It should be deleted when the document is published -- as an RFC. -- -- * Aug/Sept/Oct 1999: Changes in 9th rev. (draft-ietf-vrrp-mib-09.txt): -- -- - Changed description for "vrrpTrapNewMaster" object. -- - Removed the "ifIndex" and "vrrpOperVrId" objects from the -- "vrrpTrapNewMaster" trap. This is because these objects are -- already present in the trap in the form of table indices. -- The "vrrpOperMasterIpAddr" object has replaced these in the -- trap. -- - As above, removed the "ifIndex" and "vrrpOperVrId" objects -- from the "vrrpTrapAuthFailure" trap. -- - Changed the DESCRIPTION clause of the MODULE-IDENTITY statement. -- - Added REVISION and secondary DESCRIPTION clauses to MODULE- -- IDENTITY macro. -- - Removed REFERENCE and DEFVAL clauses from the definition of -- the "vrrpNodeVersion" object. -- - Added IMPORT for NOTIFICATION-GROUP. -- - Since last sub ID of trap must be 0 (RFC2578), "vrrp- -- Notifications" has been redefined as {vrrpMIB 0} and traps -- defined directly under it. As per this change, the "vrrpTraps" -- object has been eliminated. Definition of the vrrpNotifications -- object was also moved to the "Trap Definitions" section of the -- MIB. -- - Both the "vrrpOperVrId" and "vrrpOperAssoIpAddr" were removed -- from the "vrrpOperGroup" definition. Since these are both -- not-accessible objects, this eliminates MIB compiler warnings. -- - Added new "vrrpNotificationGroup" NOTIFICATION-GROUP which -- contains the VRRP MIB traps. -- - Added WRITE-SYNTAX for "vrrpOperPriority" in Conformance -- section. This excludes setting of '0'. -- - Added UNITS clause to "vrrpOperAdvertisementInterval" -- - Changed (or removed) "SNMPv2" references to "SMIv2". -- - In section 2.1, changed bullet item from "traps" to -- "notifications". -- - In section 2.2, changed "IF Index" to ifIndex". -- - Changed label in MODULE-IDENTITY from "vrrp" to "vrrpMIB". -- - Added required Intellectual Property Statement (Section 8) -- and a Full Copyright Statement (Section 9). -- - Renamed "vrrpTrapsCntl" to "vrrpNotificationCntl" for -- consistancy with recent RFC's. -- - ------- -- - Removed redundant "vrrpMIB" definition (after MODULE-IDENTITY -- statement) that was causing compile errors. -- - Removed "{}" from WRITE-SYNTAX of "vrrpMIBCompliance", as this -- was causing compile errors. -- - Added " vrrpTrapGroup" definition to contain objects used -- exclusively in VRRP traps. This eliminates compiler warnings. -- - Reference #18 (RFC1213 - IF MIB) was removed, as RFC 2233 -- has obsoleted it. -- - Reference #22 ("Instructions to RFC Authors") was removed. -- - Rewrote to DESCRIPTION for "vrrpOperRowStatus" to eliminate -- redundant wording that can be found in the RowStatus TC -- (RFC2579). -- - Added text to the DESCRIPTION of the "vrrpOperAdminState" -- explaining how it is decided whether to transition a VR to -- "backup" or "master". -- - ------- -- - Removed references [18], [19], [20] (RFC1902, RFC 1903, -- RFC 1904, respectively), as these have been obsoleted by -- newer documents. Reference [21] was renumbered to [18], -- accordingly. -- - Changed reference from [18] to [5], as per aforementioned -- change. -- - Changed reference to "MIB-II" to "IF-MIB". -- - Moved the OIDs for the "vrrpTrapPacketSrc" and -- "vrrpTrapAuthErrorType" objects under the "vrrpOperations" -- (vrrp 1) branch. This is to distinguish the OIDs of these -- objects from the "vrrpNotifications" OIDs. As part of -- this change, the OIDs for the two VRRP notifications -- were decremented accordingly. -- - Added disclaimer to Overview section regarding that IP -- addresses in this MIB are IPv4 specific and will not be -- compatible in an IPv6 environment. -- -- -- * June 1999: Changes in 8th revision (draft-ietf-vrrp-mib-08.txt): -- -- - Changed inport of "ifIndex" from RFC 1213 to IF-MIB. -- - Added new IANA assigned MIB OID (68). -- -- -- * June 1999: Changes in 7th revision (draft-ietf-vrrp-mib-07.txt): -- -- - Added MIB Boilerplate for "The SNMP Management Framework" section. -- - Added "Security Considerations" section -- - Removed references to "SNMPv2" in header and footers. -- -- -- * May, 1999: Changes in 6th revision (draft-ietf-vrrp-mib-06.txt): -- -- - Removed description of how "vrrpOperVirtualMacAddr" is specifed -- as per changes to the VRRP Spec (addition of Token Ring). -- - Added citiations for RFC 1903 and RFC 1904 in references. -- - Modifed reference to RFC 1573, which has been obsoleted by RFC -- 2233. -- -- -- * March, 1999: Changes in 5th revision (draft-ietf-vrrp-mib-05.txt): -- -- - Objects under "vrrpRouterStatsEntry" were renumbered. OID's -- became out-of-sequence due to changes made in the last revision -- (04). -- - Format of section numbers was changed ('.' added) to be consistant -- with other RFC's. -- - Changed the type of "vrrpNodeVersion" from INTEGER to Integer32. -- Also made DEFVAL (for this object) a decimal number. -- - A few spelling and typographical corrections were made. -- - Revisions were made to the format of some of the references to -- make then more concise and consistant. -- - Reworded the Overview section to attempt to make the description -- of VRRP more in-line with the VRRP RFC. -- -- -- * January, 1999: Changes in 4th revision (draft-ietf-vrrp-mib-04.txt): -- -- - "vrrpNodeVersion" SYNTAX changed from OCTET STRING to INTEGER. -- - Removed the REFERENCE clause from "vrrpOperVirtualMacAddr", as it -- was deemed redundant. -- - The range of vrrpOperAddrCount was changed from (1..255) to -- (0..255). This reflects the fact that a row might be created -- in the vrrpOperTable *prior* to creating a row in the -- vrrpAssoIpAddrTable. -- - Removed DEFVAL clause from "vrrpOperAuthKey" as unnecessary. -- - Moved the following objects out of the "vrrpRouterStatsTable" -- to become "global" VRRP router objects: "vrrpStatsChecksunErrors", -- "vrrpStatsVersionErrors", "vrrpStatsVrIdErrors". Each of these -- was renamed "vrrpRouter*", accordingly (since they are no longer -- members of the vrrpRouterStatsTable. The reason for this change -- is that, when any of these events occur, attempting to map the -- packet, with possible corruption of the VRID (or other fields), -- into a row of the vrrpRouterStatsTable would be risky, at best. -- - Removed "vrrpOperVirtualMacAddr" from the "vrrpTrapNewMaster". -- Since the virtual MAC can be derived from the VR ID, this was -- extra payload in the trap. -- - removed "vrrpTrapConfigErrorType" and "vrrpTrapPacketSrc" -- from conformance groups, as these are not mandatory objects. -- - Added new object, "vrrpOperPrimaryIpAddr" to vrrpOperTable. -- This object allows for designation of the vrrp IP primary -- address on an interface with multiple IP addresses, should this -- virtual router transition from backup to master. -- - Changed vrrpRouterStatsEntry to AUGMENT the vrrpOperEntry, since -- there is a one-to-one correspondence between these two objects -- and they are indexed with identical parmeters. -- - Addded new object, vrrpStatsPacketLengthErrors, to the statistics -- table. -- - Changed the description for "vrrpStatsSecurityViolations" to apply -- to *all* types of authentication failures, as opposed to -- cleartext auth failures only, which it previously stated. -- - Renamed "vrrpTrapConfigErrorType" object to "vrrpTrapAuthErrorType" -- and added a new enumeration for "authentication failures". -- - Renamed "vrrpStatsAuthTypeErrors" to "vrrpStatsAuthTypeMismatch". -- - Renamed "vrrpStatsSecurityViolations" to " vrrpStats- -- AuthenticationFailures" -- -- -- * November, 1998: Changes in 3rd revision (draft-ietf-vrrp-mib-03.txt): -- -- - Changed name of "vrrpAssoIpAddrStatus" object to -- "vrrpAssoIpAddrRowStatus" for consistancy with similar object -- in vrrpOperTable. -- - Changed name of "vrrpOperControl" object to "vrrpOperAdminState" -- and enhanced description clause. -- - Renumbered the objects in both the vrrpOperTable and -- vrrpAssoIpAddrTable. The first objects in the tables started -- with an OID of '2', when they should have started with '1'. -- - Changed the name of "vrrpStatsUnknownAuthType" to -- "vrrpStatsInvalidAuthType" as per suggestion that it was -- more concise. -- - Rewrote the descriptions for the table Entry objects and the -- rowstatus objects to make the process of row creation and -- deletion more clear. Each enumeration of the rowstatus -- object in the "vrrpOperTable" is now clearly explained. -- - Changed MAX-ACCESS to "read-create" on the "vrrpOperAuthType" -- and "vrrpOperAuthKey" objects. This was done with the -- assumption the the VRRP RFC will change to make these -- attributes defined on a "per-virtual-router-basis" as -- was proposed at the August (1998) IETF Meeting. -- -- -- * July, 1998: Changes in 2nd revision (draft-ietf-vrrp-mib-02.txt): -- -- - A number of changes were made to the textual content of the -- draft as per feedback received at the last WG meeting. These -- changes were too numerous to document individually in this -- section. -- - The size of the "vrrpNodeVersion" object has been changed from -- 2 octets to 1 octet. -- - References to obsoleted RFC's have been replaced by references -- to later documents. Notably, references to RFC's 1442, 1443 and -- 1444 have been replaced by RFC 1902, RFC 1903 and RFC 1904, -- respectively. -- - The description for the "vrrpOperControl" was changed to -- reflect the fact that a virtual router does not necessarily -- transition directly from initialize state -> backup state. -- The description for the "vrrpStatsBecomeMaster" was also -- changed to more accurately convey this fact. -- - The SYNTAX of the "vrrpOperIpAddrCount" was changed to -- reflect the fact that a virtual router can support only up -- to 255 backup IP addresses. -- - Descriptions for vrrpOperAuthType and vrrpOperAuthKey expanded -- to indicate the per-interface assignment. -- - SYNTAX of vrrpOperPreemptMode object changed from INTEGER -- to 'truthValue' -- - The OIDs for the VRRP traps were fixed; incorrect ident- -- ifiers ('vrrpOperations') had been used in OID assignments. -- - The SYNTAX for the 'vrrpOperPriority' object was corrected -- to indicate that this can have a value of '0'. -- - The vrrpOperHMACMD5Key object was deleted. It was combined -- with the vrrpOperAuthKey object, whose SYNTAX was adjusted -- accordingly. -- - OID for 'vrrpTraps' changed to '{ vrrpNotifications 1 }' -- - The 'vrrpStatsPasswdSecurityViolations' and 'vrrpStatsHmac- -- SecurityViolations' objects have been combined into a -- single 'vrrpStatsSecurityViolations' object; this was -- suggested to avoid redundancy. -- - As per the last WG meeting, the 'vrrpAssoIpAddrIndex' object -- has been deleted from the 'vrrpAssoIpAddrTable'and replaced -- by 'vrrpAssoIpAddr'. -- - Removed references to 'vrrpAssoIpAddrIndex' in samples. -- - Added new object 'vrrpOperProtocol' to 'VrrpOperEntry'. -- - MAX-ACCESS for the 'vrrpOperVrId' object changed to -- 'not-accessible', as per RFC1902 (auxilary objects). -- - SYNTAX for 'vrrpOperVirtualRouterUpTime' changed to -- 'TimeStamp'. -- - Added importation of 'TruthValue'and 'TimeStamp' to accomodate -- changes listed above. Deleted importation of 'TimeTicks'. -- - Changed MAX-ACCESS to 'accessible-for-notify' for -- 'vrrpTrapPacketSrc' and 'vrrpTrapConfigErrorType' objects. -- - In the sample tables, the "if" values were incorrect for -- the sample tables for "IP B" (they used to read "I1"). -- - MAX-ACCESS for 'vrrpOperAuthType' and 'vrrpOperAuthKey' -- changed to 'read-only', since these objects are defined on -- a per-interface basis. -- - Overall review and editing of Section 5.0 (References) with -- deletion of references not used in this document. Also, added -- reference '9'. -- -- Concerns: -- --------- -- - Keep the 'vrrpTrapAuthFailure' trap? -- - Remove 'vrrpTrapPacketSrc' and 'vrrpTrapConfigErrorType' from -- compliances? Only used for 'vrrpTrapAuthFailure' trap. -- -- -- * 3/4/1998: Changes in 1st revision (draft-ietf-vrrp-mib-01.txt): -- -- - Overall review and editing of document text and object -- descriptions from feedback received at December 1997 IETF meeting. -- More specifically the changes made along these lines include -- the following: -- -- -- Cleaned up Section 5.0 ("References") and validated. -- -- Modifed diagram for VRRP Scenario #2 (Section 2.4.2). -- -- VRRP Overview (Section 2.0) rewritten to be more in-line with -- latest revision (05) of VRRP RFC Draft. -- -- Description of "VrId" Textual convention rewritten. -- -- - MAX-ACCESS of vrrpTrapCntl object changed to "read-write". -- - Changed SYNTAX of "vrrpOperVirtualMacAddr" object from -- "PhyAddress" to "MacAddress". -- - Changed the syntax of the "vrrpOperPriority" object so upper -- value can be 255. -- - Change MAX-ACCESS for "vrrpOperAuthType" object from -- read-only to read-create. -- - Added three new objects to "vrrpRouterStatsTable": -- "vrrpStatsAddressListErrors", "vrrpStatsUnknownAuthType" -- and "vrrpStatsAuthTypeErrors". -- - Removed "vrrpStatsUnknownPacketType" object, as it was -- redundant (with "vrrpStatsInvalidPacketType"). -- - Removed the "vrrpOperIfIndex" object to use "ifIndex" (which is -- actually equivalent) instead. -- -- -- * 11/19/97 (vft-ietf-vrrp-mib-00.txt) - Initial Draft
