8.1.1.0 Introduced on the E-Series.
7.7.1.0 Introduced on the S-Series.
7.6.1.0 Introduced on the C-Series.
6.5.1.0 Expanded the no form of the command to mirror the syntax used to congure.
6.2.1.1 Introduced on the E-Series.
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 Networking OS returns
the corresponding congured agent IP in the MIB requests. Dell 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 Networking OS
generates the following error: %Error: Different agent-addr attempted for an existing
collector.
Example
Dell(conf)# sflow collector 10.1.1.25 agent-addr 10.1.1.10 vrf management
sow enable (Global)
Enable sFlow globally.
Syntax
sflow enable
To disable sFlow, use the no sflow enable command.
Defaults Disabled.
