SNMP_BRIDGE(3)	       FreeBSD Library Functions Manual		SNMP_BRIDGE(3)

NAME
     snmp_bridge -- bridge module for snmpd

LIBRARY
     (begemotSnmpdModulePath."bridge" =	/usr/lib/snmp_bridge.so)

DESCRIPTION
     The snmp_bridge module implements the BRIDGE-MIB as standardized in RFC
     4188, the RSTP-MIB	standardized in	RFC4318	and a private BEGEMOT-BRIDGE-
     MIB, which	allows management of multiple bridge interfaces.  Most of the
     objects defined in	the private BEGEMOT-BRIDGE-MIB are duplicates of the
     original objects defined by the standard BRIDGE-MIB, but the private MIB
     also defines additional objects which make	the functionality of
     snmp_bridge similar to ifconfig(8)	for configuring	bridge interfaces.
     Therefore one should consider adding write	communities or loading the
     snmp_bridge module	on systems where security is crucial.

IMPLEMENTATION NOTES
     The additional objects to configure a bridge are:

     begemotBridgeBaseStatus
		Bridge interfaces can be created and destroyed via this	ob-
		ject.  SNMP SET	operations with	the following values are al-
		lowed:

		createAndWait  will attempt to create a	bridge interface with
			       the name	given by the table index.

		createAndGo    will attempt to create a	bridge interface with
			       the name	given by the table index and set the
			       status of the interface to "active/up".

		destroy	       will attempt to destroy the bridge interface.

     begemotBridgeBaseSpanEnabled
		A SNMP SET operation on	this object is only successful if the
		corresponding port has not been	added as member	of the bridge
		interface on the system.

     begemotBridgeBasePortStatus
		SNMP SET operations with the following values are allowed:

		createAndWait  will create a new row for the bridge member in
			       the SNMP	begemotBridgeBasePortTable but will
			       not try to commit the information to the	sys-
			       tem.

		active	       will attempt to commit the information to the
			       system and will be successful only if a value
			       for begemotBridgeBaseSpanEnabled	has been SET
			       already.

		destroy	       will attempt to remove the interface from the
			       system bridge interface.

     begemotBridgeBasePortPrivate
		This object controls a bridge interface	flag called PRIVATE
		where any private port can not communicate with	another	pri-
		vate port.

RESTRICTIONS
     Not all information in the	MIBs is	currently available in FreeBSD.	 The
     following variables carry no information:

     dot1dBasePortCircuit

     dot1dBasePortDelayExceededDiscards

     dot1dBasePortMtuExceededDiscards

     begemotBridgeBasePortDelayExceededDiscards

     begemotBridgeBasePortMtuExceededDiscards
