You can perform H3C S12500 (sFlow) configuration using the following steps:
system-view
sflow agent ip {LOOPBACK_IP}
sflow source ip {LOOPBACK_IP}
sflow collector 1 ip {NETFLOW_SERVER_IP} port {NETFLOW_SERVER_LISTENER_PORT}
Enter global configuration mode on the router or MSFC, and issue the following commands for each interface on which you want to enable flow:
interface {INTERFACE_NAME}
sflow sampling-mode random
sflow sampling-rate 512
sflow flow max-header 128
sflow flow collector 1
sflow counter interval 60
sflow counter collector 1
