Flow sampling (sFlow) can be used with a remote sFlow Collector to
provide an accurate, detailed and real-time overview of the types and
levels of traffic present on the network. The sFlow Agent samples 1 out of
n
packets from all data traversing the switch, re-encapsulates the samples as
sFlow datagrams and transmits them to the sFlow Collector. This sampling
occurs at the internal hardware level where all traffic is seen, whereas
traditional probes only have a partial view of traffic as it is sampled at the
monitored interface. Moreover, the processor and memory load imposed by
the sFlow agent is minimal since local analysis does not take place.
sflow destination
This command configures the IP address and UDP port used by the
Collector. Use the
no
form to restore the default settings.

ipv4-address
- IPv4 address of the sFlow Collector. Valid IPv4
addresses consist of four decimal numbers, 0 to 255, separated by
periods.
ipv6-address
- IPv6 address of the sFlow Collector. A full IPv6
address including the network prefix and host address bits. An IPv6
address consists of 8 colon-separated 16-bit hexadecimal values.
