Configuring NetFlow on the Matrix X Core Router
On the Matrix X Router, NetFlow classification and caching are performed on the Input/Output
Modules (IOMs), while NetFlow export functionality is performed on the Control Module (CM).
Packets are sampled at ingress at the rate configured for the whole system with the set
sampling‐rate command (see Procedure

Task
If using version 9, optionally modify the number
of export packets sent that cause a template to
be retransmitted by an individual DFE module
and/or the length of the timeout period, in
minutes, after which a template is retransmitted
by all modules in the system.
Verify any configuration changes made.
Description
Whether NetFlow caching is globally enabled or
disabled.
The IP address of the NetFlow collector which is the
destination of the NetFlow UDP packets.
The time out interval when the NetFlow cache is
flushed and the data is exported, if the maximum
number of entries has not been reached.
The NetFlow flow record format used when
exporting NetFlow packets. Version can be either 5
or 9.
The number of seconds after a flow stops before
NetFlow sends an export packet for that flow to the
collector.
Whether NetFlow is enabled or disabled on a port.
The number of export packets sent before NetFlow
retransmits a template to the collector when using
NetFlow Version 9.
When using NetFlow Version 9, the number of
minutes NetFlow waits before retransmitting a
template to the collector.
