2.2.9 Configuring the Ways to Update the Template for Version 9 Netstream
Packets
When an NSC receives a Netstream packet of version 9, it identifies the information
fields in the packet based on the template carried in the packet. Since the template may
change after a period of time, the system needs to update the template on NSC by
some way.
The system updates the template on NSC by:
z Number of sent packets: When the number of sent Netstream packets exceeds
the threshold set by the ip netstream template refresh command, the system
sends the newest template to the NSC.
z Template aging time: When the template aging time (set by the ip netstream
template timeout command) expires, the system sends the newest template to
the NSC and resets the aging timer.
Follow these steps to configure the ways to update the template for version 9
