netstream

Function

The ip netstream command enables NetStream IPv4 to collect statistics about incoming or outgoing data flows on an interface.

The undo ip netstream command disables NetStream IPv4 from collecting statistics about incoming or outgoing data flows on an interface.

The ipv6 netstream command enables NetStream IPv6 to collect statistics about incoming or outgoing data flows on an interface.

The undo ipv6 netstream command disables NetStream IPv6 from collecting statistics about incoming or outgoing data flows on an interface.

By default, NetStream is disabled from collecting statistics about incoming or outgoing data flows on an interface.

Format

ip netstream { inbound | outbound }

Usage Guidelines

Usage Scenario

When a specified interface needs to monitor or analyze features of incoming or outgoing data flows, and statistics collected by NetStream are output in original flows or aggregated flows, the command can be used to enable NetStream to collect statistics about incoming or outgoing data flows on the interface.

Configuration Impact

After NetStream is enabled to collect statistics about incoming or outgoing data flows, statistics about unicast and multicast packets are collected.

Precautions

This command is not supported by the management network port.
NetStream sampling function cannot be configured on a channelized sub-interface with network slicing configured.

Example

# Enable IPv4 NetStream to collect statistics about incoming or outgoing data flows on GE 0/1/0.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/0
[*HUAWEI-GigabitEthernet0/1/0] ip netstream inbound
[*HUAWEI-GigabitEthernet0/1/0] ip netstream outbound

# Enable NetStream to collect statistics about incoming or outgoing data flows on VE sub-interface.

<HUAWEI> system-view
[~HUAWEI] interface virtual-ethernet 0/1/0.1
[~HUAWEI-Virtual-Ethernet0/1/0.1] ip netstream inbound
[*HUAWEI-Virtual-Ethernet0/1/0.1] ip netstream outbound

# Enable IPv6 NetStream to collect statistics about incoming or outgoing data flows on GE 0/1/0.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/0
[*HUAWEI-GigabitEthernet0/1/0] ipv6 netstream inbound
[*HUAWEI-GigabitEthernet0/1/0] ipv6 netstream outbound
