Sample-rate conguration
Sampling rate is the number of packets skipped before the sample is taken. If the sampling rate is 4096, one sample generates for every
4096 packets observed.
• Set the sampling rate in CONFIGURATION mode, from 4096 to 65535. The default is 32768.

Source interface conguration
You can congure an interface as a source for sFlow. The sFlow agent uses the IP address of the congured source interface as the agent
IP address.
• Congure the source interface in CONFIGURATION mode.
sflow source-interface {ethernet node/slot/port[:subport] | loopback loopback-ID| port-
channel
port-channel-ID| vlan vlan-ID}
