CISCO-C8500-REDUNDANCY-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.

	DESCRIPTION
		"This MIB allows management of redundancy of CPU and 
                 switch cards for the Catalyst 8540 switch, and other 
                 products with similar implementations.

	         The Catalyst 8540 is an ATM switch. It has 13 (or, in
	         some models, 14) slots, of which 2 slots can hold CPU
	         cards, and 3 (or, in some models, 4) slots can hold
	         switch cards. A switch card is one that contains the
	         ATM switching fabric. Two switch cards are combined 
	         to operate in 20Gbps switching mode.
                 For CPU cards, 1+1 redundancy is supported.
                 For switch cards, 2+1 redundancy is supported."

-- Terminology

-- A "redundancy group" is a set of cards (or, in general, physical or logical 
-- entities), that may operate in a redundant manner. This
-- means that at any time one or more member entities (e.g., cards) of the
-- group are 'active', while others are 'standby', such that if an active
-- member fails, one of the standby members becomes active in its stead.
-- It is also possible for a member to be 'unused', in which case it
-- is out of service. See the definition of RedundancyMode below.

-- A "switchover" is an event in which an active card
-- either becomes a standby (because the card failed, or
-- because of user configuration) or is removed, and another
-- card that was previously standby becomes active.


-- Textual Conventions


RedundancyStatus ::= TEXTUAL-CONVENTION
	STATUS current
	DESCRIPTION
		"The operational status of a card."
	SYNTAX INTEGER {
		     notPresent(1), -- no card in slot
		     ok(2),
		     fault(3) 
	}


RedundancyMode ::= TEXTUAL-CONVENTION
        STATUS current
        DESCRIPTION
                "The redundancy mode of a card.

		The redundancy mode of a card is part of the state of
		the redundancy machine (i.e., the hardware or software
		that implements redundancy). The redundancy modes of
		all the cards in a redundancy group together represent
		the state of the redundancy machine for that
		redundancy group. The inputs to the redundancy machine
		that cause the redundancy mode of a card to transition
		from one value to another are events like card
		failure, card removal, user configuration, etc.
		Objects defined using this TC have a MAX-ACCESS of
		read-write or read-create. This allows a user to force
                the redundancy machine to transition to a desired state.
		
                The following values may be written:

                  active(1) - Make this card an active member of the
                redundancy group.

                  standby(2) - Make this card a standby member of
		the redundancy group.

                  unused(3)  - Do not use this card.

                Writing the above values may cause a switchover.

                When read, the values mean:

                 active(1) - This card is an active member of the
                redundancy group.

                 standby(2) - This card is a standby member of the
                redundancy group.

                 unused(3) - This card is not being used at present.

                 notPresent(4) - There is no card in the slot.
               "
	SYNTAX INTEGER {
		     active(1), -- also called 'primary'
		     standby(2), -- also called 'secondary'
		     unused(3), -- 'not used' or 'non participant'

RedundancySlotIndex ::= TEXTUAL-CONVENTION
	STATUS current
	DESCRIPTION
		"A value that identifies a physical slot in the chassis.

                 the leftmost slot has value 1.

                 the topmost slot has value 1."
