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
object. SNMP SET operations with the following values are
allowed:
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 system.
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.
following variables carry no information:
dot1dBasePortCircuit
dot1dBasePortDelayExceededDiscards
dot1dBasePortMtuExceededDiscards
begemotBridgeBasePortDelayExceededDiscards
begemotBridgeBasePortMtuExceededDiscards
