Click the Collector link in the sFlow screen to display the screen as shown. You
can configure up to four sFlow collectors in this screen. You may want to configure
Active Select this to allow the Switch to monitor traffic on this port and generate
and send sFlow datagram to the specified collector.
Sample-rate Enter a number (N) from 256 to 65535. The Switch captures every one
out of N packets for this port and creates sFlow datagram.
poll-interval Specify a time interval (from 20 to 120 in seconds) the Switch waits
before sending the sFlow datagram and packet counters for this port to
the collector.
Collector
Address Enter the IP address of the sFlow collector.
Note: You must have the sFlow collector already configured in the
sFlow > Collector screen. The sFlow collector does not need
to be in the same subnet as the Switch, but it must be
accessible from the Switch.
Note: Configure UDP port 6343 (the default) on a NAT router to allow
port forwarding if the collector is behind a NAT router.
Configure a firewall rule for UDP port 6343 (the default) to
allow incoming traffic if the collector is behind a firewall.
Apply Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
