DESCRIPTION
|
||
|
|
"Identifies a source of sFlow data.
|
||
|
|
|
||
|
|
The following data source types are currently defined:
|
||
|
|
|
||
|
|
- ifIndex.<I>
|
||
|
|
SFlowDataSources 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 allows 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.
|
||
|
|
- sFlowFsPacketSamplingRate applies to all ports on the
|
||
|
|
device capable of packet sampling.
|
||
|
|
|
||
|
|
- smonVlanDataSource.<V>
|
||
|
|
An SFlowDataSource of this form refers to a 'Packet-based VLAN'
|
||
|
|
and is called a 'VLAN-based' dataSource. <V> 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.<N>
|
||
|
|
An SFlowDataSource 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 SFlowDataSource operates independently a
|
||
|
|
packet that crosses multiple DataSources may generate
|
||
|
|
multiple flow records."

DESCRIPTION
|
||
|
|
"Identify the sFlow receiver associated with this resource.
|
||
|
|
|
||
|
|
A value of zero indicates that this resource is available.
|
||
|
|
If non-zero the value must correspond to a valid, active
|
||
|
|
sFlowRcvrIndex.
|
||
|
|
|
||
|
|
If the value is currently zero it may be set to any
|
||
|
|
active entry in the sFlowRcvrTable. If the value is
|
||
|
|
not zero then a set to anything other than zero or
|
||
|
|
its current value will result in an SNMP error (bad value).
|
||
|
|
|
||
|
|
Setting to zero frees the resource and returns all the
|
||
|
|
values in this entry to their default values.
|
||
|
|
|
||
|
|
If an entry in the sFlowRcvrTable expires, either
|
||
|
|
because the sFlowRcvrOwner is set to the empty
|
||
|
|
string or because the sFlowRcvrTimeout reaches zero, then
|
||
|
|
the agent must mark all associated resources as available
|
||
|
|
(by setting the associated SFlowReceiver entry to zero)
|
||
|
|
and all values in these records must be restored to their
|
||
|
|
default values.
|
||
|
|
|
||
|
|
This mechanism provides no enforcement and relies on the
|
||
|
|
cooperation of management entities in order to ensure that
|
||
|
|
competition for a resource is fairly resolved. A management
|
||
|
|
entity should not make any changes to a resource
|
||
|
|
without first aquiring it by successfully writing its
|
||
|
|
sFlowRcvrIndex value as the SFlowReceiver for the resource."

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

Management entities must check the MIB Version and not attempt

they were designed.

DESCRIPTION

"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 to 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."
