SNMP/RMON MIBs Support

Introduction

Management and counter information are stored in the switch in the Management Information Base (MIB). The switch uses the standard MIB-II Management Information Base module. Values for MIB objects can be retrieved from any SNMP-based network management software.

In addition to the standard MIB-II, the switch also supports its own proprietary enterprise MIB as an extended Management Information Base. The proprietary MIB is retrieved by specifying the MIB Object-Identifier (OID) at the network manager station.

MIB values can be either read-only or read/write variables.

Read-only MIB variables can be constants that are programmed into the switch or variables that change while the switch is in operation. Examples of read-only constants include the number and types of ports. Examples of read-only variables are the statistics counters, such as the number of errors that have occurred or how many kilobytes of data have been received and forwarded through a port.

Read/write MIB variables are usually related to user-customized configurations. Examples include the IP address of the switch, Spanning Tree Algorithm parameters, and port status.

SNMP Manager Software

If you use third-party vendor SNMP software to manage the switch, a diskette listing the propriety enterprise MIBs for the switch can be obtained by request. If your software provides functions to browse or modify MIBs, you can also change the MIB values (if the MIB attributes permit the write operation). This process can be quite involved, however, because you must know the MIB OIDs and retrieve them one by one.

Use an SNMP manager, such as HP OpenView or Tivoli NetView, to access the enterprise- specific MIBs. Compile the MIBs into the MIB database and then use a MIB browser to navigate through them. For detailed information, access the individual descriptions of each MIB or go to the documentation that came with your SNMP manager software.
