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 
more than one collector if the traffic load to be monitored is more than one 
collector can manage.

Figure 155   Advanced Application > sFlow > Collector 

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.
