Currently, only the sFlow agent function is supported on the device. 

 

sFlow operates as follows: 

1)  With sFlow enabled, a physical port encapsulates sampled data into packets and sends them to 

the sFlow agent. 

2)  The sFlow agent periodically collects the statistics of all sFlow enabled ports. 

3)  When the sFlow packet buffer overflows or the one-second timer expires, the sFlow agent sends 

sFlow packets to the specified sFlow collector. 

The sFlow feature enables the remote sFlow collector to monitor the network and analyze sFlow packet 

statistics. 

Follow these steps to configure sFlow: 

Enter system view 

— 

Specify the IP address of the 
sFlow agent 

sflow agent { ip ip-address | 
ipv6 ipv6-address } 

Required 

Not configured by default. 

Specify the IP address and port 
number of the sFlow collector 

sflow collector { ip ip-address  
| ipv6 ipv6-address } [ port 
port-num ] 

Required 

Not specified by default. 

Set the counter sampling 
interval at which the sFlow 
agent collects the statistics of 
sFlow enabled ports 

sflow interval interval-time 

Optional 

20 seconds by default. 

Enter interface view 

interface interface-type 
interface-number 

— 

Enable sFlow in the inbound or 
outbound direction 

sflow enable { inbound | 
outbound } 

Required 

Not enabled by default. 

Specify the sFlow sampling 
mode 

sflow sampling-mode 
{ determine | random } 

Optional 

random by default. 

Currently, the determine mode 
is not supported on S7900E 
series Ethernet switches. 

Specify the number of packets 
out of which the interface will 
sample a packet 

sflow sampling-rate rate  

Optional 

200000 by default.
