Ip Netstream Filter - H3C SR6600 Command Reference Manual

Usage guidelines
A NetStream entry for a flow records the source IP address and destination IP address, and two AS
numbers for each IP address. You can choose to configure which AS numbers to be exported as the
source AS and destination AS.
Examples
# Configure the device to export NetStream data in version 5 format and to specify the NetStream data
to include the source AS and destination AS.
<Sysname> system-view
[Sysname] ip netstream export version 5 origin-as

ip netstream filter

Use ip netstream filter to enable ACL-based NetStream filtering on an interface.
Use undo ip netstream filter to disable the function.
Syntax
ip netstream filter acl acl-number { inbound | outbound }
undo ip netstream filter acl acl-number { inbound | outbound }
Default
NetStream filtering is disabled. NetStream collects statistics about all IPv4 packets passing through the
interface.

Default command level
3: Manage level
Parameters
acl acl-number: Specifies an ACL number in the range of 2000 to 3999.
inbound: Filters incoming traffic.
outbound: Filters outgoing traffic.
Usage guidelines
The NetStream filtering function is not effective on MPLS packets.
If NetStream filtering and sampling are both configured, packets are filtered first and then the permitted
packets are sampled.
An ACL referenced by NetStream filtering must already exist and this command takes effect only after the
ACL is created. An ACL that is referenced by NetStream filtering cannot be deleted or modified. For more
information about ACLs, see ACL and QoS Configuration Guide.
Examples
# Reference ACL 2003 to enable NetStream filtering in the outbound direction of GigabitEthernet
2/0/0.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/0
[Sysname-GigabitEthernet2/0/0] ip netstream outbound
