233collect its statistics, which can be displayed by using the display ipv6 netstream cache command.The active flow aging method periodically exports the statistics of active flows to NetStream servers.Forced agingTo implement forced aging, use one of the following commands:• Use the reset ipv6 netstream statistics command. This command ages out all IPv6 NetStream entries,and exports and clears the statistics.• Use the ipv6 netstream max-entry command. This command provides the following processingoptions when the upper limit is reached:{ Age out the entries.{ Disable creation of a new entry in the cache.TCP FIN- and RST-triggered agingTCP FIN- and RST-triggered aging is automatically performed when a TCP connection is terminated.A TCP connection is terminated when a packet with a FIN or RST flag is received.When a packet with a FIN or RST flag is recorded for a flow with an existing IPv6 NetStream entry, theentry is immediately aged out, exported, and cleared. However, when the first packet of a flow has a FINor RST flag, a new IPv6 NetStream entry is created instead of being aged out. This type of aging isenabled by default, and is not user-configurable.Configuration procedureTo configure IPv6 NetStream flow aging:Step Command Remarks1. Enter system view. system-view N/A2.
