John Flick Expires June 18, 1996 [Page 1] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 1. Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing network repeaters based on IEEE 802.12. 2. Object Definitions Management information is viewed as a collection of managed objects, residing in a virtual information store, termed the Management Information Base (MIB). Collections of related objects are defined in MIB modules. MIB modules are written using a subset of Abstract Syntax Notation One (ASN.1) [1] termed the Structure of Management Information (SMI) [2]. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to refer to the object type. John Flick Expires June 18, 1996 [Page 2] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 3. Overview Instances of these object types represent attributes of an IEEE 802.12 repeater, as defined by Section 12, "RMAC Protocol" in IEEE Standard 802.12-1995 [6]. The definitions presented here are based on Section 13, "Layer management functions and services", and Annex C, "GDMO Specifications for Demand Priority Managed Objects" of IEEE Standard 802.12-1995 [6]. Implementors of these MIB objects should note that the IEEE document explicitly describes (in the form of Pascal pseudocode) when, where, and how various repeater attributes are measured. The IEEE document also describes the effects of repeater actions that may be invoked by manipulating instances of the MIB objects defined here. The counters in this document are defined to be the same as those counters in IEEE Standard 802.12-1995, with the intention that the same instrumentation can be used to implement both the IEEE and IETF management standards. 3.1. MAC Addresses All representations of MAC addresses in this MIB module are in "canonical" order defined by 802.1a, i.e., as if it were transmitted least significant bit first. This is true even if the repeater is operating in token ring framing mode, which requires MAC addresses to be transmitted most significant bit first. John Flick Expires June 18, 1996 [Page 3] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 3.2. IEEE 802.12 Training Frames Training frames are special MAC frames that are used only during link initialization. Training frames are initially constructed by the device at the lower end of a link. The training frame format is as follows: +----+----+------------+--------------+----------+-----+ | DA | SA | Req Config | Allow Config | Data | FCS | +----+----+------------+--------------+----------+-----+ DA = destination address (six octets) SA = source address (six octets) Req Config = requested configuration (2 octets) Allow Config = allowed configuration (2 octets) Data = data (594 to 675 octets) FCS = frame check sequence (4 octets) Training frames are always sent with a null destination address. To pass training, an end node must use its source address in the source address field of the training frame. A repeater may use a non-null source address if it has one, or it may use a null source address. John Flick Expires June 18, 1996 [Page 4] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 The requested configuration field allows the device at the lower end of a link to inform the device at the upper end of the link about itself and to request configuration options. The training response frame from the device at the upper end of the link contains the requestor's requested configuration from the training request frame. The currently defined format of the requested configuration field as defined in the IEEE Standard 802.12-1995 standard is shown below. Please refer to the most current version of the IEEE document for a more up to date description of this field. In particular, the reserved bits may be used in later versions of the standard. First Octet: Second Octet: 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ |v|v|v|r|r|r|r|r| |r|r|r|F|F|P|P|R| +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ vvv: The version of the 802.12 training protocol with which the training initiator is compliant. The current version is 100. r: Reserved bits (set to zero) FF: 00 = frameType88023 01 = frameType88025 10 = reserved 11 = frameTypeEither PP: 00 = singleAddressMode 01 = promiscuousMode 10 = reserved 11 = reserved R: 0 = the training initiator is an end node 1 = the training initiator is a repeater John Flick Expires June 18, 1996 [Page 5] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 The allowed configuration field allows the training responder to respond with the allowed configuration. The training initiator sets the contents of this field to all zero bits. The training responder sets the allowed configuration field as follows: First Octet: Second Octet: 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ |v|v|v|D|C|N|r|r| |r|r|r|F|F|P|P|R| +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ vvv: The version of the 802.12 training protocol with which the training responder is compliant. The current version is 100. D: 0 = No duplicate address has been detected. 1 = Duplicate address has been detected C: 0 = The requested configuration is compatible with the network. 1 = The requested configuration is not compatible with the network. In this case, the FF, PP, and R bits indicate the configuration that would be allowed. N: 0 = Access will be allowed, providing the configuration is compatible (C = 0). 1 = Access is not granted because of security restrictions r: Reserved bits (set to zero) FF: 00 = frameType88023 will be used 01 = frameType88025 will be used 10 = reserved 11 = reserved PP: 00 = singleAddressMode 01 = promiscuousMode 10 = reserved 11 = reserved R: 0 = Requested access as an end node is allowed 1 = Requested access as a repeater is allowed Again, note that the most recent version of the IEEE 802.12 standard should be consulted for the most up to date definition of the requested configuration and allowed configuration fields. The data field contains between 594 and 675 octets and is filled in by the training initiator. The first 55 octets may be used for vendor specific protocol information. The remaining octets are all zeros. The length of the training frame combined with the requirement that 24 consecutive training frames be received without error to complete training ensures that marginal links will not John Flick Expires June 18, 1996 [Page 6] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 complete training. 3.3. Structure of the MIB Objects in this MIB are arranged into MIB groups. Each MIB group is organized as a set of related objects. 3.3.1. The Basic Group Definitions This group contains the objects which are applicable to all repeaters. It contains status, parameter and control objects for each repeater within the managed system, for the port groups within the system, and for the individual ports themselves. 3.3.2. The Monitor Group Definitions This group contains monitoring statistics for each repeater within the system and for individual ports. 3.3.3. The Address Tracking Group Definitions This group contains objects for tracking the MAC addresses of the DTEs attached to the ports within the system. 3.4. Relationship to other MIBs It is assumed that a repeater implementing this MIB will also implement (at least) the 'system' group defined in MIB-II [5]. 3.4.1. Relationship to the 'system' group In MIB-II, the 'system' group is defined as being mandatory for all systems such that each managed entity contains one instance of each object in the 'system' group. Thus, those objects apply to the entity even if the entity's sole functionality is management of repeaters. 3.4.2. Relationship to the 'interfaces' group In MIB-II, the 'interfaces' group is defined as being mandatory for all systems and contains information on an entity's interfaces, where each interface is thought of as being attached to a the Internet suite of protocols.) John Flick Expires June 18, 1996 [Page 7] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 This MIB uses the notion of ports on a repeater. The concept of a MIB-II interface has NO specific relationship to a repeater's port. Therefore, the 'interfaces' group applies only to the one (or more) network interfaces on which the entity managing the repeater sends and receives management protocol operations, and does not apply to the repeater's ports. 3.5.

The actual set of training configurations that will be allowed to succeed on a port is the intersection of what the hardware will support and what is administratively allowed. The above requirement on what values may be set to this object says that the intersection of what is supported and what is allowed must be non-empty. In other words, it must not result in a situation in which nothing would be allowed to train on that port. However, a value can be set to this object as long as the combination of this object and what is supported by the hardware would still leave at least one configuration that could successfully train on the port."

It defines objects which allow a network management application to instruct an agent to watch for a given MAC address and report which port it was seen on. Only one address search can be in progress on each repeater at any one time. Before starting an address search, a management application should obtain 'ownership' of the entry in vgRptrAddrSearchTable for the repeater that is to perform the search. This is accomplished with the vgRptrAddrSearchLock and vgRptrAddrSearchStatus as follows: try_again: get(vgRptrAddrSearchLock, vgRptrAddrSearchStatus) while (vgRptrAddrSearchStatus != notInUse) { /* Wait for objects to be available */ short delay get(vgRptrAddrSearchLock, vgRptrAddrSearchStatus) John Flick Expires June 18, 1996 [Page 39] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 } /* Try to claim map objects */ lock_value = vgRptrAddrSearchLock if ( set(vgRptrAddrSearchLock = lock_value, vgRptrAddrSearchStatus = inUse, vgRptrAddrSearchOwner = 'my-address') == FAILURE) /* Another manager got the lock */ goto try_again /* I have the lock */ set(vgRptrAddrSearchAddress = ) wait for vgRptrAddrSearchState to change from none if (vgRptrAddrASearchState == single) get (vgRptrAddrSearchGroup, vgRptrAddrSearchPort) /* release the lock, making sure not to overwrite anyone else's lock */ set (vgRptrAddrSearchLock = lock_value+1, vgRptrAddrSearchStatus = notInUse, vgRptrAddrSearchOwner = '') A management station first retrieves the values of the appropriate instances of the vgRptrAddrSearchLock and vgRptrAddrSearchStatus objects, periodically repeating the retrieval if necessary, until the value of vgRptrAddrSearchStatus is 'notInUse'. The management station then tries to set the same instance of the vgRptrAddrSearchLock object to the value it just retrieved, the same instance of the vgRptrAddrSearchStatus object to 'inUse', and the corresponding instance of vgRptrAddrSearchOwner to a value indicating itself. If the set operation succeeds, then the management station has obtained ownership of the vgRptrAddrSearchEntry, and the value of vgRptrAddrSearchLock is incremented by the agent (as per the semantics of TestAndIncr). Failure of the set operation indicates that some other manager has obtained ownership of the vgRptrAddrSearchEntry. Once ownership is obtained, the management station John Flick Expires June 18, 1996 [Page 40] Internet Draft IEEE 802.12 Repeater MIB December 18 1995 can proceed with the search operation. Note that the agent will reset vgRptrAddrSearchStatus to 'notInUse' if it has been in the 'inUse' state for an abnormally long period of time, to prevent a misbehaving manager from permanently locking the entry. It is suggested that this timeout period be between one and five minutes.
