Predefined user roles

network-admin

Parameters

ipv4-address: Specifies the destination IPv4 address.

ipv6-address: Specifies the destination IPv6 address.

udp-port: Specifies the destination UDP port number in the range of 0 to 65535.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the destination host belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this option.

Usage guidelines

You can specify the same destination host address and UDP port in different IPv6 NetStream aggregation mode views. If an aggregation mode is not enabled, the display ipv6 netstream export command cannot display the destination host configuration for the mode.

If no destination host is specified in an IPv6 NetStream aggregation mode view, the destination host in system view applies. If destination hosts are specified in an IPv6 NetStream aggregation view and system view, the destination hosts in aggregation view take effect.

You can specify a maximum of four destination hosts in an IPv6 NetStream aggregation mode view. Each destination host is identified by an IP address, a UDP port number, and an optional network identifier (VPN instance).

·          Destination hosts on different networks (VPN instances or public network) can use the same IP address and UDP port number.

·          Within the same VPN instance or the public network, each destination host must use a unique IP address. If you specify a destination host with the same IP address but different UDP port numbers, the most recent configuration takes effect.

IPv6 NetStream aggregation data is exported to all destination hosts in the related IPv6 NetStream aggregation mode view.

Examples

# In AS aggregation mode view, specify 40::1 as the IPv6 address of the destination host and UDP port 5000 as the export destination port number.

<Sysname> system-view

Parameters

ipv4-address: Specifies the destination IPv4 address.

ipv6-address: Specifies the destination IPv6 address.

udp-port: Specifies the destination UDP port number in the range of 0 to 65535.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the destination host belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this option.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command applies to all cards. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command applies to all cards. (In IRF mode.)

Usage guidelines

You can specify destination hosts in system view with or without a designated slot (card). The destination hosts specified for a card are always preferred for exporting IPv6 NetStream data of that card.

IPv6 NetStream traditional data is exported to all destination hosts specified in system view for the specified slot. If no destination host is specified for the slot, the destination hosts specified without a designated slot are used.

For IPv6 NetStream aggregation data export, the system chooses the destination hosts in the following order:

1.        Destination hosts specified in the IPv6 NetStream aggregation mode view.

2.        Destination hosts specified in system view for the specified slot.

3.        Destination hosts specified in system view without a designated slot.

You can specify a maximum of four destination hosts in system view for the same slot. Each destination host is identified by an IP address, a UDP port number, and an optional network identifier (VPN instance).

·          Destination hosts on different networks (VPN instances or public network) can use the same IP address and UDP port number.

·          Within the same VPN instance or the public network, each destination host must use a unique IP address. If you specify a destination host with the same IP address but different UDP port numbers, the most recent configuration takes effect.

Examples

# In system view, specify 40::1 as the IPv6 address of the destination host and UDP port 5000 as the export destination port number.

<Sysname> system-view

[Sysname] ipv6 netstream export host 40::1 5000

Parameters

rate: Specifies the export rate in the range of 1 to 1000.

Usage guidelines

This command sets the maximum number of IPv6 NetStream packets that can be exported per second. Packets that cannot be exported due to the export rate limit are buffered for later export. When the buffer is full, the system will temporarily invalidate the rate limit and export packets as fast as possible until the buffer has available free space.

Examples

# Allow a maximum of 10 packets to be exported per second.

<Sysname> system-view

[Sysname] ipv6 netstream export rate 10

ipv6 netstream export source

Use ipv6 netstream export source to specify the source interface for data packets sent to NetStream servers. The IPv6 address of the interface is used as the source IPv6 address of the data packets.

Use undo ipv6 netstream export source to restore the default.

Syntax

ipv6 netstream export source interface interface-type interface-number

undo ipv6 netstream export source

Default

The packets take the IPv6 address of the output interface as the source IPv6 address.

Parameters

interface-type interface-number: Specifies a source interface by its type and number for the IPv6 NetStream data export.

Usage guidelines

You can configure different source interfaces in different IPv6 NetStream aggregation mode views.

If no source interface is configured in IPv6 NetStream aggregation mode view, the source interface in system view applies.

As a best practice, connect the management Ethernet interface to a NetStream server, and configure the interface as the source interface.

Examples

# In system view, specify GigabitEthernet 3/1/1 as the source interface for IPv6 NetStream traditional data packets.

<Sysname> system-view

[Sysname] ipv6 netstream export source interface gigabitethernet 3/1/1

# In AS aggregation mode view, specify GigabitEthernet 3/1/2 as the source interface for IPv6 NetStream aggregation data packets.

ipv6 netstream export template refresh-rate

Use ipv6 netstream export template refresh-rate to set the refresh rate for the IPv6 NetStream version 9 or version 10 template.

Use undo ipv6 netstream export template refresh-rate to restore the default.

Syntax

ipv6 netstream export template refresh-rate { packet packets | time minutes }

undo ipv6 netstream export template refresh-rate { packet | time }

Default

The packet count-based refresh rate is 20 packets, and the time-based refresh interval is 30 minutes.

Views

System view

Predefined user roles

network-admin

Parameters

packet packets: Specifies the number of packets that are sent before the template is sent. The value range is 1 to 600.

time minutes: Specifies the interval at which the template is sent, in the range of 1 to 3600 minutes.

Usage guidelines

Version 9 and version 10 are template-based and support user-defined formats. An IPv6 NetStream device must send the version 9 or version 10 template to NetStream servers regularly, because the servers do not permanently save templates.

The refresh rate can be packet count-based or time-based. If both settings are configured, the template is sent when either of the conditions is met.

Examples

# Configure the device to send the IPv6 NetStream version 9 or version 10 template every 100 packets.

<Sysname> system-view

[Sysname] ipv6 netstream export template refresh-rate packet 100

ipv6 netstream export version

Use undo ipv6 netstream export version to restore the default.

Syntax

ipv6 netstream export version { 9 | 10 } { origin-as | peer-as } [ bgp-nexthop ]

undo ipv6 netstream export version

Default

The version 9 format is used to export IPv6 NetStream data.

The peer AS numbers are recorded.

The BGP next hop information is not recorded.

network-admin

Parameters

origin-as: Records the original AS numbers for the flow source and destination.

peer-as: Records the peer AS numbers for the flow source and destination.

bgp-nexthop: Records the BGP next hop information.

Usage guidelines

Only one version format can take effect on the device. If you execute this command multiple times, the most recent configuration takes effect.

An IPv6 NetStream entry records the source IPv6 address, destination IPv6 address, and two AS numbers for each address. You can choose to configure which AS numbers are to be exported as the source AS and destination AS.

Examples

# Configure the device to export IPv6 NetStream data in the version 9 format, and specify the IPv6 NetStream data to include the source AS and destination AS.
