sFlowMIB 1.3.6.1.4.1.4300.1
The MIB module for managing the generation and transportation of sFlow data records.

sFlowVersion 1.3.6.1.4.1.4300.1.1.1
Uniquely identifies the version and implementation of this MIB. The version string must have the following structure: ;; where: must be '1.2', the version of this MIB. the name of the organization responsible for the agent implementation. the specific software build of this agent. As an example, the string '1.2;InMon Corp.;2.1.1' indicates that this agent implements version '1.2' of the SFLOW MIB, that it was developed by 'InMon Corp.' and that the software build is '2.1.1'. The MIB Version will change with each revision of the SFLOW MIB. Management entities must check the MIB Version and not attempt to manage agents with MIB Versions greater than that for which they were designed. Note: The sFlow Datagram Format has an independent version number which may change independently from . applies to the structure and semantics of the SFLOW MIB only.

sFlowAgentAddressType 1.3.6.1.4.1.4300.1.1.2
The address type of the address associated with this agent. Only ipv4 and ipv6 types are supported.

  InetAddressType  

sFlowAgentAddress 1.3.6.1.4.1.4300.1.1.3
The IP address associated with this agent. In the case of a multi-homed agent, this should be the loopback address of the agent. The sFlowAgent address must provide SNMP connectivity to the agent. The address should be an invariant that does not change as interfaces are reconfigured, enabled, disabled, added or removed. A manager should be able to use the sFlowAgentAddress as a unique key that will identify this agent over extended periods of time so that a history can be maintained.

sFlowDataSource 1.3.6.1.4.1.4300.1.1.4.1.1
Identifies the source of the data for the sFlow sampler. The following data source types are currently defined: - ifIndex. DataSources of this traditional form are called 'port-based'. Ideally the sampling entity will perform sampling on all flows originating from or destined to the specified interface. However, if the switch architecture only permits input or output sampling then the sampling agent is permitted to only sample input flows input or output flows. Each packet must only be considered once for sampling, irrespective of the number of ports it will be forwarded to. Note: Port 0 is used to indicate that all ports on the device are represented by a single data source. - sFlowPacketSamplingRate applies to all ports on the device capable of packet sampling. - sFlowCounterSamplingInterval applies to all ports. - smonVlanDataSource. A dataSource of this form refers to a 'Packet-based VLAN' and is called a 'VLAN-based' dataSource. is the VLAN ID as defined by the IEEE 802.1Q standard. The value is between 1 and 4094 inclusive, and it represents an 802.1Q VLAN-ID with global scope within a given bridged domain. Sampling is performed on all packets received that are part of the specified VLAN (no matter which port they arrived on). Each packet will only be considered once for sampling, irrespective of the number of ports it will be forwarded to. - entPhysicalEntry. A dataSource of this form refers to a physical entity within the agent (e.g., entPhysicalClass = backplane(4)) and is called an 'entity-based' dataSource. Sampling is performed on all packets entering the resource (e.g. If the backplane is being sampled, all packets transmitted onto the backplane will be considered as single candidates for sampling irrespective of the number of ports they ultimately reach). Note: Since each DataSource operates independently, a packet that crosses multiple DataSources may generate multiple flow records.

sFlowOwner 1.3.6.1.4.1.4300.1.1.4.1.2
The entity making use of this sFlow sampler. The empty string indicates that the sFlow sampler is currently unclaimed. An entity wishing to claim an sFlow sampler must make sure that the sampler is unclaimed before trying to claim it. The sampler is claimed by setting the owner string to identify the entity claiming the sampler. The sampler must be claimed before any changes can be made to other sampler objects. In order to avoid a race condition, the entity taking control of the sampler must set both the owner and a value for sFlowTimeout in the same SNMP set request. When a management entity is finished using the sampler, it should set its value back to unclaimed. The agent must restore all other entities this row to their default values when the owner is set to unclaimed. This mechanism provides no enforcement and relies on the cooperation of management entities in order to ensure that competition for a sampler is fairly resolved.

  OwnerString  

sFlowTimeout 1.3.6.1.4.1.4300.1.1.4.1.3
The time (in seconds) remaining before the sampler is released and stops sampling. When set, the owner establishes control for the specified period. When read, the remaining time in the interval is returned. A management entity wanting to maintain control of the sampler is responsible for setting a new value before the old one expires. When the interval expires, the agent is responsible for restoring all other entities in this row to their default values.

sFlowPacketSamplingRate 1.3.6.1.4.1.4300.1.1.4.1.4
The statistical sampling rate for packet sampling from this source. Set to N to sample 1/Nth of the packets in the monitored flows. An agent should choose its own algorithm introduce variance into the sampling so that exactly every Nth packet is not counted. A sampling rate of 1 counts all packets. A sampling rate of 0 disables sampling. The agent is permitted to have minimum and maximum allowable values for the sampling rate. A minimum rate lets the agent designer set an upper bound on the overhead associated with sampling, and a maximum rate may be the result of hardware restrictions (such as counter size). In addition not all values between the maximum and minimum may be realizable as the sampling rate (again because of implementation considerations). When the sampling rate is set the agent is free to adjust the value so that it lies between the maximum and minimum values and has the closest achievable value. When read, the agent must return the actual sampling rate it will be using (after the adjustments previously described). The sampling algorithm must converge so that over time the number of packets sampled approaches 1/Nth of the total number of packets in the monitored flows.

sFlowCounterSamplingInterval 1.3.6.1.4.1.4300.1.1.4.1.5

sFlowMaximumHeaderSize 1.3.6.1.4.1.4300.1.1.4.1.6
The maximum number of bytes that should be copied from a sampled packet. The agent may have an internal maximum and minimum permissible sizes. If an attempt is made to set this value outside the permissible range then the agent should adjust the value to the closest permissible value.

sFlowMaximumDatagramSize 1.3.6.1.4.1.4300.1.1.4.1.7
