1-1 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 ne...

1-2 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-intellig...

1-4 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...

1-6 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 On...

Introduction 1-7 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...

1-8 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 ...

Introduction 1-9 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 Stand...

1-10 Introduction Figure 1-1 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. To find the a...

Introduction 1-11 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 associ...

1-12 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 ...

Introduction 1-13 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 spe...

1-14 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 priva...

Introduction 1-15 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 TFT...

1-16 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. • ...
