31.Dt SNMP_WLAN 3
32.Os
33.Sh NAME
34.Nm snmp_wlan
35.Nd "wireless networking module for"
36.Xr bsnmpd 1
37.Sh LIBRARY
38.Pq begemotSnmpdModulePath."wlan" = "/usr/lib/snmp_wlan.so"
39.Sh DESCRIPTION
40The
41.Nm snmp_wlan
42module implements a private BEGEMOT-WIRELESS-MIB, which allows
43management of virtual wireless interfaces.
44The MIB defines objects similar to the state data and configuration capabilities of
45.Xr ifconfig 8
46for configuring virtual wireless interfaces.
47Therefore one should consider adding write communities or loading the
48.Nm
49module on systems where security is crucial.
50.Sh IMPLEMENTATION NOTES
51A short description of the Tables and interesting objects in the MIB follows.
52.Bl -tag -width "XXXXXXXXX"
53.It Va wlanInterfaceTable
54The table is used for creation and deletion of virtual wireless interfaces.
55To add a new interface, a SET should be executed on the
56.Va wlanIfaceName
57column with
58value the desired name of the interface.
59Next the parent interface must be set via
60.Va wlanParentIfName
61column.
62Any optional parameters may be set via the
63.Va wlanIfaceOperatingMode ,
64.Va wlanIfaceFlags ,
65.Va wlanIfaceBssid
66and
67.Va wlanIfaceLocalAddress
68columns.
69To finally create the interface in the system, a SET with value of active(1) to
70.Va wlanIfaceStatus
71column should be executed.
72To destroy a wireless interface a SET with value of destroy(6) to the relevant
73.Va wlanIfaceStatus
74column should be executed.
75.It Va wlanIfParentTable
76The table contains information about the hardware capabilities of the parent of
77a wireless interface.
78.It Va wlanIfaceConfigTable
79The table is used to get or set various configuration parameters for a virtual
80wireless interface.
81Depending on the operating mode of the interface and the hardware capabilities
82of the underlying hardware interface, not all parameters and values may be supported.
83.It Va wlanIfacePeerTable
84The table contains information about the associated stations for interfaces
85operating as access points, or the stations identified as neighbors in the IBSS
86for interfaces operating in adhoc mode.
87.It Va wlanIfaceChannelTable
88Information about the active channels for the wireless interfaces in the system.
89.It Va wlanIfRoamParamsTable
90The parameters that govern the roaming operation on the wireless interfaces.
91.It Va wlanIfTxParamsTable
92The parameters that govern the transmit operation on the wireless interfaces.
93.It Va wlanScanConfigTable
94The table that contains a configuration for channel scanning initiated via SNMP.
95.It Va wlanScanResultsTable
96The table contains the scan results from the last scan for each wireless
97interface on the system.
98.It Va wlanIfaceStatisticsTable
99Summary statistics for each wireless interface on the system.
100.It Va wlanWepInterfaceTable
101WEP configuration for the wireless interfaces on the system.
102.It Va wlanMACAccessControlTable
103Access Control configuration for wireless interfaces operating as access points.
104.It Va wlanMACAccessControlMACTable
105The table with Access Control MAC entries for which the configured Access
106Control Policy on wireless interfaces operating in Host AP mode is applied.
107.Va wlanMACAccessControlMACStatus
108column is used to add or delete MAC ACL entries.
109A set with value createAndGo(4) will add new entry, while with value destroy(6)
110will delete an existing one.
111.It Va wlanMeshRoutingConfig
112The subtree contains system configuration related to Wireless Mesh Routing.
113.It Va wlanMeshInterfaceTable
114The table contains information for wireless interfaces operating as wireless
115mesh points.
116.It Va wlanMeshNeighborTable
117The table contains information for the neighbors of wireless interfaces
118operating in mesh mode.
119.It Va wlanMeshRouteTable
120The mesh routing table for interfaces operating as mesh points, used for
121forwarding packets on a mesh network.
122.Va wlanMeshRouteStatus
123column is used to add or delete entries in the mesh routing table for an
124interface.
125A set with value createAndGo(4) will add new entry, while with value destroy(6)
126will delete an existing one.
127.It Va wlanMeshStatsTable
128Summary statistics for each virtual wireless interface operating as mesh point.
129.It Va wlanMeshHWMPConfig
130The subtree contains system configuration related to Hybrid Wireless Mesh
131Protocol.
132.It Va wlanHWMPInterfaceTable
133The table contains HWMP information for wireless interfaces operating in mesh
134mode.
135.It Va wlanMeshHWMPStatsTable
136Summary statistics for HWMP operation on interfaces operating as mesh points.
137.El
138.Sh RESTRICTIONS
139Not all information or configuration in the MIBs is currently available in FreeBSD.
140The values of the following variables carry no information:
141.Bl -tag -width "XXXXXXXXX"

143.El
144.Sh FILES
145.Bl -tag -width "XXXXXXXXX"
146.It Pa /usr/share/snmp/defs/wlan_tree.def
147The description of the MIB tree implemented by
148.Nm .
149.It Pa /usr/share/snmp/mibs/BEGEMOT-WIRELESS-MIB.txt
150The private BEGEMOT-WIRELESS-MIB that is implemented by this module.
