6.10 Maintaining NetStream
This section describes how to maintain NetStream.
6.10.1 Aging Original Flows Forcibly
Original flows in the buffer in a specified slot can be aged forcibly so as to output original flows
or generate aggregated flows.
Issue 01 (2011-10-15)
The output of TAL options is enabled, and the corresponding TAL option template is
sent to the NSC.
By default, the output of TAL options is disabled.
2.
Run:
ip netstream export template option { refresh-rate packet-number | timeout-
rate timeout-interval }
The packet interval and time interval at which the TAL option template is refreshed
are set.
TAL option packets are separately output to the NSC in V9 format. To ensure that the
NSC can successfully parse the TAL option packets, it is required that the
corresponding TAL option template be sent to the NSC.
The TAL option template can be refreshed at both the fixed packet and time intervals.
Packet and time intervals can both be configured, without affecting each other.
– refresh-rate packet-number: indicates that the TAL option template is refreshed
at the fixed packet interval.
– timeout-rate timeout-interval: indicates that the TAL option template is refreshed
at the fixed time interval.
By default, the TAL option template is refreshed at intervals of 20 packets and 30
minutes.
