ipv6 netstream export host

Syntax

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

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

View

System view, NetStream aggregation view

Default level

3: Manage level

Parameters

ip-address: Destination IP address for IPv6 NetStream data export. Only IPv4 addresses are supported.

udp-port: Destination UDP port number for IPv6 NetStream data export, in the range 0 to 65535.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN that the IPv6 NetStream data export destination belongs to. 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.

Description

Use ipv6 netstream export host to set the destination address for IPv6 NetStream data export.

Use undo ipv6 netstream export host to delete the specified export address or all export addresses that are configured in this view.

By default, no destination address is configured in system view, and the destination address in aggregation view is that configured in system view.

Different destination hosts can be configured in different aggregation views.

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 ports, the last configuration takes effect. If you configure different VPN instance names, you can configure destination addresses with the same IP address and UDP port.

IPv6 NetStream traditional data are exported to all destination addresses configured in system view, and IPv6 NetStream aggregation data are exported to all destination addresses configured in the related aggregation view. If you expect IPv6 NetStream aggregation data only, configure the destination address in the aggregation view, and do not configure the destination address in system view; otherwise, the IPv6 NetStream traditional data are also be exported, which will increase the bandwidth occupation.

Related commands: ipv6 netstream aggregation and ipv6 netstream export source.

Examples

# Configure the destination IP address and UDP port number for NetStream export data as 1.1.1.1 and 5000 respectively, and query routes in vpn1.

Parameters

rate: Maximum rate for exporting IPv6 NetStream data, in the unit of the maximum number of packets per second. It is in the range of 1 to 1000.

Description

Use ipv6 netstream export rate to configure the limit on the IPv6 NetStream data export rate.

Use undo ipv6 netstream export rate to remove the IPv6 NetStream data export limit.

By default, the export rate of NetStream data is not limited.

The export rate on each card is different. Because the aging timer is different, the configuration may not be very precise on a multi-CPU router.

Examples

# Allow 10 packets at most to be exported per second.

<Sysname> system-view

[Sysname] ipv6 netstream export rate 10

ipv6 netstream export source

undo ipv6 netstream export source

View

System view, NetStream aggregation view

Default level

3: Manage level

Parameters

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

Description

Use ipv6 netstream export source to configure the source interface for NetStream data export.

Use undo ipv6 netstream export source to remove the configured source interface.

By default, the interface (where the NetStream data is sent out) connecting to the NetStream server is used as the source interface.

Different source interfaces can be configured in different aggregation views.

If no source interface is configured in aggregation view, the source interface configured in system view is used.

H3C recommends you connect the network management interface to the NetStream server and configure it as the source interface.

Related commands: ipv6 netstream aggregation.

Examples

# Configure the source interface for NetStream data export as M-Ethernet 6/0/0.

ipv6 netstream export v9-template refresh-rate packet

Syntax

ipv6 netstream export v9-template refresh-rate packet packets

undo ipv6 netstream export v9-template refresh-rate packet

View

System view

Default level

3: Manage level

Parameters

packets: Specifies the number of packets that are sent before version 9 templates are sent to the NetStream server for an update. It is in the range of 1 to 600.

Description

Use ipv6 netstream export v9-template refresh-rate packet to configure the refresh frequency for NetStream version 9 templates so that the templates are sent when the specified number of packets are sent.

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

By default, version 9 templates are sent every 20 packets.

Version 9 is template-based and supports user-defined formats, so the NetStream-enabled router needs to send the new template to the NetStream server for an update. If the version 9 format is changed on the router and not updated on the NetStream server, the server is unable to associate the received statistics with its proper fields. To avoid such situation, configure the refresh frequency for version 9 templates so that the NetStream server can refresh them on time.

The refresh frequency and interval can be both configured, and the template is resent when either of the condition is reached.

Related commands: ipv6 netstream export v9-template refresh-rate time.

Examples

# Configure the router to wait until 100 packets are sent before sending NetStream version 9 templates again to the NetStream server.

<Sysname> system-view

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

View

System view

Default level

3: Manage level

Parameters

minutes: Specifies the refresh interval in minutes that the router waits after NetStream version 9 templates are sent to the NetStream server. It is in the range of 1 to 3600.

Description

Use ipv6 netstream export v9-template refresh-rate time to configure the refresh interval for NetStream version 9 templates so that the templates are sent after the specified time period.

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

By default, version 9 templates are resent every 30 minutes.

Version 9 is template-based and supports user-defined formats, so the NetStream-enabled router needs to send the new template to the NetStream server for an update. If the version 9 format is changed on the router and not updated on the NetStream server, the server is unable to associate the received statistics with its proper fields. To avoid such situation, configure the refresh interval for version 9 templates so that the NetStream server can refresh them on time.

The refresh frequency and interval can be both configured, and the template is resent when either of the condition is reached.

Related commands: ipv6 netstream export v9-template refresh-rate packet.

Parameters

origin-as: Specifies to record the statistics about source autonomous system (AS) and destination AS.

peer-as: Specifies to record the statistics about the peer ASs.

bgp-nexthop: Specifies to record the statistics about BGP next hops.

Description

Use ipv6 netstream export version 9 to export IPv6 NetStream data in version 9 format, and choose whether to record data about AS and BGP next hop information.

Use undo ipv6 netstream export version to restore the default.

By default, version 9 format is used to export IPv6 NetStream traditional data, IPv6 NetStream aggregation data, and MPLS flow data with IPv6 fields; the peer AS numbers are recorded; the BGP next hop is not recorded.

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

Examples

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

· Collection of NetStream MPLS packet statistics is supported only when NetStream is enabled.

· To collect statistics about MPLS packets carrying IPv4 data, enable IPv4 NetStream.

· To collect statistics about MPLS packets carrying IPv6 data, enable IPv6 NetStream.

· To collect statistics about MPLS packets carrying neither IPv4 nor IPv6 data, enable IPv4 NetStream.

· On a NAM card, to collect statistics about MPLS packets carrying non-IPv4 data, enable IPv4 NetStream. Only the statistics about labels are collected.

Examples

# Enable MPLS NetStream, and export MPLS packets with the first, second and third labels and IP contents being counted.
