To configure the agent to forward these port statistics to the collectors, you
have to specify polling rates, which define the maximum amount of time
permitted between successive queries of the counters of a port by the
agent.
Different ports can have different polling rates. Ports to which critical
network devices are connected can be assigned low polling rates, so that
the information on the collector is kept up-to-date. Ports connected to less
critical devices can be assigned higher polling rates.
To increase its efficiency, the agent can send port status and counter
information before the polling interval of a port times out. For example, if
you define a polling interval of five minutes for a port, the agent, depending
on its internal dynamics, may send the information to the collector before
five minutes have actually elapsed.
sFlow Collectors The sFlow agent on the switch can send port performance data to an
sFlow collector on your network. The performance data from each port can
be sent to one collector.
Guidelines Here are the guidelines for the sFlow agent:
You can specify just one sFlow collector.
The sFlow collectors must be members of the same subnet as the
management IP address of the switch, or must have access to it
through routers or other Layer 3 devices.
If the sFlow collectors are not a member of the same subnet as the
management IP address of the switch, the switch must have a default
gateway that specifies the first hop to reaching the collectors’ subnet.
For instructions, refer to Chapter 19, “Setting IPv4 and IPv6
Addresses” on page 229.
The sFlow feature is not dependent on SNMP. You do not have to
enable or configure SNMP on the switch to use the sFlow feature. In
addition, you cannot use sFlow collectors to configure or manage
SNMP.
