Since the template maychange after a period of time, the system needs to update the template on NSC bysome way.The system updates the template on NSC by:z Number of sent packets: When the number of sent Netstream packets exceedsthe threshold set by the ip netstream template refresh command, the systemsends the newest template to the NSC.z Template aging time: When the template aging time (set by the ip netstreamtemplate timeout command) expires, the system sends the newest template tothe NSC and resets the aging timer.Follow these steps to configure the ways to update the template for version 9Netstream packets:To do… Use the command… RemarksEnter system view system-view —Configure a packetthreshold for updating thetemplate of version 9Netstream packetsip netstream templaterefresh packetsOptionalBy default, the packetthreshold is 20 packets.
