Usage Information
You can congure up to two sFlow collectors (IPv4 or IPv6). If two collectors are congured, trac samples are
sent to both.
The sFlow agent address is carried in a eld in SFlow packets and is used by the collector to identify the sFlow
agent.
In sFlow, the agent address is a single invariant IPv4 or IPv6 address used to identify the agent to the collector. It is
usually assigned the address of a loopback interface on the agent, which provides invariance. The agent address is
carried as a eld in the payload of the sFlow packets.
As part of the sFlow-MIB, if the SNMP request originates from a congured collector, Dell EMC Networking OS
returns the corresponding congured agent IP in the MIB requests. Dell EMC Networking OS checks to ensure
that two entries are not congured for the same collector IP with a dierent agent IP. Should that happen, Dell
EMC Networking OS generates the following error: %Error: Different agent-addr attempted for
an existing collector.
