CHAPTER 1 INTRODUCTION This manual is for system administrators responsible for configuring, monitoring, and maintaining the ELS10-26. Much of the configuration of the ELS10-26 needs to be done using an SNMP-based network management station. This manual contains the SNMP MIB variables you may need to configure, monitor, and manage your ELS10-26. You should use this manual with the ELS10-26 User Guide and with the documentation provided with your NMS. The contents of each chapter are described below.
Introduction 1.1 RELATED DOCUMENTATION You may need to refer to the following Cabletron documentation: • ELS10-26 User Guide – contains installation, configuration, and management instructions for the ELS10-26. It also describes how to use the Local Console Manager (LCM), which is a non-intelligent terminal interface to the ELS10-26. If you need internetworking reference material, you may find the following books helpful: • Interconnections, Bridges and Routers, Radia Perlman, Addison Wesley © 1992.

Introduction 1.3 DOCUMENT CONVENTIONS The following conventions are used throughout this document: LCM commands, prompts, and information displayed by the computer appear in Courier typeface, for example: Current Number of Learned Addresses: 133 Information that you enter appears in Courier bold typeface, for example: ELS10-26 >status Information that you need to enter with a command is enclosed in angle brackets < >.
Introduction 1.4 SNMP PRIMITIVES The major software interface between the NMS and ELS10-26 consists of one simple mechanism – the exchange of SNMP (Simple Network Management Protocol, RFC 1157) datagrams over any available physical media. The following restrictions apply: • All datagrams must obey SNMP format. • All datagrams must be sent via UDP and IP. Thus, all datagrams will have UDP and IP headers. • Datagrams may be sent over any of the following physical media: - Ethernet/802.
Introduction 1.5 MIB PRIMITIVE TYPES The MIB definitions in this document may reference the primitive types that are described in the Structure and Identification of Management Information for TCP/IP-based Internets, RFC 1155. RFC 1155 is based on the Specification of Abstract Syntax Notation One, ASN.1. The primitive types are described in Table 1-1.
Introduction 1.6 USER FUNCTIONS The SNMP primitives may be used to accomplish the following functions: • Obtain the ELS10-26’s current value of certain parameters - the NMS uses the GetRequest or GetNextRequest PDU, and the ELS10-26 responds with a GetResponse PDU. If the NMS issues a GetRequest for an unsupported parameter, the ELS10-26 sends a GetResponse with a noSuchName ErrorStatus1. If the NMS issues a GetNextRequest for an unsupported parameter, the ELS10-26 skips to the next object.
Introduction The ELS10-26 implements two non-standard features with respect to the SNMP SetRequest: • The variable bindings within a SetRequest are sometimes processed sequentially rather than simultaneously. For example, if a SetRequest contains two parameters with an incorrect value specified for the second parameter, the ELS10-26 returns a badValue error to the NMS; however, the ELS10-26 may have updated its value for the first parameter.
Introduction 1.7 NAVIGATING THROUGH THE MIBTREE STRUCTURE The MIB structure is a hierarchical tree structure. Each MIB variable has a numeric value that indicates its place in the hierarchy. The structure was originally created, and is still maintained by the International Organization for Standardization (ISO) and the International Telecommunications Union (ITU), two international standards organizations.
Introduction iso 1 org 3 dod 6 internet 1 mgmt 2 private 4 experimental 3 enterprise 1 mib-2 1 system 1 interfaces 2 Figure 1-1 sigma 97 add trans 3 ip 4 ...... rdbmsMIB 39 MIB Hierarchical Structure Table 1-2 provides the branch structure that is under MIB-II. To reach any of the MIB-II objects you would start with the prefix 1.3.6.1.2.1. For example, to reach an object in the system group, you would start with 1.3.6.1.2.1.1.
Introduction The zero at the end (.0), indicates that this is a single instance, and that only one value can be returned. Whenever you are looking for a variable with only one value, you must include the .0 at the end. Some variables may have multiple values, such as an IP address and an associated port number. Table 1-2 MIB-II Group Descriptions MIB-II Group Number (1.3.6.1.2.1.
Introduction The Cabletron MIB is under the private enterprise MIB branch. To identify a variable in the Cabletron MIB, you would start with the private enterprise prefix of 1.3.6.1.4.1, and add the specific Cabletron ID of 97. The result, 1.3.6.1.4.1.97, is the complete prefix for a Cabletron MIB variable. You would then add the specific object ID to complete the MIB variable.
Introduction 1.8 TFTP TFTP (Trivial File Transfer Protocol, RFC 1350) is used for: • Distribution of new software. • Bulk retrieval of all of the parameters of a ELS10-26. • Bulk setting of all of the parameters of a ELS10-26. TFTP has no inherent security provision; however, all files have special data encryption, and the ELS10-26 will reject files that have not been encrypted.
Introduction is recommended if you need to go back to the version of software that is currently being executed by the ELS10-26. 3. Tell TFTP to transfer (“put”) the first file, (dnld_hdr). 4. Wait one minute, or until the ELS10-26 sends the SNMP Trap described in the swdis branch of SMC’s private MIB. (The Trap will be sent when the ELS10-26 is ready for the second file, which will be somewhat shorter than three minutes.) 5. Tell TFTP to transfer the second file, (dnld_software).
Introduction 1.8.1 Retrieving All Parameters TFTP is used for retrieval of the parameters of an ELS10-26, as follows: 1. Start TFTP (as described earlier). TFTP must be told the IP address of the remote host (i.e., the ELS10-26), and the file transfer mode (which must be “binary”). 2. Tell TFTP to retrieve (i.e., “get”) the ELS10-26’s Configuration file (i.e., file name “config”). 3. After about ten seconds, the TFTP operation will complete. 1.8.
Introduction 1.9 ADDITIONAL INTERFACES In addition to SNMP and TFTP, the ELS10-26 employs the following protocols, as part of its software interface with an NMS: • UDP - User Datagram Protocol, RFC 768. • IP - Internet Protocol, RFC 791. • ARP - Ethernet Address Resolution Protocol, RFC 826. • RARP - Reverse Address Resolution Protocol, RFC 903. RARP is only used when no IP addresses have been assigned to the ELS10-26.
CHAPTER 2 TCP/IP MIB-II The ELS10-26 supports the TCP/IP MIB-II, as defined by Management Information Base for Network Management of TCP/ IP-based Internets MIB-II, RFC 1213 (K. McCloghrie, editor), dated March 1991. The MIB is divided into groups of parameters. The individual groups are described in the subsections below. You may want to refer to the actual TCP/IP MIB, since this document paraphrases the standard MIB in order to provide ELS10-26-related descriptions.
TCP/IP MIB-II the Cabletron MIB sysID object, i.e., {1 3 6 1 4 1 97 5 7}. Special versions of the ELS10-26, made for third-party vendors may use different values for sysID. sysUpTime TimeTicks Read-Only {system 3} The time, in centiseconds, since the ELS10-26 was last booted. sysContact DisplayString Read-Write {system 4} The name and address of the contact person for the ELS10-26. sysName DisplayString Read-Write {system 5} The Internet name of the contact person for the ELS10-26.
TCP/IP MIB-II ifNumber Integer Read-Only {interfaces 1} The number of ports (whether alive or dead), including the UART. ifTable Not Accessible {interfaces 2} A list of interface entries; one per port (ifNumber in total). ifEntry Not Accessible {ifTable 1} A set of objects for an interface entry. The individual components are described below. ifIndex Integer Read-Only {ifEntry 1} The port number, beginning with 1 for the first port. This number always matches the instance of the ifEntry.
TCP/IP MIB-II ifDescr DisplayString Read-Only {ifEntry 2} A textual description of the port. One of the following text strings: • Ethernet/802.3 TP • Network Management Port (this is the UART port) • Fast Ethernet/802.3u TP (twisted pair connection) • Fast Ethernet/802.3u FX (fiber connection) • Fast Ethenet/802.3u T4 (2 twisted pairs, category 5) ifType Integer Read-Only {ifEntry 3} The type of the port, i.e., one of the following: • (6) - ethernet-csmacd • (23) - ppp (for the UART port).
TCP/IP MIB-II ifPhysAddress Physical Address Read-Write1 {ifEntry 6} The MAC address of the port. For the UART port, this field should be an octet string of zero length. ifAdminStatus Integer Read-Write {ifEntry 7} The desired state of the port, i.e.
TCP/IP MIB-II ifInOctets Counter Read-Only {ifEntry 10} The total number of bytes received on the port, counting the MAC header and FCS, but not counting the bytes in packets that were rejected due to hardware errors. All counters are 32-bit wide wrap-around counters which can only be reset by restarting the port or by rebooting the ELS10-26. ifInUcastPkts Counter Read-Only {ifEntry 11} The number of non-multicast packets received by the port, regardless of the packet’s outcome (i.e.
TCP/IP MIB-II ifOutOctets Counter Read-Only {ifEntry 16} The total number of bytes transmitted out the port, counting the MAC header and FCS. ifOutUcastPkts Counter Read-Only {ifEntry 17} The number of non-multicast packets transmitted out the port, regardless of whether or not hardware transmission errors were encountered.
TCP/IP MIB-II ifOutQLen Gauge Read-Only {ifEntry 21} The maximum length ever obtained by the port’s outbound packet queue (in packets) is not available, so this value is always one. ifSpecific Object Identifier Read-Only {ifEntry 22} The object identifier of the MIB for the type of port, i.e., one of the following: {dot3} for Ethernet ports (dot3 is defined later, as {transmission 7}). {ppp} for the UART (ppp is defined later, as {experimental 18}). 2.
TCP/IP MIB-II atTable Not Accessible {at 1} atEntry Not Accessible {atTable 1} atIfIndex Integer Read-Write {atEntry 1} All GetResponse PDUs indicate a noSuchName ErrorStatus. atPhysAddress Physical Address Read-Write {atEntry 2} All GetResponse PDUs indicate a noSuchName ErrorStatus. atNetAddress Network Address Read-Write {atEntry 3} All GetResponse PDUs indicate a noSuchName ErrorStatus. 2.4 IP GROUP ip {mib-2 4) The TCP/IP IP Group parameters are described below.

TCP/IP MIB-II ipAddrTable Not Accessible {ip 20} A list of IP address entries; one per IP address. If a port has not yet learned its IP address, then an ipAddrEntry might not exist for the port (i.e., having an ipAddrEntry with an IP address of zero is not acceptable). ipAddrEntry Not Accessible {ipAddrTable 1} A set of objects for an ipAddrTable entry. The individual components are described below. ipAdEntAddr IP Address Read-Only {ipAddrEntry 1} The IP address itself.
TCP/IP MIB-II ipAdEntReasmMaxSize Integer Read-Only {ipAddrEntry 5} The largest IP datagram which can be reassembled, i.e., the constant 4470. 2.4.2 IP Routing Table The TCP/IP IP routing table contains the routing information for each route currently known by the ELS10-26. When adding a row, the entire row must be specified, except for the following defaults: • ipRouteDest is obtained from the row’s instance identifier. • ipRouteMetric1 defaults to 0.

TCP/IP MIB-II ipRouteInfo Object Identifier Read-Write {ipRouteEntry 13} A reference to additional MIB definitions, specific to the routing protocol which is responsible for this route. This information is not present in the ELS10-26, so ipRouteInfo should be set to the object identifier {0 0}. 2.4.3 IP Address Translation Table The TCP/IP IP address translation table contains mappings of Internet addresses to MAC addresses, except for the Internet addresses of the ELS10-26 itself.
TCP/IP MIB-II ipNetToMediaEntry Not Accessible {ipNetToMediaTable 1} A set of objects for an ipNetToMediaTable entry. The individual components are described below. ipNetToMediaIfIndex Integer Read-Write {ipNetToMediaEntry 1} The port number for which this entry is effective. ipNetToMediaPhysAddress Physical Address Read-Write {ipNetToMediaEntry 2} The MAC address (for the PPP port, this should be a zero length octet string; for Ethernet ports, this should be a little-endian six byte address).

SYNTAX INTEGER ACCESS read-only STATUS mandatory ctIfConnectionType {ctIfEntry 3} This defines the specific type of interface connection (BRIM, etc.). This is defined within ctron-oids.
TCP/IP MIB-II interface has been closed and then opened again. A read of ctIfLAA will always return the same values as IfPhysAddress, except in the case where; o ctIfLAA has been set, but interface has not yet been closed and reopened, in this case the last set value is returned. Note that a read of IfPhysAddress will always return the physical address currently being used by the interface.
TCP/IP MIB-II SYNTAX INTEGER {other (1), standard (2), fullDuplex (3), fastEthernet (4)} ACCESS read-only STATUS mandatory OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.2.1.1.6 The OID will actually be 1.3.6.1.4.1.52.4.3.3.2.1.1.6.X where X is the interface number (port number) requested. It will report fullDuplex (3) on our ethernet ports, and fastEthernet (4) on our fast ethernet ports. It will report other (1) on our UART (Local Console Management or PPP) port. 2.
TCP/IP MIB-II ctIfPortPortNumber ctIfPortPortNumber {ctIfPortEntry 1} This defines the port that is being described. SYNTAX INTEGER ACCESS read-only STATUS mandatory OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.3.1.1.1 The OID will actually be 1.3.6.1.4.1.52.4.3.3.3.1.1.1.X.Y where X is the interface number and Y is the port requested. X will increment from 1 to 28 (25 Ethernet, 2 Fast Ethernet, and the LCM port). Y will always be 1 because there is only one port per interface.
TCP/IP MIB-II ctIfPortType {ctIfPortEntry 3} DESCRIPTION This defines the specific type of port (EPIM, TPIM). This is defined within ctron-oids. SYNTAX OBJECT IDENTIFIER ACCESS read-only STATUS mandatory OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.3.1.1.3 The OID will actually be 1.3.6.1.4.1.52.4.3.3.3.1.1.1.X.Y where X is the interface number and Y is the port requested. X will increment from 1 to 28 (25 Ethernet, 2 Fast Ethernet, and the LCM port).

SYNTAX INTEGER {lm(1), ups(2), slip(3), ppp(4)} ACCESS read-write STATUS mandatory OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.4.1.1.2 The OID will actually be 1.3.6.1.4.1.52.4.3.3.4.1.1.2.1 because there is only one UART port. We support LM and PPP simultaneously. If we detect a PPP packet we do negotiations and enter into PPP mode. As long as PPP keeps live messages we’ll stay there.
TCP/IP MIB-II ctCpAdminStatus {ctCpEntry 4} DESCRIPTION The administrative state of the Com Port. SYNTAX INTEGER {disabled(1), enabled(2)} ACCESS read-only STATUS mandatory OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.4.1.1.4 The OID will actually be 1.3.6.1.4.1.52.4.3.3.4.1.1.4.1 because we only have the one UART port. We don’t allow this port to be turned on or off. Because of this, it will be READ-ONLY. It will always return enabled (2). 2.
TCP/IP MIB-II STATUS mandatory 2.16 TRAP DESCRIPTION InterfacePortInsertion Not Supported.

CHAPTER 7 TRAPS The unit sends Trap PDUs to the NMS, using the pre-configured NMS IP address (see lxadminNMSIPAddr). If no address has been pre-configured, then the unit sends the Traps to the source IP address of the last SNMP datagram received from an NMS. If no address has been pre-configured, and if no datagrams have been received since the unit was booted, then the unit uses the broadcast IP address.
Traps authenticationFailure (4) - This trap is generated whenever the community name in a PDU does not match the corresponding password. All SetRequest PDUs must match the configAnyPass (refer to the of lxadminGetPass for SetRequest exceptions), GetRequest PDUs must match either the lxadminGetPass or the configAnyPass. The GetRequest exception is for one of the debugging attributes; those PDUs must always provide the lxadminAnyPass. egpNeighborLoss (5) - Not used by the ELS10-26. 7.
