Default Level
1: Monitor level
Parameters
verbose: Displays detailed information about the NetStream cache.
slot slot-number: Displays the NetStream entry information in the cache of a specified device. The slot-number is the ID of a member device of the current the IRF virtual device, which you can display with the display irf command. The slot number range depends on the numbering rules and the number of member devices of the current IRF virtual device. If no IRF virtual device exists, the slot-number argument is the current device number.

Note that:
l The configuration in NetStream aggregation view applies to NetStream hardware aggregation, if enabled.
l The NetStream hardware aggregation data export and NetStream common data export are mutually exclusive. The hardware aggregation will not take effect if the destination address for NetStream common data export (ip netstream export host in system view) is configured.
l The NetStream hardware aggregation entries are stored in the cache where NetStream common data entries are recorded, and then exported.

Default Level
3: Manage level
Parameters
ip-address: Destination IP address for NetStream data export.
udp-port: Destination UDP port number for NetStream data export, in the range 0 to 65535.
vpn-instance vpn-instance-name: Name of the VPN in which routes are to be queried for NetStream data export.
Description
Use the ip netstream export host command to set the destination address for NetStream data export, and specify the VPN in which routes are to be queried.
Use the undo ip netstream export host command to delete a specified export address or all export addresses that are configured in this view.
By default, no destination host is configured in system view or in NetStream aggregation view.
Note that:
l If a NetStream aggregation is not enabled, the destination IP address and UDP port number for its data export cannot be displayed.
l Different destination addresses can be configured in different aggregation views.
l If no destination addresses is configured in aggregation view, the configuration in system view, if any, applies.
l Up to four different destination addresses, including addresses in different VPNs, can be configured in one aggregation view. If you have configured the destination addresses with the same IP addresses but different UDP port numbers, the latest configuration takes effect. If you configure different VPN names, you can configure destination hosts with the same IP address and UDP port number.
l NetStream common data is exported to all destination hosts configured in system view, while. NetStream aggregation data is exported to all destination addresses configured in the related aggregation view. If you expect NetStream aggregation data only, configure the destination address in the aggregation view and do not configure the destination host in system view; otherwise, the NetStream common data is also be exported, which will increase the bandwidth occupation.

Description
Use the ip netstream export source command to configure the source interface for NetStream data export.
Use the undo ip netstream export source command to remove the configuration.

Default Level
3: Manage level
Parameters
packets: Specifies the refresh frequency with which the version 9 templates are resent to the NetStream server for an update. That is, the template is resent every packets packets. It is in the range 1 to 600 and defaults to 20.
Description
Use the ip netstream export v9-template refresh-rate packet command to configure the refresh frequency with which a NetStream version 9 template is resent.
Use the undo ip netstream export v9-template refresh-rate packet command to restore the default.
By default, a version 9 template is resent every 20 packets.
Note that:
l Because version 9 is template-based and supports user-defined formats, the NetStream device needs to resend a new template to the NetStream server for an update. If the version 9 format is changed on the NetStream device and not updated on the NetStream server, the server is unable to associate the received statistics with its proper fields. To avoid such situation, you can configure the refresh frequency and rate for version 9 templates so that the NetStream server can refresh the templates on time.
l The refresh frequency and interval can be both configured, and the template is resent when either of the condition is reached.
Related commands: ip netstream export v9-template refresh-rate time.
Examples
# Set the packet refresh frequency to 100 so that a NetStream version 9 template is resent every 100 packets.

Parameters
minutes: Specifies the refresh interval at which the NetStream version 9 template is resent. In other words, the template is resent every minutes minutes. It is in the range 1 to 3600, and defaults to 30.
Description
Use the ip netstream export v9-template refresh-rate time command to configure the refresh interval at which a NetStream version 9 template is resent.
Use the undo ip netstream export v9-template refresh-rate time command to restore the default.
By default, a version 9 template is sent every 30 minutes.
Note that:
l Because version 9 is template-based and supports user-defined formats, the NetStream device needs to resend a new template to the NetStream server for an update. If the version 9 format is changed on the NetStream device and not updated on the NetStream server, the server is unable to associate the received statistics with its proper fields. To avoid such a situation, configure the refresh frequency and rate for version 9 templates so that the NetStream server can refresh the templates on time.
l The refresh frequency and interval can be both configured, and the template is resent when either of the condition is reached.

By default, NetStream common data export uses version 5; NetStream aggregation data export uses version 8; the AS number of the BGP peers is recorded, if any; the BGP next hop is not recorded.
Note that:
l The AS numbers for the source and destination IP addresses of a NetStream flow are recorded. Each IP address corresponds with two AS numbers (origin and peer), and the system records the AS numbers according to the configured AS option..
