HUAWEI NetEngine5000E Core Router
Configuration Guide - System Management
A maximum of two destination IP addresses can be configured for NSC backup. If the router
already has two destination IP addresses, delete one of the existing destination IP addresses
before changing the destination IP address of the output NetStream original flows.
Step 6 (Optional) Configure parameters for aging original flows as needed.

6.5.3 (Optional) Adjusting the AS Field Mode and Interface Index
Type
To enable the NSC to normally receive and parse NetStream packets output from the NDE,
ensure that the AS field modes and interface index types on the NDE are the same as that on the
NSC.
Context
To enable the NSC to normally receive and parse NetStream packets output from the NDE,
ensure that the AS field modes and interface index types on the NDE and NSC are the same.

ipv6 netstream timeout active active-interval
The active aging time is configured for NetStream original flows.
ipv6 netstream timeout inactive inactive-interval
The inactive aging time is configured for NetStream original flows.
The default active aging time of NetStream original flows is 30 minutes and the default
inactive aging time is 30 seconds.
AS field mode: As defined in the pertaining protocol, the length of the AS field in IP packets
is 16 bits. On networks in some areas, however, the length of the AS field in IP packets is
32 bits. If different AS field modes exist on a network, you need to convert the AS field
mode when configuring NetStream. Otherwise, NetStream cannot sample inter-AS traffic.
CAUTION
On a network where the 32-bit AS field mode is used, the NMS needs to identify the 32-
bit AS field. Otherwise, the NMS will fail to identify inter-AS traffic sent from devices.
Interface index: The NMS uses the interface index carried in the NetStream packet output
from the NDE to query information about the interface from which the packet is output.
The interface index can be of 16 bits or 32 bits, which is determined by NMS devices of
different vendors. Therefore, the NDE needs to use a proper interface index type according
to the index parsing capability of the NMS. For example, if the NMS can parse a 32-bit
interface index, the interface index carried in the NetStream packet must be a 32-bit value.
