  • Page 9: Chapter 1 Introduction

    FN10 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 FN10. You should use this manual with the Fast Network 10 User Guide and with the documentation provided with your NMS.

  • Page 10: Document Conventions

    Chapter 1: Introduction 1.1 DOCUMENT CONVENTIONS The following conventions are used in presenting information in this manual: Note symbol. Calls the reader’s attention to any item of NOTE information that may be of special importance. Tip symbol. Conveys helpful hints concerning procedures or actions.

  • Page 11: Related Documentation

    You may need to refer to the following Cabletron documentation: • Fast Network 10 User Guide – contains installation, configuration, and management instructions for the FN10. It also describes how to use the Local Console Manager (LCM), which is a non-intelligent terminal interface to the FN10.

  • Page 12: Snmp Primitives

    The NMS must rely on IP, rather than MAC addressing for all datagrams sent to an FN10. • All datagrams from the FN10 are addressed to either an NMS or the broadcast IP address. • Within the context of this document, the terms “datagram”, “packet”, and “PDU”...

  • Page 13: Mib Primitive Types

    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.

  • Page 14: User Functions

    Change the FN10’s value of certain parameters - the NMS uses the SetRequest PDU, and the FN10 responds with a GetResponse PDU. The FN10 will change both its current value and its local default to be used when the FN10 reboots, unless noted otherwise.

  • Page 15: Navigating Through The Mibtree Structure

    Many parameters are described by existing Management Information Base (MIB) documents. The meanings of those parameters are not always implemented exactly by the FN10; instead, the parameters are treated as best as can be correlated to the FN10’s parameters. The FN10 parameters that cannot be...
  • Page 16 1.3.6.1.2.1.1. To find the amount of time the FN10 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 17 Bridge There are additional groups under MIB-II, but all groups are not supported by the FN10. 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.

  • Page 18: Tftp

    filterCurrentCount variable in the Cabletron MIB filter group and add it to the prefix 1.3.6.1.4.1.97. After the prefix, add the FN10 group ID {2}, the filter group ID {9}, and the filterCurrentCount ID of {2}. As stated above, the zero {0} indicates that this variable is a single instance and only one variable can be returned.

  • Page 19: Additional Interfaces

    FN10 will not use the incomplete new software. 1.9 ADDITIONAL INTERFACES In addition to SNMP and TFTP, the FN10 employs the following protocols, as part of its software interface with an NMS: • UDP - User Datagram Protocol, RFC 768.

  • Page 26 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 FN10 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 27: 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 FN10 returns a GetResponse with a noSuchName ErrorStatus).

The entry will be deleted (if there is no learned information) when the FN10 is told to set addrOperation to “update”, unless any of the following is true: entry-static is set, entry-no-source is set, entry-no-multi is set.
  • Page 97 NMS should read all of the dynamically learned addresses from all bridges, and use the spanning tree states of the bridges’ ports to determine the devices actual locations. To read all of a FN10’s dynamically learned addresses, the NMS must use the dot1d MIB or perform the following steps: Step 1.

  • Page 112: Filter Group

    This attribute group provides the mechanism by which the NMS may create, modify, or delete the FN10’s combination filters. A combination filter consists of many tests that are simultaneously applied to a packet, to determine if the packet should be filtered. Several combination filters may exist. Each combination filter (i.e., each set of tests) is used sequentially, and the packet is filtered if any of the...
  • Page 113 filters.] Step 5. Set the sxfilterAddID field to contain the next available filter ID. Once the FN10 receives this SetRequest, the FN10 renumbers all of the filters, thereby invalidating the NMS’s combination filters information.
  • Page 114 Integer Read-Write A filter identifier used for deleting filters. After the NMS sets this field, the FN10 deletes the sxfilterEntry that has a matching filter ID field, and resets this field to zero. The FN10 then updates sxfilterCurrentCount, sxfilterNextID, and the entire sxfilterTable.
  • Page 115 A set of flag bits which control the operation of the filter. Filters will not prevent packets from being accepted by the FN10 as a final destination (e.g., for NMS packets being used to control the FN10). The following bits are used: •...

    The total number of packets which were discarded due to this filter. Under some circumstances when packets are not forwarded (e.g., local traffic, or packets that are addressed to the FN10 itself as the final destination), sxfilterPktsCnts is not necessarily incremented when the filtering criteria agrees with the packet’s contents.
  • Page 120 Step 4. Set sxdebugOperation with the modify (2) value. All of the above “sets” must be performed in a single SetRequest PDU, with sxdebugOperation being the last parameter. This will cause the FN10 to modify the desired memory locations, update the sxdebugLength parameter, and return the updated parameter in the GetResponse PDU.
  • Page 121 A series of 0-64 octets, which represents 0-16 words (this may change in the future, if the FN10 has processors with word sizes of other than 4 bytes per word). When this variable is read, the FN10 uses the values in sxdebugBase and sxdebugLength to return the contents of a specified memory range to the NMS.

  • Page 122: Loopback Command Group

    In remote loopback, the port is in normal operation, sending/receiving normal packets. In addition, the FN10 generates loopback packets to be sent out the port to a particular destination device on the port’s network. That destination device echoes the packet back onto the network, which the port then receives.
  • Page 123 The type of loopback being performed. Setting sxlpbkOperation to loopback-off causes loop back operation to terminate. Setting sxlpbkOperation to loopback-local or loopback-remote causes loopback operation to commence, and the FN10 automatically resets sxlpbkOperation to loopback-off when the loopback operation has completed. Possible values •...
  • Page 124 Integer Read-Write The number of bytes of data to be added to the loopback packet after each successful loopback packet transmission and reception. When the port’s maximum packet size has been reached, the FN10 automatically begins again, starting with sxlpbkPktLength. sxlpbkGoods Counter Read-Only The number of packets successfully looped back.
