Nortel-Magellan-Passport-BridgeMIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

-- Vr/<string> Pp/<string> ClusterTbBridgePort
-- This component represents the functionality called Cluster Bridging. 
-- Cluster Bridging allows for MAC frames, carrying packets belonging a 
-- certain network protocol, to be bridged and routed at the same time. 
-- Also, it provides for a convenient way to manage the entire cluster of 
-- LANs, using a single attachment point to the cluster of LANs, the 
-- Cluster Bridge Port. To realize these features, the network protocol(s) 
-- should also be provisioned on same port as the Cluster Bridge Port. 
-- ClusterTbBridgePort represents a cluster of Tb LANs.

      spanning tree as an identifier this bridge port.
      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

   STATUS     mandatory
   DESCRIPTION
     "This attribute specifies the media type the frame must be in before it is 
      to be forwarded over the outbound supported WAN Bridge Protocol 
      Port. The attribute only applies to outbound Bridge Protocol Port.
      
      For supported bridge ports, if the attribute value remains set to the 
      default value of unaltered then there will be no frame conversion. When 
      the value is set to the value ethernetConv then all frames being 
      forwarded out the outbound WAN Port will be converted to ethernet 
      before forwarding takes place. The only outbound WAN medias that 
      currently support conversion are: FR (Frame Relay) and VNS. All other 
      medias will fail the Bridge Port semantic check when attempts are made 
      to alter this attribute. 
      
      The following is an example of what the user may be able to do. Frames 
      originating from a Token Ring are to be flooded out onto another Token 
      Ring and a Frame Relay Port. The token ring Outbound port performs 
      no translation, yet the FR Port has the outboundFrameMediaType 
      attribute set to ethernetConv which results in the frame being translated 
      into Ethernet format from Token Ring format before Frame Relay does 
      its encapsulation and transmits over the FR port."

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

      Escape routines exist for initializing, copying, and deleting port

      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

   DESCRIPTION
     "This attribute specifies the media type the frame must be in before it is 
      to be forwarded over the outbound supported WAN Bridge Protocol 
      Port. The attribute only applies to outbound Bridge Protocol Port.
      
      For supported bridge ports, if the attribute value remains set to the 
      default value of unaltered then there will be no frame conversion. When 
      the value is set to the value ethernetConv then all frames being 
      forwarded out the outbound WAN Port will be converted to ethernet 
      before forwarding takes place. The only outbound WAN medias that 
      currently support conversion are: FR (Frame Relay) and VNS. All other 
      medias will fail the Bridge Port semantic check when attempts are made 
      to alter this attribute. 
      
      The following is an example of what the user may be able to do. Frames 
      originating from a Token Ring are to be flooded out onto another Token 
      Ring and a Frame Relay Port. The token ring Outbound port performs 
      no translation, yet the FR Port has the outboundFrameMediaType 
      attribute set to ethernetConv which results in the frame being translated 
      into Ethernet format from Token Ring format before Frame Relay does 
      its encapsulation and transmits over the FR port."

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

      originating from a Token Ring are to be flooded out onto another Token 
      Ring and a Frame Relay Port. The token ring Outbound port performs 
      no translation, yet the FR Port has the outboundFrameMediaType

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

      no translation, yet the FR Port has the outboundFrameMediaType

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

-- Vr/<string> Pp/<string> SrsgBridgePort
-- This component represents a controlled method to allow exchange of 
-- explorer frames between source route (SR) and source route transparent 
-- (SRT) networks.The SrsgBridgePort provides a cross over point for 
-- explorer frames from the source route network into the source route 
-- gating logic and vice-versa. The source route gating performs required 
-- verification before forwarding the frames into the source route 
-- transparent network.
-- The SrsgBridgePort participates in the source route spanning tree to 
-- eliminate possible loops caused by multiple active cross over points on 
-- multiple bridges and to provide for fault tolerance of these cross over 
-- points. While enabled, source route spanning tree BPDUs are sent 
-- across the source route transparent network, through this cross over 
-- point and the gating logic. Note that these explorer frames cross over 
-- based on the port's stpPortState.
-- All route explorer frames (ARE) are exchanged regardless of the 
-- stpPortState. 
-- Spanning tree explorer frames (STE) are exchanged only if stpPortState 
-- has a value of Forwarding.
-- If stpPortState has a value of Blocking STE frames will be sent out on 
-- bridge ports that are operating in the same mode, i.e. no exchange across 
-- SR and SRT networks takes place. Nevertheless, SR spanning tree 
-- BPDUs are still sent across the SRT network. Note that the 
-- SrsgBridgePort and the TbsgBridgePort must be provisioned during the 
-- same provisioning session as one cannot function without the other.

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

   DESCRIPTION
     "This attribute specifies the media type the frame must be in before it is

      For supported bridge ports, if the attribute value remains set to the

      originating from a Token Ring are to be flooded out onto another Token 
      Ring and a Frame Relay Port. The token ring Outbound port performs 
      no translation, yet the FR Port has the outboundFrameMediaType

      Notes regarding portNum:
      
      Escape routines exist for initializing, copying, and deleting port 
      numbers. This is necessary because SNMP requires a unique port 
      instance identifier. The initPortNum escape routine sets the port number 
      to a value in the range 1-255 for this purpose. The setCopiedPortNum 
      escape routine exists to maintain the uniqueness of the port number in 
      cases when one port is copied to another. When a bridge port is deleted, 
      the releasePortNum escape routine places the port number being 
      released into a pending deletion state. This is because the port number 
      cannot be re-allocated until the port is truely deleted in the current view. 
      This is necessary since there is no guarantee of order when processing 
      changes to multiple protocol ports so without the pending deletion state, 
      the same port number could be temporarily assigned to two ports for a 
      short period of time.
      
      The portNum is set as component critical since bridging also uses the 
      port number as a key for indexing into its data structures. If a port is 
      deleted then re-added under the same protocol port, CAS treats the 
      change as a SET to the portNum attribute."

      For supported bridge ports, if the attribute value remains set to the

      originating from a Token Ring are to be flooded out onto another Token 
      Ring and a Frame Relay Port. The token ring Outbound port performs 
      no translation, yet the FR Port has the outboundFrameMediaType

-- domain specific spanning tree instances.
-- Individual spanning tree instances are indexed using the domain number. 
-- The domain numbers assigned are only unique to the bridge type so 
-- domain numbers may be shared between TransparentBridge and 
-- SourceRouteBridge.
-- Note that only 16 instances of this component are allowed and includes

-- This component represents the Spanning Tree Protocol for the bridge.

-- multiple domains in the network, bridging allows provisioning of 
-- domain specific spanning tree instances.
-- Individual spanning tree instances are indexed using the domain number. 
-- The domain numbers assigned are only unique to the bridge type so 
-- domain numbers may be shared between TransparentBridge and 
-- SourceRouteBridge.
-- Note that only 16 instances of this component are allowed and includes 
-- the backbone spanning tree instance.
-- The instance identifier of the SpanningTreeProtocol component is

      desired Lan is across a TB/SRT cloud, this entry would have the name 
      of the SrSeBridgePort. 
      The attribute portName is a string of the form 'BridgePortName-i', 
      where BridgePortName is the abbreviation of the corresponding bridge 
      port and i is the instance identifier of the ProtocolPort the bridge port is 
      provisioned under. For example a SourceRouteBridgePort provisioned 
      under ProtocolPort/MyPort would have a name SrBP-MyPort. Please 
      note that the attribute portName cannot have a value of TBP, FddiETb, 
      Tbse, Tbcl, Tbsr, Srsg, Tbsg.
