Expires in six months [Page 1] draft Supplemental ATM Management Objects Sept 1996 _2. _I_n_t_r_o_d_u_c_t_i_o_n This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes objects used for managing ATM-based interfaces, devices, networks and services in addition to those defined in the ATM MIB [1], to provide additional support for the management of: - ATM Switched Virtual Connections (SVCs) - ATM Permanent Virtual Connections (PVCs) This memo specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI, and semantically identical to the peer SNMPv1 definitions. This memo does not specify a standard for the Internet community. _3. _T_h_e _S_N_M_P_v_2 _N_e_t_w_o_r_k _M_a_n_a_g_e_m_e_n_t _F_r_a_m_e_w_o_r_k The SNMPv2 Network Management Framework consists of four major components. They are: 0 RFC 1442 [2] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. 0 STD 17, RFC 1213 [3] defines MIB-II, the core set of managed objects for the Internet suite of protocols. 0 RFC 1445 [4] which defines the administrative and other architectural aspects of the framework. 0 RFC 1448 [5] which defines the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. Expires in six months [Page 2] draft Supplemental ATM Management Objects Sept 1996 _4. _O_b_j_e_c_t _D_e_f_i_n_i_t_i_o_n_s Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. 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 also refer to the object type. _5. _O_v_e_r_v_i_e_w The purpose of this memo is to provide additional capabilities, not found in the ATM MIB [1], which are needed to manage ATM interfaces. This memo addresses the following areas: - ATM Switch Support - ATM Service Support - ATM Host Support _5._1. _B_a_c_k_g_r_o_u_n_d In addition to the MIB module defined in this memo, other MIB modules are necessary to manage ATM interfaces, links and cross-connects. Examples include MIB II for general system and interface management (RFC 1213 and RFC 1573), the DS3 or SONET MIBs for management of SONET and DS3 physical interfaces, and, as appropriate, MIB modules for applications that make use of ATM, such as SMDS [15] and LAN Emulation [14]. These MIB modules are outside the scope of this specification. This MIB module also requires the use of the ATM MIB module defined in [1]. ATM Endpoint applications such as ATM LAN Emulation or Classical IP-over-ATM Clients and Servers use ATM to establish SVC/PVC connections for exchanging control and data information. The agents of these ATM applications must provide the network manager with information on the SVC/PVCs in use Expires in six months [Page 3] draft Supplemental ATM Management Objects Sept 1996 and which applications are using them. The information can be made generic so as to apply to all ATM applications. This memo proposes extensions to the ATM MIB [1] in order to support this. The current specification of this supplemental ATM MIB is based on SNMPv2 SMI. _5._2. _I_m_p_o_r_t_a_n_t _D_e_f_i_n_i_t_i_o_n_s The following terms are defined here and used throughout this MIB: - Virtual Path Link (VPL) - Virtual Path Connection (VPC) - Virtual Path Segment (VP Segment) - Virtual Channel Link (VCL) - Virtual Channel Connection (VCC) - Virtual Channel Segment (VC Segment). _____ _______ _______ _______ _____ | |____| |____| |____| |____| | |Host1| |SwitchA| |SwitchB| |SwitchC| |Host2| | |____| |____| |____| |____| | |_____| |_______| |_______| |_______| |_____| |<----->| Virtual |<----->| Virtual Path Link Path Link |<------------Virtual Path Connection---------->| (between Host1 and Host2) |<--------------->| Virtual Path Segment (between SwitchA and SwitchC) Figure 1: Examples of Virtual Path Links, Virtual Path Connection, and Virtual Path Segment Expires in six months [Page 4] draft Supplemental ATM Management Objects Sept 1996 _____ _______ _______ _______ _____ | |____| |____| |____| |____| | |Host1|----|SwitchA|----|SwitchB|----|SwitchC|----|Host2| | |____| |____| |____| |____| | |_____| |_______| |_______| |_______| |_____| |<----->| Virtual |<----->| Virtual Channel Link Channel Link |<----------Virtual Channel Connection--------->| (between Host1 and Host2) |<--------------->| Virtual Channel Segment (between SwitchA and SwitchC) Figure 2: Examples of Virtual Channel Links, Virtual Channel Connection, and Virtual Channel Segment _5._3. _S_u_p_p_o_r_t_e_d _F_u_n_c_t_i_o_n_s The managed ATM objects are arranged as follows: Table Host Switch Service _____________________________________________________ atmSvcVcCrossConnectTable | | Y | Y | atmSvcVpCrossConnectTable | | Y | Y | atmSigTable | Y | Y | Y | atmSigSupportTable | | Y | Y | atmSigDescrParamTable | Y | | | atmIfAdminAddrTable | | Y | Y | atmVclAddrBindTable | Y | | | atmAddrVclTable | Y | Y | Y | atmVplStatTable | Y | Y | Y | atmVplLogicalPortTable | Y | Y | Y | atmVclStatTable | Y | Y | Y | atmVclGenTable | Y | Y | Y | atmInterfaceExtTable | Y | Y | Y | Expires in six months [Page 5] draft Supplemental ATM Management Objects Sept 1996 Table 1: MIB structure _5._3._1. _A_T_M _S_V_C _V_C _C_r_o_s_s _C_o_n_n_e_c_t _T_a_b_l_e This table provides the SVC VC Cross connection information.

The ATM logical port represents the interface of a VP tunnel, and each such interface may have zero or one signalling VCLs. An ATM switch often switch cells over an internal interface (a proprietary virtual interface), to and from an ATM application resides in the ATM switch. If such an interface has a signalling VCL, the atmSigTable must includes a row for the interface. Expires in six months [Page 8] draft Supplemental ATM Management Objects Sept 1996 Figure 4 gives an example of the signalling VCLs and their associated interfaces for an ATM switch. The cross-connecting of the signalling channels is done to allow the reading of AAL5 errors.

IF2 is the "ATM Logical Port" interface provided by the VP tunnel with VPI=44 on the physical interface. IF4 and IF5 are the ATM and AAL5 (respectively) internal sub-layer interfaces for VCLs terminating at the switch. It is assumed in this example that the ifIndex value for IF1 is 1, IF2 is 2, etc. There are 4 rows in the atmSigTable, therefore, indexed by their ifIndex Expires in six months [Page 9] draft Supplemental ATM Management Objects Sept 1996 values 1, 2, 3 and 4. In the case depicted: - On IF1, the VCL1 signalling channel can be used to set up connections over the interface address space with the exception of the VP with VPI=44. An entry exists in the atmVplTable with index ifIndex=1,atmVplVpi=44, and in the augmenting atmVplLogIfConfTable, atmVplLogIfDef=isLogicalIf(2), atmVplLogIfIndex=2. - On IF2, the VCL2 Signalling channel can set up VCs over the ATM Logical Port interface's address space (VPI=44, VCI range dictated by configuration). - On IF3, the VCL3 signalling channel can be used to set up VCs over the entire interface address space. Expires in six months [Page 10] draft Supplemental ATM Management Objects Sept 1996 The only VCLs depicted in the Figure 4 are those used for Signalling. External interface VCLs are cross-connected to VCLs at the proprietary interface. The rows show up in the ATM VCL table are: ifIndex, atmVclVpi, atmVclVci ============================= VCL1 1 0 5 VCL2 2 44 5 VCL3 3 0 5 VCL4 4 p1 c1 VCL5 4 p2 c2 VCL6 4 p3 c3 The p(i) and c(j) values for VPI/VCI on the VCLs on the proprietary interface indicate that these values are chosen by the switch software (versus the values dictated on the external interfaces). _5._3._3._1. _A_T_M _I_n_t_e_r_f_a_c_e _S_i_g_n_a_l_l_i_n_g _C_o_n_f_i_g_u_r_a_t_i_o_n _I_n_f_o_r_m_a_t_i_o_n A manager can configure the Signalling entity to run a specific signalling suit such as DSS2, ATM Forum UNI, PNNI or BICI. It can also dictate the side of the signalling. For example, if a signalling entity is configured to run ATM Forum UNI 3.1, it has to be told to run as the network side or the user side of the UNI. The objects atmSigConfigSigType and atmSigConfigSide are used for configuration and the objects atmSigActiveSigType and atmSigActiveSigSide are used for reading back the actual signalling configuration. The following table describes all the combinations of the configuration of the signalling entity: atmSigConfigSigType atmSigConfigSigSide ---------------- ---------------- autoConfig other ituDss2 user/network atmfUni3Dot0 user/network atmfUni3Dot1 user/network atmfUni4Dot0 user/network atmfIisp3Dot0 user/network atmfIisp3Dot1 user/network Expires in six months [Page 11] draft Supplemental ATM Management Objects Sept 1996 atmfPnni1Dot0 other atmfBici2Dot0 other When the value of the object atmSigConfigSigType is configured to autoConfig(2), the signalling type is determined via the ATM Forum ILMI auto-configuration procedures [22]. There is no need to set the signalling side since it should be a derived value. The PNNI and BICI interfaces are always symmetric so setting the signalling side is also not necessary. _5._3._3._2. _S_i_g_n_a_l_l_i_n_g _M_o_n_i_t_o_r_i_n_g _I_n_f_o_r_m_a_t_i_o_n To monitor the signalling entity, a few counters are provided. They are defined as: _5._3._3._2._1. _S_S_C_O_P _C_o_u_n_t_e_r_s This group contains information on the ATM SSCOP signalling layer and must be supported by signalling entities. _5._3._3._2._2. _U_n_s_u_p_p_o_r_t_e_d _S_e_r_v_i_c_e _F_a_i_l_u_r_e_s This group contains information on the setup failures that occur when setting up an ATM SVC. Maintaining counters for each individual signalling cause codes would result in a large number of counters. Instead, this memo uses an approach that lumps events into the following categories: - Route Unavailability Counter - Resources Unavailability Counter - Called Party Events Counter - Message Error Counter - Calling Party Events Counter - Timer Expiries Counter - Restart Activity Counter In addition, a Setup Attempts Counter was added to keep track of the number of Setup attempts made (both successful and unsuccessful). Setup attempts are counted both at the receiving and sending sides of the signalling entity. For example, the object atmSigDetectSetupAttempts counts the number of setup attempts Expires in six months [Page 12] draft Supplemental ATM Management Objects Sept 1996 detected on the interface and the object atmSigEmittSetupAttempts counts the number of setup attempts emitted from this interface. Thus, a switch will increment both the receiving and emitting counters when relaying a setup attemp. _5._3._3._2._3. _A_T_M _S_i_g_n_a_l_l_i_n_g _L_a_y_e_r _P_r_o_t_o_c_o_l _E_r_r_o_r_s This group contains information on the Protocol Errors that occur at the signalling layer when establishing an ATM SVC. _5._3._3._2._4. _U_N_I _S_i_g_n_a_l_l_i_n_g _S_u_b-_l_a_y_e_r _S_t_a_t_i_s_t_i_c_s Statistics per VCL are needed in order to find out the usage of VCL resources by ATM applications. Additionally, to monitor the usage and health of a UNI signalling entity, some counters are needed per UNI signalling entity. Two new objects are added to count the number of connections established. One for incoming SVCs and one for outgoing SVCs. Note that some counters do not apply to the proprietary virtual interface such as the atmSigSSCOPConEvents, atmSigSSCOPErrdPdus, atmSigSigMsgErrors and atmSigSigRestarts. _5._3._4. _A_T_M _U_N_I _S_V_C _I_n_f_o_r_m_a_t_i_o_n _E_l_e_m_e_n_t _S_u_p_p_o_r_t A number of Information Elements may or may not be supported by ATM switches or ATM Service. Hence, for trouble isolation it is important to keep track which particular Information Elements are supported. The corresponding group of objects must be supported by switches or networks supporting SVCs, and indicate whether the following Information Elements are enabled/disabled: 1) Calling party number 2) Calling party subaddress 3) Called party subaddress 4) Broadband high layer information 5) Broadband low layer information Expires in six months [Page 13] draft Supplemental ATM Management Objects Sept 1996 6) Broadband Repeat Indicator 7) AAL parameters The last parameter, Preferred Carrier Pre-Subscription, identifies the carrier to which intercarrier calls originated from this interface are routed when transit network selection information is not provided by the calling party. _5._3._5. _S_i_g_n_a_l_l_i_n_g _D_e_s_c_r_i_p_t_o_r _P_a_r_a_m_e_t_e_r _T_a_b_l_e This table extends the ATM VCL table of the ATM MIB [1] to include all other necessary signalling information as specified in both ATM Forum UNI Specifications [9] and [10]. A user can create an entry with all signalling parameters and later use that entry to specify the signalling characteristics of SVCs. Signalling attributes can be grouped into following categories: 1) ATM Adaptation Layer Parameters Information in this group are captured in the ATM Signalling Descriptor Parameter Table defined in this memo. Please refer to section 5.4.5.5 of [9] and [10]. 2) Broadband Bearer Capability Information in this group are captured by the ATM Signalling Descriptor Parameter Table defined in this memo.

ATM Local Address identifies the local endpoint of the VCL represented by this agent. While, the ATM Remote address represents the address of the ATM application at the other end of the VCL. _5._3._8. _A_T_M _A_d_d_r_e_s_s _t_o _V_P_I/_V_C_I _M_a_p_p_i_n_g _T_a_b_l_e This table provides an alternative way to retrieve the atmVclTable.

The VPL cell counters count the valid ATM cells. The valid ATM cells include the user and OAM cells but exclude the physical layer (e.g. idle cells) and unassigned cells. Cells coming in to an ATM managed system are counted differently with the high Cell Loss Priority (CLP=0) or low Cell Loss Priority (CLP=1). The cells are tagged, passed or discarded depending on the incoming CLP value and the policed cell rate by the "traffic policing" entity in the ATM managed system. Refer to [9] and [10] for the description of the traffic policing. In the switch where the traffic policing is not supported, cells are passed or discarded depending on the bandwidth of the switching fabric. The Output Tagged Cells counter, in this case, is always zero. _______________ | ATM Managed | Input | System | Output CLP=0 cells| | CLP=0 cells Expires in six months [Page 15] draft Supplemental ATM Management Objects Sept 1996 ---------->| |-----------> CLP=1 cells| (traffic | CLP=1 cells ---------->| policing |-----------> | entity) | Tagged cells (CLP=1) |_____________|-----------> |Discard | Discard |CLP=0 | CLP=1 |cells | cells | | V V Figure 5. ATM Cell Counters per VPL In this table, cells coming into and out of the managed ATM system are counted as the total number of cells and the cells with the CLP=0. The CLP=1 counter is derived by substracting CLP=0 cells from the total cells. In addition, cells that are tagged on the output are also counted. The output CLP=1 cells equals to the total cells out count minus both the CLP=0 cells and the tagged cells.

Figure 6 illustrates such a VP Tunnel. Note: the "ATM Logical Port" interface is more of a logical port, compared with an interface of type "ATM" which is more of a physical port that provides for the transport of many VP and VC connections between adjacent devices.

Figure 6 shows only one VP tunnel, but there can be multiple VP tunnels over the same physical interface. A particularly useful VP tunnel scenario is tunneling across a public network that does not support signalling. In Figure 6 above, assume Switches A and B are private switches that signal over the VP to set up connections transparently through the public network. The public network would just transport a PVC VP between the two switches. Because the VP Tunnel constitutes an interface between two ATM devices that are not necessarily physically adjacent, most of the management information pertaining to the interface may differ for the tunnel, including: - active VPI/VCI fields (the tunnel may be a subset of the parent interface). - maximum number of VCCs - configured VCCs - ILMI VPI/VCI values - ATM address type - ATM administrative address - received/transmitted cells.

To create an Atm Logical Port interface via SNMP: - Create a VPL (e.g., VPI=a on an existing ATM interface which has ifIndex=x) in the atmVplTable. - Set the object atmVplLogicalPortDef to isLogicalIf. A new row in the ifTable is then created by the agent, with ifIndex=y, to represent the ATM Logical Port interface. The object atmVplLogicalPortIndex is also set to y by the agent to represent the ifIndex value of the ATM Logical Port interface. - The ifEntry values are set for the ATM Logical Port interface (ifIndex=y) as discussed in RFC 1695, with the following exceptions: * ifType - a new enumerated value of "80" was added to IANAifType, specifying an "ATM Logical Port" interface. * ifSpeed - The total bandwidth in bits per second for use by the ATM layer.
