| LABEL | DESCRIPTION |
| Enter a number (N) from 256 to 65535. The Switch captures every one | |
|
| out of N packets for this port and creates sFlow datagram. |
|
|
|
| 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 | Enter the IP address of the sFlow collector. |
| Address |
|
|
| 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 |
|
| 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. |
