7.10.3.3 Counter Polling Configuration
To configure and start Counter Polling sampling, do the following:
1. Navigate to MONITOR > Tools > sFlow and select Counter Polling Configuration tab.
Figure 7-35 Counter Polling Configuration
2. From the Receiver Index drop-down box, choose the receiver index number associated with the sFlow Receiver to
which the sFlow Agent sends the counters.
: If Packet Flow Sampling is already configured and running, then you should configure the Receiver index same as
configured in the Packet Flow Sampling for each ethernet interface.
3. Set the polling interval by typing a value in the Interval box. Lets say, the polling interval is set to 30 seconds. So for
every 30 seconds, the counters are collected and send to the sFlow Receiver. The valid range for polling interval is 0 to
2
31
- 1 seconds.
4. Next, click Apply to start Counter Polling Sampling. Once it starts, the Time Out parameter (see sFlow Receiver
Configuration) keeps decrementing till it reaches a zero value. On reaching zero, the corresponding Receiver and
Counter Polling values are set to default values.
• Enabling sFlow counter sampling effects the system performance, and hence care must be taken when choosing the right
value sampling interval.
• Receiver Index for packet Sampling table and Counter Polling table should be same for each Ethernet interface.
• If a sampling starts and there is already another sampling running then we consider the time out value of the
current/already running sampling.
