Wi-Fi device discovery support in Tivoli Network Manager 4.2

Body

In Tivoli Network Manager 4.2 GA, discovery support for Wi-Fi devices is made possible using the Airspace agent. The agent is written in Perl and retrieves WLAN information through SNMP discovery. The Airspace agent is designed to query data from the Airspace MIBs and was developed using the Cisco Catalyst 3850 switch with wireless controller functionality enabled and thin access points through the Ethernet PoE ports.

 

The following MIBs are used by the agent:

AIRSPACE-REF-MIB.mib
AIRSPACE-SWITCHING-MIB.mib
AIRSPACE-WIRELESS-MIB.mib
