CISCO-IMAGE-CHECK-MIB device MIB details by Cisco

CISCO-IMAGE-CHECK-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.

--
--   When a switch runs different versions of software on the active
--   and the standby supervisor, the behaviour of the two versions
--   of the software can be different. 
--   The objective of this MIB is to perform a HA compatibility check
--   of the two versions of the software and list the incompatibilities
--
--   To achieve this goal, there are 2 tables defined in this MIB.
--
--   ciscoImageCheckOpTable, is an 'operations' table, in that this
--   table is used to invoke a command to perform a check on the 
--   images.
--
--   ciscoImgChkResultsTable, is a read-only table where the results of
--   previous operation are read. It is this table that lists the
--   incompatibilities.
--  
--   Terminology -
--
--     HA         - High Availability
-- 
--     Feature    - A software service like zoning, routing etc.
--
--     Capability - A configuration attribute mapping to some
--                  hardware-dependent configuration. A 
--                  capability is described by this infrastructure if
--                  it can be programmed in one version of the software
--                  but it can't be programmed in some earlier version.
--
--     Strict and Loose incompatibility - An incompatibility exists 
--                  between the configuration of the software running
--                  on the active supervisor and the configuration 
--                  supported by the standby supervisor when a specific
--                  capability is enabled, but software on the standby
--                  supervisor does not support it. The incompatibility
--                  is said to be 'Strict', when a switchover to the 
--                  older version software release would cause some
--                  unpredictable behaviour as long as the capability 
--                  is enabled. The incompatibility is said to be
--                  'Loose' when a switchover to the older release
--                  would not cause an unpredictable behaviour or 
--                  instability in the system.

	DESCRIPTION
		"An Image check operation entry. Each entry consists 
		of an image name, current status of the check
                operation and a row status.

		A management station wishing to create an entry should
		first generate a pseudo-random serial number to be used
		as the index to this sparse table.  The station should
		then create the associated instance of the row status
		object. It must also, create the associated instance
		of the image name. This image is checked for 
                compatibility with the image already running on the
                active supervisor.

		Once the appropriate instances of all the mandatory
		objects have been created, either by an explicit SNMP
		set request or by default, the row status should be set
		to active to initiate the operation. Note that this entire
		procedure may be initiated via a single set request which
		specifies a row status	of createAndGo.

		Once an operation has been activated, it cannot be
		stopped. 

		Once the operation completes, the management station should
		retrieve the value of the status object and delete the
		entry.  In order to prevent old entries from clogging the
		table, entries will be aged out, but an entry will never
		be deleted within 5 minutes of completing.
