Figure 6-126. sFlow Sampler Summary Configuring and Viewing sFlow Settings Using CLI Commands For information about the CLI commands that perform this function, see the sFlow Commands chapter in the CLI Reference Guide. The following table summarizes the equivalent CLI commands you use to configure and view sFlow settings. Table 6-65. sFlow Settings Commands CLI Command sflow sampling show sflow sampling show sflow polling Description Enables a new sflow sampler instance for this data source if rcvr_idx is valid. Displays the sFlow sampling instances created on the switch. Displays the sFlow polling instances created on the switch. sFlow Poll Configuration The sFlow agent collects time-based sampling of network interface statistics and sends them to the configured sFlow receivers. A data source configured to collect counter samples is called a poller. Counter Sampling The primary objective of Counter Sampling is to efficiently, periodically export counters associated with Data Sources. A maximum Sampling Interval is assigned to each sFlow instance associated with a Data Source. Counter Sampling is accomplished as follows: The sFlow Agent keeps a list of counter sources being sampled. When a Packet Flow Sample is generated, the sFlow Agent examines the list and adds counters to the sample datagram, least recently sampled first. Counters are only added to the datagram if the sources are within a short period, i.e. five seconds, of failing to meet the required Sampling Interval. Periodically, i.e. every second, the sFlow Agent examines the list of counter sources and sends any counters that need to be sent to meet the sampling interval requirement.
