1.3.6.1.2.1.68.1.3.1.1 |
vrrpOperVrId |
Integer32{(1,255)} |
not-accessible |
This object contains the Virtual Router Identifier (VRID). |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.68.1.3.1.2 |
vrrpOperVirtualMacAddr |
OCTET STRING{(6,6)} |
read-only |
The virtual MAC address of the virtual router. Although this object can be derived from the 'vrrpOperVrId' object, it is defined so that it is easily obtainable by a management application and can be included in VRRP-related SNMP traps. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.68.1.3.1.3 |
vrrpOperState |
INTEGER{initialize(1),backup(2),master(3)} |
read-only |
The current state of the virtual router. 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. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.68.1.3.1.4 |
vrrpOperAdminState |
INTEGER{up(1),down(2)} |
read-create |
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'. |
The actually supported access is read-only. At present, this object value can only be Up. |
|
1.3.6.1.2.1.68.1.3.1.5 |
vrrpOperPriority |
Integer32{(0,255)} |
read-create |
This object specifies the priority to be used for the virtual router master election process. 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). |
The actually supported access is read-write. |
|
1.3.6.1.2.1.68.1.3.1.6 |
vrrpOperIpAddrCount |
Integer32{(0,255)} |
read-only |
The number of IP addresses that are associated with this virtual router. This number is equal to the number of rows in the vrrpAssoIpAddrTable that correspond to a given IF index/VRID pair. |
The actually supported value range is 16. |
|
1.3.6.1.2.1.68.1.3.1.7 |
vrrpOperMasterIpAddr |
IpAddress |
read-only |
The master router's real (primary) IP address. This is the IP address listed as the source in VRRP advertisement last received by this virtual router. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.68.1.3.1.8 |
vrrpOperPrimaryIpAddr |
IpAddress |
read-create |
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. |
The actually supported access is read-only. At present, this value cannot be set. By default, the primary IP address of the interface is used as the source address of VRRP Advertisement packets. |
|
1.3.6.1.2.1.68.1.3.1.9 |
vrrpOperAuthType |
INTEGER{noAuthentication(1),simpleTextPassword(2),ipAuthenticationHeader(3)} |
read-create |
Authentication type used for VRRP protocol exchanges between virtual routers. This value of this object is the same for a given ifIndex. New enumerations to this list can only be added via a new RFC on the standards track. |
The actually supported access is read-write. The authentication type is selected as required by the VRRP backup group. |
|
1.3.6.1.2.1.68.1.3.1.10 |
vrrpOperAuthKey |
OCTET STRING{(0,16)} |
read-create |
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. |
The actually supported access is read-write. |
|
1.3.6.1.2.1.68.1.3.1.11 |
vrrpOperAdvertisementInterval |
Integer32{(1,255)} |
read-create |
The time interval, in seconds, between sending advertisement messages. Only the master router sends VRRP advertisements. |
The actually supported access is read-write. |
|
1.3.6.1.2.1.68.1.3.1.12 |
vrrpOperPreemptMode |
INTEGER{true(1),false(2)} |
read-create |
Controls whether a higher priority virtual router will preempt a lower priority master. |
The actually supported access is read-write. |
|
1.3.6.1.2.1.68.1.3.1.13 |
vrrpOperVirtualRouterUpTime |
TimeTicks |
read-only |
This is the value of the `sysUpTime' object when this virtual router (i.e., the `vrrpOperState') transitioned out of `initialized'. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.68.1.3.1.14 |
vrrpOperProtocol |
INTEGER{ip(1),bridge(2),decnet(3),other(4)} |
read-create |
The particular protocol being controlled by this Virtual Router. New enumerations to this list can only be added via a new RFC on the standards track. |
The actually supported access is read-only. At present, only IP is controlled by the virtual router. |
|
1.3.6.1.2.1.68.1.3.1.15 |
vrrpOperRowStatus |
INTEGER{active(1),notInService(2),notReady(3),createAndGo(4),createAndWait(5),destroy(6)} |
read-create |
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. |
This object is implemented as defined in the corresponding MIB files. |
