1.4.5 SNMP Trap on Config Change

For improved system administration,WS5000 v2.1 supports the following:
1. Send out a SNMP Trap whenever configuration in the switch changes. The change could be initiated by
CLI, GUI or SNMP.
2. The trap contains the time when the config was changed. The trap will not contain any details of the
config change itself.
3. The Switch stores the time when the config was last modified. This will not be persistent across switch
reboots.
4. Switch will maintain a count of total configuration changes. This will not be persistent across switch
reboots.

1.4.6 AP to AP Beacons

The purpose of this functionality is to measure and report the signal strength of beacons heard by each Portal
(radio) connected to the switch, periodically. Normally, any given Portal would hear beacons from at most all
the other Portals on its assigned channel. It may also hear beacons from 'nearby' Portals on adjacent channels.
This information will be reported by the switch as a new doubly-indexed table. The primary index is the
PortalIndex of the Portal that heard the beacons. The second index is the PortalIndex of the Portal from which
the beacons were heard. For each such combination, 7 pieces of data are tracked in a cumulative fashion,
(since switch reboot).

1.4.7 DTIM per BSS

This would allow for the setting of the DTIM on a per BSS basis. Each Access Port can run one WLAN for data
devices with DTIM 10 and another WLAN with DTIM 2 for VoIP phones. With this feature, not all the WLANS
need to have a lower DTIM value because that would drastically impact the battery performance of data
devices
This would involve sending new information elements, while doing a configuration of the Access Port.
The AP policy context will be enhanced to enable the user to set 4 separate DTIM interval values for 4 different
BSSIDs. DTIM value 1 will be used for BSS1, DTIM value 2 for BSS2, and so on. The first DTIM interval value
will also be the default, to be used when the AP does not support setting of DTIM per BSS. This will help the
user to know what DTIM values are actually used, depending on the BSS-ESS mapping, and will be indicated
as such through the user interfaces.

1.4.8 WIPS Support

The Wireless Intrusion Prevention System (WIPS), introduced in 2005 as an overlay system (to the wireless
infrastructure) to provide intrusion detection and prevention services. The system comprises of a WIPS server
(typically located at the NOC / Data Center) and the AP300 Access Ports that act as "sensors" and forward all
lists all the traps and syslog messages.
