Usage
Information
You can configure up to two sFlow collectors (IPv4 or IPv6). If two collectors are configured,
traffic samples are sent to both.
The sFlow agent address is carried in a field 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 field in the payload of the sFlow
packets.
As part of the sFlow-MIB, if the SNMP request originates from a configured collector, FTOS
returns the corresponding configured agent IP in the MIB requests. FTOS checks to ensure
that two entries are not configured for the same collector IP with a different agent IP. Should
that happen, FTOS generates the following error: %Error: Different agent-addr
attempted for an existing collector
.
