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, Dell Networking OS returns
the corresponding configured agent IP in the MIB requests. Dell Networking OS checks to ensure that two entries
are not configured for the same collector IP with a different agent IP. Should that happen, Dell Networking OS
generates the following error: %Error: Different agent-addr attempted for an existing
collector.
Use this command in Configuration Terminal Batch mode to configure the sFlow collectors in a dual-homing setup.
