OBJECT-TYPE

The unique identifier required by SASP for all load balancers. In a redundant system, where there is a master and backup load balancer, each load balancer must have different identifiers. The slbSaspIdentifier may only be changed when the slbSaspEnabled object is false. The default value of the slbSaspIdentfier is 'Cisco-<LB>', where <LB> is the Cisco acronoym for the load balancer.

OBJECT-TYPE

Indicates whether the SASP functionality is currently in use by the load balancer. 'true' The SASP functionality is enabled on the load balancer. 'false' The SASP functionality is disabled on the load balancer.

OBJECT-TYPE

The health value reported to the SASP Agents via the Set Load Balancer State Message. The value represents the load balancer's ability to handle SASP messages.

OBJECT-TYPE

The Load Balancer's state in a redundant setup. The Load Balancer may still contact the SASP Agents, which are defined in the slbSaspAgentTable, regardless of the state. This is possible because every Load Balancer contacting a SASP Agent is required to have it's own unique identifier. Therefore, the master and backup Load Balancer MUST have different unique identifiers.

OBJECT-TYPE

The maximum number of SASP Agents that can be configured on the Load Balancer. The SASP Agents are configured via the slbSaspAgentTable.

OBJECT-TYPE

The maximum weight supported by the Load Balancer. Any weight reported for a SASP Member, which can be found within the slbSaspMemberSaspWeight object, MUST be converted to the Load Balancer's weight range. The minimum weight for a Load Balancer MUST be zero. A weight of zero indicates that the SASP Member is down and that the Member is not going to receive new connections.

OBJECT-IDENTITY

OBJECT-TYPE

A table containing information about the SASP Agents. Rows can be created and destroyed. Columnar objects can be modified when the row is 'active'. Entries are added to this table via slbSaspAgentRowStatus. A SASP Agent is an application or device that is responsible for aggregating information regarding the performance of a SASP Member. The information is used to calculate a weight that is reported to the load balancer.

OBJECT-TYPE

The SASP Agent entry provides information for a particular SASP Agent on a local SLB entity. The objects provide the contact information and the current connection state of the Agent.

OBJECT-TYPE

Defines the IP address type used by the slbSaspAgentIpAddress.

OBJECT-TYPE

The IP address of the SASP Agent that is used for weight reporting.

OBJECT-TYPE

The TCP Port number used when connecting to a SASP Agent.

OBJECT-TYPE

A label that can be assigned by the user for the SASP Agent during entry creation. The label should be in a human readable form that describes the SASP Agent. The description could be the physical location of the Agent or some other field relevant to the user. The label is provided for informational purposes only, and it does not affect the operation of the SASP Agent.

OBJECT-TYPE

The current connection state of the SASP Agent. The load balancer does not give up trying to reach the SASP Agent when it is down.

OBJECT-TYPE

Displays the date and time of the last state change that was incurred by the Agent. The time that is reported is only local time, so the timezone portion of the DateAndTime TC will not be specified.

OBJECT-TYPE

The row status is used by a management station to create or delete the row entry in slbSaspAgentTable following the RowStatus textual convention.

OBJECT-IDENTITY

OBJECT-TYPE

A table containing information about the SASP Groups. Rows can be created and destroyed. Entries are added to this table via slbSaspGroupRowStatus. A SASP Group is a logical entity used within the SASP implementation to group SASP Members that are equivalent in function.

OBJECT-TYPE

The SASP Group table provides the information for a particular group associated with a SASP Agent on a local SLB entity.

OBJECT-TYPE

The SASP group represents the group of SASP Members that have the same functional capabilities.

OBJECT-TYPE

The row status is used by a management station to create or delete the row entry in slbSaspGroupTable following the RowStatus textual convention. Removing the group from this table would have the effect of removing all of the SASP Members associated with this group from the SASP Member table.

OBJECT-IDENTITY

OBJECT-TYPE

A table containing information about the SASP Members. Rows can be created and destroyed. Columnar objects can be modified when the row is 'active'. Entries are added to this table via slbSaspMemberRowStatus. A SASP Member is an entity configured on the load balancer to help distribute the load for one or more services.

OBJECT-TYPE

The SASP Member table provides information about a particular SASP Member associated with a SASP Agent. Each entry contains all of the weight information that is necessary to use SASP on the load balancer. It is important that the SASP Member only report to one SASP Agent. This will avoid any weight reporting issues that may arise when the SASP Agent communicates with the load balancer.

OBJECT-TYPE

Defines the IP address type of the slbSaspMemberIpAddress.

OBJECT-TYPE

The IP address of the member. The IP address, along with the port and protocol type, is registered with the SASP Agent. The SASP Agent includes this information when reporting the weights for each member in either the 'Get Weights Reply' or the 'Send Weights Message'.

OBJECT-TYPE

The TCP or UDP port number associated with the slbSaspMemberIpAddress. The port number, along with the IP address and protocol type, is registered with the SASP Agent. The SASP Agent includes this information when reporting the weights for each member in either the 'Get Weights Reply' or the 'Send Weights Message'.

OBJECT-TYPE

The IP protocol type that is associated with the slbSaspMemberIpAddress and slbSaspMemberPort. The protocol type, along with the IP address and port number, is registered with the SASP Agent. The SASP Agent includes this information when reporting the weights for each member in either the 'Get Weights Reply' or the 'Send Weights Message'.

OBJECT-TYPE

The reported weight by the SASP Agent. The weights are reported via the 'Send Weights Message' or in the 'Get Weights Reply'. The reported weight MUST be converted to be within the Load Balancer's supported weight range, specified by the slbSaspMaxLbWeight object. The resulting weight value will be stored in the slbSaspMemberConvertedWeight object.

OBJECT-TYPE

Represents the SASP Agent's confidence in the reported weight. 'true' Indicates the slbSaspMemberSaspWeight value is accurate and reflects the up-to-date real-time statistics collected by the SASP Agent. 'false' Indicates the SASP Agent is guessing the weight of the member based on prior knowledge. It is at the load balancer's discretion whether or not to use this weight. If not, the default weight must be used (slbSaspMemberDefaultWeight).

OBJECT-TYPE

The SASP weight converted to the local load balancer weight range. The load balancer's weight range is implementation dependent, as is the formula used to convert the weight. The following formula is an example weight conversion that could be used by the load balancer: answer => slbSaspMemberConvertedWeight maxLbWgt => slbSaspMaxLbWeight mbrSaspWgt => slbSaspMemberSaspWeight answer = ((mbrSaspWgt * maxLbWgt) / 65535) + 1 Note: There are two edge cases that need to be considered; when the mbrSaspWgt is 0 and 65535. If the mbrSaspWgt is 0, then the converted weight must also be 0 (the result of the calculation would be 1). If the mbrSaspWgt is 65535, then the converted weight must be the load balancers maximum weight (the result of the calculation would be the load balancers maxiumum weight plus 1).

OBJECT-TYPE

The default weight assigned to the member if any SASP Agent weight reporting failure occurs. If there is a communication failure or if the slbSaspMemberConfidentWeight is false, then the load balancer should use this weight as its fallback weight when making load balancing decisions.

OBJECT-TYPE

The total number of times the weight has been modified by the SASP Agent.

OBJECT-TYPE

Displays the date and time of the last weight change. The time that is reported is only local time, so the timezone portion of the DateAndTime TC will not be specified. If there have been no reports, the empty string is returned.

OBJECT-TYPE

The row status is used by a management station to create or delete the row entry in slbSaspMemberTable following the RowStatus textual convention.

OBJECT-IDENTITY

OBJECT-TYPE

A table containing information about the Server Application State Protocol Statistics. Rows are created and destroyed when an entry for the slbSaspAgentTable is created or destroy via the slbSaspAgentRowStatus.

OBJECT-TYPE

Each entry corresponds to a SASP Agent from the slbSaspAgentTable. Each entry contains statistics related to the transmitted and received SASP messages. A slbSaspStatsTableEntry cannot exist without a corresponding entry in the slbSaspAgentTable.

OBJECT-TYPE

The total number of SASP Registration Requests transmitted from the load balancer to the SASP Agent. The registration message informs the Agent to start reporting the server weight for each member listed in the message.

OBJECT-TYPE

The total number of SASP Deregistration Requests transmitted from the load balancer to the SASP Agent. The deregistration message informs the Agent to stop reporting the server weight for each member listed in the message.

OBJECT-TYPE

The total number of SASP Get Weight Requests transmitted from the load balancer to the SASP Agent. The get weights message is only used when the load balancer is actively retrieving the weight for each member.
