Sampling Traffic Flows
– 149 –
As the Collector receives streams from the various sFlow agents (other switches or
routers) throughout the network, a timely, network-wide picture of utilization and
traffic flows is created. Analysis of the sFlow stream(s) can reveal trends and
information that can be leveraged in the following ways:
◆ Detecting, diagnosing, and fixing network problems
◆ Real-time congestion management
◆ Understanding application mix (P2P, Web, DNS, etc.) and changes
◆ Identification and tracing of unauthorized network activity
◆ Usage accounting
◆ Trending and capacity planning
Configuring sFlow
Receiver Settings
Use the Interface > sFlow (Configure Receiver – Add) page to create an sFlow
receiver on the switch.
Parameters
These parameters are displayed:
◆ Receiver Owner Name
2
– The name of the receiver. (Range: 1-256 characters;
Default: None)
◆ Receiver Timeout – The time that the sFlow process will continuously send
samples to the Collector before resetting all sFlow port parameters.
(Range: 30-10000000 seconds, where 0 indicates no time out)
The sFlow parameters affected by this command include the sampling interval,
the receiver’s name, address and UDP port, the time out, maximum header size,
and maximum datagram size.
◆ Receiver Destination
2
– IP address of the sFlow Collector.
■
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. One double colon may be
used to indicate the appropriate number of zeros required to fill the
undefined fields.
◆ Receiver Socket Port
2
– The UDP port on which the sFlow Collector is listening
for sFlow streams. (Range: 1-65535)
2. Sampling must be disabled by setting the time out to 0 before these fields can be
configured.
