SNMP_WLAN(3) BSD Library Functions Manual SNMP_WLAN(3) NAME
snmp_wlan -- wireless networking module for bsnmpd(1) LIBRARY
(begemotSnmpdModulePath."wlan" = /usr/lib/snmp_wlan.so) DESCRIPTION
The snmp_wlan module implements a private BEGEMOT-WIRELESS-MIB, which allows management of virtual wireless interfaces. The MIB defines objects similar to the state data and configuration capabilities of ifconfig(8) for configuring virtual wireless interfaces. Therefore one should consider adding write communities or loading the snmp_wlan module on systems where security is crucial. IMPLEMENTATION NOTES
A short description of the Tables and interesting objects in the MIB follows. wlanInterfaceTable The table is used for creation and deletion of virtual wireless interfaces. To add a new interface, a SET should be executed on the wlanIfaceName column with value the desired name of the interface. Next the parent interface must be set via wlanParentIfName column. Any optional parameters may be set via the wlanIfaceOperatingMode, wlanIfaceFlags, wlanIfaceBssid and wlanIfaceLocalAddress columns. To finally create the interface in the system, a SET with value of active(1) to wlanIfaceStatus column should be executed. To destroy a wireless interface a SET with value of destroy(6) to the relevant wlanIfaceStatus column should be executed. wlanIfParentTable The table contains information about the hardware capabilities of the parent of a wireless interface. wlanIfaceConfigTable The table is used to get or set various configuration parameters for a virtual wireless interface. Depending on the operating mode of the interface and the hardware capabilities of the underlying hardware interface, not all parameters and values may be sup- ported. wlanIfacePeerTable The table contains information about the associated stations for interfaces operating as access points, or the stations identified as neighbors in the IBSS for interfaces operating in adhoc mode. wlanIfaceChannelTable Information about the active channels for the wireless interfaces in the system. wlanIfRoamParamsTable The parameters that govern the roaming operation on the wireless interfaces. wlanIfTxParamsTable The parameters that govern the transmit operation on the wireless interfaces. wlanScanConfigTable The table that contains a configuration for channel scanning initiated via SNMP. wlanScanResultsTable The table contains the scan results from the last scan for each wireless interface on the system. wlanIfaceStatisticsTable Summary statistics for each wireless interface on the system. wlanWepInterfaceTable WEP configuration for the wireless interfaces on the system. wlanMACAccessControlTable Access Control configuration for wireless interfaces operating as access points. wlanMACAccessControlMACTable The table with Access Control MAC entries for which the configured Access Control Policy on wireless interfaces operating in Host AP mode is applied. wlanMACAccessControlMACStatus column is used to add or delete MAC ACL entries. A set with value create- AndGo(4) will add new entry, while with value destroy(6) will delete an existing one. wlanMeshRoutingConfig The subtree contains system configuration related to Wireless Mesh Routing. wlanMeshInterfaceTable The table contains information for wireless interfaces operating as wireless mesh points. wlanMeshNeighborTable The table contains information for the neighbors of wireless interfaces operating in mesh mode. wlanMeshRouteTable The mesh routing table for interfaces operating as mesh points, used for forwarding packets on a mesh network. wlanMeshRouteStatus column is used to add or delete entries in the mesh routing table for an interface. A set with value create- AndGo(4) will add new entry, while with value destroy(6) will delete an existing one. wlanMeshStatsTable Summary statistics for each virtual wireless interface operating as mesh point. wlanMeshHWMPConfig The subtree contains system configuration related to Hybrid Wireless Mesh Protocol. wlanHWMPInterfaceTable The table contains HWMP information for wireless interfaces operating in mesh mode. wlanMeshHWMPStatsTable Summary statistics for HWMP operation on interfaces operating as mesh points. RESTRICTIONS
Not all information or configuration in the MIBs is currently available in FreeBSD. The values of the following variables carry no informa- tion: wlanStatsReset FILES
/usr/share/snmp/defs/wlan_tree.def The description of the MIB tree implemented by snmp_wlan. /usr/share/snmp/mibs/BEGEMOT-WIRELESS-MIB.txt The private BEGEMOT-WIRELESS-MIB that is implemented by this module. SEE ALSO
