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

Configures the IP address and UDP port used by the

sflow max-datagram-size

Configures the maximum size of the sFlow datagram

sflow max-header-size

Configures the maximum size of the sFlow datagram

Configures the name of the receiver

sflow sample

Configures the packet sampling rate

sflow source

Enables sFlow on the source ports to be monitored

sflow timeout

Configures the length of time samples are sent to the

Collector before resetting all sFlow port parameters

Shows the global and interface settings for the sFlow

This command configures the IP address and UDP port used by the

Collector. Use the no form to restore the default settings.

sflow destination {ipv4 ipv4-address | ipv6 ipv6-address}

[destination-udp-port]

no sflow destination

ipv4-address - IPv4 address of the sFlow Collector. Valid IPv4

addresses consist of four decimal numbers, 0 to 255, separated by

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.
