display ip netstream

Function

The display ip netstream command displays NetStream configurations. You can run this command in any interface view to display the NetStream information of a specific interface, or you can run this command in the system view or the aggregation view to display the system or aggregated NetStream information.

Format

display { ip | ipv6 } netstream { cache [ slot slot-id cpu cpu-id ] | export [ template ] }

Parameters

Parameter	Description	Value
ip	Indicates an IPv4 data flow.	-
ipv6	Indicates an IPv6 data flow. The NetStream aggregation view does not support this parameter.	-
cache	Displays the information about the NetStream cache of the NetStream board.	-
slot slot-id cpu cpu-id	Indicates the CPU that processes NetStream services. Only the USG6635E/6655E, USG6680E and USG6712E/6716E support this parameter.	slot 11 cpu 0 indicates the primary CPU. slot 12 cpu 0 indicates the secondary CPU.
export	Displays the information about the NetSteam statistics on outgoing packets.	-
template	Displays the information about the NetStream template.	-

Usage Guidelines

The display ip netstream command displays only the interface on which NetsStream sampling is configured

The displayed information covers the NetStream aging mode, the status of sampling for incoming IPv4 packets, the sampling mode, and sampling interval. If the interface is a Layer-2 interface, the ID of the VLAN that the Layer-2 interface belongs to is also displayed.

Example

# Displays the information about the NetStream cache.

<sysname> display ip netstream cache
