  • Page 11: 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.

  • Page 12: Related Documentation

    (2nd edition), Marshall T. Rose, Prentice Hall © 1994. This manual describes the software interface between the NMS and the ELS10-26. This is relevant for an ELS10-26 running Version 1.0 software. The NMS communicates with the ELS10-26 software. The Network Management, or UART, port is the interface to the Local Console Manager (LCM).

The following conventions are also used in this document: Note: Calls the reader’s attention to any item of information that may be...

  • Page 15: Snmp Primitives

    The NMS must rely on IP, rather than MAC addressing for all datagrams sent to an ELS10-26. Therefore: • All datagrams from the ELS10-26 are addressed to either an NMS or the broadcast IP address. • Within the context of this document, the terms “datagram,”...

  • Page 16: Mib Primitive Types

    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.

  • Page 18 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. • The values within the variable bindings of the returned GetResponse may reflect meaningful information, rather than...

    MIB, a group or table within that MIB, and then to the individual variable. Figure 1-1 shows the path down the MIB tree structure. Under the “mib-2” and the Cabletron enterprise branch, are all the relevant MIBs that the ELS10-26 supports.
  • Page 20 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 amount of time the ELS10-26 had been running, you would want to get the sysUpTime variable, which is the third object in the system group. So the get command would look like: get 1.3.6.1.2.1.1.3.0...

  • Page 23: 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...
  • Page 24 If the bulk retrieval of all of the parameters of the ELS10-26 had been performed while the ELS10-26 was executing that older software, that retrieved file should be used to do a bulk set of all parameters (as described below).

  • Page 25: Retrieving All Parameters

    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”).

  • Page 26: Additional Interfaces

    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.

  • Page 27: 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...

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 The number of non-multicast packets received by the port, regardless of the packet’s outcome (i.e., whether the packet was...
  • Page 33 The number of packets to be transmitted out the port, but were not transmitted due to non-error reasons. The definition of non-error reasons is implementation dependent. The ELS10-26 defines non-error reasons as packet congestion. Packet congestion occurs when too many packets are to be queued for transmission, or when packets have been awaiting transmission for too long a time period.

  • Page 34: Address Translation Group

    2.3 ADDRESS TRANSLATION GROUP The TCP/IP Address Translation Group parameters are minimally supported (i.e., for any parameter in this group, the ELS10-26 returns a GetResponse with a noSuchName ErrorStatus). It is anticipated that the Address Translation Group will be deleted...

    The TCP/IP IP Group parameters are described below. ipForwarding Integer Read-Write Whether the ELS10-26 is an IP router. This value is always host (2).

  • Page 39 The network/subnet mask associated with the IP address. For SetRequests, a mask of zero may be specified, in which case, the ELS10-26 will create the correct network mask for a non-subnetted network. For GetRequests, the ELS10-26 will always convert a value of zero into the correct network mask.

  • Page 40: Ip Routing Table

    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.
