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:
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.
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.
