Table 175 SWITCHING > sFlow
LABEL DESCRIPTION
Active Enable the switch button to enable the sFlow agent on the Switch.
Port This field displays the port number.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
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 SWITCHING > 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.
