Configured sampler type on the port and could be any of the types: None, Rx, Tx or All.
You can scroll to choice one for your sampler type.
By default, the value is “None”.
z Sampling Rate :
Configured sampling rate on the ports.
z Max Hdr Size :
Configured size of the header of the sampled frame.
z Counter Sampling :
Counter sampling performs periodic, time-based sampling or polling of counters associated
with an interface enabled for sFlow.Attribute associated with counter sampling is polling
interval.
z Polling Interval :
Configured polling interval for the counter sampling.
Parameter description:
z sFlow Ports :
This is the port number on which sFlow can be configured.
z sFlow Instance :
Multiple instances of sFlow can be supported on the port. Currently we support one sFlow
instance on each port due to hardware limitation.
z Sampler Type :
Sampler type on the port can be one of the following types: None, RX, TX, ALL. If type is
"none" then the sampling rate is 0 and no other value is accepted. The default value is
"none".
z Sampling Rate :
Determines the rate at which samples must be taken on the ports. If sampling rate is
configured as 'N', 1/N frames is sampled.
The sampling rate ranges from 0 to 4095.
Default value is "0" meaning sampling is disabled on the port.
If receiver time_out is 0sec, this sFlow configuration is disabled operationally.
To make it operational the receiver time_out has to remain alive.
When operational, the sample rate 'N' is rounded off to the nearest possible value.
z Max Hdr Size :
Configures the size of the header of the sampled frame to be copied to the Queue for
further processing.
The Max header size ranges from 14 to 200 bytes.
Default is 128 bytes.
z Polling Interval :
Configures the polling interval for the counter sampling. It decides at what regular intervals
the counter should be polled for statistics.
The accepted value for Counter Polling Interval ranges from 0 to 3600 seconds.
Default is 0 seconds which means polling is disabled.
