If you choose Custom, you may set your own sampling interval and traffic sampling rate.
- Global Settings
• Counter sampling Interval - defines the interval in seconds between samples. The
range is 0 to 86400.
• Traffic sampling rate - the ratio between the total number of incoming packets and the
number of flow samples taken at the product level. The ratio is expressed as n to 1; for
example, if you specify a sampling rate of 100, the ratio is 100:1. The lower the ratio,
the higher the demand on CPU resources to process the samples. The range is 1
through 1048576.
- Port Level Settings
• Apply sFlow forwarding settings - This check box is used to enable traffic sampling at
the port level using the rate value specified in the sFlow forwarding sampling rate
field.
• sFlow forwarding sampling rate - the ratio between the total number of incoming
packets and the number of flow samples taken at the port level. The ratio is expressed
as n to 1; for example, if you specify a sampling rate of 100, the ratio is 100:1. The
lower the ratio, the higher the demand on CPU resources to process the samples.
• Disable sFlow forwarding - disables port level sampling.

a. Use the IP Address selector to select an IP address from the existing list of IP addresses of
management server NICs, or enter a new IP address in the field. IPv4 and IPv6 addresses
are allowed. IPv6 addresses are not supported for Network OS previous to v4.0 and Fabric
OS previous to v7.2.
b. Enter the port number in the UDP Port field for the UDP port used to forward sFlow
samples to the collector.
NOTE
VCS devices use the default port 6343. If you change the VCS device default port number,
all sflow configuration are deployed to the device except the port number. The 6343 port
number cannot be changed.
