The statistics of the flow are sent to NetStream servers and are cleared in the cache. The
statistics can no longer be displayed by using the
display ipv6 netstream cache
command.
When you use the inactive flow aging method, the cache is large enough for new flow entries.
•
Active flow aging
—A flow is active if packets arrive for the IPv6 NetStream entry within the
period specified by using the
ipv6 netstream timeout active
command. When the active flow
aging timer expires, the statistics of the active flow are exported to NetStream servers. The
device continues to collect 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 aging
To implement forced aging, use the
reset ipv6 netstream statistics
command. This command ages
out all IPv6 NetStream entries, and exports and clears the statistics.
