CISCO-BUS-MIB device MIB details by Cisco

CISCO-BUS-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.

	MAX-ACCESS read-create
	STATUS     current
	DESCRIPTION
		" The specified ATM address of the BUS on the interface
		of interest.  Note  that setting this object will have
		the side effect   of   reinitializing  the  BUS    and
		consequently dropping all clients connected to it.  If
		this object is not specified at row creation time then
		the BUS will choose a value  for itself and attempt to

	DESCRIPTION
		"   An    address mask  that     when  used  with  the
		busAtmAddrSpec, specifies  the portion of the BUS' ATM
		address  that is desired  to be  configured. Note that
		setting    this     object   will   result   in    the
		reinitialization of the BUS, consequently dropping all
		clients connected to  it.   At row creation  time this
		object  cannot be set  without also  supplying a value
		for  the busAtmAddrSpec.  If   the BUS ATM  address is
		omitted at creation time then this object defaults to
		the  value of all  zeros  (none of the  busAtmAddrSpec
		value   is  relevant).  If the    BUS  ATM address  is
		specified  at creation time   but this object omitted,
		then this object  defaults  to the  value of all  ones
		(all of the busAtmAddrSpec is relevant)."

                The value specified for this object must equate to a
                value of ifIndex in the ifTable.  The interface  will
                be for that particular ATM port (the physical
                interface, not a logical layer on top of it). This
                object can only be specified upon row creation and
                cannot be altered there after."

		a LEC or BUS of the same ELAN  but is not required to
		do  so.  If no value  is  specified for this object at
