BEGEMOT-BRIDGE-MIB: View SNMP OID List / Download MIB

The Begemot MIB for managing bridge interfaces.

The begemotBridgeNewRoot trap indicates that one of the bridge interfaces on the sending agent's device has become the new root of the spanning tree topology it is participating in.

A begemotBridgeTopologyChange trap is send when a member port on one of the bridge interfaces, monitored by the agent, transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a begemotBridgeNewRoot trap is sent for the same transition.

If the Spanning Tree Protocol is administratively disabled on the port, this object shall have value disabled(1). A value of broken(6) does not correspond to any legal state of a port, and if present should indicate error in the operation of either the Spanning Tree Protocol implementation running on the device or the management entity. Enumeration: 'listening': 3, 'disabled': 1, 'broken': 6, 'learning': 4, 'forwarding': 5, 'blocking': 2.

When operating in RSTP (version 2) mode, writing true(1) to this object forces this port to transmit RSTP BPDUs. Any other operation on this object has no effect and it always returns false(2) when read.

The administrative value of the Edge Port parameter. A value of true(1) indicates that this port should be assumed as an edge-port, and a value of false(2) indicates that this port should be assumed as a non-edge-port. Setting this object will also cause the corresponding instance of begemotBridgeStpPortOperEdgePort to change to the same value. Note that even when this object's value is true, the value of the corresponding instance of begemotBridgeStpPortOperEdgePort can be false if a BPDU has been received. The value of this object MUST be retained across reinitializations of the management system.

The operational value of the Edge Port parameter. The object is initialized to the value of the corresponding instance of begemotBridgeStpPortAdminEdgePort. When the corresponding instance of begemotBridgeStpPortAdminEdgePort is set, this object will be changed as well. This object will also be changed to false on reception of a BPDU.

The administrative point-to-point status of the LAN segment attached to this port, using the enumeration values of the IEEE 802.1w clause. A value of forceTrue(0) indicates that this port should always be treated as if it is connected to a point-to-point link. A value of forceFalse(1) indicates that this port should be treated as having a shared media connection. A value of auto(2) indicates that this port is considered to have a point-to-point link if it is an Aggregator and all of its members are aggregatable, or if the MAC entity is configured for full duplex operation, either through auto-negotiation or by management means. Manipulating this object changes the underlying adminPortToPortMAC. The value of this object MUST be retained across reinitializations of the management system. Enumeration: 'forceFalse': 1, 'forceTrue': 0, 'auto': 2.

The operational point-to-point status of the LAN segment attached to this port. It indicates whether a port is considered to have a point-to-point connection. If adminPointToPointMAC is set to auto(2), then the value of operPointToPointMAC is determined in accordance with the specific procedures defined for the MAC entity concerned, as defined in IEEE 802.1w, clause 6.5. The value is determined dynamically; that is, it is re-evaluated whenever the value of adminPointToPointMAC changes, and whenever the specific procedures defined for the MAC entity evaluates a change in its point-to-point status.

The administratively assigned value for the contribution of this port to the path cost of paths toward the spanning tree root. Writing a value of '0' assigns the automatically calculated default Path Cost value to the port. If the default Path Cost is being used, this object returns '0' when read. This complements the object begemotBridgeStpPortPathCost or begemotBridgeStpPortPathCost32, which returns the operational value of the path cost. The value of this object MUST be retained across reinitializations of the management system.
