VRRP-MIB device MIB details by RFC
VRRP-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.

On a VRRP router, a given virtual router is identified by a combination of the IF index and VRID. Rows in the table cannot be modified unless the value of `vrrpOperAdminState' is `disabled' and the `vrrpOperState' has transitioned to `initialize'."

This object has three defined values: - `initialize', which indicates that all the virtual router is waiting for a startup event. - `backup', which indicates the virtual router is monitoring the availability of the master router. - `master', which indicates that the virtual router is forwarding packets for IP addresses that are associated with this router. Setting the `vrrpOperAdminState' object (below) initiates transitions in the value of this object." ::= { vrrpOperEntry 3 } vrrpOperAdminState OBJECT-TYPE SYNTAX INTEGER { up(1), down(2) } MAX-ACCESS read-create STATUS current DESCRIPTION "This object will enable/disable the virtual router function. Setting the value to `up', will transition the state of the virtual router from `initialize' to `backup' or `master', depending on the value of `vrrpOperPriority'. Setting the value to `down', will transition the router from `master' or `backup' to `initialize'. State transitions may not be immediate; they sometimes depend on other factors, such as the interface (IF) state. The `vrrpOperAdminState' object must be set to `down' prior to modifying the other read-create objects in the conceptual row. The value of the `vrrpOperRowStatus' object (below) must be `active', signifying that the conceptual row is valid (i.e., the objects are correctly set), in order for this object to be set to `up'."

Higher values imply higher priority. A priority of '0', although not settable, is sent by the master router to indicate that this router has ceased to participate in VRRP and a backup virtual router should transition to become a new master. A priority of 255 is used for the router that owns the associated IP address(es)."

This is the IP address listed as the source in VRRP advertisement last received by this virtual router." ::= { vrrpOperEntry 7 } vrrpOperPrimaryIpAddr OBJECT-TYPE SYNTAX IpAddress MAX-ACCESS read-create STATUS current DESCRIPTION "In the case where there is more than one IP address for a given `ifIndex', this object is used to specify the IP address that will become the `vrrpOperMasterIpAddr', should the virtual router transition from backup to master. If this object is set to 0.0.0.0, the IP address which is numerically lowest will be selected."

DEFVAL { noAuthentication } ::= { vrrpOperEntry 9 } vrrpOperAuthKey OBJECT-TYPE SYNTAX OCTET STRING (SIZE (0..16)) MAX-ACCESS read-create STATUS current DESCRIPTION "The Authentication Key. This object is set according to the value of the 'vrrpOperAuthType' object ('simpleTextPassword' or 'ipAuthenticationHeader'). If the length of the value is less than 16 octets, the agent will left adjust and zero fill to 16 octets. The value of this object is the same for a given ifIndex. When read, vrrpOperAuthKey always returns an Octet String of length zero." ::= { vrrpOperEntry 10 } vrrpOperAdvertisementInterval OBJECT-TYPE SYNTAX Integer32 (1..255) UNITS "seconds" MAX-ACCESS read-create STATUS current DESCRIPTION "The time interval, in seconds, between sending advertisement messages.

New enumerations to this list can only be added via a new RFC on the standards track." DEFVAL { ip } ::= { vrrpOperEntry 14 } vrrpOperRowStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The row status variable, used in accordance to installation and removal conventions for conceptual rows. The rowstatus of a currently active row in the vrrpOperTable is constrained by the operational state of the corresponding virtual router. When `vrrpOperRowStatus' is set to active(1), no other objects in the conceptual row, with the exception of `vrrpOperAdminState', can be modified. Prior to setting the `vrrpOperRowStatus' object from `active' to a different value, the `vrrpOperAdminState' object must be set to `down' and the `vrrpOperState' object be transitioned to `initialize'. To create a row in this table, a manager sets this object to either createAndGo(4) or createAndWait(5). Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the `vrrpOperRowStatus' column will be read as notReady(3). In particular, a newly created row cannot be made active(1) until (minimally) the corresponding instance of `vrrpOperVrId' has been set and there is at least one active row in the `vrrpAssoIpAddrTable' defining an associated IP address for the virtual router." ::= { vrrpOperEntry 15 } -- ******************************************************************* -- VRRP Associated IP Address Table -- ******************************************************************* vrrpAssoIpAddrTable OBJECT-TYPE SYNTAX SEQUENCE OF VrrpAssoIpAddrEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The table of addresses associated with this virtual router." ::= { vrrpOperations 4 } vrrpAssoIpAddrEntry OBJECT-TYPE SYNTAX VrrpAssoIpAddrEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry in the table contains an IP address that is associated with a virtual router.

Setting this object to active(1) or createAndGo(4) results in the addition of an associated address for a virtual router. Destroying the entry or setting it to notInService(2) removes the associated address from the virtual router.
