface (CLI) is accessible via Telnet, through the console port on the front of the wireless
switch, or through a Secure Shell (SSH) application (which enables protected access to the switch over the
CLI). All configuration and management functions can be performed through the CLI.
The Web-based graphical user interface (GUI) can be accessed securely from any Web browser on the
network. The GUI provides tools to configure and maintain the wireless system. It also provides real-time
graphs for displaying system load and traffic on the wireless network.
