Parameters

inbound: Filters incoming traffic.

outbound: Filters outgoing traffic.

acl acl-number: Specifies an ACL by its number.

· For a basic or an advanced ACL, the value range is 2000 to 3999.

· For an Ethernet frame header ACL, the value range is 4000 to 4999.

Usage guidelines

IPv6 NetStream filtering uses an ACL to identify intended packets.

· If you want to collect data for specific flows, use the ACL permit statements to identify the flows. IPv6 NetStream collects data only for these flows.

· If you do not want to collect data for specific flows, use the ACL deny statements to identify the flows. IPv6 NetStream does not collect data for these flows.

· Enable or disable the specified IPv6 NetStream aggregation mode.

· Configure source interface, destination IPv6 address, and destination port for the IPv6 NetStream data export.

A flow matching multiple aggregation modes is counted as multiple aggregate flows.

Examples

# Set the IPv6 NetStream aggregation mode to destination-prefix, and enter the IPv6 NetStream AS aggregation mode view.

Syntax

ipv6 netstream export host { ip-address | ipv6-address } udp-port [ vpn-instance vpn-instance-name ]

undo ipv6 netstream export host [ ip-address | ipv6-address ] [ vpn-instance vpn-instance-name ]

Default

No destination host is specified.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

ip-address: Specifies the destination IP 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 cannot use the display ipv6 netstream export command to display information about the IPv6 NetStream aggregation mode that is not enabled.

You can specify the same destination host in different IPv6 NetStream aggregation mode views.

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 system view or in IPv6 NetStream aggregation mode view. If you specify a destination host with the same IPv4 addresses but different UDP ports, the most recent configuration takes effect. You can specify destination hosts with the same IPv4 address and UDP port but different VPN instances.

You can specify a maximum of four destination hosts in system view or in IPv6 NetStream aggregation mode view. If you specify a destination host with the same IPv6 addresses but different UDP ports, the most recent configuration takes effect. You can specify destination hosts with the same IPv6 address and UDP port but different VPN instances.

IPv6 NetStream traditional data are exported to all destination hosts in system view. IPv6 NetStream aggregation data are exported to all destination hosts in the related aggregation view.

If you expect only IPv6 NetStream aggregation data, you can specify destination hosts only in the IPv6 NetStream aggregation mode view. This setting reduces bandwidth usage.

Examples

# In system view, specify 1.1.1.1 as the IP address of the destination host and UDP port 5000 as the export destination port number.

<Sysname> system-view

[Sysname] ipv6 netstream export host 1.1.1.1 5000

# In destination-prefix aggregation mode view, specify 1.1.1.2 as the IP address of the destination host and UDP port 6000 as the export destination port number.

Parameters

rate: Specifies the maximum rate for exporting IPv6 NetStream data, in the range of 1 to 1000 (maximum number of packets per second).

Examples

<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 remove the configuration.

Syntax

ipv6 netstream export source interface interface-type interface-number

undo ipv6 netstream export source

Default

No source interface is specified for IPv6 NetStream data packets. The packets take the primary IPv6 address of the output interface as the source IPv6 address.

Views

System view, IPv6 NetStream aggregation mode view

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 1/0/1 as the source interface for IPv6 NetStream traditional data packets.

<Sysname> system-view

[Sysname] ipv6 netstream export source interface gigabitethernet 1/0/1

# In destination-prefix aggregation mode view, specify GigabitEthernet 1/0/2 as the source interface for IPv6 NetStream aggregation data packets.

Use undo ipv6 netstream export v9-template refresh-rate packet to restore the default.

Predefined user roles

network-admin

Parameters

packets: Specifies the number of packets that are sent before version 9 templates are sent to NetStream servers for an update. The value range is 1 to 600.

Usage guidelines

An IPv6 NetStream server uses version 9 templates to parse the data from the NetStream device, but the server does not permanently save version 9 templates.

For an IPv6 NetStream server to use correct version 9 templates, configure the refresh frequency or refresh interval for version 9 templates. If both settings are configured, templates are sent when either of the conditions is reached.

To configure the refresh interval for version 9 templates, use the ipv6 netstream export v9-template refresh-rate time command.

Examples

# Configure the device to send IPv6 NetStream version 9 templates every 100 packets.

<Sysname> system-view

[Sysname] ipv6 netstream export v9-template refresh-rate packet 100

Related commands

ipv6 netstream export v9-template refresh-rate time

Syntax

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

Parameters

origin-as: Exports statistics of the source AS originating the route for the source address and the destination AS for the destination address.

peer-as: Exports statistics of the peer ASs for the source and destination address.

bgp-nexthop: Exports statistics of BGP next hops.

Usage guidelines

An IPv6 NetStream entry for a flow 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.

When you execute the command without any keywords, the peer AS numbers are recorded, and the BGP next hop is not recorded.
