现场两台设备做M-LAG，在设备上配置了netstream，现场发现两台设备只能收到端口出方向的流量
以5/0/1为例
#
interface Ten-GigabitEthernet5/0/1
port link-mode bridge
description To_NW_S7506XG
port link-type trunk
port trunk permit vlan all
ip netstream inbound
ip netstream outbound
mirroring-group 1 mirroring-port both
port link-aggregation group 1
#
已知限制，netstream入方向会计算成聚合口ifindex。

看入方向改成观察聚合口
