CISCO-MEMORY-POOL-MIB by vendor Cisco

CISCO-MEMORY-POOL-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

    STATUS        current
    DESCRIPTION
        "Represents the different types of memory pools that
        may be present in a managed device.  Memory pools can
        be roughly categorized into two groups, predefined
        pools and dynamic pools.  The following pool types
        are currently predefined:
            1:  processor memory
            2:  i/o memory
            3:  pci memory
            4:  fast memory
            5:  multibus memory

        Dynamic pools will have a pool type value greater than
        any of the predefined types listed above.

        Note that only the processor pool is required to be
        supported by all devices.  Support for other pool types
        is dependent on the device being managed."
