We have achieved data sampling and statistic targeting physical port.
Our data sample includes the IPv4 and IPv6 packets. Extensions of other types are
not supported so far. As for non IPv4 and IPv6 packet, the unify HEADER mode will be
adopted following the requirements in RFC3176, copying the head information of the
packet based on analyzing the type of its protocol.
The latest SFLOW protocol presented by Inmon company is the version 5. Since it is
the version 4 which is realized in the RFC3176, version conflict might exist in some case
such as the structure and the packet format. This is because the version 5 has not
become the official protocol, so, in order to be compatible with current applications, we
will continue to follow the RFC3176.
2.8.2 sFlow Configuration Task
1. Configure sFlow Collector address
Command
Explanation
Global mode and interface mode
sflow destionation <collector-address>
[<collector-port>]
no sflow destionation
Configure the IP address and port number
of the host in which the sFlow analysis
software is installed. As for the ports, if IP
address is configured on the port, the port
configuration will be applied, or else will be
applied the global configuration. The “
no
sflow destionation
” command restores to
the default port value and deletes the IP
address.
2. Configure the sFlow proxy address
Command
Explanation
Global Mode
sflow agent-address
<collector-address>
no sflow agent-address
Configure the source IP address applied by
the sFlow proxy; the “no” form of the
command deletes this address.
3. Configure the sFlow proxy priority
Command
Explanation
Global Mode
sflow priority <priority-vlaue>
no sflow priority
Configure the priority when sFlow receives
packet from the hardware; the “
no sflow
