None

Create agent Role

The agent role is used to configure and manage the sampling. Currently, the network address type supported by the agent role can only be IPv4.

Table 6-2 Create the agent role

Create receiver Role

The receiver role is used to save the information of the third-party receiver and send the sFlow packets buffered on the device to the third-party receiver via the UDP mode. The triggering conditions of sending packets include the following two:

• When the specified buffer area is full and cannot be filled with new sFlow sampling information, first encapsulate the buffered part to the sFlow packet, send to the third- party receiver, and then fill the new part to the buffer area. This can reduce the number of the sFlow packets sent by the device to the third-party receiver obviously.
• Encapsulate the buffered sFlow sampling information as the sFlow packet periodically and send to the third-party receiver. This can avoid that the buffered part cannot be encapsulated as the sFlow packet and sent to the third-party receiver because of not receiving new sFlow sampling information within a long time.
