Configuring sFlow
– 215 –
the monitored interface. Moreover, the processor and memory load
imposed by the sFlow agent is minimal since local analysis does not take
place. The wire-speed transmission characteristic of the switch is thus
preserved even at high traffic levels.
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

PARAMETERS
These parameters are displayed:
Receiver Configuration
◆ Owner – sFlow can be configured in two ways: Through local
management using the Web interface or through SNMP. This read-only
field shows the owner of the current sFlow configuration and assumes
values as follows:
■
If sFlow is currently unconfigured/unclaimed, Owner shows
<none>.
■
If sFlow is currently configured through the Web, Owner shows
<Configured through local management>.
■
If sFlow is currently configured through SNMP, Owner contains a
string identifying the sFlow receiver.
If sFlow is configured through SNMP, all controls, except for the
Release-button, are disabled to avoid inadvertent reconfiguration.
The Release button can be used to release the current owner and
disable sFlow sampling. This button is disabled if sFlow is currently
unconfigure. If configured through SNMP, the release must be
confirmed (a confirmation request will appear).
◆ IP Address/Hostname – The IP address or host name of the sFlow
receiver. Both IPv4 and IPv6 addresses are supported.
